Rotatable Eyewear Rod for Tool-Free Battery Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart eyewear designs require cumbersome battery replacement processes due to the use of closure doors fixed with screws or adhesives, necessitating tools for extraction.
Innovation Solution
A rotatable rod system with integrated housing seats and extraction aids, allowing easy insertion and removal of electronic components like batteries without tools, facilitated by magnetic contacts and hinges for secure coupling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If closure doors are fixed to the rod by screws or adhesives, then the battery is protected from impacts and external agents, but the battery replacement process becomes cumbersome and requires tools
Solution Approach 1:
The rod is divided into two separable portions: a first portion with a first housing seat and a second portion with a second housing seat. These portions can be easily separated from each other to allow battery replacement without tools, while still providing protection when assembled together.
Solution Approach 2:
The second housing seat is nested within or adjacent to the first housing seat, creating a layered protective structure. The two housing seats work together to secure the battery while allowing easy access through simple separation of the rod portions.
2Reliability
If the rod structure is made complex with multiple fixed components, then the battery is securely retained, but the device complexity increases
Solution Approach 1:
The rod is segmented into two portions that can be easily assembled and disassembled. This segmentation simplifies the overall structure compared to using multiple fixed components like screws or adhesives, while still providing secure battery retention when the portions are assembled together.
Solution Approach 2:
The two housing seats (first and second) are combined to form a complete battery retention structure. When the two rod portions are assembled, their housing seats work together to securely hold the battery, achieving reliable retention with a simple two-part structure.
