Principle
3. Local Quality
a. Transition from a homogeneous structure of an object or
outside environment
(outside action) to a heterogeneous structure
b. Have different parts of the object carry out different functions
c. Place each part of the object under conditions most favorable for its operation
- Principle Description: Change the characteristics of something (gas, liquid or solid) in a specific area (locally) in order to gain a required functionality.
- Hints on Usage: The name of this principle was translated word-for-word from Russian to English and as such, has the potential to convey an incomplete message. The name may be more appropriately called “Optimal Resource” because when using this principle the features are made non-uniform or optimal for each particular location and/or moment of time.
- Generally it is assumed that system characteristics are similar everywhere and all of the time. Although this assumption is simple and easy to imagine, it does not reflect reality. By applying The Local Quality principle, we consider improving or degrading the conditions of a characteristic in order to provide optimal function. For example, we have a large steel part that is subject to wear in a specific area while requiring work in another area. In order to reduce wear we could heat-treat a specific area (vary the interaction). And, in order to work in another area - such as drilling a hole in the hard material - we could anneal (soften) a specific spot.
- Thus we can achieve optimum functionality by varying interactions in different places (locations), at different moments (locality), for different features (characteristics). Providing optimal conditions (features) for each action might dramatically improve efficiency.
- To apply the Local Quality principle to a given system, identify a specific area that requires different conditions for optimal performance. Find a way to alter the conditions to achieve the desired results. Suggestions for altering conditions may include using different forms of energy, such as:
- Mechanical (burnishing, cold working)
- Thermal (heat treating, cryogenic treatment)
- Chemical (oxidizing)
- Electrical (electrostatic charge)
- Magnetic (selective magnetization)
- Electromagnetic (radiation treatment such as chemotherapy)
