Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If automated biological analysis systems are implemented, then efficiency and productivity are improved, but device complexity and installation difficulty increase

Engineering Contradiction:
Improveanalysis efficiencyVSAvoidsystem complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The biological analysis system is divided into separate functional modules: a sample processing module with temperature cycling capability, and a separate detection module with optical detection system. These modules can be used independently or combined, reducing overall system complexity while maintaining high productivity through automated processing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system design allows a single module to serve multiple functions - the sample block assembly can be used with different detection modules, and the tray mechanism supports various sample holder configurations. This multi-functionality reduces the need for multiple specialized devices, simplifying installation while preserving automated efficiency.

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

2Adaptability or versatility

If modular reversible connection design is used, then ease of installation and adaptability are improved, but device complexity increases

Engineering Contradiction:
Improvedevice configuration flexibilityVSAvoidconnection mechanism complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The connection between modules uses a dynamic reversible mechanism where the detection module can be easily attached to and detached from the sample processing module. This dynamic connection system allows flexible reconfiguration for different experimental needs without requiring complex permanent assemblies, balancing adaptability with manageable complexity.

Inventive Principle:
Principle #15Dynamics

3Area of stationary object

If compact design is implemented, then lab space requirements are reduced, but ease of operation and user access deteriorate

Engineering Contradiction:
Improvelab space requirementVSAvoiduser access to samples
Core Design Contradiction:
Area of stationary objectVSEase of operation

Solution Approach 1:

The system uses a vertical stacking arrangement where the detection module is positioned above the sample block, and the tray mechanism provides vertical access rather than horizontal. This three-dimensional compact design reduces the horizontal lab space footprint while maintaining easy user access through the vertically sliding tray mechanism.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

4Measurement precision

If integrated optical and thermal systems are combined, then measurement precision is improved, but device complexity and manufacturing difficulty increase

Engineering Contradiction:
Improvefluorescence detection accuracyVSAvoidsystem integration complexity
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The optical detection system and thermal cycling system are manufactured as separate modules with well-defined interfaces. The sample block assembly is manufactured independently with precise thermal characteristics, while the detection module is manufactured separately with optimized optical pathways. This segmentation enables specialized manufacturing for each module, improving overall measurement precision while simplifying the manufacturing process through modular production.

Inventive Principle:
Principle #1Segmentation
