Multi-Purpose Hand Tool With Perpendicular Staple Extractor
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional fencing pliers often damage fence posts during staple removal due to the orientation of their tapered ends and compromised leverage, which hampers efficient installation and repair tasks.
Innovation Solution
A hand tool with a body having pivotally connected sides and a perpendicular extraction member, featuring a first and second leg member, and a tapered tip for improved leverage, which minimizes post damage and enhances staple extraction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the tapered end is integrally formed with the jaw member in the same orientation, then the tool structure is simple, but the fence post is damaged during staple removal
Solution Approach 1:
The extraction member is oriented perpendicular to the jaw members, changing the dimensional orientation from the traditional in-line configuration. This perpendicular arrangement allows the extraction member to engage staples without the jaw members contacting the fence post, thereby preventing post damage while maintaining structural simplicity
2Device complexity
If the conventional pivotal connection design is used, then the device complexity is low, but the leverage for pulling staples is compromised
Solution Approach 1:
By positioning the extraction member perpendicular to the jaw members at the pivotal connection point, the tool creates a more effective lever arm for staple removal. This dimensional change optimizes the mechanical advantage without adding complex mechanisms, as the perpendicular orientation naturally provides greater leverage

AI summary
A hand tool that is configured to assist a user in the performance of tasks commonly associated with installation and repair of fencing. The invention includes a body having a first side and a second side. The first side and second side of the body are pivotally coupled at a central axis point. The central axis point is surroundably mounted by a hub member. A head portion includes a first main jaw member and a second main jaw member. An extraction member is operably coupled to the head portion being perpendicular thereto extending outward therefrom. The extraction member includes a first leg member and a second leg member having a void therebetween. The extraction member includes an upper portion contiguous with the leg members wherein the upper portion has an outer peripheral edge having an arcuate section forming a tip operable to engage an object such as a fence staple.
