Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If traditional reconfiguration methods are used for PMR network infrastructure, then system reliability is maintained, but reconfiguration speed and ease of operation deteriorate
Solution Approach 1:
The patent introduces an external storage device as an intermediary carrier to transfer the supplementary list of mobile terminal identifiers. This mediator enables rapid reconfiguration by allowing operators to simply connect the device to a port (e.g., USB port) and automatically import the list, eliminating complex manual configuration procedures and significantly reducing reconfiguration time while maintaining system reliability through controlled list merging or replacement mechanisms.
2Adaptability or versatility
If manual reconfiguration methods are used, then system complexity remains low, but adaptability to changing user needs deteriorates
Solution Approach 1:
The patent implements preliminary action by pre-preparing a supplementary list of mobile terminal identifiers on an external storage device before reconfiguration is needed. This allows the system to rapidly adapt to changing user needs by simply connecting the pre-prepared list to the network infrastructure, enabling quick deployment of new users or groups without complex real-time configuration processes.
Solution Approach 2:
The system automatically detects the connection of the external storage device and performs self-service by automatically importing and merging or replacing the list of mobile terminal identifiers without requiring complex manual intervention. This self-service mechanism enhances adaptability while keeping the operational complexity low for end users.
3Productivity
If automated detection of external storage device is implemented, then productivity of reconfiguration process is improved, but device complexity increases
Solution Approach 1:
The patent implements automated feedback mechanisms where the network infrastructure continuously monitors for the connection and disconnection of external storage devices. When detected, the system automatically triggers the import process for the supplementary list, and when disconnected, automatically applies the reconfigured list. This feedback-driven automation significantly improves reconfiguration productivity by eliminating manual steps while managing complexity through standardized detection protocols at the port level.
