Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If a trained machine learning model is used to detect visual pollution from captured images or video footages, then detection accuracy is improved, but the model becomes cumbersome and incapable of functioning in real-time

Engineering Contradiction:
Improvedetection accuracyVSAvoidreal-time capability
Core Design Contradiction:
Measurement precisionVSProductivity

Solution Approach 1:

The patent segments the visual pollution detection task into multiple specialized expert models, each trained to detect specific types of visual pollution (e.g., billboards, signage, construction sites). These segmented expert models are then integrated through an ensemble approach, allowing the system to maintain high detection accuracy for different pollution types while improving overall processing efficiency and real-time capability.

Inventive Principle:
Principle #1Segmentation

2Measurement precision

If human inspectors are sent throughout cities/towns to detect visual pollution, then detection thoroughness is improved, but time, labor, and resource consumption increase

Engineering Contradiction:
Improvedetection thoroughnessVSAvoidtime and resource consumption
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent replaces the mechanical system of human inspectors physically traversing cities with an automated computer vision system. The system uses trained machine learning models to process captured images and video footages, automatically detecting visual pollution elements without requiring human labor for data collection, thereby eliminating time and resource consumption associated with manual inspection while maintaining or improving detection thoroughness.

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

3Measurement precision

If CCTV cameras are installed in specific places to detect visual pollution, then detection coverage in high-probability areas is improved, but areas out of reach remain un-examinable

Engineering Contradiction:
Improvedetection coverageVSAvoidarea coverage
Core Design Contradiction:
Measurement precisionVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal detection system using trained machine learning models that can be deployed across diverse locations and conditions. The models are trained on varied datasets representing different urban environments, allowing the same system to adaptively detect visual pollution in any area where images or video footages can be captured, whether from fixed cameras, mobile devices, or aerial platforms, thereby achieving both targeted coverage and broad adaptability.

Inventive Principle:
Principle #6Universality (Multi-functionality)

4Measurement precision

If existing machine learning models are used for visual pollution detection, then detection capability is improved, but false positives increase and throughput becomes unsatisfactory

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSReliability

Solution Approach 1:

The patent merges multiple specialized expert models into an ensemble system where each model contributes to the final detection decision. By combining the predictions of multiple models that have been trained on different aspects of visual pollution detection, the system achieves higher reliability and reduces false positives through consensus decision-making, while maintaining satisfactory throughput via efficient model integration and processing.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Provided are computer-implemented technologies of identifying visual pollutions. The technologies include training expert models based on an enhanced knowledge distillation paradigm in which a student model learns from a number of teacher models via a customized training approached specifically for achieving efficiency and effectiveness, quality-controlling and fine-tuning the trained expert model in a production environment via continuous training under newly incorporated training data and object classifications and factoring feedbacks of the detection result of the model on new training data and/or new object classifications, deploying and applying the expert model in detecting, tracking, logging, counting, and reporting a set of visual pollution elements in an environment where visual pollutions are to be detected.
