Bone Press with Movable Wall for Meat Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for separating meat from bones in a bone press are inefficient in terms of quantity and quality of meat harvested, as they rely on repetitive pressure applications without changing the bone arrangement, leading to suboptimal meat extraction and increased processing complexity.
Innovation Solution
The method involves placing bone parts in a pressure chamber, applying pressure to separate meat, re-orienting the bones by changing the shape of the chamber, and applying additional pressure to further extract meat, thereby enhancing meat harvesting efficiency and yield through altered bone positioning and chamber geometry.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If bone parts are pressed repeatedly in the same pressure chamber without re-orientation, then the processing complexity increases, but the meat harvesting efficiency remains suboptimal
Solution Approach 1:
The pressure chamber is designed with a movable wall that can change its shape dynamically. During the first pressing step, the chamber has an initial shape. After the first pressing, the movable wall is repositioned to change the chamber shape, which automatically re-orients the bone parts when pressure is applied in the second pressing step. This dynamic shape change eliminates the need for manual bone removal and re-positioning, thereby reducing processing complexity while improving meat harvesting efficiency.
Solution Approach 2:
The system uses the pressure chamber's own shape change mechanism to achieve bone re-orientation. The movable wall, when repositioned, automatically adjusts the bone arrangement through the application of pressure, eliminating the need for separate re-orientation equipment or manual intervention. This self-service approach simplifies the overall processing system while enhancing meat extraction efficiency.
2Productivity
If the shape of the pressure chamber is changed to re-orient bone parts, then the meat harvesting efficiency improves, but the device complexity increases
Solution Approach 1:
The pressure chamber incorporates a movable wall that can be repositioned to change the chamber's shape. This dynamic feature allows the same chamber to adapt its geometry between pressing cycles, enabling bone re-orientation without requiring multiple separate chambers or complex external repositioning mechanisms. The movable wall is actuated by a straightforward mechanism that integrates with the existing pressing system, thus improving meat harvesting efficiency while adding minimal device complexity.
3Productivity
If multiple bone presses are used to enhance meat yield, then the meat harvesting efficiency improves, but the cost and device complexity increase
Solution Approach 1:
The pressure chamber is designed to perform multiple functions within a single device. By incorporating a movable wall that can change the chamber shape, the same chamber serves both as the pressing chamber and as a bone re-orientation mechanism. This multi-functionality eliminates the need for separate bone presses or additional re-orientation equipment, thereby achieving enhanced meat harvesting efficiency without increasing the number of presses or overall device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach results in a higher yield of meat with improved quality, simplifies processing, and reduces the need for multiple bone presses, while maintaining cost-effectiveness and efficient meat collection within defined quality boundaries.
Implementation Method 1
exerting a pressure on the bone parts in the pressure chamber of 10 - 500 bar so that meat is separated from the bones
Implementation Method 2
The driving of a press-piston may be carried out in more than two phases. The piston may for example be moved from an initial position to an intermediate position, and then be retracted again to the initial position.
