Engineering Contradiction Analysis
1Reliability
If analog signals are used to transmit rotational data from tachometer to central processing unit, then the system can transmit rotational speed measurements, but the processing performance is reduced and the signal is susceptible to noise
Solution Approach 1:
The patent replaces the analog signal transmission system with a digital communication system. The encoder component converts rotational position measurements into digital data packets that are transmitted via digital communication protocols (such as CAN bus, Ethernet, or wireless digital protocols) instead of analog voltage signals. This substitution eliminates analog noise susceptibility and improves processing performance while maintaining the essential function of transmitting rotational speed data from the tachometer to the central processing unit.
Solution Approach 2:
The patent changes the signal parameter from analog voltage to digital data packets. The encoder component samples the rotational position and encodes it into digital values representing rotational speed and acceleration. This parameter change from continuous analog signals to discrete digital data improves signal integrity, reduces noise susceptibility, and enhances processing performance in the central processing unit.
2Measurement precision
If digital encoding is implemented for rotational data, then accuracy and noise resistance improve, but device complexity increases
Solution Approach 1:
The patent merges the encoder component with the existing tachometer assembly. The encoder integrates digital signal processing capabilities directly into the tachometer unit, combining the rotational sensing function with digital encoding and transmission functions. This integration reduces overall system complexity by eliminating separate analog-to-digital conversion components and simplifying the signal path while maintaining high measurement precision.
3Reliability
If distributed sensors are synchronized using digital data packets, then false failure alerts are reduced and maintenance efficiency improves, but the system complexity increases
Solution Approach 1:
The patent implements a feedback mechanism where the central processing unit receives synchronized digital data packets from multiple distributed sensors, compares the rotational data across sensors, and provides feedback to validate measurements. This feedback loop enables the system to detect and eliminate false failure alerts by cross-validating data from multiple sensor sources, improving reliability while managing network complexity through intelligent data processing.
