Solution Overview
Problem
Existing optical measurement and calibration systems for vehicle components, particularly the chassis, face challenges in accurately determining and transmitting the parameters of optical measuring mark patterns due to potential transmission errors and the need for precise alignment of measuring plates with measuring heads.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If measuring plate parameters are manually transmitted to measuring heads, then flexibility in handling is improved, but transmission errors occur and reliability deteriorates
Solution Approach 1:
The patent uses an optically detectable information carrier (such as a barcode or QR code) on the measuring plate to create an optical copy of the parameter data. This allows the measuring head to automatically read and transmit parameters without manual intervention, eliminating transmission errors while maintaining operational flexibility through automated recognition.
Solution Approach 2:
The patent replaces manual mechanical transmission of parameters with an optical information carrier system. The measuring head uses its image recording device to optically detect and read the information carrier, substituting the mechanical manual transfer process with an automated optical reading mechanism that ensures reliable data transmission.
2Ease of operation
If information carrier is placed on front side of measuring panel, then easy access for reading is improved, but optical features and measurement mark pattern are impaired
Solution Approach 1:
The patent divides the measuring plate into distinct functional zones: the front side contains optical features and measurement mark patterns for measurement, while the rear side contains the optically detectable information carrier for data storage. This spatial segmentation allows both functions to operate independently without interference, maintaining measurement precision while enabling easy information access.
Solution Approach 2:
The patent moves the information carrier from the front side (2D plane of measurement) to the rear side (opposite face), utilizing the third dimension (depth/thickness) of the measuring plate. This dimensional relocation allows the information carrier to be accessed without compromising the optical features on the front side, as the camera can easily capture the rear-side information when the plate is positioned for measurement.
3Quantity of substance
If measuring plate surface area is enlarged to accommodate information carrier, then information storage capacity is improved, but device complexity and manufacturing difficulty increase
Solution Approach 1:
Instead of expanding the front surface area to accommodate the information carrier, the patent inverts the approach by placing the information carrier on the rear side of the measuring plate. This inversion allows the front surface to remain dedicated to optical features while the rear surface provides the necessary space for the information carrier, avoiding increased device complexity and manufacturing difficulty.
