Replaceable Battery Handle Layout for Connector Clearance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing replaceable batteries for vehicles face challenges in providing a grip-handle that does not interfere with the connector connection, necessitating design restrictions that complicate storage and handling.
Innovation Solution
A replaceable battery design featuring a rotatable grip-handle on the upper surface of the case, allowing for easy carrying without interrupting connector connections, combined with a thicker second lid part for improved rigidity and reduced weight.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a grip-handle is provided in the lid part with connector, then the battery can be carried conveniently, but the connector connection is interrupted
Solution Approach 1:
The grip-handle is moved from the vertical surface of the lid part to the horizontal upper surface of the main body part, changing its spatial dimension. This allows the handle to be positioned away from the connector area while remaining accessible for carrying operations.
Solution Approach 2:
The grip-handle is designed to be rotatable around a shaft extending along the upper edge of the second lid part. This dynamic positioning allows the handle to rotate out of the way when not in use, preventing interference with connector connection while maintaining carrying functionality.
2Ease of operation
If the grip-handle protrudes upward, then the battery can be carried easily, but the battery cannot be accommodated in the storage space
Solution Approach 1:
The grip-handle is repositioned from a vertical protrusion to a horizontal placement on the upper surface, utilizing the horizontal dimension instead of vertical space. This eliminates the need for increased storage volume while maintaining carrying functionality.
Solution Approach 2:
The rotatable design allows the grip-handle to be positioned flat on the upper surface during storage, minimizing the battery's overall height and ensuring compatibility with existing storage spaces.
3Ease of operation
If the grip-handle is placed on the upper surface and made rotatable, then carrying is enabled without blocking connector, but the structure becomes more complex
Solution Approach 1:
A rotatable joint mechanism is introduced to allow the grip-handle to rotate around a shaft extending along the upper edge of the second lid part. This simple rotational degree of freedom enables the handle to move between carrying position and storage position without complex actuation systems.
Solution Approach 2:
The grip-handle structure is integrated with the second lid part through the rotatable connection, combining two functional elements (handle and lid) into a unified assembly that shares common structural support and mounting features.
