Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If heat dissipation structures and waterproofing structures are added to support advanced functions, then heat dissipation capability and reliability are improved, but device thickness increases
Solution Approach 1:
The patent merges the heat dissipation function and waterproofing function into a single integrated structure. The waterproofing structure includes a heat dissipation member that is in direct thermal contact with the OLED display module, allowing heat to be conducted away while the same structure provides waterproofing. This eliminates the need for separate heat dissipation and waterproofing layers, thereby maintaining compact thickness while achieving both functions simultaneously.
Solution Approach 2:
The waterproofing structure is designed to serve multiple functions: it provides waterproofing protection, acts as a heat dissipation pathway, and maintains structural integrity. The heat dissipation member integrated into the waterproofing structure can conduct heat from the OLED display module while the waterproofing structure prevents moisture ingress, demonstrating multi-functionality that resolves the thickness contradiction.
2Adaptability or versatility
If multiple functional layers are added for touch sensing and heat dissipation, then functionality is improved, but structural simplicity is reduced
Solution Approach 1:
The patent combines the touch sensing function and heat dissipation function into an integrated structure. The waterproofing structure includes a heat dissipation member that is in direct thermal contact with the OLED display module, allowing heat to be conducted away while the same structure provides waterproofing. This eliminates the need for separate heat dissipation and waterproofing layers, thereby maintaining compact thickness while achieving both functions simultaneously.
