Pivoting Deer De-hide Tool with Biasing Spring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for skinning animals, such as using knives, are inefficient and require manual effort to cut and pull the hide from around the legs, lacking a tool to assist in this process effectively.
Innovation Solution
A foldable cutting tool with opposable handles and a pivotally connected mechanism, featuring serrated jaws and a biasing spring for easy operation, along with a cutting blade and hook design to facilitate the cutting and removal of animal hides.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a knife is used to cut the hide around the legs, then the cutting function is achieved, but the manual effort and efficiency are insufficient
Solution Approach 1:
The patent combines multiple functions into a single tool: the opposable handles with cutting edges provide both gripping and cutting capabilities, while the hook element integrates the hide removal function. This merging of functions eliminates the need for separate tools and reduces manual effort by allowing the user to perform multiple operations with one device.
Solution Approach 2:
The tool features dynamic elements including the opposable handles that can open and close around the animal leg, and the hook that can be positioned and engaged at different locations. The biasing mechanism provides dynamic force assistance, automatically maintaining the cutting edge penetration as the tool moves through the hide, thereby reducing the manual effort required.
2Productivity
If manual gripping and pulling is used to remove the hide, then the hide can be removed from the leg, but the operation is time-consuming and labor-intensive
Solution Approach 1:
The tool merges the gripping function (through opposable handles with gripping surfaces) and the cutting function (through cutting edges on the handles) into a single integrated operation. The user can simultaneously grip the hide and apply cutting force, eliminating the separate steps of gripping then cutting, thereby reducing skinining time.
Solution Approach 2:
The biasing mechanism ensures continuous application of cutting force as the tool moves through the hide. The spring-loaded or spring-assisted mechanism maintains constant pressure on the cutting edges, allowing continuous cutting action without interruption or repeated manual adjustments, thus reducing the time required for hide removal.
3Reliability
If a simple cutting tool is used, then the device complexity is low, but the ability to maintain secure grip and cutting penetration is insufficient
Solution Approach 1:
The opposable handles are designed with gripping surfaces and cutting edges integrated into the same structural element. This merging allows the tool to provide both secure grip and effective cutting without requiring additional separate components, maintaining reliability while controlling complexity.
Solution Approach 2:
The biasing mechanism provides dynamic force assistance that automatically maintains cutting edge penetration during operation. This dynamic force application ensures reliable cutting performance without requiring complex manual pressure control mechanisms, thereby achieving reliability with moderate complexity.
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
The tool allows for efficient cutting and removal of hides with reduced manual effort, maintaining a secure grip and facilitating the skinning process by allowing the tool to be easily opened and closed around the animal's leg, with the biasing mechanism assisting in maintaining the cutting edge penetration.
Implementation Method 1
a biasing spring positioned between the handles behind the pivot point, which may be only attached to one handle

AI summary
A tool having a first and second handle, pivotally coupled between a tool open position and a tool closed position, each handle having a working end and a gripping end. A jaw is positioned on each working end, and each handle has a cutout positioned between the working end and the jaw, where the cutouts are aligned to create an opening in the tool when closed. The tool has a first cutting blade having a first cutting surface, where the first cutting blade is removably attached to one of the handles. One of said handles also has a rearward fixed projecting finger, positioned intermediary the jaws and the pivot point of the tool handle.
