Protective Battery Bracket Structure for Dual-Battery Power Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power tools with rechargeable batteries are inadequately protected from mechanical impacts, leading to potential damage and fault-prone behavior.
Innovation Solution
A power tool design featuring a protective apparatus with a modular construction, including frame elements and bearing surfaces, that securely holds and protects two rechargeable batteries, ensuring they are not directly impacted in case of drops by dissipating energy through the protective apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If protective apparatus is added to protect rechargeable batteries from impacts, then battery protection from mechanical effects is improved, but device complexity increases
Solution Approach 1:
The protective apparatus is divided into a housing component and a bracket component that can be assembled together. The housing contains recesses that receive the batteries, while the bracket provides additional protection and mounting features. This segmentation allows for easier manufacturing, assembly, and maintenance while providing comprehensive protection for the batteries.
2Quantity of substance
If protective apparatus with sufficient length is designed to hold two batteries, then battery holding capacity is improved, but device length and bulk increase
Solution Approach 1:
The bracket is positioned within the housing structure, with the battery-receiving recesses nested within the overall protective apparatus. This nested arrangement allows the protective apparatus to accommodate two batteries of significant capacity while minimizing the external dimensions and bulk of the protective structure.
3Ease of operation
If bearing surfaces are added for safe setting down, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The housing structure serves multiple functions: it provides the protective enclosure for the batteries, structural support for the overall apparatus, and incorporates bearing surfaces on its exterior that can serve as stable contact points for safe setting down during handling and operation. This multi-functionality eliminates the need for separate dedicated bearing surface components.

AI summary
A power tool, in particular a chipping hammer, containing a first and second side handle and a tool housing having an interface for releasably receiving and holding a first and second rechargeable battery, wherein a side-handle axis extending through the first and second side handles is arranged substantially perpendicularly to a working axis extending through the tool housing. The power tool contains a protective apparatus for protecting the first and second rechargeable batteries, the protective apparatus having an internal volume for at least partially receiving the first and second rechargeable batteries.
