Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If multiple WiFi access points are installed to increase coverage area, then coverage area is improved, but device complexity and management difficulty increase
Solution Approach 1:
The patent combines multiple WiFi access points into a single integrated apparatus that can simultaneously transmit multiple WiFi signals through different communication relays. This merging approach achieves wide coverage area while maintaining simple management as a single device rather than multiple separate access points.
Solution Approach 2:
The WiFi access point apparatus is designed with multi-functionality to perform both WiFi signal transmission and mobile communication relay functions simultaneously. This universal design allows one device to replace multiple specialized devices, reducing management complexity while maintaining comprehensive coverage.
2Productivity
If multiple WiFi access points are installed to serve increasing smartphone users, then service capacity is improved, but installation and maintenance cost increase
Solution Approach 1:
The patent merges multiple access point functions into a single apparatus that serves multiple smartphone users simultaneously through integrated WiFi and mobile communication relay capabilities. This reduces the number of physical installations required while maintaining high service capacity.
Solution Approach 2:
The apparatus acts as an intermediary between WiFi networks and mobile communication relays, enabling cost-effective expansion of service capacity by utilizing existing mobile communication infrastructure rather than requiring separate WiFi installations for each user.
3Speed
If WiFi systems operate in ISM band for high-speed data transmission, then data transmission speed is improved, but frequency interference increases
Solution Approach 1:
The patent introduces mobile communication relay as an intermediary layer between WiFi transmission and the wireless medium. This allows WiFi to operate in the ISM band for high-speed data transmission while the relay system manages and mitigates frequency interference through coordinated communication.
Solution Approach 2:
The system dynamically adjusts transmission parameters including frequency selection and power levels based on interference conditions. This allows maintaining high data transmission speed in the ISM band while adapting to minimize frequency interference with other communication services.
