Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If separate mirrors are used to split fluorescence signals from visible light signals, then signal separation is achieved, but the structural space required increases and device complexity increases
Solution Approach 1:
The patent combines multiple optical functions (beam splitting, signal separation, and detection) into a single integrated optoelectronic converter with multiple partial regions. This eliminates the need for separate mirrors and multiple discrete components, thereby reducing structural space while maintaining signal separation capability.
Solution Approach 2:
The optoelectronic converter is designed with multi-functionality, serving both as a beam splitter and a signal detector. Different partial regions of the converter handle different wavelength ranges (fluorescence and visible light), allowing one component to perform multiple functions that previously required separate mirrors and detectors.
2Adaptability or versatility
If separate mirrors and multiple converters are used for processing different signals, then signal processing capability is improved, but device complexity increases and ease of manufacture decreases
Solution Approach 1:
Multiple signal processing functions are merged into a single optoelectronic converter. The converter includes different partial regions that can be assigned to different wavelength ranges, allowing it to process both fluorescence and visible light signals simultaneously without requiring multiple separate converters and associated mirror systems.
Solution Approach 2:
The optoelectronic converter is segmented into multiple partial regions, each capable of handling specific wavelength ranges. This segmentation allows the single converter to process different signal types independently, maintaining signal processing capability while simplifying the overall device structure.
3Measurement precision
If separate mirrors and converters are used, then signal detection is achieved, but the number of components increases making channel extension difficult
Solution Approach 1:
The optoelectronic converter is designed with universal applicability for detecting multiple wavelength ranges. By assigning different partial regions to different wavelength ranges, the system can easily extend its functionality to process additional signal channels without adding complex mirror arrangements or multiple converters, thereby improving ease of manufacture and channel extension.
