Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If wireless transmission is used to resolve deployment difficulties and high construction costs, then ease of deployment and cost are improved, but signal strength and transmission stability deteriorate when transmitting over long distances or through obstructions
Solution Approach 1:
The system segments the wireless transmission task by dividing packets into different queues based on destination MAC addresses and packet types. Each queue is associated with specific transmission parameters, allowing optimized handling of different data flows to maintain stability while preserving deployment flexibility
Solution Approach 2:
The system dynamically adjusts transmission parameters including queue scheduling priorities and antenna selection based on real-time network conditions, destination addresses, and packet types. This dynamic adaptation maintains transmission stability without requiring complex physical infrastructure
2Reliability
If signal strength is increased to ensure successful transmission over long distances, then transmission reliability is improved, but energy consumption and interference increase
Solution Approach 1:
The system changes transmission parameters dynamically based on packet characteristics and destination. By adjusting queue scheduling priorities and selecting appropriate wireless antennas based on MAC address mappings, the system optimizes energy usage while maintaining transmission success rates without consistently using maximum power
3Reliability
If multiple queues and mapping relationships are implemented to improve packet transmission reliability, then transmission stability is improved, but device complexity increases
Solution Approach 1:
The system uses universal mapping relationships between MAC addresses, packet types, and queues that can handle multiple scenarios through a unified framework. The same queue scheduling mechanism and antenna selection process work for different destination devices and packet types, reducing complexity through standardization
Solution Approach 2:
The system automatically determines target queues and wireless antennas based on preset mapping relationships without requiring manual configuration for each transmission. The self-service nature of the mapping lookup and queue selection reduces operational complexity while maintaining transmission stability
