Key Assembly Waterproof Bracket for Slim Electronic Housings
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in maintaining waterproof and dustproof features, especially in mechanical operating structures like key assemblies, which can be damaged during assembly or repair processes.
Innovation Solution
The electronic device incorporates a key assembly design that includes a waterproof bracket with a protrusion featuring a hook, and a cover member with a hanging hole, allowing for a waterproof function to be applied without requiring additional space, thus maintaining the device's slimness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mechanical operating structure is used for the key assembly, then the key can be operated mechanically, but the waterproofing structure is exposed to damage risk during assembly or repair processes
Solution Approach 1:
The key assembly is divided into separate components: a cover member that can be detached from the waterproof bracket. This segmentation allows the waterproof bracket to remain intact and protected during assembly or repair, while the cover member can be independently handled for mechanical operation needs.
Solution Approach 2:
The waterproof bracket acts as an intermediary structure that provides both waterproofing protection and mechanical support. The hook structure on the bracket mediates between the cover member and the underlying components, allowing mechanical operation while maintaining waterproof integrity through the bracket's protective position.
2Reliability
If additional waterproofing structures are added to protect the key assembly, then waterproof reliability is improved, but the device thickness increases
Solution Approach 1:
The waterproof bracket combines multiple functions into a single structure: it provides waterproofing protection, serves as a mechanical support structure, and includes the hook structure for securing the cover member. This merging eliminates the need for separate waterproofing layers or additional structural components that would increase device thickness.
Solution Approach 2:
The waterproof bracket is designed as a multi-functional component that simultaneously performs waterproofing, structural support, and mechanical coupling functions. The plate portion provides waterproof protection while the protrusion with hook provides mechanical attachment, making the single structure serve multiple purposes without adding extra thickness.
