Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If the driving motor case is formed of metal material, then heat dissipation is improved, but weight increases

Engineering Contradiction:

Core Design Contradiction:

TemperatureVSWeight of moving object

Solution Approach 1:

The fixing bracket is constructed using composite materials, specifically resin material, to replace traditional metal materials. This allows the motor case to maintain metal construction for heat dissipation while the bracket provides lightweight structural support, thereby resolving the contradiction between heat dissipation requirements and weight reduction

Inventive Principle:

Core Design Contradiction:

StrengthVSWeight of moving object

Solution Approach 1:

The fixing bracket undergoes parameter changes by transitioning from metal material to resin material. This material substitution maintains sufficient structural strength for motor fixation while significantly reducing the weight of the bracket, enabling easier storage and installation
