Six Sigma Terms: What is TRIZ – The Theory of Inventive Problem Solving?
TRIZ, also known as the theory of inventive problem solving, is a technique that fosters invention for project teams who have become stuck while trying to solve a business challenge. It provides data on similar past projects that can help teams find a new path forward.
TRIZ (pronounced “trees”) started in Russia. It involves a technique for problem solving created by observing the commonalities in solutions discovered in the past. Created by Genrich Altshuller in the former Soviet Union, the Six Sigma technique recognizes that certain patterns emerge whenever inventions are made.
Features of the Technique
Altshuller found that almost every invention falls into one of 40 categories. Each is an area where invention and innovation took place. They include areas such as weight, length and area of moving and stationary objects, speed of the object, temperature illumination intensity, ease of operation and ease of repair.
In practical use, a project team stymied by a challenge can use TRIZ to analyze a matrix of similar challenges and their solutions.
When TRIZ Is Used
TRIZ operates on the idea that someone, somewhere, likely came up with a solution for the challenge you currently face or something similar. Another guiding principle is that contradictions should not be accepted, but rather resolved.
It also provides an answer for those concerned that Six Sigma stifles innovation . TRIZ encourages innovation. As pointed out in a paper on TRIZ conducted by researchers at the University of Belgrade and Metropolitan University in Serbia, not all solutions involving Six Sigma can be found in the process itself.
This “inhibits the ability to identify the control variables. In this case, a methodology that can solve the problem outside of the process boundaries, such as TRIZ, is necessary,” the researchers wrote.
Essentially, TRIZ offers a sophisticated, effective tool for clearing roadblocks.
The Benefits of TRIZ
TRIZ works best in situations where other Six Sigma tools have not accomplished the task. It provides another way to find solutions during the improve phase of the Six Sigma technique DMAIC (define, measure, analyze, improve, control) or the design phase of DMADV (define, measure, analyze, design, verify).
TRIZ allows project teams to globalize an issue and find examples of how people have solved similar challenges. It’s a bit like the old saying, “There’s no need to reinvent the wheel.” It’s possible that teams won’t have to develop a solution on their own, because it’s already been done. On the other hand, knowing the possible combination of the 40 categories that might apply to a specific issue can also spark new ideas.
How TRIZ Works and Examples
TRIZ translates problems from the specific to the generic. It then compares the current challenge with 40 different inventive solutions. This is because in his research, Altshuller found that:
- Problems and solutions repeat across industries and sciences.
- Patterns of technical evolution repeat across industries and sciences.
- Innovations used scientific effects outside the field where they were developed.
It also supplies potential solutions to apparently contradictory issues, such as wanting a more powerful engine that is lighter or wanting something to both operate faster and more accurately.
Most examples for TRIZ involve solving engineering issues, such as the invention of a new type of self-heating container as detailed by TRIZ Journal or creation of automation that can handle the simultaneous filing of 10 interlinked plastic cups with paint.

The Theory of Inventive Problem Solving
Solving problems creatively using the triz method.
TRIZ, The Theory of Inventive Problem Solving, is by definition a theory used for solving problems creatively and represents a new way of thinking about and approaching innovation based on the objective nature of technological analysis .
According to TRIZ, universal principles of creativity form the basis of innovation. TRIZ identifies and codifies these principles, using them to make the creative process more predictable. Part of solving problems creatively, then, is finding existing solutions that can be adapted to the specific problem.
With TRIZ, we improve the performance of our technological products and processes in UMBRAGROUP, reducing costs and waste by analyzing a specific problem, abstracting it as a general problem of a principle, identifying models for solving the problem using the TRIZ problem-solving principles, and lastly, applying the most effective solution to the initial problem. The fundamental steps of the TRIZ method are:
- defining the specific problem;
- finding the corresponding generalized TRIZ problem;
- finding the generalized solution to the generalized problem;
- adapting the generalized solution to the specific problem.
