Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If traditional biosensor systems are used for analyte detection, then detection capability is achieved, but cost and device complexity increase significantly
Solution Approach 1:
The patent uses optical copies of the analyte sample by reflecting light off the sample surface through the disk structure. The optical path creates a copy of the sample's optical properties that can be detected without direct contact, simplifying the detection mechanism while maintaining measurement capability.
Solution Approach 2:
The patent introduces an optical intermediary system using light reflection and transmission through the disk structure. This intermediary allows the analyte to be detected indirectly through its optical properties rather than requiring direct interaction with complex sensor components.
2Measurement precision
If laboratory analysis is performed for analyte detection, then accurate measurement is achieved, but time lag and sample degradation occur
Solution Approach 1:
The patent enables preliminary detection by allowing the analyte sample to be analyzed immediately upon collection using the optical detection system. The sample can be detected in real-time without requiring transport to a laboratory, eliminating the time lag between sampling and analysis.
Solution Approach 2:
The detection system is designed to be self-contained and portable, allowing the sample to be analyzed independently without requiring external laboratory facilities. The system performs detection functions that would traditionally require centralized laboratory equipment.
3Measurement precision
If sophisticated laboratory equipment is used for analyte detection, then detection sensitivity is improved, but accessibility and ease of operation deteriorate
Solution Approach 1:
The patent simplifies operation by using optical copies and reflections that can be detected by standard optical sensors. The complex analyte detection is transformed into a simpler optical measurement problem that can be performed with more accessible equipment.
Solution Approach 2:
The patent changes the detection parameter from direct chemical or biological measurement to optical property measurement. This parameter transformation allows the use of standard optical detection methods instead of sophisticated specialized equipment, improving accessibility while maintaining sensitivity.

AI summary
A system, method, device, and process for making and using an electromagnetic-sensitive biosensor on a biosensor disk to identify and classify an analyte in a sample. The biosensor of the biosensor disk is exposed to a sample containing analytes and a desired analyte adheres to the biosensor. The biosensor disk is rotated during operation and an electromagnetic emitter directs an electromagnetic radiation beam at the biosensor disk. The returned electromagnetic radiation from the biosensor disk is received by a sensor that converts the returned electromagnetic radiation into a signal to indicate the presence of the desired analyte in the sample.
