Battery Tool Holder Structure for Strap-Free Secure Retention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional tool holders for battery-powered tools often require additional retaining straps to prevent the battery from pulling the tool out, and they typically hold the tool in a horizontal orientation with the battery and power head at the same height, making it cumbersome for user access and storage.
Innovation Solution
A tool holder with a body comprising parallel lateral panels and a central panel that encloses the battery, allowing attachment to various structures, and inwardly extending portions to support the battery without direct contact with the power head, enabling secure retention in various orientations without additional straps.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional tool holders use additional retaining straps to prevent battery from pulling tool out, then tool retention reliability is improved, but device complexity increases
Solution Approach 1:
The patent extracts the retaining function from separate straps and integrates it into the holder body structure itself. The battery-engaging portion and lateral panels form an integrated structure that retains the tool through its geometry rather than requiring additional retaining components.
Solution Approach 2:
The patent merges the retaining function with the holder body structure. The lateral panels, central panel, and battery-engaging portion work together as a unified structure to secure the tool, eliminating the need for separate retaining straps.
2Stability of the object's composition
If conventional tool holders hold tool in horizontal orientation with battery and power head at same height, then tool stability is improved, but ease of operation deteriorates due to cumbersome user access and storage
Solution Approach 1:
The patent enables the tool holder to accommodate multiple orientations (inverted, horizontal, intermediate) rather than fixing it in a single horizontal position. The asymmetric design with the battery engaged at one end allows dynamic adaptation to different carrying and access scenarios, improving ease of operation while maintaining stability.
Solution Approach 2:
The patent specifically enables inverted orientation where the battery is at the bottom and power head extends upward, opposite to conventional horizontal positioning. This inversion allows the tool to be carried in the holder and accessed more conveniently while the battery weight provides natural stabilization.
3Ease of manufacture
If conventional tool holders require additional retaining straps, then manufacturing cost increases, but if the patent uses integrated holder structure, then manufacturing cost decreases
Solution Approach 1:
The patent combines the retaining function into the main holder structure, reducing the total number of parts that need to be manufactured and assembled. This integration simplifies manufacturing while maintaining reliable tool retention through the engineered geometry of the lateral panels and battery-engaging portion.

AI summary
A tool holder includes a body and mounting hardware, and holds a battery-powered tool. The body includes central and lateral panels that partly enclose and retain the battery of the tool. The mounting hardware is attached to a lateral panel and attaches the tool holder to a separate object or structure. The lateral panels have inwardly extending portions at their edges that support the enclosed battery and obstruct its movement away from the central panel and out of the body. The inwardly extending portions are spaced apart at a first end of the body, enabling insertion of the battery into the body with a handle portion of the tool extending away from the central panel. The tool holder retains and supports the tool with the battery retained within the body and without any other direct contact between the tool and the tool holder.
