Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In electronic devices with waterproof structures, the hermetically sealed internal space can lead to pressure and temperature issues that damage sound components, preventing smooth operation and exposing the device to risk during outdoor or water-based activities.
Innovation Solution
Incorporating an air vent hole that interconnects the internal and external spaces, either through a pre-existing opening or a concealed air-permeable waterproof film, to stabilize the operating environment of sound components while maintaining waterproof performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the internal space of the electronic device is hermetically sealed to improve waterproof performance, then waterproof performance is improved, but the operating environment of sound components becomes unstable due to pressure and temperature changes
Solution Approach 1:
The patent employs an air-permeable waterproof film that acts as a flexible barrier, allowing pressure equalization while blocking moisture. This thin film structure enables the device to maintain waterproof integrity while permitting air molecules to pass through, thereby stabilizing the internal environment for sound components during outdoor or water-based activities.
2Reliability
If the internal space is sealed to prevent moisture contamination, then waterproof performance is improved, but sound components cannot operate smoothly due to pressure buildup
Solution Approach 1:
The patent utilizes an air-permeable waterproof film with porous structure that selectively allows air molecules to pass through while blocking larger moisture molecules. This porous material enables pressure equalization between internal and external spaces, ensuring sound components can operate smoothly even when the device is used in water or humid environments.
3Reliability
If the internal space is hermetically sealed, then waterproof performance is improved, but pressure increase due to external force or temperature change can damage sound components
Solution Approach 1:
The patent extracts the pressure equalization function from the sealed structure by incorporating an air vent hole through the waterproof film. This extracted function allows excess pressure to be released externally while the film itself maintains the waterproof seal, thereby protecting sound components from pressure damage during impacts or temperature changes.
Solution Approach 2:
The air-permeable waterproof film provides beforehand cushioning by allowing gradual pressure equalization before external forces or temperature changes can cause damaging pressure buildup. The film's permeability enables the internal space to adapt to external pressure changes, cushioning the sound components from sudden pressure shocks.