We also use TRIZ to generate new ideas and products, to meet client requirements, and in market research. When generating ideas with the TRIZ method, people from all areas of the company are involved, not just those in engineering or sales. In this way, it is a powerful method that encourages thinking outside the box and facilitates team building within the Group .

Discover the Power of The Theory of Inventive Problem Solving (TRIZ)
Updated: March 4, 2023 by Ken Feldman
Sometimes you really need to look at problems in a creative and innovative manner. TRIZ is a problem-solving approach that fosters invention for project teams who have become stuck while trying to solve a business challenge.
TRIZ (Teoriya Resheniya Izobretatelskikh Zadach) is a problem-solving methodology that was developed in the former Soviet Union by Genrich Altshuller and his colleagues in the mid-20th century. TRIZ is a system of tools and techniques for innovation and inventive problem-solving, based on the analysis of millions of patents across different industries and disciplines.
Overview: What is TRIZ?
TRIZ was developed by the Soviet inventor and science fiction writer Genrich Altshuller and his associates. He started developing TRIZ in 1946 while doing work for the Soviet Navy . His job was to help with the development of invention proposals, document them, and to prepare applications to the patent office. He realized that a problem requires an inventive solution if there are unresolved contradictions created when improving one parameter negatively impacts another.
TRIZ is based on the idea that there are universal principles of innovation that can be learned and applied to any problem, regardless of the field or domain. TRIZ aims to help individuals and organizations to systematically identify and overcome contradictions or obstacles in their systems or processes, in order to achieve better performance, efficiency, and effectiveness.
The TRIZ methodology is composed of several stages, which include problem formulation, analysis, ideation, and evaluation. TRIZ provides a set of techniques to help individuals and teams to identify and resolve contradictions, such as the contradiction matrix, the 40 principles, and the separation principles, among others.
TRIZ has been used by many organizations around the world, including Samsung, Intel, and Procter & Gamble, to improve their products and processes, and to develop innovative solutions to complex problems.
5 benefits of TRIZ
TRIZ offers several benefits to individuals and organizations, including:
1. Improved problem-solving
TRIZ provides a systematic approach to problem-solving that helps to identify the underlying causes of a problem and to generate innovative solutions that are more effective, efficient, and elegant.
2. Increased creativity
TRIZ provides a set of tools and techniques for ideation and creativity, such as the contradiction matrix, the 40 principles, and the separation principles, among others. These tools can help individuals and teams to break free from conventional thinking and to generate novel ideas.
3. Reduced time and cost
TRIZ can help to reduce the time and cost of innovation by providing a systematic approach to problem-solving that is based on the analysis of millions of patents across different industries and disciplines. This can help to avoid reinventing the wheel and to leverage existing knowledge and solutions.
4. Enhanced innovation
TRIZ provides a framework for innovation that is based on the identification and resolution of contradictions or obstacles in a system or process. This can help to create new products and services, to improve existing ones, and to develop new business models and strategies.
5. Increased collaboration
TRIZ provides a common language and framework for problem-solving that can help to foster collaboration and communication between individuals and teams from different disciplines and backgrounds. This can help to break down silos and to create a more innovative and collaborative culture.
Why is TRIZ important to understand?
TRIZ is important to understand for several reasons:
TRIZ provides a systematic approach to problem-solving that can help individuals and organizations to identify and resolve contradictions or obstacles in their systems or processes. This can lead to more effective and efficient solutions.
TRIZ can provide a competitive advantage to individuals and organizations that can use the methodology to develop innovative solutions to complex problems. This can help to create new markets, to improve existing products and services, and to increase profitability.
TRIZ helps model problems that are not well defined into a specific problem that can be solved by any engineer.
An industry example of TRIZ
An automotive company had a product innovation need related to the gas cap, so they brought a team together and used TRIZ to develop an innovative solution.
First, they generated a problem statement. Multiple customer complaints state that gas caps are hard to install, easy to forget, make your hands smell like gas, and make the check engine light appear if not properly closed.
