Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If a through-hole is formed at the second end of the body to provide air passage, then air pressure difference is improved, but waterproof performance deteriorates
Solution Approach 1:
A membrane is introduced as an intermediary component covering the through-hole. The membrane allows air to pass through while blocking water, serving as a mediator that resolves the contradiction between maintaining air pressure difference and preventing water ingress.
Solution Approach 2:
The membrane functions as a thin film structure that selectively permits gas transmission while preventing liquid penetration. This flexible barrier maintains the through-hole's air passage function while adding waterproof protection.
2Reliability
If the device structure is enhanced to improve durability, then reliability is improved, but device complexity increases
Solution Approach 1:
The device is divided into distinct segments including a body, a separate membrane component, a base, and a cover. This segmentation allows each component to be optimized independently for its specific function while contributing to overall durability through modular construction.
Solution Approach 2:
The device employs composite construction by combining different materials and components - the membrane material differs from the body material, and the base and cover provide additional protective layers. This composite approach enhances durability through material diversity and functional specialization.
