Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple communication modules are installed to provide both narrow-range and wide-range communication capabilities, then communication versatility is improved, but device complexity and control difficulty increase
Solution Approach 1:
The patent combines multiple communication modules (narrow-range Wi-Fi module and wide-range mobile communication module) into a single integrated wireless communication device housing. This merging approach maintains communication versatility while simplifying the overall system structure and reducing control complexity by providing unified management of all communication functions through a single device rather than separate independent modules.
Solution Approach 2:
The wireless communication device is designed as a universal platform that performs multiple communication functions through integrated modules. The device can selectively activate either narrow-range Wi-Fi communication or wide-range mobile communication based on network availability and requirements, providing multi-functionality within a single device structure that simplifies control while maintaining versatility.
2Adaptability or versatility
If multiple communication modules are installed to provide both narrow-range and wide-range communication capabilities, then communication versatility is improved, but mount space requirements increase
Solution Approach 1:
The patent merges the narrow-range Wi-Fi communication module and wide-range mobile communication module into a single integrated housing unit. This combination significantly reduces the total mount space required compared to installing separate independent modules, while still providing both communication capabilities through the unified device structure.
Solution Approach 2:
The communication modules are nested within a single housing structure, with the Wi-Fi module and mobile communication module contained within the same physical enclosure. This nesting arrangement optimizes space utilization by allowing compact integration of multiple communication functions in a reduced volume suitable for vehicle installation.
3Adaptability or versatility
If communication modules operate without priority control, then communication flexibility is improved, but data transmission reliability deteriorates due to potential data falsification risks
Solution Approach 1:
The controller is pre-programmed with priority control logic that automatically determines which communication module should be used based on predefined criteria such as network availability, data type, and communication requirements. This preliminary action of establishing control rules in advance ensures reliable data transmission by preventing unauthorized or falsified data from being transmitted through inappropriate channels, while still maintaining communication flexibility when conditions change.

AI summary
In an in-vehicle router, a narrow-range communication module (10A) is a device capable of wireless communication. A wide-range communication module is a device capable of wireless communication in the wider range than the narrow-range communication module. An Ethernet module is connected to an in-vehicle LAN in a vehicle so that communication is possible. A CPU controls the narrow-range communication module and the wide-range communication module and communicates with the in-vehicle LAN through the Ethernet module. The narrow-range communication module, the wide-range communication module, the Ethernet module, and the CPU are assembled to a housing, and the housing is provided to the vehicle.
