Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If users manually determine and configure direct communication functions and frequency bands, then communication settings can be customized, but operation complexity increases and ease of operation deteriorates
Solution Approach 1:
The communication apparatus automatically determines and activates appropriate direct communication functions and frequency bands based on its own capabilities and current communication state, without requiring user configuration. The control unit performs automatic determination of whether to activate first or second direct communication functions, and selects frequency bands autonomously, making the system self-configuring.
Solution Approach 2:
The system dynamically changes communication parameters including frequency band selection (2.4 GHz, 5 GHz, 6 GHz bands), direct communication function activation state, and operational mode based on detected communication environment and device capabilities, allowing adaptive optimization without user intervention.
2Adaptability or versatility
If multiple direct communication functions are activated simultaneously, then communication versatility improves, but device complexity increases
Solution Approach 1:
The system dynamically activates or deactivates direct communication functions based on real-time communication requirements and environmental conditions. The control unit determines whether to activate first or second direct communication functions by evaluating communication state, enabling the system to adapt its functional complexity rather than maintaining fixed high complexity.
Solution Approach 2:
The communication apparatus is designed with multiple direct communication functions that can be selectively activated. The system provides universal communication capability across different frequency bands and communication modes, activating only the necessary functions for current needs, thus maintaining versatility while managing complexity.
3Ease of operation
If automatic determination of direct communication functions is implemented, then ease of operation improves, but loss of information about user preferences increases
Solution Approach 1:
The control unit continuously monitors communication state, connection status, and operational performance to dynamically adjust direct communication function activation. This feedback mechanism allows the system to learn from actual communication outcomes and adapt to user needs implicitly, compensating for the lack of explicit user preference input.
