Solution Overview
Problem
Existing transport vehicles struggle to accurately grip containers with multiple grip sections due to positioning inaccuracies, necessitating improved alignment mechanisms.
Innovation Solution
A transport vehicle equipped with a gripping device and elevation device, featuring guide bodies that correct positioning relative to multiple grip sections through contact during the lowering operation, ensuring precise alignment and grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a gripping device is used to grip a container with multiple grip sections, then the container can be transported, but the positioning accuracy and alignment of the gripping device relative to the container become challenging due to potential deviations
Solution Approach 1:
The patent introduces guide bodies as intermediary elements between the gripping device and the container. These guide bodies include guide surfaces that contact the grip sections during the lowering operation, serving as mediators to correct positioning deviations. The guide bodies translate positional deviations into corrective motions, enabling accurate alignment without requiring extremely precise initial positioning of the gripping device.
Solution Approach 2:
The guide bodies perform preliminary positioning action during the lowering operation before the actual gripping occurs. As the gripping device approaches the container, the guide surfaces already begin to correct positional deviations by contacting the grip sections and guiding the gripping device into proper alignment. This preliminary correction ensures that by the time gripping forces are applied, the positioning accuracy is already established.
2Ease of operation
If the gripping device is lowered to grip the container, then the gripping operation can be performed, but position and angle deviations may prevent accurate gripping
Solution Approach 1:
The guide surfaces act as intermediaries that convert rough positioning into precise alignment during the lowering operation. They contact the grip sections and provide mechanical guidance that corrects both position and angle deviations, enabling accurate gripping even when initial positioning is imperfect.
Solution Approach 2:
The system uses the container's own grip sections as part of the positioning mechanism. The guide surfaces contact these existing features to correct positioning, and the same grip sections are then used for gripping. The container essentially helps position itself for gripping through the interaction with the guide surfaces during lowering.
3Adaptability or versatility
If multiple grip sections are present on the container, then gripping options increase, but the requirement for accurate positioning and alignment becomes more stringent
Solution Approach 1:
The guide bodies serve multiple functions: they guide positioning, correct angular deviations, and work with any of the multiple grip sections on the container. The same guiding mechanism accommodates different container types and grip section configurations, providing universal adaptability without sacrificing positioning accuracy.

AI summary
A first guide body includes a pair of first guide surfaces and corrects the position in a second direction of a gripping body section relative to a first grip section by at least one of the pair of first guide surfaces coming into contact with the first grip section during a lowering operation for gripping. A second guide body includes a pair of second guide surfaces and corrects the position in the second direction of the gripping body section relative to a target grip section by at least one of the pair of second guide surfaces coming into contact with the target grip section during the lowering operation for gripping. The first guide body and the second guide body are spaced apart from each other in at least either a first direction or the second direction.
