Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If manual operation method is used to fold and unfold the screen, then the structure is simple, but the operation is complicated and inefficient
Solution Approach 1:
The hinge mechanism automatically adjusts the screen angle by detecting the current angle through the angle detecting unit and driving the rotation axle via the motor unit to rotate the screen to the predetermined angle, enabling the system to serve itself without manual intervention
Solution Approach 2:
The patent replaces the purely manual mechanical operation with an automated system combining mechanical components (rotation axle, connecting components) and electronic control (angle detecting unit, motor unit, controller) to achieve automatic screen angle adjustment
2Ease of operation
If automatic angle rotation is implemented, then the operation is simplified, but the device complexity increases
Solution Approach 1:
The hinge mechanism automatically detects the current screen angle through the angle detecting unit and drives the rotation axle via the motor unit to rotate the screen to the predetermined angle, enabling the system to serve itself without manual intervention
Solution Approach 2:
The angle detecting unit continuously monitors the rotation angle of the rotation axle and provides feedback to the controller, which compares the detected angle with the predetermined angle and adjusts the motor unit's driving action accordingly to achieve precise positioning

AI summary
An electronic device has a method capable of automatically executing angle rotation. A second body is rotatably connected to a first body of the electronic device. A hinge mechanism is disposed between the first body and the second body. The hinge mechanism includes a hinge component, a motor unit, a coupling component and an angle detecting unit. The first body and the second body are connected to the hinge component. The motor unit is electrically connected to a controller of the electronic device. The coupling component is connected between the hinge component and the motor unit. The angle detecting unit is connected to the hinge component or the coupling component to read its rotary angle. The controller drives the motor unit to rotate the hinge component via the coupling component, and the second body can be moved relative to the first body and be fixed at a predetermined position.
