Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If wheel type identification is not implemented, then the system structure remains simple, but vehicle control cannot be properly adjusted according to different wheel characteristics
Solution Approach 1:
The transmitter automatically identifies the wheel type by measuring the inductance of the metal member (wheel) itself, without requiring external input or manual configuration. The system uses the wheel's own electromagnetic properties to generate wheel identification information, enabling self-service adaptation.
Solution Approach 2:
The patent replaces manual or mechanical wheel type identification methods with electromagnetic induction measurement. The inductance measuring unit uses electromagnetic fields to detect the magnetic permeability characteristics of the wheel material, substituting physical contact or manual input with non-contact electromagnetic sensing.
2Measurement precision
If inductance measuring unit is added to identify wheel type, then wheel type identification becomes possible, but the device complexity increases
Solution Approach 1:
The metal member (wheel) serves multiple functions: it is both the structural component of the wheel and the sensing target for inductance measurement. The transmitter integrates multiple functions including data generation, inductance measurement, wheel type determination, and wireless transmission, reducing the need for separate dedicated components.
Solution Approach 2:
The system identifies wheel type by measuring changes in the electromagnetic parameter (inductance) of the metal member. Different wheel materials (steel, aluminum, alloy) exhibit different magnetic permeability, causing distinct inductance values that enable accurate material identification through parameter variation detection.
3Adaptability or versatility
If wheel identification information is transmitted, then the receiver can set appropriate thresholds, but the data transmission requires additional information processing
Solution Approach 1:
The transmitter performs wheel type identification and generates wheel identification information in advance, before the receiver needs to set thresholds. This preliminary action ensures that the receiver receives ready-to-use identification data, eliminating the need for complex real-time analysis or additional sensing at the receiver end.
