Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If samples and reagents are exposed to external environment during testing, then testing flexibility is improved, but contamination risk increases and accuracy deteriorates

Engineering Contradiction:
Improvetesting flexibilityVSAvoidaccuracy
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent combines sample chambers, reagent chambers, and detection parts into an integrated cuvette system that moves as a single unit through the station. This merging allows the sample and reagent to be handled together in a controlled environment while maintaining testing flexibility, preventing contamination without sacrificing operational ease.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The patent introduces a closed cuvette system as an intermediary between the sample/reagent and the external environment. The cuvette acts as a mediator that protects samples and reagents from contamination while allowing them to be processed through the station's mechanisms for mixing, reaction, and detection.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Loss of time

If sequential testing is performed in a single integrated system, then analysis time and cost are reduced, but system complexity increases

Engineering Contradiction:
Improveanalysis timeVSAvoidsystem complexity
Core Design Contradiction:
Loss of timeVSDevice complexity

Solution Approach 1:

The patent designs a multi-functional station that can perform sample loading, reagent addition, mixing, reaction, and detection within a single integrated system. The cuvette serves multiple functions (sample containment, reagent delivery, reaction vessel, and detection window), reducing the need for separate devices and minimizing analysis time while managing complexity through functional integration.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent enables continuous processing where the cuvette moves sequentially through different functional zones (sample chamber, reagent chamber, detection part) without interruption. The automated movement and processing steps ensure continuous useful action, eliminating idle time between operations and reducing overall analysis time.

Inventive Principle:
Principle #20Continuity of useful action

3Productivity

If multiple diagnostic kits are tested simultaneously, then productivity increases, but device complexity and contamination control difficulty increase

Engineering Contradiction:
Improvetesting throughputVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent divides the testing capacity into multiple parallel cuvette positions within the station, allowing multiple diagnostic kits to be processed simultaneously at different locations. This segmentation enables parallel processing of multiple samples while maintaining individual control over each test, increasing productivity without excessive complexity.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs dynamic positioning mechanisms that can move individual cuvettes or groups of cuvettes to different functional zones as needed. This dynamic capability allows flexible configuration of multiple tests simultaneously while adapting to different testing scenarios, improving throughput without fixed complex infrastructure.

Inventive Principle:
Principle #15Dynamics

4Manufacturing precision

If precise control over sample and reagent handling is implemented, then manufacturing precision and accuracy are improved, but device complexity and operation difficulty increase

Engineering Contradiction:
Improveamount control precisionVSAvoidsystem complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The patent designs the cuvette and station system to automatically control sample and reagent handling through integrated mechanisms. The system self-regulates the precise amounts of sample and reagent that mix and react within the cuvette, eliminating the need for complex external control systems while maintaining high precision in amount control.

Inventive Principle:
Principle #25Self-service
