Wearable Device Rod with Tool-Free Battery Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing smart glasses require cumbersome battery replacement processes due to the use of fixable doors and connection means like screws, glue, or adhesives, necessitating tools for extraction.
Innovation Solution
A rod for devices, such as smart glasses, featuring a locking system with an extraction aid element that switches between closing and opening configurations, facilitating easy installation and removal of electronic components like batteries without tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If closing doors are used to retain the battery in the seat, then the battery is protected from shocks and external agents, but the battery replacement process becomes cumbersome and requires tools
Solution Approach 1:
The closing door is divided into a fixed portion and a movable portion that can slide relative to each other. The movable portion can be easily pushed to open the door for battery replacement, while the fixed portion remains secured to the rod. This segmentation allows the door to provide protection when closed while enabling tool-free opening when needed.
Solution Approach 2:
The closing door transitions from a static, fixed structure to a dynamic structure where the movable portion can slide along the rod. This dynamic capability allows the door to switch between a closed protective state and an open accessible state, resolving the contradiction between protection and ease of replacement.
2Reliability
If fixable doors with screws or adhesives are used, then the battery is securely retained, but the replacement process becomes complex and time-consuming
Solution Approach 1:
The door assembly is segmented into fixed and movable portions that can be easily separated. The movable portion can be quickly pushed open without requiring screwdrivers or solvents, dramatically reducing replacement time while the fixed portion maintains secure retention when closed.
Solution Approach 2:
The movable portion of the door is designed to be manually operable by the user without requiring external tools. The user can simply push the movable portion to open the door and replace the battery, making the system self-servicing and eliminating the time loss associated with tool-based fastening methods.
3Ease of operation
If the rod structure is simplified for easy battery access, then replacement becomes easier, but the protection against shocks and external agents may be compromised
Solution Approach 1:
The rod structure is segmented to include both a fixed portion that maintains structural integrity and protection capabilities, and a movable portion that enables easy access. This segmentation allows the rod to provide robust protection when closed while facilitating tool-free opening for battery replacement.
Solution Approach 2:
Different portions of the rod structure have different functional qualities: the fixed portion provides structural strength and protection, while the movable portion provides accessibility. This local differentiation of qualities allows the overall structure to simultaneously achieve both protection and ease of access.
