Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If skin is illuminated with radiation in a narrow wavelength range, then the device complexity is reduced, but the quantity of information retrieved is limited
Solution Approach 1:
The illumination device is segmented into multiple independent emitters, each covering a specific wavelength range (UV, visible, infrared). This allows the system to cover broad spectral information while keeping each individual emitter simple and manageable.
Solution Approach 2:
The device performs multiple functions by integrating emitters across different wavelength ranges into a single system. One device simultaneously provides UV, visible, and infrared illumination, enabling comprehensive skin characterization without requiring multiple separate devices.
2Measurement precision
If skin is illuminated with radiation in a narrow wavelength range, then the ease of operation is improved, but the measurement precision is reduced
Solution Approach 1:
The measurement system is segmented into separate emitters and detectors for different wavelength ranges. This segmentation allows precise measurements at each wavelength while the automated control system maintains ease of operation by managing the complexity of coordinating multiple components.
Solution Approach 2:
The system incorporates feedback mechanisms where the control unit monitors and coordinates the operation of emitters and detectors. This feedback control ensures precise spectral measurements while automatically adjusting parameters to maintain ease of operation for the user.
3Loss of information
If multiple wavelength ranges are used to illuminate skin, then the quantity of information is increased, but the device complexity increases
Solution Approach 1:
Multiple emitters covering different wavelength ranges (UV, visible, infrared) are merged into a single integrated illumination device. Similarly, detectors for different wavelengths are combined into one measurement system, enabling comprehensive information retrieval while managing device complexity through unified control.
Solution Approach 2:
The device is designed as a universal system that performs multiple measurement functions simultaneously. By integrating diverse emitters and detectors into one platform with automated control, the system maximizes information retrieval while the control unit manages the operational complexity.
4Measurement precision
If a broad spectrum of radiation is used to illuminate skin, then the measurement precision is improved, but the ease of operation deteriorates
Solution Approach 1:
The control unit implements feedback control to manage the complexity of coordinating multiple emitters and detectors across broad spectral ranges. This feedback mechanism automatically adjusts operation parameters, maintaining ease of use while enabling precise measurements across the entire spectrum.
Solution Approach 2:
The system is designed to self-regulate and automatically coordinate the operation of multiple emitters and detectors. The control unit manages the complexity of broad-spectrum illumination and detection, allowing users to operate the system easily without manually coordinating multiple components.
