Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If real detection sensors are installed and operated in a protected region to monitor pollution spread, then measurement precision is improved, but device complexity and maintenance costs increase

Engineering Contradiction:
Improvepollution concentration measurement accuracyVSAvoidsensor installation and maintenance complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent creates a virtual copy of the physical sensor network through AI-based simulation. The system uses pollution diffusion prediction modeling to generate virtual sensor data that replicates what physical sensors would measure, eliminating the need for actual sensor installation while maintaining measurement capability. This is achieved by inputting weather data, geography information, and building data into the prediction model to simulate pollution concentration at various locations.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The patent replaces the mechanical sensor-based measurement system with an AI-based prediction system. Instead of using physical sensors to directly measure pollution concentrations, the system uses machine learning models that process weather, geography, and emission data to predict pollution levels. This substitution eliminates the need for physical sensor installation and maintenance while providing comparable or superior measurement precision.

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

2Device complexity

If pollution diffusion prediction modeling technology is used to predict CBRN pollutant spread, then device complexity is reduced, but measurement precision deteriorates in complex urban areas

Engineering Contradiction:
Improveprediction system simplicityVSAvoidpollution spread prediction accuracy
Core Design Contradiction:
Device complexityVSMeasurement precision

Solution Approach 1:

The patent divides the prediction task into multiple specialized components: a weather model for atmospheric conditions, a pollution diffusion prediction model for concentration calculations, and an AI-based correction model for refinement. Each component handles a specific aspect of the prediction, allowing the system to maintain simplicity while improving accuracy through modular specialization. The segmentation enables parallel processing of different data types and independent optimization of each model component.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent implements a feedback mechanism where the AI model corrects the output of the pollution diffusion prediction model based on patterns learned from historical data. The correction model receives initial predictions, compares them with actual sensor measurements when available, and adjusts the predictions accordingly. This feedback loop continuously improves prediction accuracy in complex urban environments without requiring complete redesign of the prediction system.

Inventive Principle:
Principle #23Feedback

3Area of stationary object

If wide area monitoring is implemented using real detection sensors, then coverage area is increased, but loss of time for installation and maintenance increases

Engineering Contradiction:
Improvemonitoring coverage areaVSAvoidsensor installation and maintenance time
Core Design Contradiction:
Area of stationary objectVSLoss of time

Solution Approach 1:

The patent creates a virtual monitoring network that covers the entire protected region without physical sensor installation. The AI-based prediction system generates pollution concentration data for any location in the coverage area by processing weather, geography, and emission data, eliminating the time-consuming installation and maintenance of physical sensors while maintaining comprehensive monitoring coverage.

Inventive Principle:
Principle #26Copying
