Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the terminal device uses a single communication service network, then the device complexity is low, but the service availability and reliability deteriorate when network failures or congestion occur
Solution Approach 1:
The patent segments the communication system into multiple independent communication service networks (first, second, and third networks). The terminal device can select from these segmented networks based on detection results, ensuring that failure in one segment does not affect overall service availability. This segmentation resolves the contradiction by providing redundancy without requiring a single complex unified system.
Solution Approach 2:
The patent changes the parameter of network selection by detecting connection statuses across multiple communication networks and dynamically selecting the optimal network based on detection results. This parameter change approach allows the system to adapt to varying network conditions, maintaining high reliability while managing complexity through standardized detection and selection procedures.
2Reliability
If the gateway device detects network connection status through multiple communication service systems, then the service availability improves, but the detection complexity and time consumption increase
Solution Approach 1:
The patent applies preliminary action by having the terminal device perform detection responses in advance to indicate its connection status to each communication service network before actual data transmission begins. The gateway device receives these preliminary detection results and selects the appropriate network accordingly, avoiding the need for complex real-time detection during data transmission.
Solution Approach 2:
The patent introduces an intermediary mechanism where the terminal device acts as a mediator between multiple communication networks and the gateway device. The terminal device detects and reports connection statuses to the gateway device, which then makes the network selection decision. This intermediary approach simplifies the overall detection complexity by centralizing the detection function at the terminal device rather than requiring the gateway device to directly detect all networks.
3Duration of action of stationary object
If the terminal device switches between multiple communication networks, then the service continuity is maintained, but the switching complexity and potential service interruption time increase
Solution Approach 1:
The patent applies preliminary action by performing network detection and selection before actual data transmission begins. The terminal device detects connection statuses and the gateway device selects the target network in advance, so that when data transmission starts, the optimal network path is already established. This minimizes switching time and maintains service continuity.
Solution Approach 2:
The patent implements feedback mechanisms where the terminal device continuously monitors and reports connection statuses to the gateway device. Based on this feedback, the gateway device can dynamically adjust network selection to maintain optimal service continuity. The feedback loop ensures that switching decisions are based on current network conditions, reducing unnecessary switching and associated time losses.
