Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice control is used for smart home devices, then control convenience is improved, but it becomes inconvenient for users who prefer not to speak
Solution Approach 1:
The control system is designed to support multiple control modes including voice control, gesture control, and other non-voice control methods. This multi-functionality allows the system to adapt to different user preferences and scenarios, resolving the contradiction between voice control convenience and user preference adaptability
2Measurement precision
If radar wave monitoring is continuously performed, then action recognition accuracy is improved, but energy consumption increases
Solution Approach 1:
The radar wave monitoring is performed periodically rather than continuously. The system monitors user actions at regular intervals and only processes data when changes are detected, which maintains action recognition accuracy while significantly reducing energy consumption compared to continuous monitoring
3Adaptability or versatility
If multiple control modes are supported, then user preference adaptability is improved, but device complexity increases
Solution Approach 1:
A control unit serves as an intermediary that manages multiple control modes. This centralized control unit receives inputs from various sensors (voice sensors, radar wave sensors, gesture sensors), processes them uniformly, and executes appropriate commands, thereby supporting multiple control modes while managing system complexity through a unified architecture
