Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional laboratory instruments with multiple assembled units and construction components are used, then the instrument can perform various sample processing steps, but the working surface possesses gaps and splits which complicate thorough cleaning and can lead to cross-contamination

Engineering Contradiction:
Improvecleaning efficiencyVSAvoidstructure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges multiple separate construction components and assembled units into a single integrated base plate structure. This base plate contains all necessary mounting locations, compartments, and support elements as one unified component, eliminating the gaps and splits that occur between separately assembled parts. The merging of structures directly resolves the cleaning efficiency problem by creating a continuous, gap-free surface.

Inventive Principle:
Principle #5Merging (Combining)

2Adaptability or versatility

If multiple assembled units and construction components are used to build the working surface, then various functions can be accommodated, but small gaps and splits are created which complicate thorough cleaning

Engineering Contradiction:
Improvefunctional versatilityVSAvoidcleaning thoroughness
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The single base plate is designed with multi-functionality, incorporating various compartments, mounting locations, and support structures within one unified component. This universal design provides all necessary functions (consumable storage, device mounting, waste containment) without requiring separate assembled units, thereby maintaining functional versatility while eliminating gaps that hinder cleaning.

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

3Adaptability or versatility

If the working surface has multiple gaps and splits from assembled components, then various units can be accommodated, but cross-contamination risks increase in sensitive nucleic acid analytics

Engineering Contradiction:
Improveunit accommodationVSAvoidcross-contamination risk
Core Design Contradiction:
Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

By merging all working surface elements into a single integrated base plate, the invention eliminates the gaps and splits between assembled components. This continuous surface prevents the cross-contamination pathways that could exist between separate units, directly addressing the harmful factor of cross-contamination in sensitive nucleic acid analytics while maintaining the ability to accommodate various functional units.

Inventive Principle:
Principle #5Merging (Combining)

4Adaptability or versatility

If conventional assembled structures are used, then the instrument can be built with multiple functional units, but positioning accuracy of pipetting devices may drift over time requiring frequent calibration

Engineering Contradiction:
Improvefunctional capabilityVSAvoidpositioning accuracy
Core Design Contradiction:
Adaptability or versatilityVSMeasurement precision

Solution Approach 1:

The single base plate incorporates pre-defined, precisely engineered mounting locations and reference structures during manufacturing. These preliminary positioning features ensure that pipetting devices are accurately positioned from the outset and maintain their alignment over time, reducing the need for frequent calibration. The integrated structure prevents the positional drift that can occur with separately assembled components.

Inventive Principle:
