Adjustable Gambrel Suspension Bar for Stable Animal Butchering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gambrels lack adjustability and adaptability to accommodate animals of varying sizes, from small game like ducks to large feral hogs, often resulting in insecure suspension and instability during butchering.
Innovation Solution
A gambrel with an adjustable length suspension bar featuring elongated members with slots and apertures, stainless steel wire cables, and egg-shaped snap hooks, allowing for secure suspension of animals of different sizes by maintaining constant cable geometry and tension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed-length suspension bar is used in traditional gambrels, then the structure is simple and easy to manufacture, but it cannot accommodate animals of varying sizes from ducks to large feral hogs
Solution Approach 1:
The suspension bar is designed as a telescopic mechanism with nested elongated members that can extend and retract. The first elongated member contains a passageway through which the second elongated member slides, allowing the bar length to be dynamically adjusted based on animal size while maintaining structural integrity through slots and apertures that secure the cable geometry.
Solution Approach 2:
The suspension bar is divided into separate elongated members (first and second members) that can be independently positioned and secured. Each member has its own passageway, slot, and aperture, allowing modular adjustment of the bar length by inserting and securing different combinations of members together.
2Adaptability or versatility
If the suspension bar length is adjusted to fit different animals, then adaptability improves, but the cable geometry and tension may change causing instability
Solution Approach 1:
The cable is pre-configured with specific geometric relationships and tension characteristics. The slots and apertures are positioned to maintain predetermined cable angles and tension distribution. When the bar length is adjusted, the cable ends remain secured at these pre-determined positions, preserving the original cable geometry and tension characteristics regardless of the bar length change.
3Strength
If traditional gambrels are used for small animals like ducks, then the device is simple, but it becomes unstable and insecure when used for large animals like feral hogs
Solution Approach 1:
The gambrel system allows changing the effective length parameter of the suspension bar by extending or retracting the telescopic members. This parameter change enables the same device to provide appropriate geometric relationships and cable tension for both small animals (shorter bar configuration) and large animals (longer bar configuration), ensuring secure and stable suspension across the full size range.

AI summary
A gambrel for hanging an animal to be butcher or skinned, the gambrel having an adjustable length suspension bar from which lines extend to be wrapped around the legs of the animal to be butchered or skinned. The adjustable length suspension bar consists of one elongated member inserted into another elongated member. Each elongated member has a slot through which each end of a gambrel suspension line is extended into and retained within each elongated member so that the geometry of the gambrel suspension line remains the same when length of the adjustable length suspension bar is changed to accommodate different sized animals.
