Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a waterproof structure is additionally arranged in an electronic device to implement waterproof performance, then waterproof performance is improved, but device complexity and structural space increase
Solution Approach 1:
The patent combines multiple waterproofing functions into a single integrated waterproof structure that includes a waterproof layer, water absorbing layer, and liquid storing layer arranged in sequence. This merged structure prevents water from entering the electronic device while absorbing and storing water vapor, thereby improving waterproof performance without proportionally increasing structural complexity
Solution Approach 2:
The waterproof structure serves multiple functions simultaneously: the waterproof layer blocks liquid water, the water absorbing layer captures water vapor through capillary action, and the liquid storing layer accumulates absorbed water. This multi-functional design achieves comprehensive waterproof protection while optimizing space utilization within the electronic device
2Reliability
If traditional waterproof structures are used, then waterproof performance is achieved, but manufacturing difficulty and processing complexity increase
Solution Approach 1:
The patent employs thin film structures for the waterproof layer, water absorbing layer, and liquid storing layer. These flexible thin films can be easily manufactured using coating or lamination processes, reducing manufacturing difficulty while maintaining effective waterproof performance. The thin film design allows for simple integration into the electronic device structure
3Reliability
If water absorbing materials are used to prevent water ingress, then waterproof performance is improved, but the materials occupy excessive structural space
Solution Approach 1:
The patent implements a nested layer structure where the water absorbing layer and liquid storing layer are positioned between the waterproof layer and the electronic device components. This nested arrangement allows the water absorbing materials to be integrated within the existing device structure rather than adding external bulk, thereby reducing space occupation while maintaining waterproof effectiveness
