The way to improve inventing and make it more efficient

Piotr Krystkowiak, E5109



TRIZ (Теория решения изобретательских задач) – Theory of inventive problem solving.

Complex tool helping with inventing in technic.

Based on research and observation made on 1 200 000 patents .

Clue how to solve problem by analyzing, splitting, changing, modifying …



1926 birth

1946 work in Soviet Army patent office.

1948 wrote a letter toStalin complainingabout lack ofdevelopment in

inventive. 1950 arrested for

“investor’s sabotage”

sent to the Gulag.



„ When technical systems develop accordingto some specified rules, then it is possible to

discover this rules to create algorythm ofsolving technical tasks.”



Trial and error method• Very expensive

• Takes long time

• Very inefficent

Modifying solutions already existed• Waste money for development inefficent ideas

• Strong influence of vector of intertia

Brainstorming

• Very random method

• Developed version of TAE method



Veryspecified

taskConotations

Narrow wayof thinking

Looking for

solution inalreadyexisted

inventions

Inefficientsolution

„Consuetudo est altera natura” - Cicero



Should be formed with as few words as possible

Non technical language

Shows the desired function not sollution

Should be as general as possible

Cannot narrow way of thinking

Cannot impose the solution

Cannot be specific

T a s k p r e

c i s i n gDefine final aim.

Check possibility ofusing alternative idea.

Check which methodgives better effects

Precise details .

Precise requirementsand conditions.

A n a l i t i c a

l s t a g e

Define IFR

Define obstacles

against IFRDefine why obstaclesapear?

Define conditions when IFR would berealised.

O p e r a t i o n a

l s t a g eCheck possibility of

using standards

Check possibility ofchanges in environemt

Adapt solution fromother technical branch

Check solutionreversed to solutionabove.

Look for solution in

natural environment.

Investigation



S y n t h e s i s s t a d i u m

What else should Ichange in object?

What should I

change incooperating objects?

Additional usage ofchanged object.

Use new idea forother technicaltasks

Designing solution



By analysing patents Altschuler realised that all of themare invented using only few techniques. After few years

of studying it turned out to be about 40 techniquesused to invent in technics. Now these techniques are

classified in table. They were also helpful with creatingof matrix of improvement/failure.



1. Segmentation

2. Extraction

3. Local quality

4. Asymmetry5. Combining

6. Universality

7. Nesting

8. Counterweight9. Prior counter-action

10. Prior action

11. Cushion in advance

12. Equipotentiality

13. Inversion

14. Spheroidality15. Dynamicity

16. Partial or overdoneaction

17. Move to new dimension18. Mechanical vibration

19. Periodic action

20. Continue useful action



21. Rushing through22. Convert harm to benefit

23. Feedback

24. Mediator

25. Self-service26. Copying

27. Substitute throwaway

28. Replace mechanicalsystem

29. Use pneumatic-hydraulicsystem

30. Flexible film or thinmembranes

31. Use porous material32. Change color

33. Make homogeneous

34. Rejecting or regenerating

parts35. Transform physical-

chemical states

36. Phase transition

37. Thermal expansion

38. Use oxidizers

39. Inert environment

40. Composite material



Su-Field (VePole in Russian) a minimal technical systemconsisting of two material objects (substances) and a "field"."Field" is the source of energy whereas one of the substancesis "transmission" and the other one is the "tool." Su-Fieldsare generally shown symbolically, where the specific field andsubstances for a given problem would be shown as relationsand actions beetwen substances and field.



SymbolsExample of use

S1 – painted part, S2 – paint

Pmech – mechanical influence on part



Efficience increase.

Faster designing andinventing.

Eliminates usage oftrial and error method.

Can be usedsimultanesly with

other inventingmethods.



Avoid connotation

Do not think in

regular categories

Precise technical problem

as a need to obtain pre-

defined features and

facilities



Engineering problem solving Product/process development

Cost reductions

Failure analysis and prevention

Hidden source of failures

Predict failures before they occur

Non-technical problem solving Education

Managment
