Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If a conventional drill chuck structure is used, then the structure is simple and easy to manufacture, but the product temperature increases and service life reduces due to heat generation during processing

Engineering Contradiction:
Improveproduct temperatureVSAvoidservice life
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

The patent converts the harmful heat generated during drilling into a beneficial cooling effect by utilizing the rotational motion to drive air flow through the clamping jaw slope and back cover slope structures. The heat problem is transformed into a driving force for natural convection cooling, eliminating the need for external cooling systems while reducing product temperature and extending service life

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)

Solution Approach 2:

The drill chuck performs self-cooling by utilizing its own rotational motion to generate air flow through the specially designed slopes. The system serves itself by converting its operational energy into cooling action, with the clamping jaw slope and back cover slope automatically generating wind during rotation to cool the internal components without requiring external cooling devices

Inventive Principle:
Principle #25Self-service

2Temperature

If cooling mechanisms are added to reduce temperature, then product temperature decreases and service life improves, but device complexity increases

Engineering Contradiction:
Improveproduct temperatureVSAvoidstructure complexity
Core Design Contradiction:
TemperatureVSDevice complexity

Solution Approach 1:

The drill chuck performs self-cooling by utilizing its own rotational motion to generate air flow through the specially designed slopes. The system serves itself by converting its operational energy into cooling action, with the clamping jaw slope and back cover slope automatically generating wind during rotation to cool the internal components without requiring external cooling devices

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent extracts the cooling function from external cooling systems and integrates it into the basic structural components of the drill chuck. By modifying the clamping jaw and back cover with simple slope features, the cooling capability is extracted and built into the existing structure, avoiding addition of complex external cooling mechanisms

Inventive Principle:
Principle #2Taking out (Extraction)
