Embedded Handle Rod for Battery Pack Transportation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Battery packs lack a convenient and space-efficient means for transportation due to protruding handles that interfere with other objects and require complex locking mechanisms for top cover attachment and detachment.
Innovation Solution
A battery pack design incorporating a handle rod embedded within the case, with a grip groove and a top cover featuring a hook protrusion that allows easy attachment and detachment without additional locking members, enhancing mobility and space efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a protruding handle is provided on the battery pack, then it is easy to transport, but it interferes with other objects and reduces space efficiency
Solution Approach 1:
The handle rod is embedded inside the battery pack case, with only a portion exposed for gripping. This nesting approach allows the handle to be stored within the case body when not in use, eliminating interference with other objects while maintaining transportation convenience when needed.
Solution Approach 2:
The handle rod can be rotated between a horizontal position (protruding for gripping) and a vertical position (retracted inside the case). This dynamic reconfiguration allows the handle to adapt between transportation mode and storage mode, resolving the contradiction between ease of operation and space efficiency.
2Reliability
If a complex locking mechanism is used to attach the top cover, then the cover is securely fixed, but the attachment and detachment process becomes complicated
Solution Approach 1:
The hook protrusion on the top cover automatically engages with the handle rod to secure the cover in place, and can be easily detached by simple manual manipulation. This self-service mechanism eliminates the need for complex locking systems while maintaining secure fixation during normal operation.
Solution Approach 2:
The complex locking mechanism is completely removed and replaced with a simple hook-shaped protrusion that provides sufficient securing function. This extraction of unnecessary complexity simplifies the overall structure while maintaining the essential function of secure cover attachment.
