Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple kitchen appliances are directly connected to the router via Wi-Fi, then each appliance can access the Internet independently, but the routing pressure increases and control becomes cumbersome
Solution Approach 1:
The patent introduces a gateway device as an intermediary between kitchen appliances and the router. The gateway establishes a Bluetooth Low Energy (BLE) mesh network to connect multiple appliances, reducing the number of direct Wi-Fi connections to the router from many to one, thereby significantly reducing routing pressure while maintaining network stability
Solution Approach 2:
The patent segments the network into two parts: a BLE mesh network for appliance-to-gateway communication and a Wi-Fi connection for gateway-to-Internet communication. This segmentation allows local device communication to occur independently without burdening the central router, resolving the contradiction between network stability and routing load
2Adaptability or versatility
If sensor networks such as BLE and ZIGBEE are converted into Wi-Fi networks through protocol conversion, then all devices can use a unified protocol, but the conversion process is complex and no effective solution exists in the industry
Solution Approach 1:
The gateway device serves as a protocol mediation intermediary that receives data from various sensor networks (BLE, ZIGBEE) and forwards them to the Wi-Fi network without requiring direct protocol conversion. This approach maintains protocol compatibility while avoiding the complexity of protocol conversion processes
Solution Approach 2:
The gateway device is designed with multi-functionality to support multiple communication protocols (BLE, ZIGBEE, Wi-Fi) simultaneously. This universal design allows the system to accommodate different sensor networks without requiring complex conversion mechanisms, as the gateway can natively handle multiple protocols
