Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional single-bandpass tunable filters are used, then the device complexity is low, but the measurement time increases and productivity decreases due to requiring multiple discrete bandpass measurements
Solution Approach 1:
The filter is divided into multiple independent tunable bandpass filters arranged in parallel, each capable of transmitting a specific wavelength bandpass. This segmentation allows multiple bands to be transmitted simultaneously rather than sequentially, dramatically increasing measurement speed while maintaining manageable complexity through modular design
Solution Approach 2:
The conformal filter design provides multi-functionality by enabling simultaneous transmission of multiple wavelength bandpasses through a single filter component. This universal filter can detect multiple analytes with different spectral features in a single measurement, eliminating the need for multiple discrete measurements and improving productivity
2Adaptability or versatility
If traditional single-bandpass filters are used, then the ease of operation is high, but the adaptability to detect a wide variety of analytes is limited
Solution Approach 1:
The filter incorporates dynamically tunable bandpass filters that can adjust their transmission characteristics in real-time. This dynamic capability allows the single filter to adapt to detect a wide variety of analytes with different spectral features, providing versatility while maintaining ease of operation through electronic control rather than mechanical reconfiguration
Solution Approach 2:
The filter enables parameter changes by allowing independent adjustment of central wavelength, bandwidth, and transmission depth for each parallel bandpass filter. This parametric flexibility provides adaptability to detect diverse analytes while maintaining ease of operation through software-controlled parameter adjustment rather than physical filter changes
3Loss of time
If multiple discrete bandpass measurements are performed sequentially, then the device complexity remains low, but the loss of time increases due to sequential measurement requirements
Solution Approach 1:
The patent merges multiple discrete bandpass measurement capabilities into a single filter component with parallel transmission paths. This consolidation allows simultaneous acquisition of multiple spectral bands through one optical path, eliminating the time loss associated with sequential measurements while managing complexity through integrated design
Solution Approach 2:
The conformal filter enables continuous useful action by allowing all wavelength bandpasses to be transmitted and measured simultaneously in a single continuous measurement process. This eliminates the interruptions and time losses inherent in sequential measurements, achieving continuous data acquisition across multiple spectral regions
