Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional high voltage test systems are used, then basic testing function is provided, but flexibility and modular construction are lacking
Solution Approach 1:
The high voltage test system is divided into separate modular components: a wireless controller unit and a high voltage power supply unit. The controller contains a single board PC, wireless interface, and user interface, while the power supply contains the high voltage generation circuitry. This segmentation allows independent configuration and replacement of modules to achieve desired flexibility without increasing overall system complexity.
Solution Approach 2:
The wireless controller is designed with universal functionality to control different high voltage test configurations. The single board PC runs configurable software that can adapt to various test requirements, and the wireless interface enables the same controller to manage multiple power supply units or different test setups, providing versatility without requiring complex dedicated systems for each configuration.
2Ease of operation
If wireless control is implemented, then portability and safety are improved, but network dependency is introduced
Solution Approach 1:
The system continuously monitors the wireless network connection status and provides feedback to both the controller and the user interface. When connection quality degrades or is lost, the system automatically detects this through the wireless interface and can trigger alerts or switch to alternative operating modes, ensuring reliable operation despite network variability.
Solution Approach 2:
The system is designed with redundancy and error handling capabilities that prepare for potential network failures before they occur. The controller includes buffer memory for command queuing, error correction protocols in the wireless communication, and safety interlocks that can maintain safe states even during communication interruptions, cushioning against the reliability issues introduced by wireless networking.
3Object-affected harmful factors
If remote operation is enabled, then operator safety is improved, but control response time may be increased
Solution Approach 1:
The system replaces physical wired connections and direct operator proximity with wireless electronic communication. This substitution allows the operator to control the high voltage system from a safe distance while maintaining rapid response times through digital signal transmission, which is faster than mechanical or manual control methods would allow.
Solution Approach 2:
The wireless controller pre-processes control commands and maintains a ready state for immediate execution. The single board PC and wireless interface are continuously powered and monitored, so when commands are received, they can be executed immediately without delay for physical connection establishment or manual intervention, minimizing response time while keeping the operator remotely safe.
