Transport Cart with Rotating Loading Trough for Contact-Free Carcass Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport carts require significant muscle power to load and unload objects or animal carcasses, especially due to the need for direct contact with the goods, which is hygienically problematic and inefficient, particularly in applications like agriculture where carcass handling is involved.
Innovation Solution
A transport cart equipped with a loading trough featuring a rotatable loading and/or unloading apparatus at its front end, which can be driven by motors for controlled rotation, allowing for automated loading and unloading without operator contact, and includes features like rollers, serrated strips, and a trailer for operator convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If a rope winch is used to pull animal carcasses onto the handcart, then the loading process is automated, but significant muscle power is still required and operator contact with the carcass is necessary
Solution Approach 1:
The patent introduces a loading trough as an intermediary structure between the operator and the animal carcass. The carcass is loaded into the trough through the front end, allowing the operator to remain at a distance while still achieving automated loading via the rope winch mechanism. This intermediary structure eliminates direct operator contact with the carcass while maintaining loading automation.
2Device complexity
If manual muscle power is used to push the support under the transported goods, then the transport cart can be operated simply, but significant muscle power is required which reduces operational efficiency
Solution Approach 1:
The patent implements a self-service loading mechanism where the loading trough with its rotatable loading apparatus automatically performs the loading function. The trough can be rotated to position itself for loading, and the loading apparatus can be rotated to engage with the carcass, eliminating the need for manual muscle power to push supports under goods while maintaining relatively simple cart structure.
3Ease of operation
If the loading trough bottom has a rotatable loading apparatus, then contact-free loading is achieved, but the device complexity increases
Solution Approach 1:
The loading apparatus integrated into the loading trough bottom serves multiple functions: it can rotate in both directions to position itself for loading, it can engage with the carcass through its rotatable action, and it works in conjunction with the trough rotation mechanism. This multi-functionality achieves contact-free loading while minimizing the addition of separate complex components.

AI summary
A transport cart and a method using a transport cart transports objects or animal carcasses. The transport cart has a loading trough which has a region which is arranged on a side of the loading trough facing away from a handlebar and/or from at least one handle, wherein the region has at least one loading and/or unloading device, thus making loading and/or unloading possible such that the object which is to be transported or the transported object or the animal carcass which is to be transported or the transported animal carcass does not have to be touched by an operator.
