Engineering Contradictions & Design Principles

VSEngineering 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

Engineering Contradiction:
Improvereconfiguration easeVSAvoidreconfiguration time
Core Design Contradiction:
Ease of operationVSLoss of time

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.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Adaptability or versatility

If manual reconfiguration methods are used, then system complexity remains low, but adaptability to changing user needs deteriorates

Engineering Contradiction:
Improveadaptability to user needsVSAvoidreconfiguration system complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

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.

Inventive Principle:
Principle #10Preliminary action

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.

Inventive Principle:
Principle #25Self-service

3Productivity

If automated detection of external storage device is implemented, then productivity of reconfiguration process is improved, but device complexity increases

Engineering Contradiction:
Improvereconfiguration efficiencyVSAvoiddetection and processing complexity
Core Design Contradiction:
ProductivityVSDevice complexity

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.

Inventive Principle:
Principle #23Feedback
