Solution Overview
Problem
Existing devices for processing slaughter animals face challenges with overload protection mechanisms that are difficult to clean, prone to corrosion, and negatively impact hygiene due to the accumulation of dirt and bacteria, leading to potential device damage.
Innovation Solution
The implementation of a magnetic connection system between transfer and driven elements, which breaks under overload, eliminating the need for balls, springs, and ball chambers, thereby reducing bacterial settlement and corrosion risks, and allowing for a more compact and cost-effective design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional overload protection means with balls, springs and ball chambers are used, then overload protection is achieved, but hygiene properties deteriorate due to difficult cleaning and corrosion
Solution Approach 1:
The patent replaces the traditional mechanical overload protection system (balls, springs, ball chambers) with a magnetic coupling system. The magnetic coupling consists of a drive element with magnetic drive means and a driven element with magnetic coupling means, eliminating complex mechanical components that are difficult to clean and prone to corrosion. This substitution maintains overload protection functionality while significantly improving hygiene properties.
Solution Approach 2:
The invention extracts and removes the problematic mechanical components (balls, springs, ball chambers) from the overload protection mechanism, retaining only the essential function of overload protection through a simplified magnetic coupling system. This extraction eliminates the sources of hygiene problems while preserving the core protective function.
2Object-affected harmful factors
If magnetic connection system is used, then hygiene properties improve by reducing surfaces for bacterial growth, but device complexity changes from mechanical to magnetic system
Solution Approach 1:
The patent substitutes mechanical complexity with magnetic field-based coupling. The magnetic drive means and magnetic coupling means create a simplified system with fewer moving parts and no complex mechanical assemblies. While the physics changes from mechanical to magnetic, the overall device complexity is reduced due to elimination of multiple mechanical components.
Solution Approach 2:
The invention merges the drive element and driven element into a closely coupled magnetic system where the magnetic field acts as the direct transmission medium. This merging eliminates intermediate mechanical components and creates a more integrated, simpler system architecture.

Function Achieved in This Case
This solution enhances hygiene by minimizing surfaces for bacterial growth, reduces corrosion, and ensures reliable operation by preventing damage during overload situations, while maintaining efficient processing operations.
Implementation Method 1
the first connecting element is configured as a first magnet element and the second connecting element is either magnetisable or configured as a second magnet element, wherein the first and the second connecting element are configured to cooperate such that the rigid connection between the element to be driven and the transfer element is effected via a magnetic connection between the first connecting element and the second connecting element during normal operation
Implementation Method 2
in an overload situation the magnetic connection between the first connecting element and the second connecting element is broken on account of the overload

AI summary
The invention provides a device and a method for processing slaughter animals, in particular slaughtered poultry such as chickens, and/or parts thereof. The device comprises a driving system for driving an element to be driven of the device. The, driving system comprises a driving element, a transfer element, which is driven by the driving element in use and which is rigidly connected during normal operation to the element to be driven, as well as overload protection means which are configured to rigidly connect the processing element and the transfer element during normal operation and to allow relative movement between the processing element and the transfer element in an overload situation if a force that acts between the processing element and the transfer element exceeds a threshold value. The overload protection means comprise a first connecting element forming part of one of the transfer element and the element to be driven and a second connecting element forming part of the other one of the transfer element and the element to be driven, wherein the first connecting element is configured as a first magnet element (36) and the second connecting element is either magnetisable or configured as a second magnet element.
