Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If RF signals are used to communicate with rail appliances, then wireless communication capability is achieved, but communication reliability deteriorates due to interference from other wireless signals in urban areas
Solution Approach 1:
The patent introduces a conductive pathway (the rail itself) as an intermediary medium for data transmission. Instead of directly transmitting RF signals between the tower and rail appliances, the system uses the rail as a conductor to carry electrical signals, effectively mediating the communication process and avoiding RF interference from other wireless signals in urban environments.
Solution Approach 2:
The patent replaces the electromagnetic field-based RF communication system with an electrical conduction-based system. By substituting wireless electromagnetic signals with wired electrical signals through the conductive rail pathway, the system eliminates the interference problems inherent in wireless RF communication while maintaining communication functionality.
2Ease of operation
If RF communication equipment is deployed in the tower and rail appliances, then wireless communication is enabled, but system cost increases
Solution Approach 1:
The patent makes the existing rail infrastructure serve multiple functions: it continues to guide rail vehicles while simultaneously functioning as a conductive pathway for data communication. This eliminates the need for separate dedicated communication infrastructure, reducing system cost and complexity.
Solution Approach 2:
The system utilizes the rail's inherent electrical conductivity property to provide communication functionality without requiring additional specialized equipment. The rail essentially serves itself by performing both its primary function of supporting vehicle movement and its secondary function of transmitting communication signals.
3Ease of operation
If specialized RF communication equipment is provided with rail appliances, then wireless communication is achieved, but device complexity and cost increase
Solution Approach 1:
The conductive rail pathway serves as an intermediary that eliminates the need for complex RF communication equipment at the rail appliance level. By using the rail as the communication medium, the appliance only needs basic electrical connection capabilities rather than sophisticated wireless transceivers.
Solution Approach 2:
The patent changes the communication parameter from wireless electromagnetic frequency transmission to wired electrical conduction. This fundamental parameter change simplifies the appliance equipment requirements, as the appliances only need to interface with the existing conductive rail infrastructure rather than implementing complex RF communication protocols.
