Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If traditional methods are used to process road element information in real-time, then comprehensive information can be captured, but processing efficiency and resource consumption are insufficient

Engineering Contradiction:
Improveprocessing efficiencyVSAvoidresource consumption
Core Design Contradiction:
ProductivityVSUse of energy by moving object

Solution Approach 1:

The patent segments road element information processing into multiple token types (classification tokens, location tokens, behavioral tokens). Each token represents a specific aspect of the road element, allowing the system to process only relevant information segments rather than treating all data uniformly, thereby improving processing efficiency while reducing unnecessary resource consumption.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent extracts and processes only the most relevant tokens for each road element based on the driving scenario. By identifying and focusing on critical information (such as behavioral tokens for dynamic objects or location tokens for spatial relationships), the system eliminates processing of redundant data, achieving both high processing efficiency and reduced resource consumption.

Inventive Principle:
Principle #2Taking out (Extraction)

2Reliability

If all tokens representing road elements are processed in detail, then comprehensive understanding is achieved, but processing complexity and resource allocation increase

Engineering Contradiction:
Improveaccuracy of road element processingVSAvoidprocessing complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent dynamically adjusts which tokens are processed based on the driving scenario and context. The system can adaptively select and prioritize tokens relevant to the current situation (e.g., focusing on behavioral tokens during high-risk scenarios or location tokens during navigation), maintaining high processing accuracy while reducing overall processing complexity through context-aware selective processing.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

Different token types receive different processing priorities and computational resources based on their relevance to the driving task. Classification tokens may receive simpler processing while behavioral tokens requiring prediction receive more sophisticated analysis. This localized quality approach ensures accurate processing of critical information while reducing complexity for less critical data.

Inventive Principle:
Principle #3Local quality

3Measurement precision

If multiple tokens per road element are used to represent different attributes, then granular information is obtained, but data volume and processing load increase

Engineering Contradiction:
Improvegranularity of road element representationVSAvoiddata volume
Core Design Contradiction:
Measurement precisionVSQuantity of substance

Solution Approach 1:

The patent applies partial processing by selecting and processing only the necessary subset of tokens for each driving scenario. Rather than processing all tokens uniformly, the system performs partial action on the most relevant tokens (e.g., processing behavioral tokens for dynamic objects while using simpler processing for static elements), achieving sufficient measurement precision without the full data volume burden.

Inventive Principle:
Principle #16Partial or excessive action

Solution Approach 2:

The token system is designed to be universal and multi-functional, where the same token structure can represent different aspects of road elements depending on the context. This allows the system to achieve granular representation when needed while consolidating data representation when full granularity is not required, effectively managing data volume while maintaining measurement precision on demand.

Inventive Principle:
Principle #6Universality (Multi-functionality)
