Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If satellite navigation networks are used for localization, then positioning accuracy is improved, but system reliability deteriorates in network-restricted environments

Engineering Contradiction:

Improvepositioning accuracyVSAvoidsystem reliability

Core Design Contradiction:

Measurement precisionVSReliability

Solution Approach 1:

The system transitions from satellite-based positioning parameters to visual feature matching parameters. By changing the fundamental measurement parameters from satellite signal coordinates to image feature vectors extracted from visual landmarks, the system achieves reliable localization in network-restricted environments while maintaining positioning accuracy through sophisticated image processing and feature comparison algorithms

Inventive Principle:

Principle #35Parameter changes

Solution Approach 2:

The patent replaces the satellite-based electromagnetic positioning system with a visual-mechanical feature matching system. Instead of relying on satellite signals, the system uses image sensors to capture visual landmarks, extracts features from these images, and matches them against stored map features to determine position, thereby substituting the satellite navigation mechanism with a visual recognition mechanism that operates independently of network infrastructure

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Speed

If satellite navigation networks are used for localization, then initial positioning speed is improved, but adaptability deteriorates in network-restricted conditions

Engineering Contradiction:

Improvepositioning speedVSAvoidenvironmental adaptability

Core Design Contradiction:

SpeedVSAdaptability or versatility

Solution Approach 1:

The system performs preliminary actions by pre-capturing and storing multiple images of known landmarks and their associated feature vectors in a database before actual localization is needed. This pre-processing and pre-storing of visual reference data enables rapid adaptation to network-restricted environments, as the system can immediately begin feature matching without requiring network access to acquire reference information

Inventive Principle:

Solution Approach 2:

The system changes from satellite-based positioning parameters to visual feature matching parameters. By changing the fundamental measurement parameters from satellite signal coordinates to image feature vectors extracted from visual landmarks, the system achieves reliable localization in network-restricted environments while maintaining positioning accuracy through sophisticated image processing and feature comparison algorithms

Inventive Principle:
