Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If additional sensor elements are used for object detection and classification, then measurement precision may be improved, but device complexity increases

Engineering Contradiction:
Improveobject detection precisionVSAvoidsensor system complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The radar sensor unit is designed to perform multiple functions including object detection, object classification, depth determination, and wall type classification using a single sensor system, eliminating the need for multiple specialized sensor elements while maintaining comprehensive diagnostic capabilities

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

Solution Approach 2:

The diagnostic module analyzes different parameters from the radar data (signal strength, time of flight, frequency characteristics) to extract multiple types of information including object presence, classification, depth, and wall type, achieving comprehensive detection through parameter analysis rather than multiple sensors

Inventive Principle:
Principle #35Parameter changes

2Measurement precision

If additional sensor information is integrated for object classification, then object type identification accuracy may improve, but the diagnostic process becomes more complex

Engineering Contradiction:

Solution Approach 1:

The patent extracts and analyzes specific characteristics from the radar data signals (such as reflection patterns, signal strength variations, and time delays) to classify objects and determine wall types, achieving accurate classification by focusing on key extracted features rather than processing all possible sensor data

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The diagnostic module serves as an intermediary that processes radar data to determine wall type first, then uses this wall type information to interpret object characteristics, creating a hierarchical processing approach that simplifies the overall classification task by breaking it into manageable steps

Inventive Principle:
Principle #24Intermediary (Mediator)

3Adaptability or versatility

If multiple sensor types are used for comprehensive wall diagnosis, then diagnostic completeness improves, but ease of operation decreases

Engineering Contradiction:
