Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If multiple illumination sources with different frequencies are used to illuminate the anatomical target, then the ability to determine target composition is improved, but the device complexity increases
Solution Approach 1:
The illumination system is segmented into multiple independent illumination sources, each emitting light at different frequencies (e.g., red, green, blue LEDs). Each source can be independently controlled and timed, allowing the system to acquire spectral information across different wavelength ranges simultaneously without requiring a single complex broadband source with filters.
Solution Approach 2:
The multiple illumination sources are activated in a periodic, time-sequenced manner. The controller activates different illumination sources at different time intervals, creating a periodic illumination pattern that allows the sensor to capture images at different spectral bands sequentially. This periodic activation enables composition analysis through spectral comparison while managing system complexity through temporal separation.
2Measurement precision
If a series of different colored light sources are used for spectral analysis, then measurement precision is improved, but the time required for spectral profile acquisition increases
Solution Approach 1:
The illumination sources are activated in a periodic sequence where each source is turned on for a specific duration followed by a brief interval before the next source activates. This time-sequenced periodic activation allows the sensor to capture spectral information from multiple wavelengths in rapid succession, building a complete spectral profile through repeated cycles of illumination and detection.
Solution Approach 2:
The spectral profile acquisition process maintains continuity through rapid sequential activation of multiple illumination sources. By continuously cycling through different illumination sources in quick succession, the system maintains continuous illumination of the anatomical target while capturing spectral data across different bands, minimizing total acquisition time while preserving measurement precision.
3Productivity
If multiple illumination sources are activated simultaneously, then productivity is improved, but noise in the spectral signal increases
Solution Approach 1:
The illumination sources are activated periodically in a time-sequenced manner rather than simultaneously. Each illumination source is activated for a specific time window, then turned off before the next source activates. This periodic activation pattern allows the sensor to capture spectral information from each source in isolation, preventing signal overlap and noise while maintaining high acquisition speed through rapid sequential cycling.
