Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If multiple case members are used to cover the display panel and electronic components, then the heat dissipation effectiveness is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The patent combines multiple case members (inner plate, module cover, back cover) into a single integrated module cover structure. This unified structure performs multiple functions: covering the display panel, accommodating electronic components, and providing heat dissipation pathways, thereby reducing the number of separate components while maintaining heat dissipation effectiveness.
Solution Approach 2:
The module cover is designed as a multi-functional component that simultaneously serves as a protective cover, an accommodation structure for electronic components, and a heat dissipation system. The integration of vent holes and extension portions into the module cover enables it to perform thermal management functions without requiring additional dedicated components.
2Temperature
If multiple case members are used to cover the display panel and electronic components, then the heat dissipation effectiveness is improved, but the manufacturing cost increases
Solution Approach 1:
By merging multiple case members into a single module cover, the patent reduces the number of manufacturing steps, assembly operations, and associated costs. The integrated structure can be manufactured as a single piece or pre-assembled unit, simplifying the production process and reducing overall manufacturing cost while maintaining heat dissipation functionality.
3Temperature
If a complex assembly process is used to assemble multiple case members, then the heat dissipation structure is effective, but the assembly time and manufacturing cost increase
Solution Approach 1:
The integration of multiple case members into a single module cover eliminates the need for multiple assembly steps involving separate components. The unified structure reduces assembly time by allowing the display panel, electronic components, and heat dissipation pathways to be assembled together in fewer operations.
4Device complexity
If heat is not effectively dissipated from the panel and circuit components, then the manufacturing process is simpler, but panel defects and deformation occur
Solution Approach 1:
The patent converts the harmful heat generated by the display panel and electronic components into a manageable thermal flow by designing specific heat dissipation pathways. The vent holes and extension portions guide the heat flow from the panel and components through the module cover to the external environment, transforming the harmful thermal energy into a controlled dissipation process that prevents panel defects and deformation.
