Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If air switch or PLC circuit is used to control turnout power source, then turnout control function is achieved, but construction and maintenance become time-consuming and laborious
Solution Approach 1:
The patent replaces the mechanical air switch system with an electronic control system comprising a relay driving module, relay collection module, and communication module. This substitution eliminates the need for complex mechanical air switch construction while achieving the same power source control function through electronic relays and digital communication, thereby reducing construction time and labor requirements.
Solution Approach 2:
The patent introduces a communication module as an intermediary between the relay driving module and relay collection module, enabling data transmission and coordination without direct mechanical connections. This intermediary approach simplifies the overall system architecture by decoupling control functions and allowing modular construction and maintenance.
2Reliability
If air switch or PLC circuit is used for turnout control, then power source control is achieved, but maintenance and protection become inconvenient
Solution Approach 1:
The patent implements a feedback mechanism where the relay collection module continuously monitors the state of relays and transmits this information through the communication module to external systems. This feedback enables real-time monitoring of system status, facilitating proactive maintenance and quick fault diagnosis, thereby improving both reliability and maintenance convenience compared to traditional air switch systems.
Solution Approach 2:
The electronic control system performs self-diagnosis and state reporting automatically through the relay collection module and communication module, reducing the need for manual inspection and intervention. The system can identify and report faults without human assistance, making maintenance more convenient and improving overall system reliability.
3Ease of repair
If full-electronic control system is implemented, then maintenance becomes easier, but system complexity increases
Solution Approach 1:
The patent divides the control system into distinct functional modules: relay driving module for control signals, relay collection module for state monitoring, and communication module for data transmission. This segmentation allows each module to be independently tested, maintained, and replaced, simplifying maintenance tasks despite the electronic complexity. Each module has a specific function, making fault isolation and repair more straightforward.
4Adaptability or versatility
If traditional relay control is used, then simple structure is maintained, but smart turnout control requirements are not satisfied
Solution Approach 1:
The patent creates a universal control platform that can handle multiple functions: relay control, state monitoring, data communication, and fault diagnosis. The communication module enables the system to interface with various external systems, and the modular architecture allows the same hardware platform to support different control strategies and applications, satisfying smart turnout control requirements while maintaining reasonable complexity through standardization.
