Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If connection gateways use different communication interfaces and protocols, then the network infrastructure becomes more versatile and adaptable, but the complexity of routing and environment discovery increases
Solution Approach 1:
The patent introduces a standardized message format as an intermediary layer between different communication interfaces and protocols. This message format acts as a universal language that translates diverse interface-specific protocols into a common structure, enabling gateways with different interfaces (Ethernet, WiFi, Bluetooth, etc.) to communicate without increasing routing complexity. The message format includes standardized fields for identification information and accessibility information, which simplifies the routing decision-making process.
Solution Approach 2:
The patent changes the parameter representation by using a unified message structure with standardized fields instead of interface-specific data formats. By transforming diverse protocol data into a common parameter structure (identification information, accessibility information, message payload), the system maintains adaptability across different interfaces while reducing routing complexity through consistent data handling.
2Measurement precision
If connection gateways regularly update routing information through environment discovery, then the routing accuracy and transmission optimization improve, but the time and energy consumption increase
Solution Approach 1:
The patent implements periodic environment discovery where connection gateways exchange standardized messages at regular intervals to update routing information. This periodic action ensures that routing information remains accurate and up-to-date without requiring continuous discovery processes. The standardized message format enables efficient information exchange during these periodic updates, reducing the time overhead compared to ad-hoc discovery methods.
Solution Approach 2:
The patent performs preliminary environment discovery and routing information gathering in advance, storing accessibility information about other gateways and connected objects before actual message transmission is needed. This preliminary action allows the gateway to have routing information ready when messages need to be sent, reducing the time required for real-time routing decisions while maintaining high accuracy through pre-collected data.
