Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional experimental methods are used to identify antigens that bind to immune cell receptors, then the reliability of antigen identification is improved, but the time consumption and experimental cost increase significantly

Engineering Contradiction:
Improveantigen identification accuracyVSAvoidexperiment time
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent performs preliminary feature extraction from genetic information, sequence information, and three-dimensional structure features before actual antigen prediction. By pre-processing and encoding these features into comprehensive receptor representations, the system reduces the computational burden during the actual prediction phase, enabling faster antigen identification while maintaining accuracy through pre-computed structural and sequence characteristics.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent creates a computational model that replicates the biological binding interaction between immune cell receptors and antigens. Instead of performing physical experiments to test each antigen-receptor pair, the system uses a trained prediction model that copies the essential binding characteristics, allowing virtual screening of multiple candidate antigens against a single receptor without time-consuming wet lab experiments.

Inventive Principle:
Principle #26Copying

2Measurement precision

If comprehensive feature extraction from genetic, sequence, and structural information is performed, then the prediction accuracy of antigen binding is improved, but the computational complexity increases

Engineering Contradiction:
Improveprediction accuracyVSAvoidmodel complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the antigen prediction task into three distinct feature extraction modules: genetic information processing, sequence information analysis, and three-dimensional structure feature extraction. Each module independently processes its specific input type and produces specialized features, which are then integrated. This segmentation allows each component to be optimized separately and simplifies the overall model architecture by dividing the complex prediction task into manageable, specialized sub-tasks.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent merges the outputs from the three separate feature extraction modules (genetic features, sequence features, and structural features) into a comprehensive receptor feature representation. By integrating these diverse feature types through concatenation or fusion operations, the model creates a unified and rich input representation that captures multiple aspects of receptor characteristics, thereby improving prediction accuracy without requiring a fundamentally more complex model architecture.

Inventive Principle:
Principle #5Merging (Combining)

3Adaptability or versatility

If the antigen prediction model processes multiple candidate antigens for each receptor, then the completeness of antigen identification is improved, but the computational resources required increase

Engineering Contradiction:
Improveantigen screening coverageVSAvoidcomputational energy
Core Design Contradiction:
Adaptability or versatilityVSUse of energy by moving object

Solution Approach 1:

The patent replaces the mechanical process of physical antigen-screening experiments with a computational prediction system. Instead of using laboratory equipment and reagents to test each antigen-receptor interaction, the system uses a trained machine learning model that performs predictions through mathematical computations. This substitution dramatically reduces energy consumption while enabling the screening of multiple candidate antigens, as computational predictions require minimal energy compared to repeated wet lab experiments.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)
