Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If engineers manually set wiring between communication devices in central offices, then wiring can be configured, but human errors occur and on-site visits are required
Solution Approach 1:
The patent uses image processing to capture photographs of physical wiring connections and creates digital copies of the wiring information. The system automatically extracts connection details from images of communication devices and physical ports, generating wiring information without requiring manual input from engineers, thereby eliminating human errors while maintaining operational ease
Solution Approach 2:
The patent replaces the mechanical process of manual wiring configuration with an automated image-based system. Instead of engineers physically connecting and recording wiring information, the system uses cameras to capture images of the physical connections and automatically processes these images to extract wiring information, substituting mechanical manual operations with automated optical and computational processes
2Ease of repair
If engineers visit sites to address breakdowns or perform updates, then maintenance can be performed, but costs increase and communication is disconnected
Solution Approach 1:
The patent enables the communication system to self-diagnose and self-report its state by automatically capturing images of wiring connections and generating wiring information without human intervention. The system monitors its own physical connections and provides maintenance information autonomously, reducing the need for engineer visits and minimizing communication disruption during maintenance operations
Solution Approach 2:
The patent captures images of wiring connections and generates wiring information in advance before breakdowns occur. By continuously monitoring and documenting the physical wiring state through automated image capture, the system prepares maintenance information ahead of time, enabling rapid response when issues arise without requiring immediate on-site engineer visits
3Reliability
If redundancy is designed in access sections, then reliability improves, but costs increase due to large number of communication ports and devices
Solution Approach 1:
The patent creates digital copies of physical wiring information through image processing, eliminating the need for manual documentation of each communication port and device connection. This digital copying approach simplifies the management of redundant configurations by automatically capturing and storing wiring information, reducing the operational complexity associated with managing numerous communication ports while maintaining reliability
