Blade Mount Decentralized Fastening for Food Slicing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional blade fastening systems for food slicing machines are prone to incorrect assembly and high risk of failure due to reliance on a single central screw connection, which can lead to uncontrolled release of the blade.
Innovation Solution
A decentralized multi-point screw connection system with torque transmission elements that serve both force transmission and fastening, ensuring secure attachment of the blade to the blade mount through multiple points, reducing the risk of incorrect assembly and enhancing stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a single central screw connection is used for blade fastening, then the device complexity is reduced, but the reliability of blade attachment deteriorates due to high stress concentration and risk of failure
Solution Approach 1:
The patent divides the single central fastening point into multiple decentralized fastening points distributed around the blade periphery. Each torque transmission element with its associated receiver creates an independent fastening location, distributing the mechanical load and eliminating the stress concentration inherent in single-point fastening systems.
Solution Approach 2:
The invention transitions from a one-dimensional central fastening approach to a two-dimensional distributed fastening pattern around the blade circumference. The torque transmission elements are arranged radially outward from the center, creating a circular distribution pattern that leverages the rotational symmetry of the blade mounting interface.
2Reliability
If a decentralized multi-point screw connection is used, then the reliability of blade attachment is improved, but the device complexity increases due to multiple fastening components
Solution Approach 1:
The patent combines the torque transmission function and the fastening function into a single integrated torque transmission element. This element simultaneously transmits rotational torque from the blade to the drive mechanism and provides the fastening interface through its engagement with the receiver, eliminating the need for separate torque transmission and fastening components.
Solution Approach 2:
The torque transmission element serves multiple functions: it transmits torque, provides a fastening interface for the receiver, and distributes mechanical loads across multiple mounting points. This multi-functionality reduces the overall component count despite the decentralized multi-point fastening approach.
3Ease of manufacture
If force transmission and shape matching are separated into different components, then the ease of manufacture is improved, but the reliability deteriorates due to potential incorrect assembly and lack of coordination between components
Solution Approach 1:
The patent merges the force transmission function and shape matching function into the same torque transmission element. The element's geometry is designed to provide both the mechanical interface for force transmission and the shape-complementary interface for shape matching, ensuring that both functions occur at the same location and are inherently coordinated.
Solution Approach 2:
The torque transmission element and receiver are designed with complementary geometries that automatically ensure correct alignment and coordination during assembly. The shape-matched connection inherently guides the force-transmitting connection into proper position, eliminating the need for separate alignment procedures or complex assembly sequences.

AI summary
A blade mount for a cutting machine, in particular for a food slicing machine, includes a contact surface for a blade, a mount section for the blade projecting axially from the contact surface and at least one torque transmission element which projects axially from the contact surface, which is radially spaced apart from the mount section, which engages into the blade and in which a mount is formed for fastening the blade to the blade mount. Additionally, a blade is matched thereto, to a handling apparatus for assembling the blade at the blade mount, and to a system of blade mount, blade and handling apparatus.
