Engineering Contradiction Analysis
1Reliability
If fixed transmission speed is used in single-wire communication, then device complexity is reduced, but communication reliability deteriorates due to inability to adapt to varying conditions
Solution Approach 1:
The patent implements dynamic transmission speed adjustment by monitoring signal properties (rise time, fall time, pulse width) and adapting the transmission speed accordingly. The system transitions from fixed-speed communication to adaptive speed communication, where the master device adjusts timing parameters based on measured signal characteristics, thereby improving reliability without requiring complex hardware modifications.
Solution Approach 2:
The patent changes the timing parameters of the communication protocol based on measured signal properties. Specifically, it adjusts the minimum pulse width, inter-pulse spacing, and sampling timing based on the actual rise time and fall time of received signals, allowing the system to adapt to varying communication conditions and improve reliability through parameter optimization.
2Productivity
If higher transmission speed is used, then productivity is improved, but communication reliability deteriorates due to increased errors
Solution Approach 1:
The patent implements a feedback mechanism where the master device monitors the rise time and fall time of received sensing signals, compares these measurements against threshold values, and adjusts the transmission speed accordingly. This closed-loop control allows the system to optimize transmission speed dynamically, achieving high productivity when conditions permit while maintaining reliability by reducing speed when signal quality degrades.
3Reliability
If adaptive speed adjustment is implemented, then communication reliability is improved, but device complexity increases due to additional signal analysis requirements
Solution Approach 1:
The patent implements self-service by having the communication protocol itself carry the necessary timing information. The sensing signal's rise time and fall time directly indicate the appropriate transmission speed, eliminating the need for separate control messages or complex handshaking protocols. The system uses the signal properties themselves as the control mechanism, simplifying the overall complexity while maintaining adaptability.
