Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for detecting biological contaminants in water, such as pathogens and biotoxins, are costly, time-consuming, and often yield false positives or negatives, and lack simplicity and effectiveness for field deployment.
Innovation Solution
The use of glycoprotein micelles and vesicles, which interact with biological contaminants through carbohydrate-binding adhesins (lectins), allowing for the detection and concentration of pathogens and biotoxins by agglutination, providing a cost-effective and rapid method for identifying contaminants in aqueous environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If immunoassay devices using antibodies are used to detect biological contaminants, then detection capability is improved, but cost and time consumption increase significantly
Solution Approach 1:
The patent replaces expensive, complex antibodies with inexpensive lectins that can be easily extracted from plant sources. These lectins serve as disposable detection reagents that provide sufficient detection capability without requiring the complex production and purification processes needed for antibodies, thereby reducing both cost and time consumption while maintaining detection functionality
Solution Approach 2:
The patent uses lectins as a simplified copy or alternative to antibodies for detection purposes. Instead of using the complex antibody-antigen recognition system, the patent employs lectin-carbohydrate binding as a functional equivalent that achieves detection capability with significantly reduced complexity, time, and resource requirements
2Measurement precision
If immunoassay devices using antibodies are used to detect biological contaminants, then detection capability is improved, but cost increases
Solution Approach 1:
The patent replaces expensive, complex antibodies with inexpensive lectins that can be easily extracted from plant sources. These lectins serve as disposable detection reagents that provide sufficient detection capability without requiring the complex production and purification processes needed for antibodies, thereby reducing both cost and time consumption while maintaining detection functionality
Solution Approach 2:
The patent enables lectins to perform detection functions independently without requiring the complex support infrastructure needed for antibody-based systems. Lectins can be directly extracted from plants and used for detection, eliminating the need for sophisticated manufacturing, purification, and storage facilities required for antibody production, thereby significantly reducing manufacturing costs
3Reliability
If complex detection systems with multiple components are used, then detection reliability is improved, but device complexity increases
Solution Approach 1:
The patent extracts only the essential detection function from complex immunoassay systems by using lectins that directly bind to carbohydrates on pathogen surfaces. This extraction eliminates unnecessary components such as complex buffer systems, multiple washing steps, and sophisticated signal amplification mechanisms, thereby reducing device complexity while maintaining detection reliability through the straightforward lectin-carbohydrate binding mechanism
Solution Approach 2:
Instead of using complex antibodies that require elaborate production and application protocols, the patent inverts the approach by using simple lectins that can be directly applied. This inversion simplifies the detection system by replacing the complex antibody-based paradigm with a simpler lectin-based system that achieves reliable detection with fewer components and steps
4Ease of operation
If field-deployable detection technologies are implemented, then ease of operation is improved, but detection precision may worsen
Solution Approach 1:
The patent uses inexpensive lectins that can be easily prepared and deployed in field settings without requiring sophisticated laboratory infrastructure. These lectins provide sufficient detection precision for field applications while enabling easy operation through simple extraction and direct application methods that do not require complex equipment or highly trained personnel
