Bone-Meat Separation Apparatus with V-Guide Stabilization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bone-meat separation devices face issues with positional shifts and oscillations of the femoral head, leading to reduced meat yield and failure to separate valuable oyster meat during the deboning process of bone-in limb meats.
Innovation Solution
A bone-meat separation device with a V-shaped guide space and a cutter positioned downstream, along with a holding portion to stabilize the meat part, ensures accurate cutting by suppressing oscillation and positional shifts, and includes movable guide members and a plate-like cutter with an arc-like blade edge for improved cutting efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the bone-in limb meat is guided to the Y-shaped guide space and positioned by abutting on the Y-shaped derivation guide, then the automation of the cutting process is achieved, but the cutting position shifts due to oscillation of the femoral head or positional shift of the femoral head running on the guide
Solution Approach 1:
The V-shaped guide space is designed to preliminarily position and constrain the bone-in limb meat before cutting occurs. The guide space pre-establishes the correct cutting position by guiding the bone-in limb meat into a predetermined orientation, ensuring that the femoral head is properly aligned with the cutter before the cutting action takes place.
Solution Approach 2:
The V-shaped guide space acts as an intermediary element between the conveying mechanism and the cutter. It mediates the positioning of the bone-in limb meat, translating the conveying motion into a stable, pre-positioned state that is ready for accurate cutting, thereby reducing oscillation and positional shifts.
2Device complexity
If the femoral head runs on the Y-shaped derivation guide without additional support, then the structure remains simple, but oscillation of the femoral head causes cutting position shifts and reduces meat yield
Solution Approach 1:
The V-shaped guide space preliminarily stabilizes the bone-in limb meat and femoral head before cutting by constraining their movement. This preliminary positioning action prevents oscillation during the cutting process, ensuring that the cutting position remains accurate and maximizing meat yield without requiring complex additional support structures.
3Extent of automation
If the cutter is positioned at the downstream end of the guide space, then the cutting process is automated, but oyster meat adhering to the vicinity of the femoral head remains unseparated
Solution Approach 1:
The V-shaped guide space performs a preliminary separation function by guiding and positioning the bone-in limb meat in a way that exposes both the main meat part and the oyster meat to the cutter. The guide space pre-positions the specimen so that the cutter can effectively separate both types of meat from the femoral head in a single automated cutting action.

AI summary
A bone-meat separation device for a bone-in limb meat according to an embodiment is a bone-meat separation device for a bone-in limb meat for separating a meat part adhering to a trunk-side end bone head of a bone-in limb meat, the device including a plurality of clamp portions for conveying the bone-in limb meat along a conveying path, a guide portion disposed on the conveying path and forming a V-shaped guide space with an open end thereof being directed upstream in a conveying direction of the bone-in limb meat, a cutter disposed at a downstream end of the guide space in the conveying direction, and a holding portion holding the meat part below the guide portion and the cutter. The holding portion is configured to hold the meat part of the bone-in limb meat when the meat part is cut from the trunk-side end bone head with the cutter.
