Battery Holder Elastic Support for Compact Power Tool Impact Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electric power tools with battery mounts face challenges in effectively absorbing vibration and impact without increasing the tool's size, as current solutions require more or larger elastic members.
Innovation Solution
The electric power tool employs a distributed elastic support system with first, second, and third elastic bodies located at different points to absorb vibration and impact, allowing the battery holder to displace and absorb shocks without increasing the tool's size.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If more elastic members are used to increase vibration absorption capacity, then the vibration damping property is improved, but the size of the electric power tool increases
Solution Approach 1:
The battery holder is divided into multiple sections, each supported by its own elastic member (first elastic body, second elastic body, third elastic body). This segmentation allows vibration absorption to be distributed across multiple points rather than requiring a single large elastic member, thus improving vibration damping while maintaining compact size.
Solution Approach 2:
Different elastic members are positioned at specific locations (first elastic body between tool body and battery holder, second elastic body between holder main body and terminal, third elastic body on tool body facing battery lower surface) to provide localized vibration absorption and impact resistance where most needed, optimizing the balance between protection and size.
2Reliability
If larger elastic members are employed to increase vibration absorption capacity, then the impact resistance is improved, but the size of the electric power tool increases
Solution Approach 1:
The impact absorption function is segmented across three separate elastic members positioned at different locations. The first elastic body absorbs impact between the tool body and battery holder, the second elastic body protects the terminal connection, and the third elastic body cushions the battery lower surface. This distributed approach provides comprehensive impact resistance without requiring any single elastic member to be large.
Solution Approach 2:
The elastic members are pre-positioned to provide cushioning before impact occurs. The first elastic body is already between the tool body and battery holder, the second elastic body is between the holder main body and terminal, and the third elastic body is on the tool body facing the battery lower surface, ready to absorb impact forces before they reach critical components.

AI summary
A battery holder supported by a main body housing so as to be displaceable in an up-down direction has a main body extension, a holder lower portion at a lower part, and a terminal supported by the battery holder so as to be displaceable in the up-down direction. The battery holder has a first elastic body interposed between the main body housing and the battery holder, a second elastic body interposed between the battery holder and the terminal, and a third elastic body interposed between the holder lower portion and the main body housing. The first to third elastic bodies absorb impacts in the event of a drop, thereby reducing damage to the battery.
