Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional mapping technology is used for navigation, then navigation coverage is improved, but data storage requirements and processing complexity increase
Solution Approach 1:
The patent extracts and utilizes wheel dynamics information (spin and rotation detection) from the complex sensor data stream to derive navigation decisions, separating the critical navigational cues from the overwhelming volume of traditional mapping data, thereby reducing processing complexity while maintaining navigation accuracy
Solution Approach 2:
The patent replaces reliance on traditional mapping data processing with a mechanics-based approach that analyzes wheel dynamics (spin and rotation) to determine navigational actions, substituting complex data processing with physical principle-based decision making
2Measurement precision
If wheel spin detection is added to navigation system, then navigation accuracy is improved, but system complexity increases
Solution Approach 1:
The patent employs machine learning models that automatically learn to detect wheel spin and rotation from image sequences, allowing the system to self-improve detection accuracy without requiring manual programming of complex detection algorithms, thereby managing system complexity through automated learning
