Water-Resistant Vent Assembly for High-Pressure Film Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices are prone to water leakage in high water pressure scenarios, such as swimming or diving, due to the damage of water-resistant and breathable films, which compromises their reliability and functionality.
Innovation Solution
A water-resistant assembly is designed for electronic devices, comprising a switch, clamping bar, sealing member, and elastic member. This assembly is mounted to the housing of the electronic device, with the switch capable of moving to block or unblock the housing through hole, ensuring the sealing member can effectively prevent water ingress even under high pressure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a water-resistant and breathable film is provided on the through hole, then the device can breathe and resist water in daily use, but the film is prone to damage in high water pressure scenarios leading to water leakage
Solution Approach 1:
The patent employs a dynamic sealing mechanism where a movable closure component can shift between open and closed positions. The closure is driven by an elastic member (spring) that provides restoring force, allowing the system to adapt to different pressure conditions. In high water pressure scenarios, the closure moves to block the through hole, protecting the vulnerable film from damage while maintaining water resistance.
Solution Approach 2:
The patent introduces a closure component as an intermediary element between the external high-pressure water environment and the internal device space. This closure acts as a protective mediator that can be positioned to seal the through hole, preventing direct exposure of the water-resistant film to high pressure water, thereby avoiding film damage while maintaining breathability during normal use.
2Reliability
If the housing through hole is blocked to prevent water ingress, then water-resistant performance improves, but air pressure balancing and breathability functions are compromised
Solution Approach 1:
The patent uses a dynamic closure mechanism that can transition between open and closed states. During normal operation, the closure remains open allowing air pressure balancing and breathability. When high water pressure is detected or anticipated, the closure moves to block the through hole, providing water protection. The elastic member ensures the closure can respond dynamically to pressure changes, maintaining both breathability and water resistance as needed.
Solution Approach 2:
The closure mechanism operates periodically or intermittently based on environmental conditions. It remains open during normal use to allow air exchange and pressure balancing, then closes when water pressure threatens the film. This periodic switching between open and closed states allows the system to maintain both breathability and water-resistant performance at different times, resolving the contradiction between these two functions.

Function Achieved in This Case
The water-resistant assembly effectively prevents water leakage in high water pressure environments, ensuring the electronic device remains operational and reliable, as the water-resistant and breathable film is protected from high pressure and thus less likely to be damaged.

AI summary
A water-resistant assembly is provided which, is mounted to a housing of an electronic device. A switch in the water-resistant assembly can move under an external force, so that an inner cavity of the electronic device is connected to or disconnected from outside. The electronic device includes a housing, a water-resistant and breathable film, and the water-resistant assembly. The housing encloses a housing space, the housing has a housing through hole, and one end of the housing through hole is connected to the housing space through the water-resistant and breathable film. The water-resistant assembly is located at one end that is of the housing through hole and that is far away from the water-resistant and breathable film. According to the application, the electronic device is enabled to operate reliably in both a daily scenario and a high water pressure scenario.
