Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If broadcast manner is used for data transmission in Bluetooth Mesh network, then one-to-many communication capability is achieved, but network load increases and device response slows down when the number of devices increases
Solution Approach 1:
The patent segments the Bluetooth Mesh network into multiple independent communication paths by introducing master node sets and device groups. Instead of single broadcast paths, data is transmitted through segmented routes from terminal devices to mesh network devices via specific master nodes, reducing network congestion and improving response speed while maintaining one-to-many communication capability.
2Productivity
If broadcast manner is used for data transmission, then data can reach multiple devices simultaneously, but the amount of transmitted data increases significantly with network size
Solution Approach 1:
The patent extracts and removes unnecessary broadcast data transmission by establishing direct communication paths. Only essential data needed for terminal device access is transmitted through the established master node routes, eliminating redundant broadcast messages and significantly reducing the total amount of transmitted data while maintaining efficient data access.
3Area of stationary object
If broadcast transmission is used, then network coverage can be extended to many devices, but network load becomes excessive affecting user online experience
Solution Approach 1:
The patent introduces dynamic path selection mechanisms where master node sets and device groups are adaptively configured based on network conditions and device locations. This dynamic approach allows the network to maintain extensive coverage while optimizing transmission paths to prevent excessive network load, thereby preserving user online experience across large networks.
