1Productivity

If multiple separate devices and instrumentation are used for different analysis steps, then each device can be optimized for its specific function, but the physical complexity of the laboratory increases and throughput decreases

Engineering Contradiction:
ImprovethroughputVSAvoidphysical complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The patent merges multiple separate devices (sample preparation, reaction, separation, detection) into a single integrated microfluidic chip. This consolidation reduces the physical footprint and complexity of the laboratory setup while enabling high-throughput processing by allowing multiple analysis steps to occur simultaneously in parallel channels on the same chip.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The microfluidic chip is designed as a universal platform that can perform multiple different analysis steps across various biological applications. The same chip architecture supports sample preparation, reaction, separation, and detection functions, allowing the system to be adapted to different throughput requirements and assay types without requiring separate specialized equipment for each function.

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

2Device complexity

If analysis steps are integrated into a single footprint, then physical complexity is reduced, but the system must handle multiple functions simultaneously which increases operational complexity

Engineering Contradiction:
Improvephysical complexityVSAvoidoperational complexity
Core Design Contradiction:
Device complexityVSEase of operation

Solution Approach 1:

The integrated chip is segmented into distinct functional zones (sample preparation area, reaction chambers, separation channels, detection regions) that are spatially separated but functionally integrated. This segmentation allows each zone to be optimized for its specific operation while maintaining overall integration, reducing operational complexity by providing clear functional boundaries within the unified system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent employs automated fluid handling systems and integrated control mechanisms that act as intermediaries between the user and the complex multi-step processes. These intermediary systems automatically manage the coordination of multiple functions, handling liquid transfer, timing, and parameter control, thereby simplifying user operation despite the system's multifunctional complexity.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Measurement precision

If luminescent detection is integrated with liquid processing in individual conduits, then detection sensitivity is improved, but the manufacturing complexity of the conduit system increases

Engineering Contradiction:
Improvedetection sensitivityVSAvoidmanufacturing complexity
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The detection system is nested within the liquid processing conduit structure. The luminescent detection components (excitation sources, detectors) are integrated directly into or adjacent to the microfluidic channels, allowing detection to occur in-situ within the conduit system. This nesting approach improves detection sensitivity by minimizing sample handling and transfer, while the modular microfluidic design keeps manufacturing complexity manageable through standardized fabrication processes.

Inventive Principle:
Principle #7Nested doll (Nesting)
