Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If only real-time parking lot information is used for parking space recognition, then the system complexity is low, but the recognition accuracy deteriorates in poor environmental conditions

Engineering Contradiction:
Improveparking space recognition accuracyVSAvoidsystem complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The system performs preliminary action by collecting and storing historical parking lot information in advance under various environmental conditions. This historical data is then utilized during real-time recognition to compensate for poor current environmental conditions, thereby improving recognition accuracy without requiring complex real-time processing infrastructure.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

Historical parking lot information serves as an intermediary element between the current degraded real-time data and the required recognition accuracy. By comparing and fusing historical data with real-time data, the system bridges the gap caused by poor environmental conditions, enabling accurate parking space identification even when real-time imaging conditions are suboptimal.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Speed

If real-time parking space recognition is performed under deteriorated environmental conditions, then the response speed is fast, but the recognition accuracy deteriorates

Engineering Contradiction:
Improverecognition response speedVSAvoidparking space recognition accuracy
Core Design Contradiction:
SpeedVSMeasurement precision

Solution Approach 1:

The system merges real-time parking lot information with historical parking lot information to create a fused dataset for recognition. This combination allows the system to maintain fast real-time response while leveraging historical data to compensate for environmental degradation, thereby achieving both speed and accuracy simultaneously.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The system implements feedback by continuously comparing real-time recognition results with historical data patterns. When environmental conditions deteriorate, the feedback mechanism allows the system to adjust its recognition parameters based on historical success patterns, maintaining accuracy without sacrificing real-time response capability.

Inventive Principle:
Principle #23Feedback

3Ease of operation

If parking space lines are blurred or incomplete due to environmental factors, then the ease of operation is maintained, but the measurement precision deteriorates

Engineering Contradiction:

Solution Approach 1:

The system creates a virtual copy of the parking lot layout by fusing real-time imaging data with historical parking space information. This virtual model allows the system to identify parking spaces even when physical lines are blurred or incomplete, maintaining operational simplicity while achieving accurate detection through data replication and comparison.

Inventive Principle:
Principle #26Copying
