Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple WiFi access points are installed to expand coverage area, then coverage area is improved, but device complexity and maintenance difficulty increase
Solution Approach 1:
The system segments the coverage area into multiple zones, each served by a separate WiFi access point connected to different ports of the mobile communication relay device. This allows independent configuration and management of each segment while achieving overall area coverage.
Solution Approach 2:
The mobile communication relay device performs multiple functions: it acts as a signal amplifier for mobile communication and simultaneously serves as a signal distribution hub for multiple WiFi access points. This multi-functionality reduces the need for separate dedicated equipment for each purpose.
2Productivity
If multiple WiFi access points operate simultaneously on common frequency, then data transmission capability is improved, but signal interference and hidden node problems occur
Solution Approach 1:
Each WiFi access point is assigned to serve a specific local area or zone with distinct signal characteristics. The system configures each access point with appropriate transmission parameters suited to its local environment, reducing interference with other access points while maintaining high data transmission capability within each zone.
3Speed
If WiFi uses common frequency band for high-speed transmission, then data transmission speed is improved, but frequency interference with other services occurs
Solution Approach 1:
The system dynamically adjusts transmission parameters of WiFi access points based on detected interference levels from other communication services. When interference is detected, the system modifies frequency usage or transmission power to maintain high-speed data transmission while minimizing harmful effects on other services.
