Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If GPS systems or physical wires are used to check integrity, then integrity detection capability is achieved, but system complexity increases and flexibility decreases
Solution Approach 1:
The patent replaces complex mechanical systems (GPS receivers, physical wire connections) with simple wireless beacon devices that transmit identification signals. This substitution maintains integrity detection capability while significantly reducing system complexity, as beacons are self-contained units that require no external infrastructure.
Solution Approach 2:
The patent uses multiple identical beacon devices placed on different cars, each broadcasting its unique identification. This copying approach allows the system to detect integrity by verifying the presence of expected beacon signals, simplifying the overall system architecture compared to centralized GPS or wire-based solutions.
2Reliability
If traditional systems are used, then integrity checking is possible, but adaptability to reconfiguration is poor
Solution Approach 1:
The patent creates a dynamic system where beacons can be easily added or removed from cars based on reconfiguration needs. The CPU adapts by receiving and processing signals from whatever beacons are currently present, allowing the system to flexibly accommodate changes in vehicle composition without requiring system reconfiguration.
Solution Approach 2:
The beacon device is designed as a universal component that can be placed on any car in the guided vehicle formation. Each beacon provides the same function (broadcasting identification), and the CPU handles any combination of beacons, making the system universally adaptable to different configurations.
3Measurement precision
If beacons with amplifiers are used, then signal transmission range is extended for better detection, but device complexity increases
Solution Approach 1:
The patent combines the beacon, amplifier, and antenna into a single integrated device. This merging eliminates the need for separate components and their associated connections, reducing installation complexity while maintaining extended signal transmission capability through the built-in amplifier.
Solution Approach 2:
The beacon device is self-contained with integrated amplification and transmission capabilities, requiring no external infrastructure or complex installation. The device automatically broadcasts its signal and the CPU automatically detects and processes it, simplifying both deployment and operation.
