Engineering Contradiction Analysis
1Reliability
If conventional methods for aligning calibration devices are used, then alignment can be achieved, but the process becomes complex and error-prone
Solution Approach 1:
The patent introduces an auxiliary target as an intermediary element between the calibration device and the vehicle. This auxiliary target includes alignment marks that simplify the alignment process by providing clear visual references, thereby reducing complexity while maintaining or improving alignment accuracy.
Solution Approach 2:
The patent replaces complex mechanical alignment procedures with an optical alignment system using laser emitters and visual alignment marks. This substitution eliminates the need for complex mechanical measurements and calculations, reducing process complexity while enhancing reliability.
