Removable Battery Pack Dual-Rail Interface for Tool Compatibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cordless electric tools with removable battery packs face compatibility issues due to manufacturer-specific interfaces, limiting the use of battery packs across different tool brands and requiring additional structural support for larger battery packs.
Innovation Solution
The introduction of a dual rail interface system, which includes both a primary and secondary set of rails and grooves, provides additional structural support and compatibility with both single and dual rail interface systems, allowing for the use of larger battery packs and increased flexibility across different tool brands.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single rail interface system is used for battery packs, then the device complexity is reduced, but the structural support for larger battery packs is insufficient
Solution Approach 1:
The interface system is segmented into two independent rail sets (first rail set and second rail set), each capable of providing structural support. This segmentation allows the battery pack interface to handle larger battery packs with improved structural support while maintaining relatively simple individual rail designs.
2Reliability
If manufacturer-specific interfaces are used, then the reliability of the tool-pack connection is improved, but the adaptability across different tool brands is reduced
Solution Approach 1:
The battery pack interface is designed with universal compatibility features, allowing the same battery pack to work with multiple tool brands and models. The dual rail interface system can accommodate both single rail interface tools and dual rail interface tools, enabling one battery pack design to serve multiple functions across different manufacturers.
3Adaptability or versatility
If a dual rail interface system is implemented, then the structural support and compatibility are improved, but the device complexity increases
Solution Approach 1:
The first rail set and second rail set are merged into a single integrated battery pack interface structure. This merging allows the dual rail interface system to provide enhanced structural support and compatibility while minimizing the increase in device complexity through unified design and construction.
