Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate ADAS calibration device and four-wheel positioning device are used, then each device can perform its specific function, but the cost increases and maintenance efficiency decreases
Solution Approach 1:
The patent combines the ADAS calibration device and four-wheel positioning device into a single integrated vehicle measurement device. The device includes a column assembly with a camera assembly for ADAS calibration and a wheel assembly for four-wheel positioning, allowing both functions to be performed at one workstation, thereby improving maintenance efficiency while maintaining calibration accuracy
Solution Approach 2:
The integrated device is designed to perform multiple functions: it can conduct ADAS sensor calibration using the camera assembly and同时进行four-wheel positioning using the wheel assembly. The column assembly can be adjusted to accommodate different vehicle models and types, making the device universally applicable for various calibration and positioning tasks
2Reliability
If two separate devices are purchased for ADAS calibration and four-wheel positioning, then each function can be performed independently, but the cost increases
Solution Approach 1:
The patent merges the functionality of two separate devices (ADAS calibration device and four-wheel positioning device) into one integrated vehicle measurement device. The device includes a column assembly with camera assembly for ADAS calibration and wheel assembly for four-wheel positioning, reducing the quantity of devices from two to one while maintaining the accuracy of both calibration functions
Solution Approach 2:
The integrated device is designed with universal functionality to perform both ADAS calibration and four-wheel positioning. The column assembly can be adjusted for different vehicle models, and the device can switch between calibration modes and positioning modes, eliminating the need to purchase separate specialized devices
3Reliability
If two separate work stations are used for ADAS calibration and four-wheel positioning, then each calibration can be performed with dedicated equipment, but the space occupied increases and convenience decreases
Solution Approach 1:
The patent combines the ADAS calibration workstation and four-wheel positioning workstation into a single integrated workstation. The device includes a column assembly with camera assembly for ADAS calibration and wheel assembly for four-wheel positioning, allowing both functions to be performed at one location, thereby reducing the total space occupied and improving convenience
Solution Approach 2:
The integrated workstation is designed to handle multiple calibration and positioning tasks in one location. The column assembly can be adjusted to accommodate different vehicle models and types, and the device can switch between calibration modes and positioning modes, eliminating the need for separate dedicated workstations and reducing overall space requirements
4Adaptability or versatility
If the device structure is made adjustable for different vehicle models, then the adaptability increases, but the device complexity increases
Solution Approach 1:
The patent employs dynamic adjustment mechanisms to enable the device to adapt to different vehicle models. The column assembly includes height adjustment and angle adjustment mechanisms that allow the camera assembly and wheel assembly to be repositioned according to different vehicle dimensions and configurations, providing versatility without requiring multiple fixed-configuration devices
Solution Approach 2:
The device is divided into modular components including a column assembly, camera assembly, and wheel assembly that can be independently adjusted. This segmentation allows each component to be optimized for specific functions while maintaining overall adaptability, reducing the complexity burden by organizing adjustments into discrete, manageable modules

AI summary
Disclosed in the present invention are a vehicle measurement device and a vehicle calibration method. The 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, so that it is unnecessary to purchase two devices, and the cost is reduced. At the same time, the vehicle does not need to be moved to two stations for maintenance, so that the maintenance efficiency is improved, and the device is more convenient to use.
