Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple wireless direct function methods are provided, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent implements dynamic switching between different wireless direct function methods (WFD and SoftAP) based on the selected frequency band. The control unit automatically adjusts the communication method according to whether 5 GHz or 6 GHz band is chosen, making the system adaptable without requiring complex manual configuration by users.
Solution Approach 2:
The patent changes the operational parameters of the wireless direct function based on frequency band selection. When 5 GHz is selected, WFD method is activated; when 6 GHz is selected, SoftAP method is activated. This parameter-based switching resolves the contradiction by automating the adaptation process.
2Ease of operation
If automatic frequency band selection is implemented, then ease of operation is improved, but loss of information increases
Solution Approach 1:
The patent incorporates feedback mechanisms where the control unit receives frequency band settings from the reception unit and automatically selects the appropriate wireless direct function method. This closed-loop control ensures that the system maintains communication reliability by matching the correct protocol to the selected frequency band without requiring user expertise.
Solution Approach 2:
The system performs self-configuration by automatically selecting the appropriate communication method based on the frequency band setting. The control unit autonomously determines whether to use WFD or SoftAP without user intervention, improving ease of operation while maintaining reliability through intelligent decision-making.
