VSEngineering Contradiction Analysis

1Productivity

If current methods for RNA detection and protein analysis are used, then detection accuracy is maintained, but the process requires cumbersome purification protocols and enzymatic reactions, increasing device complexity and processing time

Engineering Contradiction:
Improvethroughput detection capabilityVSAvoidpurification protocol complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The invention extracts and eliminates the cumbersome purification and enzymatic reaction steps from the detection process. By using affinity reagents that directly bind target analytes and ID reagents with capture reagents and barcodes, the method removes the need for complex purification protocols and enzymatic amplification steps, thereby simplifying the overall detection system while maintaining high throughput capability

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention employs multifunctional ID reagents that combine capture reagents, barcodes, and optional amplification sequences into a single universal platform. This multi-functional design allows the same basic system to detect various target analytes (proteins, antibodies, nucleic acids, small molecules) without requiring separate complex purification and detection protocols for each analyte type, thus improving throughput while reducing overall system complexity

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

2Productivity

If current methods with labeled antibodies and enzymatic reactions are used, then target analyte detection is achieved, but reagent cost and processing time increase

Engineering Contradiction:

Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The invention performs preliminary action by pre-attaching barcodes and capture reagents to ID reagents before the detection process. This pre-preparation eliminates the need for time-consuming enzymatic reactions and label attachment steps during actual detection, allowing for rapid processing of large numbers of samples while reducing turnaround time

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The invention uses barcode sequences as information copies that can be read without requiring expensive labeled antibodies or complex enzymatic reactions. The barcode serves as a stable, inexpensive information carrier that replaces costly detection reagents, thereby reducing both reagent costs and processing time while maintaining detection capability

Inventive Principle:
Principle #26Copying
