Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Area of stationary object

If cameras are installed outside the vehicle to capture blind spots, then the coverage area is improved, but the installation position accuracy deteriorates

Engineering Contradiction:

Improvecoverage areaVSAvoidinstallation position accuracy

Core Design Contradiction:

Area of stationary objectVSManufacturing precision

Solution Approach 1:

The system automatically performs road calibration and camera position correction without requiring manual intervention or professional calibration services. The vehicle itself generates the calibration data by capturing images during normal driving, and the system automatically processes these images to correct camera positions, enabling self-service calibration that eliminates the need for external calibration equipment or expert technicians.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary road calibration by capturing reference images at predetermined positions before final camera position determination. This preliminary action of collecting calibration data during normal driving allows the system to pre-establish the relationship between camera positions and actual road features, which is then used to correct installation errors and improve positioning accuracy.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If traditional road calibration methods are used, then measurement accuracy is improved, but the complexity of the calibration process increases

Engineering Contradiction:

Improvemeasurement accuracyVSAvoidcalibration process complexity

Core Design Contradiction:

Measurement precisionVSDevice complexity

Solution Approach 1:

The system extracts the road calibration function from complex professional calibration equipment and integrates it into the vehicle's existing camera system. By utilizing the vehicle's own cameras to capture calibration images and process correction data, the system removes the need for external calibration devices, reducing overall system complexity while maintaining measurement accuracy through software-based correction algorithms.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system replaces mechanical calibration equipment and manual adjustment mechanisms with software-based image processing and automated correction algorithms. Instead of using physical calibration tools and manual camera positioning, the system captures images during driving and uses computational methods to determine and correct camera positions, substituting mechanical complexity with software intelligence.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If the vehicle stops for road calibration, then calibration accuracy is improved, but the productivity decreases

Engineering Contradiction:

Improvecalibration accuracyVSAvoidcalibration efficiency

Core Design Contradiction:

Measurement precisionVSProductivity

Solution Approach 1:

The system transforms the calibration process from a static, stopped-vehicle operation to a dynamic, moving-vehicle operation. By capturing calibration images while the vehicle is in motion during normal driving, the system allows calibration to occur dynamically without requiring the vehicle to stop, thereby maintaining calibration accuracy while significantly improving productivity and eliminating time loss.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system enables continuous calibration data collection during normal driving operations rather than requiring intermittent stopping for calibration. The vehicle continuously captures road images that can be used for calibration purposes, maintaining the continuity of useful action (driving) while simultaneously performing the calibration function, thus eliminating downtime and improving overall productivity.

Inventive Principle:

Principle #20Continuity of useful action
