Battery Holder Opening Layout for Easy Tool Battery Removal
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric working machines require complex mechanisms, such as switches and spring members, to facilitate easy battery removal, which complicates the design and functionality.
Innovation Solution
A simple configuration featuring a battery holding portion with a first opening for insertion and a second opening positioned away from the battery's front end, allowing easy removal by applying a force through the second opening, thereby eliminating the need for additional mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a special mechanism such as a switch and a spring member is used to facilitate removal of the battery, then the battery can be easily removed, but the device complexity increases
Solution Approach 1:
The patent extracts the battery removal function from a complex mechanical mechanism and implements it through a simple opening structure. The second opening provides direct access to the battery, allowing users to remove it by simply pushing through the opening without requiring switches, spring members, or other complex components.
Solution Approach 2:
The battery holding portion is segmented into multiple openings: a first opening for battery insertion and a second opening for battery removal. This segmentation allows independent access paths for different operations, enabling simple battery removal through the second opening while maintaining secure holding through the first opening's structure.
2Device complexity
If a simple configuration is used for battery holding, then the device complexity is reduced, but the ease of battery removal deteriorates
Solution Approach 1:
The battery holding portion is divided into multiple functional openings: the first opening maintains secure battery holding with minimal structure, while the second opening provides dedicated access for removal. This segmentation achieves both simple configuration and easy removal functionality simultaneously.
Solution Approach 2:
The second opening acts as an intermediary structure that facilitates battery removal without requiring complex mechanisms. It provides a direct access path that mediates between the user's removal action and the battery, enabling easy removal while keeping the overall configuration simple.
