Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If perception algorithms are used for autonomous driving functions, then the vehicle can provide assisted driving services (AEB, ACC, NOA, HWP), but the performance is affected by hardware and environmental changes causing the functions to fail to meet functional safety requirements

Engineering Contradiction:

Improveassisted driving function coverageVSAvoidfunctional safety requirement compliance

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies preliminary action by performing perception failure simulation before actual deployment. The system pre-generates failed perception results through simulation and uses these to verify vehicle function reliability in advance, allowing developers to identify and fix potential safety issues before the system operates in real-world conditions.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces an intermediary verification system that sits between the perception algorithm and the vehicle control functions. This verification system uses simulated failed perception results to test and validate whether the vehicle functions can handle perception failures safely, acting as a mediator to ensure functional safety requirements are met.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If perception algorithms are deployed in real-world conditions, then the system can operate with actual sensor data, but hardware and environmental changes cause the perception algorithm performance to deteriorate

Engineering Contradiction:

Improvereal-world operation capabilityVSAvoidperception algorithm accuracy

Core Design Contradiction:

Ease of operationVSMeasurement precision

Solution Approach 1:

The patent applies parameter changes by systematically varying perception algorithm parameters under different simulated failure conditions. By testing with modified perception results (simulating hardware and environmental changes), the system identifies parameter adjustments that maintain acceptable performance across diverse operating conditions.

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The system performs preliminary testing with simulated perception failures before real-world deployment. By pre-identifying how the perception algorithm degrades under various hardware and environmental changes through simulation, developers can optimize the algorithm and select robust parameters before encountering actual real-world variations.

Inventive Principle:

Principle #10Preliminary action

3Productivity

If the vehicle function is verified with normal perception results, then the basic functionality can be confirmed, but the tolerance to perception algorithm performance degradation cannot be assessed

Engineering Contradiction:

Improveverification efficiencyVSAvoidperception failure tolerance assessment

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent applies partial action by separating verification into two stages: first verifying basic functionality with normal perception results, then performing additional targeted verification with simulated failed perception results. This approach efficiently confirms basic operations while specifically addressing perception failure tolerance without requiring complete re-verification of all functions.

Inventive Principle:

Principle #16Partial or excessive action

Solution Approach 2:

The verification process is segmented into multiple independent verification scenarios. Each scenario tests specific vehicle functions under particular perception failure conditions. This segmentation allows efficient verification of basic functionality separately from failure tolerance assessment, enabling targeted testing that improves overall verification efficiency.

Inventive Principle:

Principle #1Segmentation
