Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a user carries a charger and a network interface conversion device separately, then both charging and network conversion functions are available, but the user needs to carry multiple peripherals and frequently plug in or remove them
Solution Approach 1:
The patent combines the charger and network interface conversion device into a single integrated charger that provides both charging functionality and network interface conversion capabilities. The charger includes a charging circuit for power conversion and a network interface adapter circuit for data format conversion between optical fiber access networks and wireless mobile gateway devices, eliminating the need to carry and switch between separate devices
Solution Approach 2:
The integrated charger serves multiple functions simultaneously: it converts AC power to DC for charging the wireless mobile gateway device, performs network interface conversion between different data formats, and enables network access. This multi-functional design allows a single device to replace what previously required multiple separate peripherals
2Adaptability or versatility
If an access routing device supports both optical fiber access network and wireless wide area network, then network access flexibility is improved, but the device size becomes too large for portability
Solution Approach 1:
The patent divides the network access functionality into two segments: a fixed access routing device that handles network routing, and a portable integrated charger that provides network interface conversion and charging. This segmentation allows the wireless mobile gateway device to access networks through either optical fiber or wireless wide area network by connecting to different interfaces of the integrated charger, maintaining network access flexibility while ensuring portability
3Weight of moving object
If a wireless mobile gateway device is used without integrated charging, then device mobility is maintained, but usage time is limited by battery capacity
Solution Approach 1:
The integrated charger enables preliminary charging action by converting AC power to DC and storing energy in the wireless mobile gateway device's battery before actual use. The charging circuit is pre-configured to provide power conversion, ensuring that the device is charged in advance, thereby extending usage time without compromising mobility
