Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery packs face challenges in installation compatibility and workability due to varying electrical connection types, requiring additional components and increasing installation complexity.
Innovation Solution
A battery pack design featuring a connection guide unit with multiple connection guider types on different sides of the pack case, allowing for easy access and rotation to accommodate various electrical connections, including a shaft portion and slider for selective exposure of connection guiders, enhancing compatibility with different inverter types.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional battery pack uses a single connection type, then the device complexity is reduced, but the adaptability to different electrical members decreases
Solution Approach 1:
The connection guide unit employs a rotatable shaft portion that can dynamically change its orientation to expose different connection guiders (first connection guider for US type, second connection guider for EU type). This dynamic adjustment allows a single battery pack to adapt to different electrical connection types without requiring multiple fixed connection structures, thereby resolving the contradiction between adaptability and device complexity.
2Adaptability or versatility
If additional dedicated parts are added for different connection types, then the adaptability increases, but the device complexity and installation workability worsen
Solution Approach 1:
The connection guide unit is designed as a universal component that integrates multiple connection guiders (first connection guider and second connection guider) into a single structure. By rotating the shaft portion, the same connection guide unit can serve different connection types (US and EU standards), eliminating the need for multiple dedicated parts and simplifying the installation process while maintaining broad compatibility.
3Adaptability or versatility
If multiple connection guiders are provided on different sides, then the adaptability improves, but the ease of operation decreases due to rotation requirement
Solution Approach 1:
The connection guide unit is pre-configured with multiple connection guiders positioned on different sides of the pack case, and the shaft portion can be pre-rotated to the appropriate orientation before connection. This preliminary preparation ensures that the correct connection guider is already exposed and accessible when installation begins, reducing the operational complexity despite the multi-functional design.
