Transport Trolley C-Shaped Support Elements Roller Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transport trolleys with rollers directly on the underside of the support plate face issues with damage during forklift pickup, reduced stability, and limited ground clearance, making them unsuitable for use with tugger train trailers and autonomous transport vehicles.
Innovation Solution
The transport trolley features C-shaped support elements with vertically arranged support beams that allow rollers to be positioned outward for increased stability and create space for tugger train trailer support strips to lift the trolley, while also providing sufficient ground clearance for autonomous vehicles to drive under and lift the trolley.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If rollers are arranged directly on the underside of the support plate, then the structure is simple, but the rollers are damaged when picked up by forklift and ground clearance is reduced
Solution Approach 1:
The support structure is segmented into support elements with support beams that are spaced inwards from the outer edges of the support frame. This segmentation allows rollers to be positioned on these support elements rather than directly on the support plate, creating protected zones that prevent forklift forks from contacting the rollers during pickup operations.
2Reliability
If rollers are placed further inwards on the support frame, then roller protection is improved, but stability of the transport trolley is reduced
Solution Approach 1:
The support elements extend vertically downwards from the support frame, creating a three-dimensional structure. This vertical dimension allows the rollers to be positioned outwardly on the support elements while the support beams are spaced inwards, thus maintaining both roller protection and trolley stability simultaneously by utilizing spatial arrangement in multiple dimensions.
3Adaptability or versatility
If ground clearance is increased, then autonomous vehicles can drive under, but the structure becomes more complex
Solution Approach 1:
The support elements with vertically extending support beams serve multiple functions: they increase ground clearance to allow autonomous vehicles to drive under the support frame, they provide structured zones for roller placement, and they maintain structural integrity. This multi-functional design achieves versatility without proportionally increasing complexity.

AI summary
The invention relates to a transport trolley (1) for transporting and storing goods, which has a rectangular support frame (2) on the underside of which a roller (7a-7d) is arranged at each of the four corner areas, with which the transport trolley (1) is supported on a roadway. Vertically downward extending support elements (10a; 10b; 10c; 10d) are arranged on the support frame (2), to which the rollers (7a; 7b; 7c; 7d) are attached, the support elements (10a; 10b; 10c; 10d) being arranged at the corner regions of the support frame (2) and the support elements (10a; 10b; 10c; 10d) each having at least one vertically downward extending support beam (11a, 11b; 11c) arranged in the corner region of the support frame (2) spaced inwards from at least one outer edge (AK, LK, SK) of the support frame (2).
