Solution Overview

Problem

Existing meat separators struggle to accurately follow the complex shape of bone-in meat, leading to incomplete meat removal or residual bone in the meat product.

Innovation Solution

A meat separator with multiple clamp blocks that can displace in multiple directions and include biasing functions to elastically press against the bone surface, ensuring thorough meat separation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If a fixed clamp and movable clamp with scraping claws are used to separate meat from bone, then the meat separation function is provided, but the scraping contact portion cannot accurately track changes in the outer surface shape of the bone part, leading to incomplete meat removal or residual bone

Engineering Contradiction:
Improvetracking accuracy of scraping contact portionVSAvoidstructure complexity of clamp blocks
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The clamp block is designed with a displaceable scraping contact portion that can dynamically adjust its position in multiple directions along the outer surface of the bone part. This dynamic structure allows the scraping contact portion to accurately track changes in the bone's outer surface shape, solving the problem of incomplete meat removal while maintaining reasonable structural complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The clamp block is segmented into multiple independent components: the main body, the displaceable scraping contact portion, and the biasing function portion. This segmentation allows each component to perform its specific function independently, enabling the scraping contact portion to follow the bone's contour while the biasing portion provides elastic restoring force.

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If a single-direction clamping force is applied by the movable clamp, then the clamping mechanism is simple, but the scraping contact portion cannot be pressed accurately against the outer surface of irregularly shaped bones

Engineering Contradiction:
Improveclamping mechanism simplicityVSAvoidcontact accuracy with bone surface
Core Design Contradiction:
Ease of operationVSManufacturing precision

Solution Approach 1:

The scraping contact portion is designed to be displaceable in multiple directions rather than being fixed in a single position. This dynamic capability allows the contact portion to adapt to irregular bone shapes and maintain accurate contact without complicating the overall clamping mechanism.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The biasing function portion changes the force application parameters by providing elastic restoring force in multiple directions. This allows the scraping contact portion to be pressed against the bone surface with appropriate force while maintaining the simplicity of the clamping mechanism through passive elastic deformation.

Inventive Principle:
Principle #35Parameter changes

3Stability of the object's composition

If the scraping contact portion is made rigid to maintain structural stability, then the overall structure is stable, but the scraping contact portion cannot follow the complex outer surface shape of the bone

Engineering Contradiction:
Improvestructural stability of clamp blockVSAvoidadaptability to bone surface shape
Core Design Contradiction:
Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The clamp block is divided into a rigid main body that provides structural stability and a flexible displaceable scraping contact portion that adapts to the bone surface. This segmentation allows the rigid portion to maintain overall structural integrity while the flexible portion follows the complex outer surface shape of the bone.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The scraping contact portion is designed as a flexible component that can deform and follow the contour of the bone's outer surface. This flexible design allows the contact portion to adapt to irregular shapes while the rigid main body of the clamp block maintains structural stability.

Inventive Principle:
Principle #30Flexible shells and thin films

AI summary

A meat separator separates meat part attached to bone part by coming into contact with outer peripheral surface of the bone part of bone-in meat that moves relatively with respect to the meat separator. The meat separator includes a plurality of clamp blocks. The clamp blocks each include scraping contact portion that comes into contact with the outer peripheral surface of the bone part, and the scraping contact portions cooperate with each other so as to clamp the outer peripheral surface of the bone part. At least one of the clamp blocks is configured so that at least a part of the scraping contact portion of the clamp block is displaceable in a plurality of directions along outer surface shape of the bone part, and the at least one of the clamp blocks includes biasing function portion that elastically pushes back the displacement in direction moving away from bone part.
