1Loss of information

If compartmentalization is performed using traditional methods, then spatial information is preserved, but additional processing steps such as nucleotide amplification are required

Engineering Contradiction:

Improvespatial informationVSAvoidprocessing steps

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

The method segments the biological sample into discrete compartments within the polymer matrix, allowing individual cells or molecules to be isolated and analyzed separately while maintaining their spatial positions. This segmentation enables direct analysis without requiring additional processing steps to preserve spatial information.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The polymer matrix acts as an intermediary medium that simultaneously provides compartmentalization and maintains spatial information. By embedding the biological sample directly into the polymer matrix, the system eliminates the need for additional processing steps while preserving the spatial relationships of the sample components.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If compartmentalization is performed without additional processing steps, then assay efficiency is improved, but the ability to retain spatial information may be compromised

Engineering Contradiction:

Improveassay efficiencyVSAvoidspatial information

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

The polymer matrix is prepared in advance with the biological sample embedded within it, creating pre-formed compartments that contain the sample in its native spatial configuration. This preliminary action eliminates the need for subsequent processing steps to maintain spatial information, thereby improving assay efficiency while preserving spatial relationships.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The method changes the physical state and properties of the biological sample by embedding it in the polymer matrix, transitioning from a free-floating state to a fixed compartmentalized state. This parameter change allows direct analysis without additional processing steps while maintaining spatial information through the structural integrity of the polymer matrix.

Inventive Principle:

Principle #35Parameter changes

3Adaptability or versatility

If polymer matrix is generated around individual analytes, then compartmentalization is achieved, but device complexity increases

Engineering Contradiction:

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The system uses the biological sample itself to define the compartment boundaries by generating polymer matrix around individual analytes. This self-service approach allows the sample to dictate the compartmentalization structure, eliminating the need for complex pre-designed chamber structures and reducing overall device complexity while maintaining high adaptability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The compartmentalization structure is dynamic and adaptable, forming around individual analytes as needed rather than being fixed in advance. This dynamic approach allows the device to accommodate various types and numbers of analytes without requiring complex reconfiguration, achieving high versatility with simpler device architecture.

Inventive Principle:
