Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a generator is disposed on the wheel to convert rotational kinetic energy into electrical energy, then energy recovery is improved, but heat dissipation capability deteriorates causing overheating risk
Solution Approach 1:
The cover mechanism incorporates an air permeable passage structure with porous characteristics that allows air to flow through the cover. This structure enables effective heat dissipation from the generator while maintaining the energy conversion function, resolving the contradiction between energy recovery and heat dissipation capability
Solution Approach 2:
The air permeable passage structure acts as an intermediary between the generator and the external environment. It facilitates heat transfer from the generator to the surrounding air without interfering with the generator's electrical energy conversion process, thus solving the overheating problem while preserving energy recovery functionality
2Reliability
If the cover mechanism is made solid to protect internal components, then protection capability is improved, but heat dissipation deteriorates
Solution Approach 1:
The cover mechanism employs an air permeable passage structure that provides protective enclosure while maintaining porosity for air flow. This allows the cover to protect internal components from external contaminants while simultaneously enabling heat dissipation through the permeable structure
Solution Approach 2:
The cover mechanism is segmented into multiple regions including the air permeable passage structure. This segmentation allows different portions of the cover to serve different functions: some areas provide protection while others facilitate heat dissipation, resolving the contradiction between protection capability and heat dissipation
