Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If map layers are selected and combined by users in the conventional environment, then the convenience of map generation is improved, but human errors occur due to use of incompatible map layers from different sensor data versions

Engineering Contradiction:

Improveconvenience of map generationVSAvoidaccuracy of high definition map

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system provides feedback by displaying compatibility information for each map layer to the user. The processor determines whether selected map layers are compatible by comparing sensor data versions and provides this information back to the user interface, allowing users to make informed selections and avoid compatibility errors.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The processor acts as an intermediary between the user and the map layer combination process. It automatically checks compatibility between map layers by comparing sensor data versions and prevents combination of incompatible layers, mediating the user's selection process to ensure reliability.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If compatibility verification is added to the map layer selection process, then the accuracy and safety of high definition maps is improved, but the complexity of the generation process increases

Engineering Contradiction:

Improvesafety of autonomous driving systemVSAvoidcomplexity of map generation process

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs self-service by automatically verifying compatibility of map layers without requiring manual intervention from the user. The processor autonomously compares sensor data versions and determines compatibility, eliminating the need for users to manually verify compatibility while maintaining high reliability.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary compatibility verification before allowing map layer combination. The processor checks whether map layers are compatible by comparing sensor data versions in advance, preventing incompatible combinations from occurring and ensuring safety before the actual map generation process.

Inventive Principle:

Principle #10Preliminary action
