Innovation Solution

An all-in-one self-test kit integrating a reagent container, diagnosis kit, and swab disposal components within a compact design, featuring a straight tube-shaped storage portion with protrusions, a sealing cover, and a transparent diagnosis strip for visual result observation, allowing for simple and rapid specimen collection and reaction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If molecular diagnosis is performed in a laboratory with large-scale test equipment, then diagnostic accuracy is improved, but the time required for diagnosis increases and the process becomes complex

Engineering Contradiction:
Improvediagnostic accuracyVSAvoiddiagnosis time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The invention extracts the essential molecular diagnosis function from complex laboratory equipment and implements it in a simplified self-test kit format. The test kit contains pre-packaged reagents and a test strip that can perform molecular diagnosis outside the laboratory, enabling rapid at-home testing while maintaining diagnostic accuracy through preserved nucleic acid detection capability.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention enables self-service molecular diagnosis by providing a self-test kit that requires no specialized laboratory equipment or personnel. Users can independently collect specimens, perform the test, and obtain results at home, eliminating the time loss associated with laboratory scheduling and processing while maintaining diagnostic accuracy through standardized reagents and procedures.

Inventive Principle:
Principle #25Self-service

2Measurement precision

If conventional self-test kits are designed with multiple components for molecular diagnosis, then diagnostic capability is improved, but device complexity increases and ease of operation decreases

Engineering Contradiction:
Improvediagnostic capabilityVSAvoidkit structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The invention merges multiple test components (reagent container, test strip, control mechanisms) into a single integrated self-test kit unit. The reagent container and test strip are pre-assembled with alignment features, and the entire kit is housed in a unified casing, reducing the number of separate components users must handle while preserving full molecular diagnosis capability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention applies nesting by placing the test strip inside the reagent container, and the entire assembly inside a protective casing. This nested structure consolidates multiple components into a compact single unit that is easy to store, transport, and operate, significantly reducing perceived device complexity while maintaining diagnostic capability.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Ease of operation

If self-test kits are designed for home use, then ease of operation is improved, but the ability to perform accurate molecular diagnosis deteriorates

Engineering Contradiction:
Improveuser-friendlinessVSAvoidmolecular diagnosis accuracy
Core Design Contradiction:
Ease of operationVSMeasurement precision

Solution Approach 1:

The invention applies preliminary action by pre-packaging reagents in stable formulations that do not require complex preparation, pre-assembling the test strip with reagents in correct orientations, and pre-establishing specimen-to-reagent flow paths. These preliminary preparations enable users to perform accurate molecular diagnosis at home without needing to understand complex procedures, maintaining diagnostic accuracy while maximizing ease of operation.
