Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If millimeter wave antennas are used for 5G communication, then communication speed is improved, but signal strength deteriorates due to object occlusion
Solution Approach 1:
The patent applies the dynamics principle by making the antenna rotatable rather than fixed. The antenna can dynamically adjust its orientation to point towards the base station, allowing it to adapt to different occlusion scenarios and maintain optimal signal reception while preserving the high-speed 5G communication capability
Solution Approach 2:
The patent implements feedback through a position detection mechanism that monitors the antenna's rotational position and provides information to a control system. This feedback loop enables the system to automatically adjust the antenna orientation based on detected signal conditions, resolving the contradiction between maintaining high speed and ensuring reliable signal reception
2Reliability
If the antenna is made rotatable to avoid occlusion, then signal strength is improved, but device complexity increases
Solution Approach 1:
The patent replaces complex mechanical positioning systems with a simplified rotational mechanism driven by a small motor. The position detection uses magnetic sensors rather than complex mechanical encoders, significantly reducing device complexity while still enabling the antenna to rotate and maintain optimal signal strength
Solution Approach 2:
The patent changes the control parameter from complex spatial positioning to simple rotational angle measurement. By using Hall sensors or magnetic elements to detect rotational position, the system achieves accurate antenna orientation with minimal complexity, improving signal strength without significantly increasing device complexity

AI summary
The present application provides a network device. The network device comprises a base, a holder, a functional device, a position detector, and a master controller. The holder is rotatably connected to the base. The functional device is born on the holder, and rotates with the rotation of the holder. The position detector comprises a Hall sensor and a magnetic member. One of the Hall sensor and the magnetic member is fixed on the base, and the other is fixed on the holder and rotates with the rotation of the holder. The distance between the Hall sensor and the magnetic member keeps unchanged in the direction perpendicular to a plane of rotation where the holder rotates. The Hall sensor is located within the range of the magnetic field of the magnetic member. When rotating relative to the magnetic member, the Hall sensor senses the change in the magnetic field of the magnetic member and outputs a detection signal. The master controller determines the position of the functional device relative to the base according to the detection signal. According to the present application, the detection accuracy of detecting the position of the functional device relative to the base by the Hall sensor is high.
