Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction workers face challenges in safely and efficiently switching between multiple tools, such as hammers and nail guns, while working at height, leading to dangerous and time-consuming situations due to the need for one-handed tool exchanges.
Innovation Solution
A combination hammer/tool holder with a backer, hammer support bar, and accessory support bar that allows for secure storage and quick access to multiple tools using clips with spring bars, enabling one-handed holstering and re-holstering.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a worker uses multiple tools sequentially while working at height, then the worker can complete various construction tasks, but the worker faces safety risks and time loss during one-handed tool exchanges
Solution Approach 1:
The patent combines multiple tool-holding functions into a single integrated holder that can simultaneously secure both a hammer and a nail gun (or other air tools). The holder integrates a hammer support bar with an accessory support bar, creating a unified device that eliminates the need for separate holders and enables safe one-handed tool exchanges while maintaining versatility.
Solution Approach 2:
The holder is designed with universal functionality to accommodate different tool combinations. It can hold a hammer in the hammer support area while simultaneously securing an air tool (nail gun, screw gun, etc.) in the accessory support area via a clip mechanism. This multi-functional design allows workers to switch between different tool pairs without needing multiple specialized holders.
2Reliability
If a worker secures one tool in a traditional holder, then the tool is safely stored, but the worker cannot quickly access or exchange tools
Solution Approach 1:
The holder pre-positions multiple tools in ready-to-use positions with clear access paths. The hammer is held with the head visible and accessible, while the air tool is secured in the accessory area with a quick-release clip mechanism. This preliminary arrangement eliminates the need for workers to search for or manually manipulate tools during exchanges, enabling rapid one-handed swaps while maintaining secure storage.
Solution Approach 2:
The holder incorporates a dynamic clip mechanism with a spring bar that can be quickly actuated to release the air tool. The clip transitions from a locked position (securing the tool) to an open position (allowing quick removal) through simple one-handed motion. This dynamic element enables rapid tool exchange while maintaining secure holding during storage.
3Adaptability or versatility
If a worker uses separate holders for different tools, then each tool has dedicated storage, but the overall device complexity and belt burden increase
Solution Approach 1:
The patent merges the functionality of multiple separate holders into a single integrated device. The hammer support bar and accessory support bar are combined into one unified holder structure that can simultaneously secure different tool types. This consolidation reduces the number of separate components needed and simplifies the overall configuration while maintaining the ability to support multiple tools.
Solution Approach 2:
The integrated holder provides universal support for different tool combinations through its dual-area design. The hammer support area accommodates hammers of various sizes, while the accessory support area with its adjustable clip mechanism can secure air tools, screw guns, or other equipment. This universal design eliminates the need for multiple specialized holders, reducing complexity while maintaining versatility.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Facilitates safe and efficient storage and access to multiple tools on a belt, reducing the risk of accidents and improving workflow efficiency by allowing one-handed tool exchanges and secure attachment to the belt or work surfaces.
Implementation Method 1
the attachment portion having an open area enclosable by a spring bar forming a gate, the spring bar having a biased closed position enclosing the open area

AI summary
A tool support device includes a backer having a planar surface; a hammer support bar, the hammer support bar having a first portion extending perpendicular to the planar surface and a second portion attached to the planar surface such that the hammer support bar and the backer form an open hammer support area; an accessory support bar extending parallel to the first portion of the hammer support bar and being associated with the hammer support bar, the accessory support bar and the open hammer support bar forming an open accessory area outside the bounds of the open hammer support area. The open hammer support area supports the head of a hammer while the handle of the hammer is passed therethrough and the open accessory area permits a clip to be clipped onto the accessory support bar. A spring loaded clip specifically configured for this purpose may also be provided.
