Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The user experience of gimbals is hindered by cumbersome power-on and power-off operations, particularly in foldable or deformable structures, and contact sensors often result in mechanical loss and reduced sensing range.
Innovation Solution
A gimbal design incorporating non-contact sensors, such as magnetic induction, infrared, or ultrasonic sensors, to automatically control power-on and power-off operations based on the relative position of assemblies, allowing for convenient power management through positional changes without mechanical contact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact sensors are used to detect assembly position for power control, then the sensing function is achieved, but mechanical loss increases and service life decreases
Solution Approach 1:
The patent replaces contact sensors with non-contact sensors (such as magnetic sensors, capacitive sensors, or optical sensors) to detect the relative position between assemblies. This substitution eliminates mechanical contact, thereby reducing mechanical loss and wear while maintaining the sensing function, which directly improves service life and reduces energy loss.
2Measurement precision
If contact sensors are used to detect assembly position, then power control is enabled, but sensing range is reduced
Solution Approach 1:
By substituting contact sensors with non-contact sensors, the system achieves a larger sensing range since non-contact sensors can detect position changes over greater distances without physical contact. This maintains ease of operation for power control while expanding the operational envelope of the gimbal system.
3Ease of operation
If manual power-on/power-off operations are required, then power management is achieved, but user convenience is reduced
Solution Approach 1:
The patent implements automatic power control by having the system self-detect the relative position between assemblies through non-contact sensors and automatically execute power-on or power-off operations based on detected states. This eliminates the need for manual user intervention, thereby improving user convenience while increasing the extent of automation.
Solution Approach 2:
The system uses non-contact sensors to continuously monitor the relative position between assemblies and provides feedback to the control unit, which then automatically adjusts power states based on the feedback signal. This closed-loop feedback mechanism enables convenient automatic power management without requiring manual operations.

AI summary
A gimbal includes a first assembly, a second assembly mechanically coupled to the first assembly, one or more non-contact sensors arranged at the first assembly and/or the second assembly and configured to output a sensing signal, and one or more processors. The first assembly includes a member configured to rotate relative to the second assembly with a first degree of freedom and a second degree of freedom. The first degree of freedom corresponds to a preset rotation range. The one or more processors are configured to control the gimbal to perform a control operation according to the sensing signal in response to the member rotating, with the second degree of freedom, relative to the second assembly at any angle within the rotation range. The control operation includes a power-on operation or a power-off operation.
