Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If light irradiation position and light detection position are measured using measurement means, then measurement precision is improved, but device complexity and cost increase
Solution Approach 1:
The patent extracts the measurement function from specialized measurement means and integrates it into the probe structure itself. The probe includes light irradiation position detection means and light detection position detection means that are built-in, eliminating the need for separate measurement devices and reducing overall system complexity while maintaining positioning accuracy.
Solution Approach 2:
The probe performs self-positioning by detecting its own light irradiation position and light detection position through integrated detection means. This self-service capability eliminates the need for external measurement operations, reducing both device complexity and the time/effort required for positioning.
2Measurement precision
If light irradiation position and light detection position are measured manually, then measurement precision is improved, but loss of time and effort increase
Solution Approach 1:
The probe automatically detects and records its own light irradiation position and light detection position through integrated detection means, eliminating the need for manual measurement operations. This self-positioning capability significantly reduces the time and effort required for measurement while maintaining precision.
Solution Approach 2:
The probe performs position detection automatically during the measurement process itself, rather than requiring separate manual positioning steps. This preliminary integration of detection functionality into the measurement action eliminates time-consuming manual measurement operations.
3Measurement precision
If multiple channels are used for biological light measurement, then measurement precision is improved, but device complexity and measurement burden increase
Solution Approach 1:
The patent combines multiple measurement channels into a single integrated probe structure. The probe includes multiple light irradiation position detection means and light detection position detection means that work together as one unit, reducing the complexity of managing multiple separate channels while maintaining comprehensive measurement capability.
Solution Approach 2:
The probe is designed as a multi-functional unit that simultaneously performs light irradiation, light detection, and position detection for multiple channels. This universal design reduces device complexity by consolidating multiple functions into a single probe while maintaining the precision needed for comprehensive biological measurements.
4Measurement precision
If accurate three-dimensional position information is obtained, then measurement precision is improved, but loss of time and effort increase
Solution Approach 1:
The probe automatically detects and records its own three-dimensional position information through integrated detection means, eliminating the need for manual measurement operations. This self-positioning capability obtains accurate three-dimensional position data without the time and effort required for manual measurement.
Solution Approach 2:
The patent replaces manual mechanical measurement operations with automated detection means integrated into the probe. The detection means electronically captures position information, substituting manual measurement processes and reducing the time and effort required while maintaining or improving measurement precision.
