Transparent Seal Member Integrating Light Source for Hermetic Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional sealing structures for electronic equipment, such as cellular phones, complicate the design and increase the size of the device by requiring separate structures for illumination and sealing, making it difficult to achieve hermetic sealing and design differentiation.
Innovation Solution
A sealing structure that integrates a transparent or translucent seal member with a light source element on a substrate board, allowing the seal member to emit light and provide hermetic sealing while enhancing design and differentiation with a simple construction, using a flexible wiring board and reflective parts to guide light effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a separate illumination structure is added to the sealing structure, then design differentiation and illumination function are improved, but device complexity and size increase
Solution Approach 1:
The patent combines the sealing member and illumination structure into a single integrated component. The sealing member itself is configured to include light guide portions that direct light from the light source element, eliminating the need for separate illumination structures and reducing overall device complexity while maintaining both sealing and illumination functions
Solution Approach 2:
The sealing member is designed to perform multiple functions simultaneously: it provides hermetic sealing between housing parts and acts as an illumination device by incorporating light guide portions. This multi-functional design allows the same component to achieve both sealing reliability and design differentiation without adding extra parts
2Reliability
If adhesive is used to fill gaps between housings for sealing, then sealing function is achieved, but reassembly becomes difficult after disassembly
Solution Approach 1:
The sealing structure is designed as a separable mechanical connection rather than a permanent adhesive bond. The sealing member can be removed and reinstalled, allowing the housing parts to be disassembled and reassembled multiple times while maintaining sealing reliability through the mechanical sealing interface
Solution Approach 2:
Instead of using adhesive to create a permanent seal that prevents disassembly, the patent uses a mechanical sealing structure that is designed to be easily assembled and disassembled. The sealing function is achieved through the mechanical interface of the sealing member rather than through chemical bonding, inverting the conventional approach

Function Achieved in This Case
The solution enables reliable hermetic sealing and design enhancement with reduced complexity and size, improving waterproof performance and allowing for easy reassembly during maintenance.
Implementation Method 1
a light source element that is arranged on said substrate board; wherein said seal member is transparent or translucent, and it is constructed such that said light source element is arranged in a region of hermetic sealing formed by said seal member, whereby at least a part of said seal member emits light by the light radiated from said light source element
Implementation Method 2
have a reflective part which is able to reflect the light incident to the interior of said seal member from said light source element thereby to change the direction of movement thereof along the shape of said seal member
