Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual labeling and fuse sheet updating are used, then implementation is simple, but human errors occur and labeling may detach due to environmental factors
Solution Approach 1:
The system enables automatic self-identification of power paths by having each power distribution unit automatically generate and transmit its identifier through the power line to downstream devices, eliminating the need for manual labeling and fuse sheet updates while ensuring continuous, accurate path tracking
Solution Approach 2:
The patent replaces manual mechanical labeling systems with an electronic data transmission system that uses power lines to carry identification signals, substituting physical labels and human operations with automated electronic identification and tracking
2Loss of information
If automated data signal transmission through power lines is implemented, then accurate and continuous power path identification is achieved, but system complexity and infrastructure requirements increase
Solution Approach 1:
The power line infrastructure serves dual purposes: delivering electrical power to devices and simultaneously transmitting identification data signals, eliminating the need for separate communication channels and reducing overall system complexity despite the automated identification capability
Solution Approach 2:
The power line acts as an intermediary that carries both power and data signals, enabling the transmission of path identifiers without requiring additional dedicated communication infrastructure, thus achieving accurate information transmission while minimizing added complexity

AI summary
Method and system are provided for power path identification in a power distribution system. The method transmits a data signal through a power line infrastructure including adding an identifier value at multiple points of the infrastructure to the data signal to form a concatenated path identifier formed of the identifier values. The method reads the path identifier at a reading point of the infrastructure to obtain power path information to or from the reading point in the power line infrastructure. A system may include a plurality of path identification devices each provided at a connection point of the power distribution system to transmit connection point identifiers to form a concatenated path identifier with identifier values of other connection points.
