Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mechanical fastening with sealing pads is used to seal air vent holes, then waterproofing test reliability is improved, but device complexity increases
Solution Approach 1:
The waterproofing test device is divided into separate functional modules: clip devices for mechanical fastening, sealing pads for sealing air vent holes, and a main body for pressure control. This segmentation allows each component to perform its specific function independently, improving reliability while keeping the overall system manageable in complexity
Solution Approach 2:
The sealing pad acts as an intermediary element between the clip device and the air vent hole. It provides a reliable seal without requiring direct mechanical contact between the clip and the vent hole, thereby improving sealing reliability while simplifying the mechanical structure
2Reliability
If pressure change is applied to inject or suction air through air vent holes, then waterproofing performance is improved, but harmful factors to the electronic device increase
Solution Approach 1:
The system controls and changes pressure parameters dynamically during the waterproofing test. By applying controlled pressure changes through the sealing pad and connection hose, the system can simulate water pressure conditions without creating harmful pressure spikes, thereby improving test accuracy while minimizing damage risk to the electronic device
Solution Approach 2:
The sealing pad provides a cushioning interface between the pressure application point and the air vent hole. This cushioning mechanism distributes the pressure change gradually, preventing sudden pressure shocks that could damage the electronic device while still effectively testing waterproofing performance
