Recessed Battery Pack Locking Structure for Compact Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery packs are inconvenient to hold and carry due to their irregular shape and protruding locking portions, which hinder comfortable use and portability.
Innovation Solution
A battery pack design featuring a compact, smooth, and flat shape with recessed sliding slots and locking portions, allowing for a reduced height and improved ergonomics, along with a housing that accommodates cells and includes a sliding slot and locking mechanism for secure engagement with external devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the locking portion protrudes out of the top plane, then the locking mechanism can be easily accessed and operated, but the battery pack becomes irregularly shaped and uncomfortable to hold
Solution Approach 1:
The locking portion is nested within a recess on the top surface of the battery pack rather than protruding outward. This allows the locking mechanism to be contained within the battery pack's outer dimensions, maintaining a regular shape while still providing functional access to the locking portion through the recess opening.
2Ease of operation
If the sliding slot is directly exposed to the outside, then the mechanical connection with external device can be easily achieved, but the battery pack becomes irregularly shaped and inconvenient to carry
Solution Approach 1:
The sliding slot is nested within a recess on the top surface of the battery pack. This configuration allows the sliding slot to be accessible for mechanical connection with external devices while being contained within the battery pack's recessed area, preventing it from protruding and disrupting the regular external shape of the battery pack.
3Adaptability or versatility
If the locking portion and sliding slot are on the top plane, then the engagement with external device can be achieved, but the height of the battery pack increases
Solution Approach 1:
Instead of placing the locking portion and sliding slot on the top plane (horizontal dimension), the design moves them into a recess that extends downward from the top plane (vertical dimension). This dimensional transition allows the engagement features to be positioned lower, reducing the overall height of the battery pack while maintaining engagement capability.
