Sealing System for Electronic Device Cover Gaps
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices, such as portable terminals, are vulnerable to moisture ingress due to gaps between the body and cover, which can damage internal components like batteries and electronic modules, especially when these devices integrate features like NFC antennas and solar charging modules.
Innovation Solution
The implementation of a sealing system that includes a first sealing member between the body and cover, and an auxiliary coupling unit along the circumference of the cover assembly, to prevent moisture introduction by sealing gaps between the body and cover, and between the inner and outer covers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a battery cover is engaged with the body to cover the battery space, then the battery is protected, but gaps are generated between the battery cover and body that allow moisture ingress
Solution Approach 1:
A sealing member is introduced as an intermediary element between the battery cover and the body. This sealing member fills and seals the gap that naturally exists between these two components, preventing moisture from penetrating into the battery space while maintaining the protective function of the battery cover.
Solution Approach 2:
The sealing member is implemented as a flexible sealing structure that can adapt to the gap between the battery cover and body. This flexible sealing film effectively blocks the moisture ingress path created by the engagement gap, protecting internal components while maintaining the detachable cover design.
2Adaptability or versatility
If electronic components are mounted to the inner surface of the battery cover, then functionality is enhanced, but moisture introduction through gaps damages these electronic components
Solution Approach 1:
The sealing member serves as a protective intermediary between the external environment and the electronic components mounted on the battery cover's inner surface. By sealing the gap at the interface between the battery cover and body, it creates a protective barrier that shields moisture-sensitive electronic components while allowing their integration into the cover structure.
3Reliability
If the display unit is covered by a flip type case, then the display is protected, but gaps are generated that create water submersion paths
Solution Approach 1:
The sealing member acts as a flexible sealing film that fills the gap created by the flip type case engagement. This sealing structure maintains the protective enclosure for the display unit while blocking water submersion paths that would otherwise penetrate through the engagement gap between the case and the device body.

AI summary
An electronic device is provided. The electronic device includes a body configured to house the electronic device and including a space for accommodating a battery on one surface of the body and a cover configured to cover at least the space and being detachably attached to the body. The cover includes a first sealing member located between the one surface of the body and an inner surface of the cover and formed to surround the space.
