Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If resources of the terminal device are shared among multiple SIM cards, then resource utilization is improved, but resource allocation control becomes unclear
Solution Approach 1:
The patent implements dynamic resource allocation by enabling the terminal device to negotiate capabilities with the network device through capability negotiation messages. The resource allocation is not fixed but dynamically adjusted based on service requirements and network conditions, allowing flexible sharing among multiple SIM cards while maintaining clear control mechanisms.
Solution Approach 2:
The patent changes the parameter of resource allocation from static to dynamic by introducing capability negotiation between terminal and network devices. Through message exchange, the terminal device can indicate its resource sharing capabilities and the network device can allocate resources accordingly, transforming the rigid resource management into a flexible parameter-based control system.
2Adaptability or versatility
If capability negotiation messages are introduced for resource control, then resource flexibility is improved, but communication overhead increases
Solution Approach 1:
The capability negotiation messages serve multiple functions: they indicate resource sharing capabilities, establish allocation parameters, and enable flexible resource control. By making these messages multi-functional, the patent reduces the need for separate signaling mechanisms, thereby limiting communication overhead while achieving resource flexibility.
3Adaptability or versatility
If multiple SIM cards share terminal device resources, then service coverage is improved, but service interruption risk increases
Solution Approach 1:
The patent applies preliminary action by having the terminal device proactively negotiate its capabilities with the network device before service interruptions occur. Through capability negotiation messages, the terminal device pre-establishes resource allocation arrangements, ensuring that services can continue without interruption even when multiple SIM cards share resources.
