X-ray Carcass Imaging for Automated Cutting Path Determination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current automated carcass cutting systems face challenges in replicating the precision of skilled butchers, particularly in determining the correct cutting positions on animal carcasses, and existing X-ray imaging methods require costly and complex setups that are not suitable for high-throughput vertical processing operations.
Innovation Solution
The method involves using a single X-ray source and detector to capture images from different perspectives as the carcass is moved along a conveyor rail and rotated 180 degrees, allowing for precise determination of cutting paths without the need for multiple X-ray systems or horizontal carcass orientation, thereby reducing costs and radiation exposure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple X-ray systems are used to capture images from different perspectives, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent combines multiple imaging functions into a single X-ray system by capturing images at different time points during conveyor movement. Instead of using multiple simultaneous X-ray systems, one system captures sequential images as the carcass moves through the imaging zone, merging the functionality of multiple systems into a single integrated unit.
Solution Approach 2:
The patent adds the time dimension to the imaging process by capturing images at different moments as the carcass moves along the conveyor. This temporal dimension allows a single X-ray system to obtain multiple perspectives that would traditionally require multiple simultaneous systems, transforming a spatial problem into a temporal solution.
2Measurement precision
If carcass is oriented horizontally on trolley fixture for X-ray imaging, then measurement precision is improved, but productivity and space utilization worsen
Solution Approach 1:
The patent inverts the traditional horizontal imaging approach by implementing vertical imaging while the carcass hangs from the conveyor. Instead of requiring the carcass to be reoriented horizontally on trolleys, the X-ray system is configured to image the carcass in its natural vertical hanging position, eliminating the need for complex reorientation mechanisms.
Solution Approach 2:
The imaging system is designed to work with the carcass in its standard vertical conveyor position, making the system compatible with existing processing lines without requiring specialized horizontal positioning fixtures. The same conveyor system used for transport also positions the carcass for imaging, eliminating the need for separate horizontal positioning infrastructure.
3Measurement precision
If two X-ray systems are mounted on either side of the carcass, then measurement precision is improved, but radiation dosage increases
Solution Approach 1:
The patent merges the imaging function of what would traditionally require two simultaneous X-ray systems into a single system that captures sequential images. By using one X-ray source instead of two, the total radiation dosage to the carcass is reduced while still achieving the necessary measurement precision through temporal separation of images.
4Measurement precision
If trolleys are used to position carcass horizontally, then measurement precision is improved, but ease of operation worsens due to cleaning and maintenance requirements
Solution Approach 1:
The patent extracts the complex horizontal positioning trolley system from the imaging process and eliminates it entirely. By imaging the carcass in its natural vertical hanging position on the conveyor, the system removes the need for specialized horizontal positioning fixtures that require cleaning and maintenance, simplifying the overall operation.

AI summary
A method of determining a cutting path for processing an animal carcass based on X-ray imaging. The carcass is preferably imaged using a single X-ray source and a single detector - preferably a fan beam and linear detector. The carcass is preferably hung from a conveyor rail during imaging and conveyed throughout all processing on a continuous conveyor rail. The carcass is preferably imaged by passing the carcass though the imaging system along different paths to produce images from two perspectives to enable the spatial configuration of elements of the carcass to be determined. The imaging information may also be used to grade the carcass.
