Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple elements (light source, scanning unit, image acquisition unit) are individually optimized, then measurement conditions can be optimized, but device complexity and ease of operation deteriorate
Solution Approach 1:
The patent combines the optimization of multiple elements (light source, scanning unit, image acquisition unit) into a unified measurement sensitivity parameter. By merging these separate optimization tasks into a single composite parameter, the system achieves optimized measurement conditions while reducing the complexity of individual element adjustments.
Solution Approach 2:
The patent introduces a new parameter 'measurement sensitivity' defined as the product of light amount and scanning speed. This parameter change allows the system to optimize measurement conditions through a single parameter rather than adjusting multiple elements independently, thereby reducing setting complexity.
2Measurement precision
If scanning speed and light amount are independently adjusted, then measurement sensitivity can be optimized, but ease of operation deteriorates
Solution Approach 1:
The patent defines measurement sensitivity as a composite parameter equal to the product of light amount and scanning speed. By expressing the optimization requirement in terms of this single composite parameter rather than two independent parameters, the system maintains optimized measurement sensitivity while significantly improving ease of operation.
Solution Approach 2:
The system automatically determines the appropriate light amount and scanning speed combinations based on the selected measurement sensitivity level. This self-service approach eliminates the need for users to manually coordinate multiple parameters, thereby improving ease of operation while maintaining measurement optimization.