Next, they generated a conflict statement. We want to make it easy to add gas to the automobile but not at the expense of safety and functionality.
The team went to the contradictions matrix and selected the contradictions from the list of 39 that best fit the conflict statement. They then set the contradictions. First, the feature to improve. Next, the feature to preserve. Next, they narrowed down the relevant Inventive Principles. The Contradictions Matrix pointed to applicable Inventive Principles based on the contradictions above
Finally, they expanded the 3-4 Inventive Principles and brainstormed solutions. The solution was to use a spring-loaded flap in the fill nozzle. The flap seals the fuel tank in place of the gas cap.
6 best practices when thinking about TRIZ
Here are some best practices for using TRIZ effectively:
1. Clearly define the problem
Before applying TRIZ, it is important to clearly define the problem or challenge that needs to be solved. This includes understanding the root cause of the problem, the desired outcome, and any constraints or limitations.
2. Use a systematic approach
TRIZ provides a systematic approach to problem-solving, and it is important to follow this approach to ensure that all aspects of the problem are considered. This includes defining the problem, analyzing the problem, generating ideas, evaluating the ideas, and implementing the solution.
3. Collaborate with others
TRIZ is best used in a collaborative environment, where individuals with different perspectives and experiences can contribute to the problem-solving process. This can help to generate more diverse and innovative solutions.
4. Leverage the TRIZ tools and techniques
TRIZ provides a range of tools and techniques that can be used to generate innovative solutions, such as the contradiction matrix, 40 inventive principles, and separation principles. It is important to be familiar with these tools and techniques and to use them appropriately in the problem-solving process.
5. Apply TRIZ to a variety of problems
TRIZ can be applied to a wide range of problems, including technical, business, and organizational problems. By applying TRIZ to a variety of problems, individuals and organizations can develop a deeper understanding of the methodology and how it can be used to generate innovative solutions.
6. Continuously improve the problem-solving process
Like any methodology, TRIZ can be improved and refined over time. It is important to reflect on the problem-solving process and to identify areas for improvement. This can help individuals and organizations to become more efficient and effective in using TRIZ to solve problems.

Wrapping up TRIZ
TRIZ (pronounced TREEZ) is the Russian acronym for the Theory of Inventive Problem Solving. This proven approach to solving technical problems began in 1946 when Genrikh Altshuller, a Soviet engineer, inventor, and writer, studied thousands of patents and noticed certain patterns. From these patterns he discovered that the evolution of a technical system is not a random process but is governed by certain objective laws. These laws can be used to consciously develop a system along its path of technical evolution – by determining and implementing innovations .
TRIZ works best in situations where other Six Sigma tools have not accomplished the task. It provides another way to find solutions during the Improve phase of the Six Sigma technique DMAIC (define, measure, analyze, improve, control) or the design phase of DMEDI (define, measure, explore, develop, implement).

The Origins of TRIZ
Beginning in 1946 and still evolving, TRIZ was developed by the Soviet inventor Genrich Altshuller and his colleagues. TRIZ in Russian = Teoriya Resheniya Izobretatelskikh Zadatch or in English, The Theory of Inventive Problem Solving. Years of Russian research into patents uncovered that there are only 100 known solutions to fundamental problems and made them universally available in three TRIZ solution lists and the Effects Database .
Through enabling clear thinking and the generation of innovative ideas, TRIZ helps you to find an ideal solution without the need for compromise. However it is not a Theory - it is a big toolkit consisting of many simple tools - most are easy to learn and immediately apply to problems. This amazing capability helps us tackle any problem or challenge even when we face difficult, intractable or apparently impossible situations.
TRIZ helps us keep detail in its place, to see the big picture and avoid getting tripped up with irrelevance, waylaid by trivial issues or seduced by premature solutions. It works alongside and supports other toolkits, and is particularly powerful for getting teams to work together to understand problems effectively, collectively generate ideas and innovate.
