Solution Overview

Problem

Conventional deboning methods for bone-in meat, such as chicken drumettes, are labor-intensive and inefficient, with manual separation requiring significant effort and time, and existing automation systems do not effectively address the challenge of varying meat piece lengths or ensure high yield and product quality by preventing bone fragment contamination.

Innovation Solution

A deboning apparatus comprising a clamper, cutters, elastic meat-portion peeling members, and a control system that adjusts the peeling force and detection mechanisms to automate the separation process, ensuring high yield and preventing bone fragment contamination by using a clamper to hold the meat, making circumferential cuts, and using peeling members that apply elastic force to separate the meat portion while detecting the gap between peeling members to optimize cutting timing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If manual deboning is used, then product quality can be maintained through careful handling, but labor time and effort increase significantly

Engineering Contradiction:
Improveproduct qualityVSAvoidlabor time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent replaces manual mechanical deboning operations with an automated mechanical system comprising a clamper, cutters, and elastic peeling members. The system uses controlled mechanical forces to separate meat from bone, eliminating manual labor while maintaining product quality through precise control of the deboning parameters.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The elastic peeling members automatically adapt to the meat portion thickness and bone shape during the peeling process. The elastic force is applied dynamically based on the actual contact conditions, allowing the system to self-adjust without manual intervention for each varying piece of meat.

Inventive Principle:
Principle #25Self-service

2Reliability

If the meat separator moves along the entire length to completely separate meat from bone, then complete deboning is achieved, but meat yield decreases due to excessive cutting

Engineering Contradiction:
Improvedeboning completenessVSAvoidmeat yield
Core Design Contradiction:
ReliabilityVSLoss of substance

Solution Approach 1:

The system performs a preliminary circumferential cut around the bone at the initial stage, creating a separation line that allows the meat to be peeled away in one continuous motion. This preliminary action prevents the need for multiple cutting passes along the entire length, thereby preserving meat yield while achieving complete deboning.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The deboning process is segmented into two distinct stages: (1) making a circumferential cut around the bone, and (2) peeling the meat away using elastic members. This segmentation allows the meat to be separated in one efficient motion rather than requiring continuous cutting along the entire bone length.

Inventive Principle:
Principle #1Segmentation

3Productivity

If the meat separator is moved quickly to improve productivity, then processing speed increases, but bone fragments may contaminate the meat portion

Engineering Contradiction:
Improveprocessing speedVSAvoidbone fragment contamination
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The elastic peeling members are designed to provide cushioning force during the peeling process. This elastic cushioning absorbs shocks and prevents excessive force from being applied to the bone, thereby preventing bone fragments from breaking off and contaminating the meat even during high-speed operation.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The system changes the force parameter dynamically by using elastic members that automatically adjust the applied force based on contact conditions. This allows high-speed operation while maintaining controlled force levels that prevent bone fragmentation.

Inventive Principle:
Principle #35Parameter changes

4Device complexity

If fixed-force peeling members are used, then device complexity is reduced, but inability to adapt to varying meat lengths reduces versatility

Engineering Contradiction:
Improvepeeling mechanism simplicityVSAvoidadaptability to varying meat lengths
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The peeling members are made elastic to enable automatic adjustment of the applied force parameter. This allows the same simple device structure to adapt to varying meat lengths and thicknesses without requiring complex control systems or multiple adjustable components.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The system transitions from static fixed-force members to dynamic elastic members that automatically adjust their force output based on the actual work conditions. This dynamic adaptation allows the simple device to handle varying meat lengths effectively.

Inventive Principle:
Principle #15Dynamics
