Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users manually select controlled devices to provide services, then users can control specific devices, but user operation complexity increases and user experience decreases when moving between rooms
Solution Approach 1:
The controlled devices automatically detect terminal devices in proximity through signal strength detection and automatically provide services without requiring manual selection by users. The system performs self-service by autonomously determining which terminal should receive service based on detected signal strengths from multiple access points.
Solution Approach 2:
The system pre-determines service relationships by continuously monitoring signal strengths between terminal devices and controlled devices before user requests are made. This preliminary detection and determination of proximity relationships enables automatic service switching without manual intervention.
2Adaptability or versatility
If users re-select controlled devices when moving to new rooms, then services can continue in different locations, but operational complexity increases and user experience decreases
Solution Approach 1:
The system automatically detects when a terminal device moves to a new location by monitoring changes in signal strength patterns from multiple access points. The controlled devices self-adjust to provide continuous service to the moving terminal without requiring the user to manually re-select devices.
Solution Approach 2:
The system continuously monitors signal strength feedback from multiple access points to determine the relative positions of terminal devices and controlled devices. This real-time feedback enables automatic service switching when terminals move between rooms, maintaining service continuity adaptively.
3Measurement precision
If manual device selection is required, then users can precisely control which device provides service, but the system requires more user intervention and operations
Solution Approach 1:
The system replaces manual mechanical selection operations with automated electronic signal strength detection and processing. By using wireless signal strength measurements from multiple access points, the system automatically determines the closest terminal device and assigns service without requiring manual user input.
Solution Approach 2:
The system performs automatic device selection and service assignment through self-service mechanisms. Controlled devices autonomously detect terminal positions via signal strength monitoring and automatically determine which terminal should receive services, eliminating the need for manual user selection while maintaining precise device-terminal matching.
