Roller Tire Inspection Stopper for Pit-Free Wheel Restraint
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle inspection devices lack a fixing mechanism to stop tire rotation and require a pit for installation, limiting flexibility in inspection location and necessitating external devices for unloading wheels.
Innovation Solution
A vehicle inspection device with rollers that allow tire idling, featuring a stopper mechanism to halt tire rotation and a link system for elevation, along with movement rollers and a side roller for stability, enabling installation on a flat surface without a pit and allowing self-propelled vehicle loading and unloading.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a fixing mechanism (brake mechanism) and wheel stopping mechanism are added to prevent wheel idling, then wheel stability is improved, but device complexity increases
Solution Approach 1:
The stopper mechanism is integrated into the existing roller support structure, combining the wheel stopping function with the roller housing. The link mechanism that elevates the stopper is coupled with the roller support frame, merging multiple functions into a unified structure rather than adding separate independent systems.
Solution Approach 2:
The stopper mechanism automatically engages with the wheel flange through gravitational force when the link mechanism elevates it, eliminating the need for additional actuators or complex control systems. The mechanism uses the wheel's own position and the stopper's weight to achieve reliable engagement without external power sources.
2Ease of manufacture
If a pit is formed on the floor for installing the elevation device, then the elevation mechanism can be disposed, but flexibility in selecting inspection location is reduced
Solution Approach 1:
The elevation mechanism is repositioned from a floor-based pit installation to a vertical arrangement within the roller support housing. The link mechanism operates in the vertical dimension, elevating the stopper upward from the housing interior, which eliminates the need for horizontal floor excavation while maintaining the elevation function.
Solution Approach 2:
The roller support housing serves multiple functions: it supports the rollers, contains the stopper mechanism, and provides structural mounting for the link mechanism. This multi-functional design allows the entire elevation system to be self-contained within the housing, making the inspection device portable and adaptable to various locations without floor modifications.
3Ease of operation
If an incidental device such as a winch is used to exert force on the vehicle for unloading the wheel, then wheel unloading is enabled, but device complexity and external dependencies increase
Solution Approach 1:
The stopper mechanism automatically returns to its initial position after the wheel is unloaded, ready for the next operation. The link mechanism can be manually or automatically reset without requiring external assistance, making the entire system self-contained and eliminating dependency on external unloading devices.

AI summary
A vehicle inspection device for an inspection implemented with a tire of a vehicle idling includes a tire supporter. The tire supporter includes rollers structured to allow the tire to idle; a housing supporting the rollers so as to allow the rollers to rotate; a stopper contained in the housing and structured to move up and down and butt into the tire disposed on the rollers; and a link mechanism structured to elevate the stopper. The vehicle inspection device is structured to be disposed on a plane that allows the vehicle to run thereon.
