Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If conventional exosome detection methods are used, then detection can be performed, but the process is time-consuming due to additional antibody binding steps
Solution Approach 1:
The patent combines the capture antibody and detection antibody into a single integrated antibody structure that is directly immobilized on the sensor surface. This merging eliminates the need for separate capture and detection steps, allowing simultaneous binding of exosomes and signal generation in a single operational step, thereby reducing detection time and process complexity
Solution Approach 2:
The patent performs preliminary action by pre-immobilizing the integrated antibody structure on the sensor surface before sample introduction. This preliminary preparation ensures that the detection system is ready to immediately bind and detect exosomes upon contact, eliminating the need for subsequent antibody addition steps and reducing overall detection time
2Productivity
If conventional exosome detection methods are used, then detection can be performed, but additional steps are required reducing efficiency
Solution Approach 1:
The patent merges multiple detection functions into a single integrated antibody structure that performs both capture and detection simultaneously. This integration reduces the number of operational steps required, improving detection efficiency by eliminating sequential processing requirements and enabling faster throughput
Solution Approach 2:
The integrated antibody structure serves multiple functions simultaneously: it acts as both the capture agent for exosomes and the detection signal generator. This multi-functionality reduces the number of separate components and steps needed, thereby improving productivity and simplifying the overall detection process
3Measurement precision
If conventional detection methods are used, then detection can be performed, but specificity is insufficient leading to non-specific adsorption
Solution Approach 1:
The patent applies local quality by creating a specific microenvironment at the sensor surface through the integrated antibody structure. The antibody's unique molecular structure provides specific binding sites that selectively recognize exosome markers, while the local chemical environment is engineered to prevent non-specific binding. This localized specificity reduces non-specific adsorption while maintaining high detection precision
Solution Approach 2:
The integrated antibody structure acts as an intermediary that selectively mediates the interaction between the sensor surface and exosomes. It provides specific molecular recognition through its antibody binding sites, filtering out non-specific interactions while allowing targeted binding to exosome markers, thereby improving specificity and reducing harmful non-specific adsorption
