Timepiece Case Structure for Waterproof Exterior Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional techniques face challenges in combining an exterior member with a timepiece case while ensuring a waterproof property, leading to increased size and thickness.
Innovation Solution
A timepiece case design incorporating a windshield member with a waterproofing member between the case and the windshield, and an exterior member facing a distinct side surface portion of the windshield, utilizing adhesives for sealing and support protrusions to maintain compactness and waterproofing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If an exterior member is combined with a timepiece case while ensuring a waterproof property, then the waterproof property is improved, but the size and thickness of the electronic timepiece increase
Solution Approach 1:
The exterior member is positioned to face a side surface portion of the windshield member rather than being integrated into the case structure. This dimensional repositioning allows the exterior member to be attached in a different spatial dimension, reducing the need to increase case thickness while maintaining waterproof integrity through the windshield member's sealing surface.
Solution Approach 2:
The windshield member serves as an intermediary element between the case and the exterior member. It provides a sealing surface that allows the exterior member to be attached without directly increasing the case thickness, thereby maintaining the waterproof property while achieving compact integration.
2Reliability
If an exterior member is combined with a timepiece case while ensuring a waterproof property, then the waterproof property is improved, but the size of the electronic timepiece increases
Solution Approach 1:
By positioning the exterior member to face a side surface portion of the windshield member rather than integrating it into the case, the design utilizes different spatial dimensions for attachment. This reduces the overall volume required for the timepiece while maintaining waterproof integrity.
Solution Approach 2:
The exterior member is merged with the windshield member assembly rather than being separately integrated into the case. This combining approach allows the exterior member to be attached to the existing windshield structure, reducing the need to increase the overall timepiece size.
