Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional optical spatial orientation systems use laser scanning and light sensors, then positioning accuracy can be achieved, but the system becomes large and measurement time increases
Solution Approach 1:
The patent replaces conventional mechanical/optical laser scanning systems with an electronic scanning approach using programmable controllers and coordinate transformation algorithms. The scanning apparatus uses electronic control to generate scanning patterns instead of physical laser mechanisms, significantly reducing system size while maintaining positioning accuracy through mathematical coordinate transformations between different scanning coordinate systems
Solution Approach 2:
The patent creates a universal scanning apparatus that can perform multiple scanning patterns (radial, parallel, orthogonal, spiral) using a single device through programmable control. This multi-functional capability eliminates the need for multiple specialized scanning systems, reducing overall device complexity while maintaining measurement precision across different scanning modes
2Measurement precision
If conventional optical spatial orientation systems use comprehensive scanning, then positioning accuracy is improved, but measurement time increases
Solution Approach 1:
The patent implements dynamic scanning speed adjustment where the scanning apparatus adapts its scanning rate based on the keyness of different areas. High-key areas (critical measurement zones) receive more scanning resources and slower scanning speeds for higher precision, while low-key areas use faster scanning. This dynamic allocation reduces total measurement time while maintaining positioning accuracy in critical regions
Solution Approach 2:
The patent applies partial scanning action by focusing comprehensive scanning resources on key areas that contribute most to positioning accuracy. Instead of uniformly scanning all areas with equal intensity, the system identifies and concentrates scanning efforts on critical zones, achieving acceptable positioning accuracy with reduced overall measurement time
3Productivity
If scanning speed is increased for real-time measurement, then measurement time is reduced, but positioning accuracy deteriorates
Solution Approach 1:
The patent segments the measurement space into key areas and non-key areas, allowing different scanning speeds for different segments. Critical areas maintain slower scanning speeds for high precision, while non-critical areas use faster scanning. This segmented approach enables real-time measurement capability overall while preserving positioning accuracy in segments that require it
Solution Approach 2:
The patent dynamically changes scanning parameters (speed, density, pattern) based on area keyness and measurement requirements. The system adjusts scanning velocity and sampling density as controllable parameters, slowing down in critical zones and speeding up in non-critical zones, thereby achieving real-time measurement capability while maintaining positioning accuracy where needed
