Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If air circulation is used for heat dissipation, then the structure is simple, but the thermal conductivity is low causing cell overheating
Solution Approach 1:
The patent introduces a heat dissipating means as an intermediary component between the cells and the external environment. This heat dissipating means comprises spacer components made of materials with higher thermal conductivity than air, acting as a thermal bridge to facilitate heat transfer from the cells to the surrounding environment, thereby resolving the contradiction between structural simplicity and effective heat dissipation.
Solution Approach 2:
The heat dissipating means utilizes composite material construction, combining spacer components made of materials with higher thermal conductivity than air (such as metals or thermally conductive polymers) with the existing retaining components. This composite approach enhances the overall thermal conductivity of the heat dissipation system while maintaining structural integrity and simplicity.
2Device complexity
If retaining components with low thermal conductivity are used, then the structure is simple, but heat dissipation efficiency is poor
Solution Approach 1:
The heat dissipating means is segmented into multiple independent spacer components rather than using a single monolithic retaining component. Each spacer component can be independently positioned and optimized for thermal contact with adjacent cells, allowing the system to achieve high heat dissipation efficiency through distributed thermal pathways while maintaining relatively simple component structures.
3Ease of manufacture
If gaps are left between adjacent cells, then the assembly is easy to manufacture, but heat dissipation is insufficient
Solution Approach 1:
The spacer components act as intermediary elements that bridge the gaps between adjacent cells. These spacers are positioned in the gaps and make thermal contact with the outer walls of the cells, converting the previously harmful gaps into beneficial thermal pathways. This approach maintains the ease of assembly while significantly improving heat dissipation effectiveness.