Developed by Oxford Creativity, Oxford TRIZ™ is simpler than standard or classic TRIZ. Its tools and processes are faster to learn and easier to apply. Oxford TRIZ is true to classic TRIZ (neither adding nor removing anything) but it delivers:
More powerful results
Faster and easier ways to learn and apply triz, step-by-step processes for applying triz toolkits, 'at a glance' understanding, supported by our hallmark commissioned cartoons (from clive goddard), philosophy of making every session effective, efficient and fun, gap-filling where other toolkits fall short.
TRIZ enthusiasts who have failed to use TRIZ effectively or to embed TRIZ into their organisations hail Oxford TRIZ as revelatory.
Very impressed with how Oxford Creativity has been able to create a methodology for applying TRIZ that can be widely used.
"I have learnt new and powerful ways of looking at problems differently to come up with new and viable solutions. It is a toolset that I think all engineers would find useful. "

History of TRIZ
How did triz start who was the founder altshuller.
It seems unfair that the work of Altshuller, perhaps one of the greatest engineers of the twentieth century remains quite obscure; especially as the his powerful findings enhances and transforms the work of managerial and technical teams in most countries of the world. He was a remarkable and charismatic man who innovated innovation and inspired many, as an inventor, teacher, and science-fiction author (Altov). The stories about Genrich Saulovich Altshuller (1926-1998) founder of TRIZ, derive mostly from those who worked with him, a community of Jewish intellectuals from Ukraine, Russia, and other countries once part of the Soviet Union. Many of these left Russia when they could, in the early 1990’s, taking TRIZ with them, to reach business and technical communities all over the world. Although TRIZ is a Russian acronym*, in today’s troubled world it is worth emphasising that TRIZ is much more Zelensky than Putin – as it was developed in a Siberian Gulag by those who stood up to Stalin.
Altshuller's groundbreaking work in the field of creative problem-solving derives from analysing the patent database and identifying and sharing the patterns of success in the world’s published knowledge. This is unlike most other creative techniques which cluster round brain prompts to improve brainstorming. TRIZ contains all these too, but they seem less significant than the power of the unique solution techniques uncovered by the TRIZ community in the last century.
Genrich Saulovich Altshuller was bought up in Baku, Azerbaijan, but was born in Tashkent, Uzbekistan on October 15, 1926, at those times both countries were a part of the Soviet Union. Just too young to serve in World War II, Altshuller was patenting his inventions from 1940 when he was just 14. He trained as a diver and electrician and later at the Azerbaijan Oil and Chemistry Institute in Baku. Altshuller joined the Soviet Navy as a mechanical engineer in his early twenties and worked in the Baku patent department, interacting with the Caspian Sea flotilla of the Soviet Navy where, as in all wars, creativity and invention flourished; this had a profound impact on his thinking and future endeavours. It was here that he began to formalize his Theory of Inventive Problem Solving, together with his colleague Raphael Shapiro. TRIZ was born out of the pair's aspiration to create a systematic approach to problem-solving that could replace the hit-or-miss strategies often used by inventors.
