Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional group control host transmits power data to display terminals, then data transmission is achieved, but feedback signals from display terminals are not received in time
Solution Approach 1:
The patent introduces a feedback signal reception module in the group control host that actively receives feedback signals from display terminals. This feedback mechanism enables the host to obtain real-time status information from terminals, resolving the issue of delayed feedback signal reception and enabling closed-loop control for improved reliability.
Solution Approach 2:
The patent employs a communication module as an intermediary between the group control host and display terminals. This intermediary handles signal transmission and reception, ensuring timely delivery of both control commands and feedback signals, thereby reducing feedback delay and improving overall system reliability.
2Productivity
If conventional group control host transmits power data to display terminals, then data transmission is achieved, but real-time data mutual feedback is not realized
Solution Approach 1:
The patent implements a bidirectional communication system where the group control host not only transmits power data to display terminals but also receives feedback signals from them. This real-time feedback loop ensures that no information is lost and enables continuous monitoring and control, improving both productivity and information completeness.
Solution Approach 2:
The patent establishes continuous data exchange between the group control host and display terminals through persistent communication channels. The system maintains ongoing transmission of power data and continuous reception of feedback signals, ensuring uninterrupted information flow and preventing any loss of feedback information.
3Device complexity
If group control device lacks feedback reception capability, then device complexity is reduced, but practicability is reduced
Solution Approach 1:
The patent adds a feedback signal reception module to the group control host, enabling it to receive and process feedback signals from display terminals. This enhancement improves practicability by allowing real-time monitoring and control, while the module is designed to integrate seamlessly into existing control systems, minimizing the increase in overall complexity.
