Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Object-affected harmful factors

If traditional cutting fluid lubrication is used, then lubrication effect is achieved, but use cost is very high and environment is polluted

Engineering Contradiction:
Improveenvironmental pollutionVSAvoidcutting fluid consumption
Core Design Contradiction:
Object-affected harmful factorsVSQuantity of substance

Solution Approach 1:

The patent changes the physical state of lubricant from liquid cutting fluid to oil mist (aerosol form), and changes the delivery method from direct spraying to compressed air carrier. This parameter change reduces lubricant consumption from large amounts to small amounts while eliminating the harmful effects of liquid cutting fluid leakage and pollution.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses compressed air as a carrier gas to transport and deliver oil mist to the machining point. This pneumatic delivery system replaces the traditional liquid cutting fluid spraying system, enabling precise control of lubricant application and eliminating the need for large quantities of cutting fluid.

Inventive Principle:
Principle #29Pneumatics and hydraulics

2Temperature

If traditional cutting fluid is sprayed in large amounts, then cooling and lubrication are achieved, but cutting fluid flows away and leaks causing odor and health damage

Engineering Contradiction:
Improvecooling effectVSAvoidfluid leakage and odor
Core Design Contradiction:
TemperatureVSObject-generated harmful factors

Solution Approach 1:

The patent transforms the lubricant delivery from liquid spray to compressed oil mist, changing the physical parameters of delivery. The oil mist is carried by compressed air to the machining point, providing cooling and lubrication while preventing the leakage and odor problems associated with liquid cutting fluid.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent extracts only the necessary amount of lubricant (oil mist) and delivers it precisely to the machining point through compressed air carrier. This extraction approach eliminates the excess cutting fluid that would otherwise flow away, leak, and cause odor and health problems.

Inventive Principle:
Principle #2Taking out (Extraction)

3Manufacturing precision

If micro-lubrication technique is introduced, then lubricant permeability and cooling effect are improved, but device complexity increases

Engineering Contradiction:
Improvesurface machining qualityVSAvoidlubrication device structure
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent uses compressed air to serve multiple functions: as a carrier gas for oil mist delivery, as a cooling medium, and as a power source for the aerosol generation. This multi-functionality reduces the need for separate systems and simplifies the overall device structure despite the advanced lubrication technique.

Inventive Principle:
Principle #6Universality (Multi-functionality)
