Engineering Contradiction Analysis
1Area of stationary object
If power is supplied via coaxial cable to sensor units, then installation space is reduced and power transmission is achieved, but signal leakage occurs and transmission quality deteriorates
Solution Approach 1:
The control unit predicts power consumption changes before they occur by monitoring control instructions, and proactively adjusts the equalizer coefficients in advance to compensate for upcoming signal attenuation, preventing transmission quality deterioration before it happens
Solution Approach 2:
The system continuously monitors power consumption states and adjusts equalizer coefficients dynamically based on feedback from power consumption changes, maintaining optimal signal transmission quality under varying power conditions
2Adaptability or versatility
If driving devices in sensor unit are operated to provide various functions, then functionality is improved, but power consumption varies causing voltage level changes and communication errors
Solution Approach 1:
The control unit analyzes incoming control instructions to predict future power consumption changes before they occur, and preemptively adjusts equalizer coefficients to compensate for anticipated signal attenuation, preventing communication errors before they happen
Solution Approach 2:
The equalizer coefficients are dynamically adjusted in real-time based on predicted power consumption states, allowing the system to adapt to varying functionality requirements while maintaining transmission reliability
3Quantity of substance
If multiple sensor units are connected and used simultaneously, then system capability is enhanced, but power consumption per unit is limited thus restricting available functions
Solution Approach 1:
The control unit predicts power consumption for each sensor unit based on control instructions before executing operations, enabling proactive power management that allows multiple units to operate with higher power consumption levels without causing transmission errors
Solution Approach 2:
The system changes the equalizer coefficients parameter dynamically based on predicted power consumption states, allowing multiple sensor units to operate simultaneously with enhanced functionality while maintaining transmission quality through adaptive compensation
