Pivotable Plate Meat Removing Device for Irregular Bone Deboning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for deboning carcass leg parts of four-legged slaughter animals, particularly those with irregular profiles like the humerus and femur bones, are inefficient and prone to muscle rupture, lacking in operator ergonomics and automation.
Innovation Solution
A method and system involving a support device that holds the leg by the lower end of the bone, a meat removing device with multiple pivotable plates that follow the bone's contour, and a controlled movement pattern to sever muscle fibers and remove meat efficiently, including pre-cutting and iterative movements to ensure robust and reliable deboning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual deboning methods are used on bones with irregular profiles, then the process is flexible, but the efficiency is low and muscle rupture occurs frequently
Solution Approach 1:
The meat removing device is designed with multiple pivotable plates that can dynamically adjust their positions and orientations to follow the irregular contour of different bone shapes. This dynamic adaptability allows the device to maintain effective contact with meat across varying bone geometries, improving deboning efficiency while preventing muscle rupture through controlled, adaptive movement rather than rigid force application
Solution Approach 2:
The meat removing device is segmented into multiple independent plates that can pivot and move relative to each other. This segmentation allows each plate to independently adapt to local bone contours while collectively covering the entire bone surface, enabling efficient meat removal without concentrating stress on single points that could cause muscle rupture
2Ease of operation
If automated deboning systems are implemented, then operator ergonomics improve, but the system complexity increases
Solution Approach 1:
The system employs a dynamically adjustable meat removing device with pivotable plates that can adapt to different bone geometries automatically. This dynamic design reduces the need for multiple specialized tools and manual adjustments, simplifying operator interaction while maintaining high automation capability, thus improving ergonomics without proportionally increasing system complexity
Solution Approach 2:
The meat removing device with its multiple pivotable plates serves multiple functions: it can process various bone shapes and sizes, adjust to different meat distributions, and operate in different positions. This multi-functionality consolidates what would otherwise require multiple specialized devices into a single system, improving operator ergonomics while controlling overall system complexity
3Reliability
If iterative meat removing movements are executed, then meat is removed more reliably from bone, but the processing time increases
Solution Approach 1:
The iterative meat removing movements are designed to be continuous and overlapping, with each pass removing a layer of meat and exposing new surfaces for subsequent passes. The pivotable plates maintain continuous contact with the bone, and the iteration process is streamlined to minimize idle time, ensuring reliable meat removal while optimizing processing speed through uninterrupted action
Solution Approach 2:
The system performs partial meat removal in each iterative pass, focusing on specific regions rather than attempting complete removal in a single action. This partial action approach allows multiple targeted passes to efficiently remove all meat through cumulative effect, improving reliability while managing total processing time through strategic, focused iterations

AI summary
A method and system of removing meat from a bone of a carcass leg part, comprising the subsequent steps of: a) holding, by a support device, of the leg part, b) moving a meat removing device: into a pre-cut, c) then away from the support device along the bone to a first end position so that meat is removed from the bone, d) then away from the bone, forcing meat away from the bone and severing further meat from the bone, e) then towards the support device, f) and then towards the bone, g) and then again away from the support device along the bone to a second end position distanced further from the support device than the first end position so that further meat is removed from the bone.
