Transition from homogeneous to heterogeneous structure of an object or outside environment (action).
| In order to combat dust in coal mines, a cone shaped mist of water is sprayed over the working parts of drilling and loading machinery. The smaller the droplets, the greater the effect in combating dust. However, the fine mist hinders work. Solution: Spray a layer of coarse mist around the cone of fine mist. |

Different parts of an object should carry out different functions.
| A dust filter is made with porous membranes. The outer membrane has larger pores for preliminary filtration while the inner membrane has fine pores to collect small particulates. |

 |
Each part of an object should be placed in conditions that are most favorable for its operation.
| To reduce the temperature in an ultrasonic device for making holes, the middle section is made from heat conductive material while outer parts are made from wear resistant material. |

Principle Number: 3
Principle Name: Local Quality
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 thus 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 in time.
Generally, it is assumed that system characteristics are...
