Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If flooding mesh is employed to eliminate wiring requirements, then ease of installation is improved, but network congestion increases causing poor user experience
Solution Approach 1:
The system dynamically generates routing paths based on real-time node mappings discovered through credential exchanges. Rather than using static flooding, the routing paths are adaptively determined by the control circuitry based on the actual network topology and current conditions, allowing the system to maintain ease of wireless installation while optimizing network performance by avoiding redundant transmissions.
Solution Approach 2:
The system uses feedback from node credential exchanges and mappings to continuously optimize routing paths. The control circuitry receives information about node positions and credentials, processes this feedback to determine optimal routing paths, and updates the network accordingly, thereby reducing congestion while maintaining the wireless mesh structure.
2Reliability
If manual configuring is used to manage node placement, then network control is improved, but device complexity and time consumption increase
Solution Approach 1:
The system enables nodes to automatically discover and map their positions in the network through credential exchanges with neighboring nodes. Each node independently contributes to building the overall network map by sharing its credentials and receiving credentials from neighbors, eliminating the need for manual configuration while maintaining reliable network control through the automatically generated node mappings.
Solution Approach 2:
The control circuitry performs preliminary actions by initiating credential exchange processes and automatically generating node mappings before routing is required. This preliminary discovery phase establishes the network topology in advance, so that when data transmission is needed, optimized routing paths are already available without requiring manual intervention.
3Productivity
If prior knowledge of node placement is required for configuration, then routing optimization is improved, but adaptability to different installations deteriorates
Solution Approach 1:
The system dynamically discovers node placements and generates routing paths based on actual network conditions rather than relying on pre-configured placement knowledge. The control circuitry adapts to different installation geometries by processing credential exchanges from whatever node configuration exists, automatically generating appropriate node mappings and routing paths that are optimized for the specific installation without requiring prior knowledge.
