VSEngineering Contradiction Analysis

1Productivity

If theoretical simulation tests are used for autonomous vehicle lane change capability, then test efficiency is improved, but test accuracy and realism deteriorate

Engineering Contradiction:
Improvetest efficiencyVSAvoidtest accuracy
Core Design Contradiction:
ProductivityVSMeasurement precision

Solution Approach 1:

The patent creates a physical test environment that copies real road conditions, including multiple lanes with warning lines, adjustment areas, and actual traffic scenarios. This physical copy allows autonomous vehicles to be tested in conditions that closely resemble real-world driving, thereby improving test accuracy while maintaining controlled test efficiency through standardized track designs.

Inventive Principle:

2Measurement precision

If real road tests are conducted for autonomous vehicle performance validation, then test accuracy is improved, but safety risks increase

Engineering Contradiction:
Improvetest accuracyVSAvoidsafety risks
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a dedicated test road as an intermediary environment between theoretical simulation and real road testing. This intermediate physical test track provides a controlled setting with standardized lanes, warning lines, and adjustment areas that simulate real driving conditions without the full risks of public roads, thereby maintaining test accuracy while reducing safety risks.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The test road design includes preparation areas and adjustment zones that allow autonomous vehicles to be properly configured and tested before entering more challenging test sections. This progressive testing approach cushions against potential failures by ensuring vehicles are adequately prepared and monitored throughout the testing process.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

3Reliability

If standardized test roads with multiple test areas are implemented, then test reliability is improved, but device complexity increases

Engineering Contradiction:
Improvetest reliabilityVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The test road is segmented into distinct functional areas including preparation areas, adjustment areas, and multiple test sections with specific purposes such as lane change testing, overtaking testing, and merging testing. This segmentation allows each area to be optimized for its specific function while maintaining overall system reliability through standardized designs that can be replicated and managed systematically.

Inventive Principle:
Principle #1Segmentation
