Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired communication with cables and connectors is used between rail vehicles, then communication can be established, but the system becomes susceptible to contact problems due to dirt, moisture, and mechanical stresses
Solution Approach 1:
The patent replaces the mechanical cable and connector system with a wireless communication system using radio waves. The wired mechanical connection (cables and connectors) is substituted by electromagnetic field-based wireless transmission, eliminating physical contact points that are vulnerable to environmental factors and mechanical stress.
Solution Approach 2:
The patent introduces wireless radio communication as an intermediary medium to transfer data between rail vehicles. Instead of direct physical cable connections, radio waves serve as the intermediary carrier signal, allowing data transmission without physical contact and thus avoiding issues with dirt, moisture, and vibrations.
2Reliability
If cables are used for communication between rail vehicles, then data transmission is possible, but material costs and installation costs increase
Solution Approach 1:
The patent replaces the mechanical cable system with wireless communication technology, eliminating the need for copper cables, connectors, and associated installation infrastructure. This substitution removes material costs for cables and reduces installation complexity, while maintaining communication capability.
Solution Approach 2:
The patent extracts and removes the cable and connector components from the communication system. By taking out the physical wiring infrastructure entirely and replacing it with wireless transmission, the system eliminates material costs and installation requirements while preserving the essential data transmission function.
3Reliability
If directed radio links are used for communication between adjacent rail vehicles, then communication reliability improves, but device complexity increases due to multiple transmitting and receiving devices
Solution Approach 1:
The patent implements multi-functional transmitting and receiving devices that can operate in both directed and omnidirectional modes. Each device serves multiple purposes: it can communicate with adjacent vehicles using directed links and simultaneously provide communication within the rail vehicle using omnidirectional links, reducing the need for separate dedicated devices for each function.
Solution Approach 2:
The patent combines directed and omnidirectional communication capabilities into a unified wireless system. By merging these different communication modes into integrated transmitting and receiving devices, the system achieves reliable communication both between adjacent vehicles and within vehicles without requiring entirely separate device sets, thus managing complexity.
