Solution Overview

Problem

The detection and quantification of double-stranded RNA (dsRNA) are challenging due to the limited availability of dsRNA-specific antibodies and the difficulty in developing sequence-independent antibodies.

Innovation Solution

Development of antibodies and antigen-binding fragments that specifically bind to dsRNA in a sequence-independent manner, which can be used in detection methods such as Enzyme-Linked Immunosorbent Assays (ELISAs).

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional detection methods are used, then the detection process is simple, but the sensitivity and precision of dsRNA detection are insufficient

Engineering Contradiction:

Improvedetection sensitivityVSAvoiddetection method complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces dsRNA-specific antibodies as intermediary molecules that specifically bind to dsRNA targets. These antibodies serve as mediators between the dsRNA analyte and the detection system (ELISA), enabling sensitive and specific detection through the antibody-antigen interaction mechanism.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Measurement precision

If dsRNA-specific antibodies are developed, then detection sensitivity improves, but the difficulty of developing sequence-independent antibodies increases

Engineering Contradiction:

Improvedetection sensitivityVSAvoidantibody development difficulty

Core Design Contradiction:

Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent develops dsRNA-specific antibodies that recognize universal structural features of double-stranded RNA rather than sequence-specific epitopes. This universal recognition capability allows a single antibody to detect various dsRNA sequences, achieving multi-functionality and reducing the need to develop different antibodies for different RNA targets.

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Adaptability or versatility

If sequence-independent antibodies are used, then broad-spectrum detection is achieved, but the availability of such antibodies is limited

Engineering Contradiction:

Improvedetection breadthVSAvoidantibody availability

Core Design Contradiction:

Adaptability or versatilityVSQuantity of substance

Solution Approach 1:

The patent employs parameter changes in the antibody development process, specifically targeting the structural conformation parameters of dsRNA rather than sequence parameters. By changing the recognition parameter from sequence-specific to structure-specific, the antibodies achieve broad-spectrum detection capability across different RNA sequences while maintaining high availability through standardized production methods.

Inventive Principle:

Principle #35Parameter changes
