Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automatic de-boning techniques for livestock carcasses face challenges in accurately measuring the form and size of bone-in meat, leading to inefficiencies and reduced yield due to deformation caused by pressing forces during measurement.
Innovation Solution
A work measurement device with a posture holding surface, a first work presser, and a contact that moves relative to the work, allowing the contact to track the surface downstream of the presser, ensuring accurate measurement of the work's form and length without deformation interference.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a first pressing plate is held against the work to detect a trajectory for measuring the entire length of bone-in meat, then the measurement of the work form is achieved, but the first pressing plate contacts the work at a position where a second pressing plate presses the work, causing the work to be deformed by the pressing force, resulting in inaccurate measurement of the true form
Solution Approach 1:
The patent extracts the measurement function from the pressing operation by using a separate contact that only detects the work surface trajectory without applying pressing force. The contact is disposed to contact the work downstream of the first pressing plate, allowing it to track the work surface independently without being influenced by the pressing force of the first pressing plate, thereby eliminating the harmful effect of deformation on measurement accuracy
Solution Approach 2:
The contact serves as an intermediary element between the measurement system and the work. It is a separate component that indirectly detects the work form by contacting the work surface downstream, transmitting positional information without applying significant pressing force that would cause deformation. This intermediary approach allows accurate measurement while avoiding the harmful effect of work deformation
2Productivity
If multiple separate devices are used for form measurement and slit formation, then each function can be performed independently, but the device complexity increases and processing efficiency decreases
Solution Approach 1:
The patent merges the measurement function and slit formation function into a single integrated device. The contact is used for both measuring the work form by detecting its trajectory and for forming slits in the work during conveyance. This combination eliminates the need for separate measurement devices and slit forming devices, reducing device complexity and improving processing efficiency by performing both operations simultaneously in one pass
Solution Approach 2:
The contact is designed with multi-functionality, serving both as a measurement probe for detecting the work surface trajectory and as a slit forming tool. By making the contact universal for both measurement and processing tasks, the system achieves higher productivity without requiring multiple specialized devices, thereby resolving the contradiction between processing efficiency and device complexity
