Explanation of the technical characteristics of the 39 TRIZ methods

good day (daytime greeting)39 technical characteristics in TRIZ　Here is a note about the

The technical characteristics of TRIZ method 39 are the definitions of technical characteristics that can be used in the "Engineering Contradiction Resolution Matrix" and have been used since ancient timesMany inventions have succeeded by resolving "contradictions.　The contradiction is a simple contradiction such as "improving A makes B worse.

You need to understand the correct definitions of those "A" and "B". Today I will explain the definition of those "39 technical characteristics" as concisely as possible.

39 technical characteristics

The way to use this is to use the "Engineering Contradiction Resolution Matrix" above, where "improving A makes B worse," and if you do this within the invention with a number in the corresponding square, about 1 to 4 numbers, there is a good chance that you can resolve the contradiction.

The numbers one through four in the "Engineering Contradiction Resolution Matrix" are "40 Inventive Principles of the TRIZ MethodThe "Mere Old Man" will be the "Mere Old Man". Please use it.

39 technical characteristics and their description

1. weight of moving object

The mass of an object in a gravitational field. The force acting on an object when it is supported or suspended.

2. weight of stationary object

The mass of an object in a gravitational field. The force acting on an object when it is supported or suspended, or on the surface on which it is placed.

3. length of moving object

Any linear dimension, not necessarily the longest.

4. length of stationary object

same as above

5. area of moving object

A graphic property indicated by the area enclosed by lines on a plane. The portion of a surface occupied by an object. Or, the surface area inside or outside an object.

6. area of stationary object

same as above

7. volume of moving object

The volume of space occupied by an object. For example, (length)x(width)x(height) for a rectangular object or (height)x(area) for a cylinder.

8. volume of a stationary object

same as above

9. speed

The speed of an object. The ratio of a process or action to time.

10. Strength

Force is the measure of action between systems. In Newtonian mechanics it is (force)=(mass)x(acceleration), but in TRIZ any action that attempts to change the state of an object is considered a force.

11. stress or pressure

Force per unit area. Tensile force is also included.

12. Shape

External and external appearance of the system.

13. stability of object composition

The integrity or intactness of the system. The relationship of the elements that make up the system. Wear, chemical degradation and decomposition all decrease stability. An increase in entropy also implies a decrease in stability.

14. Strength

The degree to which an object can resist being deformed by a force. Fragility.

15. movement time of moving object

The amount of time an object can operate. Service life. Mean time between failures is a measure of operating time. Duration.

16. motion time of stationary object

same as above

17.Temperature

Thermal conditions of an object or system. Other thermal parameters that affect the rate of change in temperature, such as heat capacity, can also be included.

18. luminance (illuminance)

Luminous flux per unit area. Or other illuminance characteristics of the system, such as brightness, light quality, etc.

19. energy consumption of moving objects

A measure of the ability of an object to perform work. In classical mechanics, energy is the product of force and distance. This parameter also includes energy supplied by the supersystem (electrical energy, heat, etc.). Energy required to perform a specific task.

20. energy consumption of stationary objects

same as above

21. output

Percentage of time, in which work is performed. Percentage of energy consumed.

22. energy loss

Energy consumption that does not contribute to the work being done. See parameter item 19. This is a separate item because reducing energy losses may require different techniques than improving energy consumption.

23. material loss

Partial or complete, temporary or permanent loss of system materials, substances, components, or subsystems.

24. information loss

Partial or complete, temporary or permanent loss of data or access to data by or of a system. Often includes perceptual data such as aroma, feel, etc.

25. time loss

Time refers to the duration of an activity. Improving time waste means reducing the time required for an activity. The expression "cycle time reduction" is often used.

26. Amount of substance

The number or amount of materials, substances, parts or subsystems of a system that can be changed, partially or completely, temporarily or permanently.

Reliability

The ability of a system to perform its intended functions in a predictable manner and condition.

28.Measurement Accuracy

The degree of approximation between measured and actual values for a system characteristic. Measurement accuracy is increased by reducing measurement error.

29. manufacturing accuracy

The degree to which the actual characteristics of a system or object match the specified or required characteristics.

30. detrimental factors to which objects are subjected

The degree to which a system is affected by externally generated (adverse) actions.

31. harmful factors emitted by objects

Harmful actions are those actions that reduce the efficiency or quality of the functioning of an object or system. These harmful actions are produced by the object or system as part of its operation.

32. ease of manufacture

Degree to which the object/system is easy, effortless, and simple to manufacture and assemble.

33. ease of operation

Simplicity. A process is not easy if it requires a large number of people, involves many steps in the operation, or requires special tools. A "difficult" process is less productive, while an "easy" process is more productive because it is easier to perform the correct operation.

34. ease of repair

Quality characteristics such as convenience, comfort, plainness, and time in repairing system defects, malfunctions, and scratches.

35. adaptability or flexibility

The degree to which a system/object reacts positively to external changes. Or, a system with multiple uses in diverse conditions.

36. complexity of the device

The number and variety of system components and interactions between elements. The users themselves can also be an element that increases the complexity of the system. The difficulty of mastering a system is a measure of its complexity.

37. difficulty of detection and measurement

Measurement and monitoring systems that are complex, expensive, time-consuming to set up and use, have complex relationships among components, and components that interfere with each other all indicate "detection and measurement difficulties. The increased cost of trying to keep within tolerances is another indication of measurement difficulties.

38. level (scope) of automation

The degree to which a system or object performs its function without human intervention. At the lowest level of automation, manually operated tools are used. At intermediate levels, a human programs the tool, watches over its operation, and interrupts or reprograms it as necessary. At the highest level, the machine senses the necessary actions, programs itself, and monitors its own actions.

39. productivity

The number of functions or actions performed by a system per unit of time. The time required for a single function or operation. The output per unit of time or the cost of one output.

*Mobile object: An object that can easily change its position in space by itself or by external forces. Vehicles and objects designed for portable use are typical of this category.
*Stationary object: An object that does not change its position in space by itself or by external forces. Determine this by considering the situation in which the object will be used.

That's it.
