Expandable Battery Cover for Power Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional battery covers for power tools lack the ability to accommodate varying battery sizes efficiently and provide adequate protection while allowing easy access or sealing against debris and liquids.
Innovation Solution
A battery cover with an expandable portion that moves from a collapsed to an expanded position, featuring a panel and angled portions made of flexible materials like silicone or rubber, which increases the internal cavity area to accommodate larger batteries and provides sealing capabilities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If a rigid battery cover is used to protect the battery, then protection against debris and liquid is improved, but the ability to accommodate varying battery sizes is reduced
Solution Approach 1:
The battery cover incorporates an expandable portion with angled portions that can move between extended and retracted positions, allowing the cover to dynamically adjust its internal volume. This dynamic structure enables the same cover to accommodate different battery sizes while maintaining protection when closed
Solution Approach 2:
The expandable portion changes the physical parameters of the battery cover by altering its internal volume and shape. When the angled portions are extended, the internal volume increases to accommodate larger batteries; when retracted, the volume decreases for compact storage or smaller batteries
2Adaptability or versatility
If the battery cover is designed to accommodate larger batteries, then adaptability is improved, but the internal cavity area increases reducing compactness
Solution Approach 1:
The expandable portion transforms the static battery cover into a dynamic structure that only increases its volume when needed. The angled portions can be extended to accommodate larger batteries and retracted when smaller batteries are used, maintaining compactness otherwise
3Device complexity
If a fixed battery cover structure is used, then device complexity is reduced, but the ability to provide both protection and access is limited
Solution Approach 1:
The battery cover is segmented into a fixed portion and an expandable portion with movable angled sections. This segmentation allows the cover to transition between protected and accessible states while maintaining relatively simple construction

AI summary
A battery cover and a power tool with a battery cover. The power tool includes a housing arranged to be coupled with a battery, and a battery cover which covers at least a portion of the battery when the battery is coupled to the housing. The battery cover includes an expandable portion moveable from a collapsed position to an expanded position. When the expandable portion is in the collapsed position, the battery cover has a first internal area. When the expandable portion is in the expanded position the battery cover has a second internal area. The first internal area is less than the second internal area.
