Terminal Connector Fixing for Easy Battery Pack Disassembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional energy storage apparatuses are difficult to disassemble due to the complexity of removing multiple small metal screws, which complicates maintenance and repair.
Innovation Solution
The energy storage apparatus includes a terminal member, a connector for electrical input and output, and a plurality of linking parts, with at least one linking part made of resin that can be easily broken or cut, allowing for simple disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If multiple small metal screws are used to fix the terminal block, then the fixing strength is improved, but the ease of disassembly deteriorates
Solution Approach 1:
The fixing members are segmented into two distinct types: metal screws for strong fixation and resin members for easy breaking. This segmentation allows each type to serve its specific function - metal screws provide the necessary fixing strength while resin members enable simple disassembly by breaking, thus resolving the contradiction between strong fixation and easy disassembly
Solution Approach 2:
Different materials are assigned to different locations based on functional requirements. Metal screws are used where high strength is needed for secure attachment, while resin members are used where ease of removal is prioritized. This local differentiation of material properties allows the system to simultaneously achieve strong fixation and easy disassembly
2Reliability
If multiple small metal screws are used to fix the terminal block, then the reliability of connection is improved, but the device complexity increases
Solution Approach 1:
The connection fixing system is divided into two functional segments: metal screws that ensure reliable electrical connection and resin members that simplify the disassembly process. This segmentation reduces disassembly complexity from requiring multiple screw removals to simply breaking resin members, while maintaining connection reliability through the metal screw components
Solution Approach 2:
The resin members function as disposable or easily replaceable components that can be broken without special tools or procedures. This approach reduces the complexity of disassembly operations while maintaining the overall reliability of the connection through the more durable metal screw components
