Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If magnet members with different magnetic properties and intervals are used, then rotation attribute detection precision is improved, but device complexity increases

Engineering Contradiction:
Improverotation attribute detection precisionVSAvoiddevice complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The detection system is segmented into multiple magnet members with different magnetic properties (first magnetic property and second magnetic property) arranged at different intervals. Each magnet member contributes to detecting different aspects of rotation attributes, enabling precise detection through combined information from multiple segmented magnetic sources

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different regions of the second housing contain magnet members with locally optimized magnetic properties. The first magnet member has a first magnetic property suitable for detecting certain rotation characteristics, while the second magnet member has a second magnetic property for detecting other characteristics, allowing each local region to contribute its specialized detection capability

Inventive Principle:
Principle #3Local quality

2Measurement precision

If multiple magnet members with different magnetic properties are used, then detection accuracy is improved, but manufacturing cost increases

Engineering Contradiction:
Improvedetection accuracyVSAvoidmanufacturing cost
Core Design Contradiction:
Measurement precisionVSEase of manufacture

Solution Approach 1:

The patent changes magnetic parameters (magnetic strength, polarity, interval) of different magnet members to achieve diverse detection capabilities. By varying these parameters rather than using identical magnet members, the system achieves high detection accuracy while potentially using standard magnet manufacturing processes for each type

Inventive Principle:
Principle #35Parameter changes

3Measurement precision

If magnet members are placed at different intervals, then rotation speed detection is improved, but device structure becomes more complex

Engineering Contradiction:
Improverotation speed detectionVSAvoiddevice structure
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The patent introduces the dimensional aspect of interval spacing as a new degree of freedom for detection optimization. By placing magnet members at different intervals (different spatial dimensions) rather than uniformly, the system can detect rotation speed through the temporal sequence of magnetic field variations as the housing rotates, converting spatial arrangement into temporal detection signals

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
