Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If reagents are used in chemical analysis, then chemical analysis can be performed, but impurities in reagents will affect the validity of the analysis
Solution Approach 1:
The reagent cartridge is divided into multiple separate chambers, each containing a specific reagent. This segmentation prevents cross-contamination between different reagents and allows for dedicated storage and handling of each chemical component, thereby maintaining reagent purity and analysis validity.
Solution Approach 2:
An authentication device acts as an intermediary between the reagent cartridge and the analysis system. This device verifies the authenticity and purity of reagents before they are used, preventing impure or counterfeit reagents from compromising the chemical analysis validity.
2Measurement precision
If incorrect reagents are used, then chemical analysis can be conducted, but measurement precision will be compromised
Solution Approach 1:
The authentication device provides feedback to the analysis system about the reagent's authenticity and suitability. This feedback mechanism ensures that only verified, correct reagents are used in the analysis, maintaining both measurement precision and analytical accuracy.
Solution Approach 2:
The system changes the state of reagent verification from passive to active by implementing authentication checks. This parameter change in the verification process ensures that reagents meet specific purity and correctness criteria before use, thereby保障ing measurement precision.
3Volume of stationary object
If multiple reagents are stored together, then storage space is reduced, but risk of contamination and incorrect reagent use increases
Solution Approach 1:
Multiple reagents are stored in separate, physically isolated chambers within the cartridge. This segmentation maintains compact storage volume while preventing contamination between different reagents, as each chamber is designed to contain its specific reagent exclusively.
Solution Approach 2:
The reagent chambers are nested within a compact cartridge structure, allowing multiple reagents to be stored in a space-efficient manner. The nested design minimizes the overall volume while maintaining separate compartments for each reagent, preventing cross-contamination.
4Reliability
If reagent authentication is implemented, then reagent purity is ensured, but device complexity increases
Solution Approach 1:
The authentication device is designed to automatically verify reagent authenticity without requiring manual intervention. The self-service authentication mechanism simplifies the complexity by automating the verification process, maintaining reagent purity while minimizing operational complexity.
Solution Approach 2:
The authentication device is merged with the reagent cartridge as an integrated component. This combination reduces overall system complexity by consolidating verification functions within the cartridge itself, rather than requiring separate external authentication systems.
