Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If power line communication is used to transmit data and power on a common power distribution line, then communication infrastructure cost is reduced, but data transmission reliability deteriorates due to noise from load changes and switching on the energy distribution grid
Solution Approach 1:
The communication function is segmented from the power transmission function by introducing a separate communication line connected to the signal terminal. This allows data transmission to occur independently from the noisy power distribution line, while still utilizing the existing power infrastructure for power delivery.
Solution Approach 2:
A communication line acts as an intermediary between the power distribution system and the data communication needs. This intermediary provides a dedicated pathway for data transmission that is isolated from the electrical noise and disturbances present on the power distribution line.
2Adaptability or versatility
If dedicated PLC chipsets are used for power line communication, then data transmission capability is achieved, but device complexity and cost increase due to complex circuitry needed for noise filtering and signal extraction
Solution Approach 1:
The data transmission function is extracted from the power distribution line and assigned to a separate communication line. This extraction eliminates the need for complex PLC chipsets and noise filtering circuitry, as the communication line provides a clean signal path independent of power line disturbances.
Solution Approach 2:
Instead of using complex PLC technology to embed data in power signals, the invention creates a separate copy of the communication function through a dedicated communication line. This simpler approach achieves the same data transmission goal without requiring sophisticated signal processing hardware.
3Duration of action of stationary object
If the application device operates continuously in AC power mode, then power availability is maintained, but noise from AC power transmission corrupts data signals during communication
Solution Approach 1:
The system uses periodic switching between AC power mode and battery power mode to create distinct time slots for power transmission and data communication. During AC power mode, power is transmitted; during battery power mode, data communication occurs without AC power noise interference.
Solution Approach 2:
The battery is charged in advance during AC power mode when power is abundant, preparing stored energy for the subsequent communication phase. This preliminary charging action enables noise-free data transmission during battery-powered communication periods.
