Battery Holder Openings for Easy Removal in Power Tools
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 multiple openings, including 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, utilizing the battery's weight for insertion and providing a non-slip surface for stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a detachable battery is used, then the battery can be removed and replaced, but the removal process becomes difficult without additional mechanisms
Solution Approach 1:
The battery holding portion is divided into multiple functional regions: a first opening for insertion, a holding space for securing the battery, and a second opening for removal. This segmentation allows each region to perform its specific function efficiently, making the battery easily removable through the second opening without requiring complex additional mechanisms.
Solution Approach 2:
The second opening acts as an intermediary structure that facilitates battery removal. By providing this intermediate access point separate from the insertion opening, users can easily grasp and remove the battery without needing switches, spring members, or other complex release mechanisms.
2Ease of operation
If complex mechanisms like switches and spring members are added to facilitate battery removal, then battery removal becomes easier, but the device complexity increases
Solution Approach 1:
The invention extracts the essential function of battery removal from complex mechanical mechanisms and implements it through a simple structural feature—the second opening. This eliminates the need for switches, spring members, and other complex components while maintaining easy battery removal capability.
Solution Approach 2:
The battery holding portion structure itself provides the removal function through its own design features (the second opening), rather than requiring separate control mechanisms. The structure serves its own purpose of facilitating easy battery removal without needing external assistance from complex mechanisms.
3Ease of manufacture
If the battery holding portion has a simple configuration, then the device is easier to manufacture, but battery removal may become difficult
Solution Approach 1:
The battery holding portion is segmented into simple geometric features: a first opening for insertion, a holding space for securing, and a second opening for removal. This segmentation achieves easy battery removal through simple structural elements that are straightforward to manufacture, avoiding complex mechanisms while maintaining operational ease.

AI summary
A simple configuration is provided to facilitate removal of a battery. An electric working machine comprises an electric working portion and a main body portion. The electric working portion is configured to operate by electric power supplied from a battery. The main body portion includes a battery holding portion having a holding space for inserting the battery in an insertion direction and holding the battery. The battery holding portion includes a plurality of openings including a first opening through which the battery passes when inserted and a second opening provided at a position that is separated from a front end of the battery held in the holding space in the insertion direction.
