Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If traditional methods are used to identify binding sites, then the process is simpler, but the accuracy and precision of binding site identification is insufficient

Engineering Contradiction:
Improvebinding site identification accuracyVSAvoidmethod complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent segments the binding site identification process into multiple independent computational modules: sequence analysis module, structural analysis module, binding affinity prediction module, and integration module. Each module processes specific features (amino acid sequences, 3D structures, binding energies) separately and outputs results that are integrated to identify binding sites, thereby improving accuracy while maintaining manageable complexity

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent merges multiple computational methods and data sources (sequence homology analysis, structural modeling, binding affinity calculations, and statistical analysis) into a unified identification system. This integration of diverse analytical approaches enables more accurate binding site identification by combining complementary strengths of different methods

Inventive Principle:
Principle #5Merging (Combining)

2Measurement precision

If comprehensive computational analysis is performed, then the identification precision improves, but the computational time and resources increase

Engineering Contradiction:
Improvebinding site identification accuracyVSAvoidcomputational time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent performs preliminary filtering and preprocessing of protein sequences and structures before main analysis. It pre-identifies conserved regions, predicts secondary structures, and filters potential binding sites based on structural features before applying computationally intensive binding affinity calculations, thereby reducing overall computational time while maintaining accuracy

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent implements a tiered analysis approach where it first performs rapid screening using simplified models to identify candidate binding sites, then applies more comprehensive computational methods only to these candidates. This partial application of intensive analysis to selected regions achieves high precision while minimizing total computational time and resources

Inventive Principle:
Principle #16Partial or excessive action
