Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a simple protective structure is used, then manufacturing cost is reduced, but protection against water, oxygen, and external impacts is insufficient
Solution Approach 1:
The patent employs a multi-layer composite structure consisting of an adhesive layer, heat dissipation member, and reflective layer. Each layer serves specific functions: the adhesive layer provides bonding and basic protection, the heat dissipation member with metal layers and partition walls offers thermal management and structural reinforcement, and the reflective layer prevents water and oxygen ingress. This composite approach achieves comprehensive protection while maintaining manufacturing feasibility through standardized layer assembly.
Solution Approach 2:
The protective structure is divided into distinct functional layers: an adhesive layer for bonding, a heat dissipation member with first and second metal layers for thermal management, and a reflective layer for barrier protection. The heat dissipation member itself is segmented into multiple metal layers separated by partition walls, creating a modular structure that provides both mechanical strength and thermal pathways while preventing moisture penetration through the segmented design.
2Temperature
If a multi-layer heat dissipation member is used, then heat dissipation performance is improved, but device complexity increases
Solution Approach 1:
The heat dissipation member is designed to perform multiple functions simultaneously: the first and second metal layers with intermediate partition walls provide thermal conduction pathways for efficient heat dissipation, while the same layered structure creates physical barriers against water and oxygen penetration. The partition walls serve dual purposes of thermal management and structural reinforcement, eliminating the need for separate barrier layers and reducing overall device complexity despite the multi-layer construction.
