Carcass Cutting System with Guide Pin Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for cutting open the belly and breast of animal carcasses, such as pig carcasses, face challenges in maintaining a straight and symmetrical cut due to destabilization forces, leading to non-straight cuts and meat quality issues.
Innovation Solution
A cutting system that stabilizes the carcass by applying a combination of internal and external forces using a guide pin and pressure device, ensuring a local pulling and pushing effect to maintain the carcass's stability during the cutting process, allowing for a straight cut from the pubic bone to the pharynx or stick hole.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a belly opener with a knife is used to cut from the pubic bone towards the throat, then the cutting function is achieved, but the forces applied destabilize the hanging carcass making it difficult to perform a straight cut
Solution Approach 1:
A guide pin is introduced as an intermediary element that penetrates the abdominal wall to provide internal stabilization. The guide pin acts as a mediator between the cutting device and the carcass, preventing destabilization forces from causing swinging while allowing the cutting operation to proceed. This intermediary structure ensures the carcass remains stable during the cutting process, enabling straight cuts from the pubic bone towards the throat.
2Stability of the object's composition
If dorsal stabilization systems are used to stabilize the carcass, then stabilization is provided for forces pushing towards the dorsal system, but forces that cause swinging de-stabilize the carcass resulting in non-straight cuts
Solution Approach 1:
Instead of stabilizing the carcass from the dorsal side, the guide pin stabilizes from the ventral side by penetrating the abdominal wall. This inverted approach provides stabilization forces that counteract swinging movements more effectively. The guide pin creates internal support that prevents the carcass from swinging during cutting, ensuring symmetrical division of the ventral part into two equal halves.
3Productivity
If the carcass is moved in a conveyor system during cutting, then transportation efficiency is improved, but it becomes difficult to stabilize the carcass during the cutting process
Solution Approach 1:
The guide pin serves as a moving intermediary that travels with the carcass through the conveyor system. As the carcass moves along the conveyor, the guide pin continuously provides internal stabilization, allowing the cutting operation to proceed accurately despite the motion. This mediator enables both efficient transportation and stable cutting to occur simultaneously.

AI summary
A method and a cutting system are provided for opening belly and breast of animal carcasses. The system includes a first cutting device capable of cutting open the belly and breast along the ventral side of an animal carcass. A guide pin is capable of being directed along the inside of the carcass abdominal wall and capable of providing a first force on the inside of the carcass belly. At least one pressure device is capable of providing a second force on the outside of the carcass belly, breast and/or neck. The pressure device is fixed or movable at least in the direction of the first and second force.
