Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a thermally insulating element is added to prevent outer surface overheating, then user safety is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The patent applies porous materials by incorporating a plurality of perforations in the device housing to enable heat dissipation from the interior space. These perforations allow thermal energy to escape through controlled porous pathways, preventing interior overheating while avoiding the need for additional insulating components that would increase device complexity.
Solution Approach 2:
The patent extracts the heat dissipation function directly into the device housing structure by integrating perforations into the housing itself. This eliminates the need for separate thermally insulating elements, thereby reducing device complexity and manufacturing cost while still addressing thermal management requirements.
2Object-affected harmful factors
If a thermally insulating element is added to prevent outer surface overheating, then user safety is improved, but manufacturing cost increases
Solution Approach 1:
The patent merges the heat dissipation function with the device housing by integrating perforations directly into the housing structure. This consolidation eliminates the need for separate insulating components, reducing the number of parts to manufacture and assemble, thereby lowering manufacturing cost while maintaining thermal management effectiveness.
Solution Approach 2:
The device housing serves multiple functions: it provides structural support, contains internal components, and simultaneously acts as a heat dissipation structure through integrated perforations. This multi-functionality reduces the need for additional dedicated thermal management components, simplifying manufacturing and reducing costs.
3Object-affected harmful factors
If thermally insulating material is used to reduce heat transfer to outer surface, then outer surface temperature is reduced, but interior space temperature increases
Solution Approach 1:
The patent segments the thermal management approach by providing separate heat dissipation pathways: the thermally insulating element manages heat transfer to the outer surface, while the perforations in the device housing manage heat dissipation from the interior space. This segmentation allows independent control of thermal conditions in different zones, preventing interior overheating while maintaining safe outer surface temperatures.
Solution Approach 2:
The perforations act as intermediary structures that facilitate heat dissipation from the interior space to the external environment. By introducing these intermediate heat escape pathways, the system balances thermal insulation (to protect the outer surface) with thermal ventilation (to cool the interior space), resolving the thermal contradiction.
