Truck Wheel Blocking Device with V-Shaped Folding Arms
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wheel blocking devices for trucks at loading and unloading platforms are difficult to mount and maintain, especially in dirty or icy conditions, and often leave residue, which can lead to safety issues and operational inefficiencies.
Innovation Solution
A device with a guide system featuring a road side axle, middle axle, and façade side axle connected by rotatable arms that fold into a V-shape, with movable wagons and drive mechanisms to automatically position the wheel locking means, allowing for easy deployment and minimizing dirt accumulation by design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the wheel blocking device is incorporated in the positioning place, then the blocking function is provided, but dirt and such like become difficult to remove from the positioning place
Solution Approach 1:
The wheel blocking device is extracted from the positioning place and mounted on the side of the guide instead. The guide structure extends alongside the positioning place, allowing the blocking mechanism to operate independently from the main positioning surface, thus preventing dirt accumulation issues while maintaining the blocking function.
Solution Approach 2:
The blocking device is repositioned from a two-dimensional plane (incorporated in the positioning place) to a three-dimensional arrangement (mounted on the side of the guide). This spatial relocation allows the blocking function to be performed while keeping the positioning place surface clear and accessible for cleaning.
2Reliability
If the wheel blocking device is built into the driveway, then the blocking function is provided, but difficulties occur during snow and ice formation
Solution Approach 1:
The blocking device is extracted from the driveway surface and mounted on the side of the guide structure. This removes the blocking mechanism from direct contact with snow and ice accumulation areas, preventing the harmful effects of frozen conditions while maintaining blocking capability.
Solution Approach 2:
Instead of building the blocking device into the driveway (embedded approach), the device is mounted on the side of the guide (external approach). This inverted mounting strategy prevents snow and ice from interfering with the blocking mechanism's operation.
3Ease of operation
If the wheel locking means is folded out sideward, then the positioning is facilitated and dirt accumulation is minimized, but the structure becomes more complex
Solution Approach 1:
The blocking arms are designed to be rotatable and foldable rather than fixed. The arms can rotate between a folded position (parallel to the guide) and an extended position (perpendicular to the guide), providing dynamic adaptability that simplifies operation while managing structural complexity through functional movement.
Solution Approach 2:
The blocking arms can be folded back alongside the guide structure when not in use, creating a compact nested configuration. This nesting capability reduces the overall spatial footprint and simplifies the operational state while maintaining the full blocking function when extended.

AI summary
Device for the locking of the wheel of a truck with a guide (2) extending from a road side to a façade side with a first wagon (12) moveable therein with a road side axle (7) and road side arm (10), and with a second wagon (13) with a façade side axle (9) and a façade side arm (11), with in between the façade side arm (11) and the road side arm (10) a middle axle (8), whereby the arms (10,11), from a first position, in which the arms (10,11) lie in a substantially straight line, can be folded outwards to a second position, in which the arms (10,11) relative to each other take up a V-shaped form for the blocking of the wheel of the truck.
