Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If external RFID tags are attached to cable exteriors for temperature measurement, then temperature data can be read by external reader devices, but the tags are costly, prone to detachment, and cannot accurately measure internal cable temperatures
Solution Approach 1:
The RFID tag is implanted inside the cable structure, with the antenna and reflector nested between the armor layer and outer sheath. This nested configuration ensures the tag remains securely attached while enabling direct measurement of internal cable temperatures, resolving both the attachment reliability and measurement accuracy issues
Solution Approach 2:
The patent introduces an intermediary manufacturing module that implants the RFID tag during cable production. This intermediary process integrates the tag into the cable structure itself, making detachment impossible while maintaining measurement capability through the cable layers
2Loss of information
If on-site coding of RFID tags is performed for distribution cables, then asset identification can be achieved, but significant human and material resources are consumed
Solution Approach 1:
The RFID tag encoding is performed in advance during cable manufacturing, before the cable is deployed to the field. This preliminary action eliminates the need for time-consuming on-site coding operations, as tags are pre-programmed with asset identification information during production
Solution Approach 2:
The patent combines the RFID tag implantation and encoding process with the cable manufacturing process itself. The manufacturing module performs both tag insertion and data programming in a single integrated operation, eliminating separate coding steps and reducing resource consumption
3Productivity
If manual reading of remaining meter markings is used for cable inventory management, then inventory tracking can be performed, but the process is highly susceptible to errors and has low efficiency
Solution Approach 1:
The patent replaces manual visual inspection of meter markings with automated RFID reading systems. The RFID tags store precise cable identification and inventory information that can be rapidly read electronically, eliminating human error and significantly improving inventory management efficiency and accuracy
4Loss of information
If externally attached RFID tags are used for cable identification, then basic traceability can be achieved, but the tags cannot support full lifecycle management and are susceptible to environmental damage
Solution Approach 1:
The RFID tag is nested within the cable structure between the armor layer and outer sheath, protecting it from environmental factors such as moisture, UV radiation, and physical damage. This protected positioning ensures long-term reliability for full lifecycle management while maintaining complete traceability information
Solution Approach 2:
The patent introduces an intermediary manufacturing module that integrates the RFID tag into the cable structure during production. This intermediary process ensures the tag is permanently embedded and protected from environmental damage throughout the cable's entire lifecycle, enabling comprehensive traceability