Altshuller’s genius observation of the frequent occurrence of identical solutions in different industries
Altshuller ’bottled’ the inventive process. He identified how frequently inventors duplicate each other’s work as they unknowingly reinvent the wheel. They fail to recognise that their efforts are repeating work already achieved (and documented), because their results are published in their own specialist technical language. Altshuller could see how science and engineering (by this time segmented and specialised) had become a ‘Tower of Babel’** because each discipline had its own different technical jargon. It was as if there were now many tribes in technology, with their own tribal language, which they used to write their papers and patents; (Chemists spoke chemistry and physicist spoke physics etc.). Altshuller showed that by stripping out details (which removed most technical jargon) both the problems being solved and their answers were revealed. This research showed that there are only about 100 fundamental ways to solve any problem. Altshuller and his teams gave these ‘ hundred answers to anything’ in three overlapping lists which show us how to:-
- Resolve contradictions (40 Principles)
- Invent future Products (8 Trends)
- Deal with Harms, boost insufficiencies and measure or detect (76 Standard Solutions)
These concept solutions underly all inventive problem-solving and they help us solve particular problems through using the TRIZ Contradiction Matrix and Separation Principles and TRIZ Function Mapping. Also there is the TRIZ Effects Database which answers ‘how to’ questions – so if we wanted to know how to ‘change viscosity’ it would show us all published ways and give an explanation of each. (see https://www.triz.co.uk/triz-effects-database )
Development of TRIZ:
Altshuller and his TRIZ community created their database of technical problems and solutions from various industries by undertaking an exhaustive study of patents, scientific literature, and innovation history. TRIZ ‘uncovered’ all the ways humankind knows to tackle tough challenges and was a vast collaboration of many (including Rafael Shapiro) to formalise the TRIZ methodology by identifying patterns and principles common to all successful inventive solutions. TRIZ aimed to stop needless time-wasting duplication by providing a systematic approach to enable anyone to overcome problems and recognise and resolve contradictions, deal with harms and barriers in their work.
Once built the TRIZ foundations were their gift to the world distilling a vast store of human wisdom into the 3 simple lists of TRIZ concepts. Some erroneously describe TRIZ as complicated because it derives from more rigour and research than all other toolkits put together, but its power is its logical steps and simplicity. It is as easy as learning chess - each tool is can be quickly understood to see how it can be ‘played’ in specific ways – the challenge is knowing how to combine the tools together. There are as many solutions to problems as outcomes in chess – mastering both takes quick learning (and talent?) and then as much practice as possible.
Despite its immense potential, TRIZ was not initially well-received by the Soviet government, Altshuller's claim that scientists and engineers duplicated each other’s work was unacceptable "non-conformist" thinking, and TRIZ was initially labelled as "bourgeois pseudoscience." Altshuller, along with several of his colleagues, often faced oppression, and their work was kept underground in several different periods. By the late 1940s Altshuller was arrested on political charges and spent time in the infamous Vorkuta Gulag in the Russian Arctic before being released in 1954 (after Stalin’s death). On his arrest the KGB ‘interviewed’ his widowed mother, killing her by pushing her from the balcony of her flat. Despite these setbacks, his determination to pursue his theories did not wane even in the Gulag which he described as his university of life.
Upon his release, Altshuller returned to his work with renewed vigour, working through thousands of patents, extracting their patterns of problem-solving into the TRIZ lists, and also uncovering the contradiction toolkit and the other creative concepts essential to tackling problems such as the Ideal and Ideality, Thinking in Time and Scale (9 boxes) plus many other tools for idea generation.
Recognition and success
Altshuller's determination prevailed, and in the 1960s, he managed to publish some of his TRIZ-related works. He also conducted lectures and workshops to disseminate the principles of TRIZ across the Soviet Union and beyond. His community expanded to include school children from his fortnightly TRIZ comics and his most famous book ‘And Suddenly the Inventor Appeared’. His ideas gained traction among engineers, leading to the formation of TRIZ associations and study groups. After 1990 the political reforms which swept the Soviet Union and its territories enabled TRIZ to surge in popularity and recognition. Altshuller's efforts were finally acknowledged, and he received numerous awards and honours for his groundbreaking work.
