Electrochemical Device Tab Holders for Vibration Resistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electrochemical devices used in electrically powered tools are prone to vibration damage, leading to potential short circuits between the cathode and anode tabs, which compromises their vibration-resistance and stability.
Innovation Solution
The integration of tab holders made from heat-resistant resin on the outer surface of cathode and anode tabs, which are exposed outside the battery case, disperses external forces and immobilizes the tabs to prevent short circuits, enhancing vibration-resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cathode tab and anode tab are exposed to the outside of the battery case, then electrical connection is facilitated, but the tabs are vulnerable to vibration damage and short circuits
Solution Approach 1:
A tab holder is introduced as an intermediary component between the exposed tabs and the external environment. The tab holder receives and secures both the cathode tab and anode tab, providing mechanical protection while maintaining electrical connectivity. This mediator structure prevents direct exposure of tabs to vibration forces while preserving their electrical function.
Solution Approach 2:
The tab holder is formed from a resin material that provides a protective enclosure for the tabs. This shell-like structure absorbs and distributes external vibrational forces, protecting the internal tabs from direct mechanical damage while allowing the tabs to maintain their electrical connection functionality.
2Reliability
If tab holders are formed on the exposed tabs, then vibration-resistance is improved, but device complexity increases
Solution Approach 1:
The tab holder integrates multiple functions into a single component: it provides mechanical protection, secures the tabs in position, and maintains electrical connectivity. By combining these functions into one unified structure rather than using separate components for each function, the overall device complexity is minimized while achieving the desired vibration-resistance improvement.
