Battery Adapter for Power Tool Energy Source Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing power tool systems lack flexibility and convenience in energy supply, requiring multiple rechargeable battery packs compatible with specific tools and charging stations, and users face challenges when batteries are discharged without access to charging stations.
Innovation Solution
A power tool system that includes a rechargeable battery pack and a battery adapter with compatible mechanical and electrical interfaces, allowing reversible insertion and use of either energy source, enabling operation with either lithium-ion batteries or commercially available batteries, and featuring a two-part design for easy handling and protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Duration of action of moving object
If users employ multiple rechargeable battery packs for different power tools, then tool operation continuity is improved, but device complexity and cost increase
Solution Approach 1:
The battery adapter is designed with universal compatibility to fit multiple power tool types (drills, screwdrivers, saws, etc.) through a standardized interface. This allows a single battery adapter design to serve multiple functions across different tool categories, eliminating the need for users to purchase and manage multiple specialized battery packs for different tools.
Solution Approach 2:
The battery adapter acts as an intermediary component between the power tool holder and various battery types. It provides a standardized connection interface that mediates between the tool's required interface and different battery formats, allowing tools to operate with different battery types without requiring multiple specialized battery packs.
2Use of energy by moving object
If users rely on rechargeable battery packs, then energy supply is improved, but usability without charging station access deteriorates
Solution Approach 1:
The battery adapter supports multiple battery types including rechargeable batteries and disposable alkaline or lithium batteries. This multi-functionality allows users to operate power tools in locations without charging stations by simply replacing depleted rechargeable batteries with fresh disposable batteries, eliminating the dependency on charging station access.
3Ease of operation
If battery adapter uses two-part design, then ease of handling is improved, but device complexity increases
Solution Approach 1:
The battery adapter is divided into two main parts: a body portion that interfaces with the power tool holder and a cap portion that covers and secures the battery compartment. This segmentation allows each part to be optimized for its specific function and enables users to handle and assemble the adapter in a simple, intuitive manner without complex assembly procedures.
4Object-affected harmful factors
If battery adapter fully encloses battery, then protection from environmental damage is improved, but ease of battery replacement deteriorates
Solution Approach 1:
The battery adapter's two-part design with a removable cap portion provides full enclosure and environmental protection for the battery while maintaining easy accessibility. Users can quickly open the cap to replace batteries without complex tools or procedures, and the cap securely closes to protect the battery compartment from dust, moisture, and other environmental factors.