Genrich Altshuller's legacy lives on through TRIZ, which continues to influence problem-solving and innovation processes worldwide. TRIZ has been integrated into various industries, including engineering, product development, and management, allowing practitioners to find inventive solutions efficiently. It has proved an essential innovation toolkit in countries like South Korea, China and Japan where they have moved to the top of Patent league tables, pushing aside counties like the UK where there is no official or university take up (exceptions include the universities of Imperial and Bath). However one the world’s leading TRIZ consultancies is based in the UK and created the popular Oxford TRIZ TM. Russian TRIZ development seems to be detailed and complicated (the opposite of TRIZ simplicity)
Altshuller’s income derived more from his writings than his TRIZ work because he made TRIZ free to the world and public domain. Altshuller published so many books, articles, and scientific papers, which inspire and clarify the thinking of generations of inventors, innovators, and problem-solvers. In his later years he developed Parkinson’s disease, and he worked on sharing all the habits of geniuses and his last book was called ‘How to be a genius or heretic’ and he died on September 24, 1998, in Petrozavodsk, Russia. Altshuller's work has influenced numerous fields, including engineering, business strategy, and software development. Despite TRIZ being less known than other toolkit , his impact on the world remains undeniable if still largely under-appreciated. The power of TRIZ for boosting genius brain power, inventive problem-solving and innovation could change the world for the better if only it was known and accepted everywhere.

TRIZ – The Theory of Inventive Problem Solving
Posted by Tanner Zornes
TRIZ is a Russian acronym for The Theory of Inventive Problem Solving. TRIZ began in the 1940s by a soviet engineer named Genrich Altshuller. He recognized technology advancements follow a systematic and natural progression. As a result, Genrich invented TRIZ creating common solutions that can be re-deployed to business problems to specific improvements. The 40 Principles of TRIZ is like the old idiom, “don’t reinvent the wheel.”
In other words, there are hundreds of really smart inventors that lived before today. TRIZ takes what is already created, adapts, and deploys it to solve today’s problems. Moreover, TRIZ uses tables of inherent contradictions and innovation principles, not trial in error to reform the design challenge and remove physical contradictions.
- By this point in the DMAIC methodology, you should have a solid understanding of the problem that needs to be solved.
- Find the TRIZ General Problems that match your specific problem
- Identify which general solutions of TRIZ best applies to your specific problem
- Lastly, apply the general solutions to your specific problem
TRIZ works best in situations where other Six Sigma tools have not worked. Think of it as another way to find solutions that exist outside the normal process boundaries. You could make use of it during the Improve phase of the Six Sigma technique DMAIC (define, measure, analyze, improve, control) or the design phase of DMADV (define, measure, analyze, design, verify). ( reference )
As part of your Six Sigma preparation, you are not expected to memorize all 40 principles. Rather, you should be familiar with each TRIZ principle in order to recognize answers on the exam. With that said, each of the below principles have been paired with a brief explanation and examples.
Principle 1: Segmentation
Divide an object into similar section to add value to the product.
- Different sized cutting guards on hair clippers.
- Focal lenses on a camera
Principle 2: Taking Out or Extraction
Take out the unnecessary portions of a product or extracting the most necessary portions. As a result, the product becomes streamlined.
- Self check-in apps for dining-in restaurants (taking out long wait times)
- Music playing in restrooms (without the actual musicians)
- Take out lactose in milk and the result is a allergy-friendly milk
Principle 3: Local Quality
Adjust item properties to fit user/application requirements.
- Ergonomic keyboards
- Pens with erasable ink
Principle 4: Asymmetry
Modify an object from a balanced state to an uneven state. Though contrary to nature, asymmetry adds value to a variety of products.
- Water bottles (small spout for easy drinking, large base to hold water)
- Pencil Grips
Principle 5: Merging, Consolidation, or Combining
Combine concepts, items, or systems with those of similar properties. Consequently, the objective becomes more lean.
- Printers that can print in color and black and white
- Roofers that put up Christmas lights during the winter season
Principle 6: Universality
Consolidate parts of an object into one singular function. With this in mind, the product receives a wider application of use.
- A tablet compared to a laptop when you are on the go.
- USP drivers verses CDs or floppy disks.
Principle 7: Nested Doll
Similar to Russian nesting dolls, objects fit inside each other. This allows for space consolidation.
- A portable chess set:
- Stackable chairs
Principle 8: Anti-Weight
Offset an objects weight by combining it with things that provide lift. That is to say, the object has less weight.
- Hot air balloons
- Hydraulic car jacks
Principle 9: Preliminary Anti-action
Implement measures to control harmful actions or consequences DURING a necessary process.
