Poultry Deboner Holder Assembly for Bone Integrity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing deboning devices for poultry legs and wings face issues with maintaining the position of the leg or wing parts during the deboning process, leading to potential buckling, bone breakage, and inefficient meat yield due to incorrect placement and excessive stripping forces.
Innovation Solution
A device with a holder assembly that includes first and second holder means for maintaining the position of the leg or wing parts, allowing axial movement and rotation about the bone axis, along with a circular blade for efficient meat separation, and additional features like gripper means and stripping mechanisms to ensure stable positioning and increased meat yield.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If large stripping forces are exerted on the chicken leg during deboning, then the deboning process can be completed, but the knee joint is able to buckle through against the stationary straight bar, causing the drum stick bone to end up beyond the hollow cylinder blade and the thigh bone to break
Solution Approach 1:
The straight bar is made movable instead of stationary, allowing it to move in the direction of the drumstick bone during deboning. This dynamic adjustment prevents the knee joint from buckling through while maintaining the stretched position, thus preventing bone breakage while enabling complete deboning.
Solution Approach 2:
A second movable straight bar is introduced as an intermediary element that works in conjunction with the first straight bar. This second bar provides additional support and control during the deboning process, helping to maintain proper positioning and prevent bone breakage while allowing large stripping forces to be applied.
2Ease of operation
If the diameter of the cylinder blade is adapted to accommodation of the knee joint, then the knee joint can be processed, but usable meat is left behind around the bones
Solution Approach 1:
The cylinder blade is made movable in the direction of the drumstick bone, allowing its diameter to be dynamically adjusted. This enables the blade to first accommodate the knee joint with a larger effective diameter, then move to a position where it can more closely follow the bone contour, thereby reducing meat waste while maintaining ease of operation.

AI summary
Deboning modules 50 move along a processing path for deboning poultry legs or wings having bones connected by an intermediate joint. The modules each include an ankle knuckle holder 60 and a hip knuckle holder 90 for supporting the leg and the hip bone in alignment with each other. Stripping claw 154 and hip knuckle holder 90 move toward each other for stripping meat from the leg bone and hip bone toward the intermediate leg joint. A cylinder blade 71 moves about the ankle knuckle holder toward the hip knuckle holder for cutting the accumulated meat at the hip knuckle holder.
