Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-link aggregation router uses built-in cellular communication modules for multiple network standards, then it can meet diverse networking requirements, but the device complexity and cost increase significantly
Solution Approach 1:
The patent extracts the cellular communication modules from the router body and makes them independent detachable components. The router only retains communication interfaces that can connect to external modules, thereby reducing the router's internal complexity while maintaining the ability to support multiple network standards through external module attachment.
Solution Approach 2:
The patent designs a universal communication interface on the router that can accommodate different types of external cellular communication modules. This universal interface allows a single router model to work with multiple network standards by simply changing the external module, achieving multi-functionality without increasing the router's inherent complexity.
2Adaptability or versatility
If a multi-link aggregation router supports multiple network standards with built-in modules, then it can meet diverse customer needs, but the manufacturing cost and device price increase
Solution Approach 1:
The patent segments the cellular communication functionality into separate independent modules that can be manufactured independently of the router. This allows the router to be produced as a standardized base unit, while different cellular modules can be manufactured separately and attached as needed, reducing overall manufacturing complexity and cost.
Solution Approach 2:
The patent treats external cellular communication modules as replaceable, potentially lower-cost components that can be easily attached or detached. This approach allows customers to choose affordable modules for specific needs rather than paying for a high-end router with all possible network standards built-in, effectively reducing the base router's manufacturing cost.
3Ease of manufacture
If a router model is designed for a specific network standard, then the manufacturing cost is reduced, but it cannot meet diverse networking requirements of different customers
Solution Approach 1:
The patent makes the router's network standard support dynamic rather than static. The router can adapt to different network standards by accepting different external cellular communication modules, allowing the functionality to change based on customer needs while the base router remains a standardized, cost-effective product.
4Adaptability or versatility
If external cellular communication devices are detachably connected to communication interfaces, then the device can meet various networking requirements, but the reliability of connection may be affected
Solution Approach 1:
The patent incorporates detection mechanisms that check the connection status of external cellular communication modules before establishing network connections. This allows the system to identify and handle potential connection issues in advance, ensuring reliable network operation by validating module presence and status before use.
