Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If nodes in non-network positioning system cannot communicate with each other, then system deployment is simple and extensible, but automatic diagnosis of node failures becomes impossible
Solution Approach 1:
The patent introduces a server as an intermediary that collects signal data from multiple data acquisition terminals. The server performs the node state detection by comparing received signal data with standard signal feature information, enabling automatic diagnosis without requiring direct communication between nodes. This mediator approach resolves the contradiction by allowing centralized automation while preserving the decentralized node architecture.
Solution Approach 2:
The system implements feedback by having data acquisition terminals continuously receive signal data from nodes and send it to the server. The server compares this feedback data with standard signal features and determines node running states, creating a closed-loop monitoring system that enables automatic diagnosis without changing the node communication architecture.
2Device complexity
If artificial maintenance is used for node state diagnosis, then system architecture remains simple, but diagnosis efficiency and timeliness deteriorate
Solution Approach 1:
The system enables self-service by implementing automatic node state detection through the server that continuously monitors signal data from all nodes. The server autonomously compares received signals with standard features and identifies failed nodes without human intervention, dramatically improving diagnosis efficiency while adding only moderate system complexity through the detection module.
Solution Approach 2:
The patent replaces the mechanical artificial maintenance process with an automated electronic detection system. The server uses signal data processing and comparison algorithms to substitute human diagnostic activities, improving productivity while maintaining relatively simple system architecture through standardized detection procedures.
3Ease of operation
If manual node diagnosis is performed, then system operation is simple, but timeliness and operability of failure detection worsen
Solution Approach 1:
The system implements continuous monitoring by having data acquisition terminals constantly receive signal data from nodes and transmit it to the server. The server continuously performs comparison operations with standard signal features, ensuring real-time detection of node failures without interrupting system operation, thus reducing detection time while maintaining operational simplicity.
Solution Approach 2:
The system performs preliminary action by pre-establishing standard signal feature information for each node before operation begins. When signal data is received, the server can immediately compare it against these pre-prepared standards, enabling rapid failure detection without requiring complex real-time analysis, thereby reducing detection time while keeping the system easy to operate.