- Cars with vehicle blind spot monitors in order to avoid collisions when changing lanes
Principle 10: Preliminary Action
Perform the required change in ADVANCE. To clarify, the action occurs before a process begins.
- Boxed furniture that contains pre-drilled holes for assembly
- Cell phone notification when power is low which prevents the phone from dying
Principle 11: Beforehand Cushioning
In cases where there is low consistency, provide a means for cushioning the worse-case scenarios
- Sprinkler systems in case of fires
- Emergency shut-off switches
Principle 12: Equipotentiality
Solutions that involve a change to the environment of an object, which enables the desired results compared to a direct change to the object.
- Laundry chute – using gravity to bring your laundry downstairs
Principle 13: The Other Way Around
Do it in reverse or the opposite way such as drive-thru restaurants vs. sit-in diners
Principle 14: Spheroidality – Curvature
Introduce a bend or shape to an object. In addition, this includes how the object moves.
- Archways expand the inside of buildings, which allows more room and improved acoustics
- Drill gun’s motion compared to a hammer’s motion
Principle 15: Dynamics
Change an object or system in order to create optimal flow.
- Pressure valves for gas and liquid control
Principle 16: Partial or Excessive Actions
If optimal performance cannot be achieved, aim for more or less to create the desired effect.
- Using paint primer on a object before the actual painting process
Principle 17: Another Dimension
Take an object from one dimension or plan to two planes. This includes two dimensions to three, or vice versa.
- Spiral staircase compared to normal stairs
- A desk shipped pre-assembled verses assembled in advance.
Principle 18: Mechanical Vibration
Introduce vibration to an object. Though contrary to Six Sigma’s goal to reduce process variation, increased vibration is beneficial under the right circumstances
- Electric toothbrush which allows for better teeth cleaning compared to a normal toothbrush

- Climbing the career ladder by changing jobs
Principle 35: Parameter Changes
Includes any input/output change such as temperature, durability, or pressure. Lots of things can fit in this bucket!
- Move into a larger work space in order to increase output
- Cakes batter baked at a lower temperature makes a better cake
Principle 36: Phase Transitions
Gradual changes to certain specs such as volume or pressure.
- Switching gears in a vehicle, which reduces gas consumption
- Move objects to cooler temperatures such as a fridge to decrease its heat
Principle 37: Thermal Expansions
Use heat or pressure in order to achieve desired results.
- Use heat to expand pipes so that they can connect. Cool pipes to cement them
Principle 38: Accelerated Oxidation
Replace common air with oxygen rich air.
- Ventilators assist to treat patients that struggle to breath
- Oxygen rich air is better fuel for fire, which can be applied during heat treatment
Principle 39: Inert Atmosphere
Negate moving or changing settings with less mobile or chemically inactive spaces
- Fire extinguishers work to move oxygen way from the flames. This results in putting out the fire
- Vacuum sealed bags are great space savers because the air is taken out of the object
Principle 40: Composite Materials
Unlike principle 5, composite materials combine different types of materials together.
- The body of an aircrafts is made of metals, foam, plastics, kevlar, and more. The principle also applies to the insides of vehicles.

- Reference work entry
How people invent? Famous scientists and engineers sharing their memories, as well as psychologists studying the creativity process, describe similar situations: An individual facing a difficult problem is mentally exploring various approaches, persistently trying and rejecting ideas until the right one comes. Psychologists call this process trial-and-error method (T&EM).
T&EM has a great history. It was used to create first stone knives, bows, guns, windmills, building, ships, and almost everything we can see around. Some results are astonishing: Polynesian catamarans, old Chinese, Norwegian, or Russian boats are practically perfect. Each element has the best shape. However, archeological research has shown that even 500 years ago, these vessels were rather far from perfect. One hundred years after another of repeating practically the same shapes, the builders yet were introducing slight changes into design. Some of them were unsuccessful,...
