Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If manual adjustment mechanisms are used for sensor calibration, then the sensor can be positioned to achieve correct inclination, but the process becomes time-consuming and expensive
Solution Approach 1:
The patent replaces manual mechanical adjustment mechanisms with a visual alignment system using laser projection. The laser projects reference lines that the sensor can be aligned to visually, eliminating the need for time-consuming manual measurement and adjustment while maintaining positioning precision.
Solution Approach 2:
The patent creates a visual copy or representation of the correct sensor orientation through laser-projected reference lines. Instead of directly measuring and adjusting the sensor angle, the system projects a visual template that guides the alignment process, making calibration faster and more intuitive.
2Measurement precision
If manual adjustment mechanisms are used for sensor calibration, then the sensor can be positioned to achieve correct inclination, but the cost increases
Solution Approach 1:
The patent replaces expensive manual calibration equipment and processes with a simpler laser-based visual alignment system. This substitution reduces calibration costs while maintaining or improving positioning precision through objective visual references.
Solution Approach 2:
The use of projected visual references creates a reproducible alignment template that can be used consistently across different calibration scenarios, reducing the need for expensive specialized equipment and expert manual intervention.
3Ease of operation
If the sensor system is fixed for different vehicular setups, then installation is simplified, but adaptability to various vehicle configurations is reduced
Solution Approach 1:
The patent creates a universal calibration system using laser projection that can accommodate different vehicle types and sensor configurations. The visual reference lines provide a common alignment methodology that works across multiple applications, making the installation process easier while maintaining adaptability.
Solution Approach 2:
The system allows dynamic adjustment of sensor position guided by visual references, enabling adaptation to different vehicle configurations while maintaining a consistent and simple installation process. The laser projection can be adjusted to match various mounting scenarios.
