Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If centralized laboratory-based molecular diagnostics testing is used, then measurement precision is improved, but device complexity and loss of time increase
Solution Approach 1:
The patent divides the molecular diagnostics testing system into discrete functional modules: sample processing module, nucleic acid amplification module, and detection module. Each module performs a specific function and can be independently optimized, allowing the system to maintain high precision while reducing overall complexity through modular design.
Solution Approach 2:
The patent extracts and integrates essential functions from centralized laboratories into a portable platform. By taking out the core capabilities of nucleic acid amplification and detection and embedding them in a self-contained device, the system eliminates the need for complex centralized infrastructure while maintaining diagnostic accuracy.
2Measurement precision
If centralized laboratory-based molecular diagnostics testing is used, then measurement precision is improved, but loss of time increases
Solution Approach 1:
The patent incorporates preliminary sample processing and reagent preparation directly into the device before testing. By performing sample lysis, nucleic acid extraction, and reagent mixing in advance within the integrated system, the device eliminates time-consuming steps that would otherwise require centralized laboratory processing, thereby reducing turn-around time while maintaining precision.
Solution Approach 2:
The patent enables continuous testing capability by integrating all necessary functions in a single platform that can process samples continuously without interruption. The automated workflow allows for continuous nucleic acid amplification and detection cycles, eliminating the batch processing delays inherent in centralized laboratories and reducing overall turn-around time.
3Ease of operation
If known point of care tests are used, then ease of operation is improved, but measurement precision deteriorates
Solution Approach 1:
The patent implements self-service capabilities by automatically performing sample processing, nucleic acid amplification, and detection without requiring skilled laboratory personnel. The integrated device performs all necessary functions autonomously through automated workflows, maintaining ease of operation for end-users while ensuring high measurement precision through controlled automated processes.
Solution Approach 2:
The patent replaces manual mechanical operations with automated electronic and optical systems. Instead of requiring skilled technicians to perform manual sample handling and analysis, the device uses automated fluid handling, thermal cycling, and digital detection systems, thereby maintaining operational simplicity while improving measurement precision through consistent automated execution.
4Measurement precision
If sophisticated optical detection systems are used in laboratory-based testing, then measurement precision is improved, but device complexity and object-generated harmful factors increase
Solution Approach 1:
The patent changes the detection parameters by using digital detection with a light source and detector that operates at safe power levels. Instead of relying on high-power laser systems, the device uses controlled light emission and electronic detection that maintains precision while eliminating safety hazards associated with high-energy optical systems.
Solution Approach 2:
The patent substitutes sophisticated optical detection systems with an electronic detection system that uses a light emitting device and light detecting device. This replacement maintains detection sensitivity while eliminating the safety hazards associated with complex optical systems, lasers, and high-power light sources through the use of safer electronic components.
5Measurement precision
If laboratory-based molecular diagnostics testing is used, then measurement precision is improved, but ease of manufacture deteriorates
Solution Approach 1:
The patent segments the testing system into modular components that can be manufactured separately and then assembled. This segmentation allows each module to be optimized for manufacturing efficiency while maintaining the overall precision of the diagnostic system, thereby improving ease of manufacture without sacrificing measurement precision.
Solution Approach 2:
The patent employs disposable test cartridges that contain all necessary reagents and components for a single use. This approach simplifies manufacturing by eliminating the need for complex, expensive, and difficult-to-manufacture reusable instruments, while maintaining high measurement precision through carefully designed disposable components that are easier and cheaper to produce.
