Spring-Loaded Latch for Power Tool Belt Holder
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tool belts are inadequate for holding larger hand-held power tools like nail guns and electric drills, as they are too bulky and require users to stop work to retrieve them when out of reach.
Innovation Solution
A tool holder with a flat strap forming a belt loop and tool loop, equipped with a spring-loaded mechanical latch that allows quick release and secure holding of battery-powered tools between the battery pack and the tool housing, enabling secure attachment to a user's apparel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional tool belts are used to hold tools, then small hand tools can be carried conveniently, but larger power tools cannot be held securely and remain out of reach
Solution Approach 1:
The tool holder is divided into distinct functional segments: a belt loop portion for attachment to apparel, a tool loop portion for securing the power tool, and a mechanical latch mechanism for controlled release. This segmentation allows each part to perform its specific function effectively, enabling secure holding of larger tools while maintaining wearability.
Solution Approach 2:
The mechanical latch mechanism provides dynamic control over tool retention. The spring-loaded latch automatically engages to secure the tool, while the thumb bar allows quick manual disengagement when needed. This dynamic system adapts between secure holding and rapid release states, solving the contradiction between security and accessibility.
2Productivity
If larger power tools are laid down when not in use, then they can be stored, but the user must stop work to retrieve them when out of reach
Solution Approach 1:
The tool holder is positioned on the user's belt or apparel, placing the power tool within immediate reach before work begins. The tool is preliminarily positioned in an accessible location, eliminating the need to stop work and search for tools during use. This preliminary positioning maintains continuous productivity.
Solution Approach 2:
The mechanical latch with thumb bar enables the user to quickly release and resecure the tool independently without assistance. The spring mechanism automatically re-engages the latch after release, allowing rapid tool access and return to work without time loss or external help.
3Reliability
If a mechanical latch is added to secure larger tools, then tool holding security improves, but device complexity increases
Solution Approach 1:
The complex aspects of tool securing are extracted into a dedicated, self-contained mechanical latch mechanism that is separate from the main belt and tool loop structures. This extracted mechanism handles the security function independently, allowing the rest of the device to remain simple while achieving reliable tool retention.
Solution Approach 2:
The spring-loaded latch mechanism is self-actuating and self-latching. Once the tool is inserted, the spring automatically engages the latch to secure it. The thumb bar provides simple manual override for release, and the spring automatically re-engages afterward. This self-service mechanism achieves high reliability without requiring complex control systems or multiple components.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables convenient, quick access and secure storage of hand-held power tools near the user, preventing the need to stop work to retrieve tools and ensuring they remain within reach.
Implementation Method 1
The mechanical latch is spring loaded to keep the tool loop closed
Implementation Method 2
The mechanical latch is spring loaded to keep the tool loop closed except when the user disengages the mechanical latch

AI summary
A tool holder designed for battery operated power tools is attachable to a belt and has a quick release to allow access to the power tool. The tool holder grasps the power tool at the handle between the battery pack of the tool and the housing containing the operative part. The tool holder is made of a flat material such as metal or a high-density plastic and comprises a mechanical latch that secures the power tool within the holder until the user disengages the latch to allow removal of the tool.
