Integrated Vehicle Measurement Assembly for ADAS and Wheel Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing vehicle measurement devices for ADAS calibration and four-wheel positioning are separate, requiring two devices and multiple visits to different stations, increasing cost and reducing maintenance efficiency.
Innovation Solution
A vehicle measurement device with a base module, column module, cross-beam module, and camera assembly that integrates ADAS calibration and four-wheel positioning functions, allowing a single device to perform both tasks without the need for multiple visits.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate devices are used for ADAS calibration and four-wheel positioning, then each device can perform its specific function, but the cost increases and maintenance efficiency decreases
Solution Approach 1:
The patent combines ADAS calibration function and four-wheel positioning function into a single integrated measurement device. The device includes a column module with adjustable height, a crossbeam module with mounting positions for different sensor assemblies (camera for ADAS calibration, sensors for four-wheel positioning), allowing both functions to be performed by one device, thereby reducing cost and improving maintenance efficiency
Solution Approach 2:
The measurement device is designed with multi-functionality to perform both ADAS calibration and four-wheel positioning. The column module can be adjusted to different heights, and the crossbeam module can accommodate different sensor assemblies, making the device universal for multiple vehicle maintenance tasks
2Reliability
If separate devices are used for ADAS calibration and four-wheel positioning, then each device can be optimized for its function, but the device complexity increases
Solution Approach 1:
The patent merges two separate measurement devices into one integrated device. The structure includes a base module, column module, and crossbeam module that can support both camera assemblies for ADAS calibration and sensor assemblies for four-wheel positioning, reducing system complexity while maintaining functional reliability
3Reliability
If separate devices are used for ADAS calibration and four-wheel positioning, then each device can be specialized, but the space occupation increases
Solution Approach 1:
The patent combines two separate devices into one integrated measurement device, significantly reducing the space occupied in the maintenance shop. The single device structure includes all necessary components for both ADAS calibration and four-wheel positioning functions
4Reliability
If separate devices are used for ADAS calibration and four-wheel positioning, then each device can perform its task, but the number of visits to maintenance stations increases
Solution Approach 1:
The measurement device is designed with universality to perform both ADAS calibration and four-wheel positioning at the same maintenance station. This allows the vehicle to be serviced for both functions in a single visit, reducing the time loss from multiple trips to different stations

AI summary
A vehicle measurement device includes a base module, a column module, a cross beam module, and a camera assembly. The column module includes a fixed column, a movable column assembly, and a drive assembly. The fixed column is connected to the base module. The movable column assembly is mounted on the fixed column. The movable column assembly is connected to the drive assembly. The drive assembly is used for driving the movable column assembly to lift or lower relative to the fixed column. The cross beam module is supported by the movable column assembly. The cross beam module is used for supporting a calibration element. The camera assembly is mounted on the cross beam module. The camera assembly is used for capturing wheel information of a vehicle. By means of the structure, the vehicle measurement device can not only calibrate an ADAS, but also perform four-wheel positioning.
