Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If ELISA or SPR technologies are used for bio-detection, then detection can be performed, but detection time increases due to required signal amplification
Solution Approach 1:
The patent replaces chemical-based detection systems (ELISA, SPR) with a terahertz wave-based detection system. The metamaterial layer interacts with terahertz waves to directly detect molecular vibrations and rotational transitions, eliminating the need for chemical markers and signal amplification steps, thus reducing detection time while maintaining detection capability
Solution Approach 2:
The patent utilizes the unique interaction parameters between terahertz waves and molecular structures. By detecting absorption spectra at specific terahertz frequencies that correspond to molecular vibrational modes, the system achieves direct detection without requiring signal amplification, thereby resolving the time-consuming nature of conventional methods
2Measurement precision
If ELISA or SPR technologies are used for bio-detection, then detection can be performed, but cost increases due to consumption of chemicals
Solution Approach 1:
The patent substitutes chemical-consuming detection methods with a physical field-based method using terahertz waves. The metamaterial layer enables direct interaction with target molecules through terahertz radiation, eliminating the need for consumable chemicals such as dyeing agents and ligands, thus reducing operational costs while maintaining detection accuracy
Solution Approach 2:
The terahertz wave detection system utilizes the intrinsic physical properties of molecules (vibrational and rotational transitions) for detection. The molecules themselves serve as the detection target without requiring external chemical markers or ligands, making the system self-sufficient and eliminating chemical consumption
3Measurement precision
If terahertz wave detection uses metamaterials to amplify signals, then detection sensitivity improves, but device complexity increases
Solution Approach 1:
The detection system is segmented into distinct functional layers: substrate layer, metamaterial layer, and protective layer. Each layer performs a specific function, with the metamaterial layer specifically designed for signal amplification through its resonant structures. This segmentation allows for optimized performance while maintaining manufacturing feasibility
Solution Approach 2:
The patent employs a composite structure combining metamaterials with standard substrate and protective materials. The metamaterial layer, composed of periodically arranged resonant elements, provides signal amplification functionality when integrated with conventional materials, achieving enhanced detection sensitivity without excessive overall complexity
