Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing devices and methods for harvesting poultry back meat from a carcass yield a reduced fraction and require complex and expensive equipment, leading to inefficient meat recovery.
Innovation Solution
A device comprising an endless conveyor with poultry carriers, pre-cutting and separation sections, and rotatable cutting elements that allow for the efficient separation of poultry back meat from the ribcage, enabling the harvesting of larger fillet sizes and reducing meat waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of substance
If conventional poultry processing devices are used, then back meat can be harvested, but the yield is reduced and equipment complexity increases
Solution Approach 1:
The device divides the cutting process into two sequential stages: a pre-cutting section that makes initial incisions to partially separate the back meat from the ribcage, and a separation section that completes the separation. This segmentation allows each section to be simpler in design while collectively achieving high back meat yield through systematic progressive cutting.
Solution Approach 2:
The pre-cutting section performs preliminary cutting actions before the final separation. By making initial incisions and partial separations upstream, the main separation section only needs to complete the cutting process, reducing its complexity and allowing the system to achieve high yield through preparatory work done in advance.
2Productivity
If conventional processing methods are used, then poultry can be processed, but the harvesting process is inefficient and waste increases
Solution Approach 1:
The conveyor continuously transports poultry carriers through both the pre-cutting section and the separation section in a single uninterrupted flow. This continuous processing eliminates idle time and intermediate handling steps, maintaining productive action throughout the harvesting process and reducing meat waste through efficient complete separation.
Solution Approach 2:
By segmenting the harvesting process into pre-cutting and separation stages, the system optimizes productivity at each stage. The pre-cutting section prepares the meat for efficient removal, and the separation section completes the task with minimal resistance, collectively achieving high harvesting efficiency and reduced waste.
3Manufacturing precision
If complicated equipment is used to harvest back meat, then separation can be achieved, but the device becomes expensive and complex
Solution Approach 1:
The device segments the cutting function into two simpler sections rather than one complex section. Each section handles a specific portion of the cutting task with simpler mechanics, yet together they achieve the precise separation required for high-quality back meat harvesting with reduced overall device complexity.
Solution Approach 2:
The pre-cutting section performs preliminary cutting actions that simplify the work required in the separation section. By preparing the meat structure in advance through controlled incisions, the final separation can be achieved with simpler, less complex cutting mechanisms while maintaining manufacturing precision.
