Tugger Train Trailer Lifting Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Tugger train trailers with lifting devices require multiple space-consuming operating elements for lifting, lowering, and securing trolleys, which complicates their compact design and ergonomics.
Innovation Solution
Integration of a mechanical lock that automatically raises or lowers the trailer when the trolley is secured or unlocked, eliminating the need for separate operating elements by coupling the locking mechanism with the lifting device, and using a spring-loaded snap hook or cam to secure the trolley in place.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If multiple separate operating elements are provided for lifting, lowering, and securing the trolley, then the functionality is complete, but the device complexity and space requirements increase
Solution Approach 1:
The patent combines multiple operating elements into a single integrated control mechanism. The operating element simultaneously controls the lifting device and the locking mechanism, eliminating the need for separate controls for each function. This merging reduces the number of operating elements while maintaining complete functionality for lifting, lowering, and securing the trolley.
Solution Approach 2:
The single operating element is designed to perform multiple functions: it activates the lifting device to raise or lower the trolley and simultaneously controls the locking mechanism to secure or release the trolley. This multi-functional design allows one element to replace what would traditionally require multiple separate controls.
2Area of stationary object
If the trailer is made compact to minimize space, then the space efficiency improves, but the area available for operating elements is reduced
Solution Approach 1:
By merging the lifting and locking controls into a single operating element, the patent reduces the total space required for controls on the trailer. This allows the trailer to be made more compact while still providing complete functionality, as fewer separate controls are needed to occupy space on the trailer structure.
3Adaptability or versatility
If separate operating elements are used for locking and lifting, then each function can be controlled independently, but the number of operating elements increases
Solution Approach 1:
The patent merges the control functions for locking and lifting into a single operating element that can be actuated in different ways to achieve different functions. The operating element is coupled to both the lifting device and the locking mechanism, allowing one element to control multiple functions through its actuation state.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This solution reduces the number of required operating elements, enhances ergonomics, and simplifies the operation by automatically adjusting the trailer's position based on the trolley's locking state, allowing for efficient and space-saving control of the tugger train trailer.

AI summary
The invention relates to a tugger train trailer (10) with a lifting device that adjusts the tugger train trailer between a lowered receiving position for a trolley (20) and a raised transport position for the trolley, wherein a locking mechanism for the trolley is provided that secures the trolley in the transport position on the tugger train trailer, wherein the locking mechanism interacts with an actuating switch for the lifting device such that when the trolley is locked, the actuating switch for the lifting device is actuated to raise the trolley.
