Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If real-time monitoring of vehicle following distance is implemented, then fleet safety and accident prevention are improved, but system complexity and computational requirements increase

Engineering Contradiction:

Solution Approach 1:

The patent creates a virtual copy of the real-world driving environment using rendered images from virtual camera perspectives. These synthetic images replicate actual driving scenarios including vehicle positions, road conditions, and environmental factors, allowing the AI model to train on comprehensive data without requiring parallel physical monitoring infrastructure for every training scenario.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system performs preliminary action by pre-rendering and storing multiple images representing various driving scenarios, vehicle positions, and environmental conditions in a database. This pre-computed training data is prepared in advance, allowing the AI model to be trained beforehand and deployed for real-time monitoring without complex computational processing during actual fleet operations.

Inventive Principle:
Principle #10Preliminary action

2Measurement precision

If accurate distance determination is achieved through multiple image attributes, then measurement precision improves, but processing time and computational load increase

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The patent calculates and stores multiple image attributes (vehicle position, size, orientation, distance) during the offline rendering and training phase. By pre-computing these attributes and storing them with corresponding images in the database, the system avoids real-time calculation of multiple attributes during actual distance determination, significantly reducing processing time while maintaining high measurement precision.

3Measurement precision

If comprehensive training data is generated through virtual environment simulation, then model accuracy improves, but data processing and storage requirements increase

Engineering Contradiction:

Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent applies local quality by selectively rendering and storing images with specific characteristics relevant to tailgating detection. Rather than uniformly generating all possible driving scenarios, the system focuses on creating training data with varying vehicle distances, speeds, and positions that are locally optimized for detecting tailgating conditions. This targeted approach improves model accuracy for the specific application while reducing unnecessary data volume.

Inventive Principle:
Principle #3Local quality

AI summary

Systems, methods, models, and training data for models are discussed, for determining vehicle positioning, and in particular identifying tailgating. Simulated training images showing vehicles following other vehicles, under various conditions, are generated using a virtual environment. Models are trained to determine following distance between two vehicles. Trained models are used in detection of tailgating, based on determined distance between two vehicles. Results of tailgating are output to warn a driver, or to provide a report on driver behavior. Following distance over time is determined, and simplified following distance data is generated for use at a management device.
