Multi-Purpose Hand Tool With Integrated Fastener Holding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Construction and maintenance activities often face challenges due to limited accessibility of diverse tools at worksites, particularly when repairing or replacing barriers like wire fences, which can compromise site safety and efficiency.
Innovation Solution
A multi-purpose hand tool with pivotally connected sides, featuring a hammer head, recesses for holding different types of fasteners, and a claw for tines, allowing for simultaneous handling of multiple tasks like hammering and fastening without needing to hold fasteners with the other hand, enhancing safety and reducing the need for multiple tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple separate tools are used for hammering and fastening operations, then functional versatility is improved, but device complexity and transportation requirements worsen
Solution Approach 1:
The patent combines a hammer head, fastener holder, and claw into a single integrated hand tool body. The hammer head is positioned at one end of the tool body with a shaft extending downward, while the claw extends outwardly at the opposite end. Fastener holders are integrated into the tool body structure, allowing multiple functions (hammering, fastening, nail pulling) to be performed with one tool rather than requiring separate tools for each function.
Solution Approach 2:
The hand tool is designed to perform multiple functions: the hammer head for striking fasteners, the integrated fastener holders for storing and accessing fasteners, and the claw for removing nails or fasteners. This multi-functional design allows a single tool to replace multiple specialized tools, improving versatility while reducing the number of tools needed.
2Ease of operation
If fasteners are held in one hand while operating tools, then operational control is improved, but safety worsens due to reduced hand availability for alignment
Solution Approach 1:
The tool incorporates integrated fastener holders that automatically retain and present fasteners during operation. The fastener holders are positioned on the tool body and include features like grooves or magnetic elements that securely hold fasteners in place. This self-service mechanism eliminates the need for the operator to manually hold fasteners with one hand while operating the tool with the other, as the tool itself provides fastener retention and presentation.
3Adaptability or versatility
If diverse tools are transported to remote worksites, then task capability is improved, but accessibility and transportation ease worsen
Solution Approach 1:
The patent integrates multiple tool functions (hammer, fastener holder, claw) into a single hand tool assembly. This consolidation reduces the number of separate tools that need to be transported to remote worksites. The unified tool body with integrated components allows operators to carry one tool instead of multiple tools, improving transportation ease while maintaining task capability for hammering, fastening, and nail removal operations.

AI summary
A multi-purpose hand tool includes a first side and a second side that are pivotally connected. The first side includes a lower end having a first handgrip and an upper end including a shaft having a hammer head at one end; a first recess extending at least partially along a bottom of the shaft for holding one or more straight fasteners; and a second recess located substantially in a bottom part of the hammer head for holding one or more rounded fasteners.
