Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If existing systems are used for laser beam detection, then basic detection function is provided, but laser beam timing and location determination accuracy is insufficient
Solution Approach 1:
The patent introduces an optical receiver as an intermediary component between the laser beam emitting device and the measurement system. The optical receiver captures the laser beam and converts it into detectable signals, enabling precise timing and location determination. This intermediary mechanism bridges the gap between basic detection and high-precision measurement requirements.
Solution Approach 2:
The patent replaces traditional mechanical measurement systems with an optical-based detection system. By using an optical receiver to detect laser beam characteristics and a processor to analyze timing and location data, the system achieves higher precision without mechanical components, thereby improving both measurement accuracy and verification reliability.
2Productivity
If basic detection methods are used, then system complexity is low, but timing and location determination efficiency is insufficient
Solution Approach 1:
The patent divides the detection system into distinct functional modules: an optical receiver for capturing laser beams, a processor for analyzing timing and location data, and associated components. This segmentation allows each module to perform its specific function efficiently, improving overall determination efficiency while keeping individual component complexity manageable.
Solution Approach 2:
The processor automatically processes the received optical signals to determine timing and location parameters without requiring external intervention for each measurement. This self-service capability enables continuous, efficient operation of the tester system, significantly improving productivity.
3Measurement precision
If no dedicated laser beam tester is used, then device complexity is low, but measurement precision for repetitive scans is insufficient
Solution Approach 1:
The laser beam tester is designed as a universal system that can handle various laser beam scanning patterns and repetition rates. The optical receiver and processor work together to provide multi-functional capabilities for timing and location determination across different scan configurations, achieving high precision measurements without requiring separate specialized equipment for each scan type.
