Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If polarization light beams of different directions are sequentially emitted to biological tissue, then measurement precision of tissue polarization properties is improved, but observation speed and real-time capability deteriorate
Solution Approach 1:
The emission unit sequentially emits polarization light beams with different polarization directions in periodic cycles. Each cycle includes multiple light beams with distinct polarization states that are systematically varied over time, enabling comprehensive polarization measurement while maintaining controlled observation speed through rhythmic emission patterns
Solution Approach 2:
The system dynamically adjusts the emission timing and polarization state of light beams based on real-time measurement requirements. The emission unit can modify the sequence and duration of polarization light beam emission to optimize between measurement precision and observation speed according to different tissue types and diagnostic needs
2Productivity
If multiple polarization light beams are emitted sequentially with non-overlapping emission periods, then productivity of data acquisition is improved, but device complexity increases
Solution Approach 1:
The emission unit divides the polarization light beam emission into distinct sequential segments, where each segment corresponds to a specific polarization direction. This segmentation allows independent control and optimization of each emission phase, improving data acquisition efficiency while managing system complexity through modular emission control
Solution Approach 2:
The system changes the polarization state parameter of emitted light beams in a systematic sequence. By varying only the polarization direction parameter while keeping other emission parameters consistent, the system achieves high productivity through parameter modulation without requiring complex structural changes to the emission apparatus
