Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional measurement technology is used to detect cell vibrations, then the measurement system is simple, but the vibrational signals are overwhelmed by noise and cannot be captured accurately
Solution Approach 1:
The measurement system is segmented into two independent paths: a principal path that measures the actual cell vibrations and a reference path that measures only the environmental noise. By separating the measurement into these two independent channels, the system can later subtract the reference noise from the principal measurement to isolate the true vibrational signals, thereby achieving high measurement precision without requiring a single overly complex detector system.
Solution Approach 2:
The reference medium acts as an intermediary that captures and transmits the environmental noise characteristics to the reference detector. This intermediary element allows the system to indirectly measure the noise components that would otherwise contaminate the direct cell vibration measurement, enabling the subsequent noise subtraction process to effectively isolate the true vibrational signals.
2Ease of operation
If time-lapse video photography is used to observe cell movements, then the system is easy to operate, but the real-time measurement capability is severely limited
Solution Approach 1:
The system replaces the mechanical video photography approach with an optical measurement system that uses photon beams and photodetectors to directly measure cell vibrations. This substitution of the detection mechanism enables real-time measurement of vibrational spectra while maintaining operational simplicity through automated data processing and noise reduction algorithms.
3Reliability
If current technology is used to measure vibrational signals, then the measurement process is straightforward, but the noise from the measurement system overwhelms the cell-generated signals
Solution Approach 1:
The reference measurement path extracts and isolates the environmental noise components from the overall measurement system. By capturing the noise characteristics in the reference path and subsequently subtracting them from the principal measurement, the system removes the harmful noise factors that would otherwise overwhelm the微弱 cell-generated vibrational signals, thereby achieving reliable signal capture.
Solution Approach 2:
The system uses the reference measurement as feedback to continuously characterize and compensate for environmental noise. The reference detector provides real-time noise information that is used to adjust and correct the principal measurement, creating a feedback loop that actively suppresses measurement system noise and maintains high signal capture reliability under varying environmental conditions.
