Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If expensive sensors are used to receive light beams for cell analysis, then detection accuracy is improved, but device cost increases
Solution Approach 1:
The patent uses a light-sensitive plate to capture optical images of cells, creating a visual copy of cell morphology and characteristics. This optical copying approach replaces expensive sensors while maintaining detection accuracy through image-based analysis of cell forward scattering light, side scattering light, and fluorescent light signals.
Solution Approach 2:
The invention employs disposable or low-cost light-sensitive plates instead of expensive, maintenance-intensive sensors. These plates can be replaced easily and at low cost, eliminating the high maintenance costs associated with conventional sensors while providing sufficient detection capability for cell analysis.
2Adaptability or versatility
If a culture dish with resistance detection is used for cell cultivation and analysis, then cell cultivation capability is added, but device cost increases
Solution Approach 1:
The patent integrates multiple functions into a single device: the culture dish serves both as a cultivation vessel and as an optical chamber for light beam transmission. The same culture dish that grows cells also serves as the medium through which light passes to reach the light-sensitive plate, eliminating the need for separate expensive resistance detection systems while maintaining both cultivation and analysis capabilities.
3Adaptability or versatility
If resistance-based detection is used for cell analysis, then cell cultivation and analysis are combined, but detection accuracy decreases
Solution Approach 1:
The patent replaces the electrical resistance detection mechanism with an optical detection system. Instead of measuring electrical resistance changes in the culture dish, the system uses light beams (laser or LED) that pass through the culture dish and cells to the light-sensitive plate, creating optical images that provide accurate morphological and biological characteristic data without compromising detection precision.

AI summary
A cell/particle analyzing device includes a light-emitting unit, a light-diverting unit, a first receiving unit and a second receiving unit. The light-emitting unit generates a first light beam. The light-diverting unit is connected to the light-emitting unit and has an input end, a bidirectional transceiving end and an output end. The input end receives the first light beam generated by the light-emitting unit. The bidirectional transceiving end transmits the first light beam generated by the light-emitting unit and receives a second light beam. The output end outputs the second light beam. The first receiving unit is connected to the output end of the light-diverting unit and receives the second light beam. The second receiving unit is aligned with the bidirectional transceiving end.
