Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing fans are used, then the device structure is simple, but the airflow direction cannot be dynamically adjusted to track user location
Solution Approach 1:
The patent applies the Dynamics principle by implementing a movable fan head assembly that can dynamically adjust its orientation in real-time. The fan head is mounted on a rotating mechanism with adjustable altitude and azimuth angles, allowing it to track and follow the user's movement throughout the room, transforming a static fan into a dynamic tracking system.
Solution Approach 2:
The patent implements the Feedback principle through a closed-loop control system. Sensors detect the user's position and movement, this information is fed back to the control circuit, which then adjusts the fan head's orientation accordingly. This continuous feedback loop enables the fan to automatically track and maintain airflow directed at the user.
2Measurement precision
If a tracking system with GPS coordinates is implemented, then user location tracking precision is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical tracking systems with electronic sensing and wireless communication technology. Instead of using mechanical sensors and complex linkages to detect user position, the system uses personal data devices with GPS or wireless communication capabilities to electronically determine location, significantly simplifying the mechanical structure while maintaining high precision.
Solution Approach 2:
The patent introduces a personal data device as an intermediary between the user and the fan system. This intermediary device carries the user's location information and communicates it wirelessly to the fan's control circuit, eliminating the need for complex direct sensing mechanisms on the fan itself and reducing overall system complexity.
3Manufacturing precision
If wireless communication link with personal data device is established, then airflow direction control accuracy is improved, but energy consumption increases
Solution Approach 1:
The patent implements periodic action by having the wireless communication system transmit location data at intervals rather than continuously. The personal data device and fan control circuit exchange position information periodically, which maintains accurate tracking while significantly reducing energy consumption compared to continuous real-time communication.
