Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple power receiver circuits are connected in parallel to a common transmission line, then the power distribution capacity and versatility are improved, but the difficulty of maintaining consistent line resistance and capacitance increases
Solution Approach 1:
A termination module is introduced as an intermediary device connected to the common transmission line. This module includes adjustable capacitance and resistance elements that act as a mediator to maintain consistent line characteristics despite multiple parallel receivers being connected. The termination module compensates for variations in line resistance and capacitance caused by parallel connections, ensuring stable operation of the PET protocol.
2Ease of operation
If multiple parallel receivers are operated without a termination module, then the ease of operation is improved, but the reliability and safety of power distribution deteriorates due to inability to detect faults and prevent overloads
Solution Approach 1:
The termination module implements feedback mechanisms by monitoring current, voltage, and power levels in the parallel receiver configuration. Communication between receivers and the transmitter is established, allowing the system to detect faults and identify when parameters fall outside predetermined limits. This feedback enables the transmitter to inhibit power when necessary, ensuring safe operation while maintaining ease of use.
3Reliability
If a termination module with adjustable capacitance and resistance is added, then the reliability and control of power distribution are improved, but the device complexity increases
Solution Approach 1:
The termination module is designed to perform multiple functions within a single integrated device. It provides adjustable capacitance and resistance for maintaining line characteristics, fault detection through monitoring, communication interface for receiver-transmitter coordination, and power inhibition control. This multi-functionality reduces the need for separate components and justifies the added complexity by delivering comprehensive power distribution control and safety.
