Mincing Machine Support Cross With Assembly Lugs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing assembly and disassembly processes for knife pins in meat grinders are complex and require additional tools, making them cumbersome and inefficient.
Innovation Solution
A support cross with lugs on the hub that can engage with recesses or notches on the fastening ring, allowing for rotational movement to loosen the screw connection without additional tools, serving as both a structural element and a tool for assembly and disassembly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional tools are used to loosen the screw connection during assembly and disassembly, then the screw connection can be securely fastened, but the assembly and disassembly process becomes more complex and requires more tools
Solution Approach 1:
The support cross is designed with lugs that serve dual purposes: it functions as both a structural support element and a tool for assembly and disassembly operations. The lugs engage with recesses in the fastening ring to enable rotational movement for loosening the screw connection, eliminating the need for separate tools while maintaining secure fastening capability.
2Reliability
If additional tools are required for assembly and disassembly operations, then the screw connection can be properly secured, but the ease of operation is reduced
Solution Approach 1:
The support cross performs self-service by incorporating lugs that enable it to function as both a structural component and an assembly tool. The lugs engage with the fastening ring recesses to provide rotational movement for loosening, allowing the support cross to assist in its own assembly and disassembly without requiring external tools.
3Ease of operation
If the support cross is designed with lugs for tool function, then assembly and disassembly is simplified, but the device complexity increases
Solution Approach 1:
The lugs are integrated directly into the support cross structure, merging the structural support function with the assembly tool function into a single component. This integration simplifies the overall device by eliminating the need for separate assembly tools while adding minimal complexity to the support cross design itself.

AI summary
The invention relates to a cross-shaped support (10) for a meat-mincing machine. The cross-shaped support (10) has a hub (11) with a central bore (15), an outer ring (13), and multiple webs (12) which extend between the hub (11) and the outer ring (13). A groove (14) is provided on the exterior of the outer ring (13) in order to support the cross-shaped support (10) in the meat-mincing machine in a rotationally fixed manner. The cross-shaped support (10) additionally functions as a tool, for example the cross-shaped support has projections (16) which allow a simplification of the assembly or disassembly of the knife pin from the meat-mincing machine (Fig. 1).
