Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional headlamp alignment methods are used, then the alignment process can be completed, but it is time-consuming and prone to human error and computer processing inaccuracies
Solution Approach 1:
The patent replaces conventional mechanical alignment methods with a laser-based optical alignment system. The laser alignment light source projects a beam pattern that directly indicates alignment status, eliminating the need for time-consuming mechanical adjustments and computer processing, thereby improving both accuracy and reducing time loss.
Solution Approach 2:
The patent introduces a laser alignment light source as an intermediary tool between the headlamp and the alignment target. This intermediary projects a visible beam pattern that serves as a direct reference for alignment, eliminating the need for complex computer processing and reducing human error while maintaining high precision.
2Reliability
If conventional headlamp alignment methods are used, then the alignment can be performed, but the quality of alignment is subject to computer processing and human error
Solution Approach 1:
The patent replaces complex computer processing systems with a simple laser-based optical alignment system. The laser alignment light source provides direct visual feedback through its beam pattern, eliminating reliance on computer processing and human judgment, thereby improving reliability while reducing system complexity.
Solution Approach 2:
The laser alignment light source serves itself by projecting a self-contained beam pattern that inherently indicates alignment status. The system requires no external computer processing or human interpretation - the beam pattern itself provides the alignment information, improving reliability through self-sufficiency.
