Adjustable Gimbal Frame for Load Balance and Shaft Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current gimbals experience unexpected torque and wear due to changes in the center of gravity when carrying different loads, affecting the lifetime and precision of motor-driven rotation shafts.
Innovation Solution
A gimbal design featuring a first and second frame with movable segments and locking parts, allowing for extension or retraction to adjust the load's position relative to the gimbal, thereby stabilizing the center of gravity and reducing torque on rotation shafts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the gimbal carries different loads, then the gimbal can accommodate various imaging devices, but the center of gravity changes causing unexpected torque and extra wear on the motor
Solution Approach 1:
The patent applies the dynamics principle by making the frame structure adjustable through movable segments that can change position. The frame includes connecting segments and movable segments that can extend or retract relative to each other, allowing the center of gravity to be dynamically adjusted to match different load configurations, thereby preventing unexpected torque and motor wear
2Adaptability or versatility
If the gimbal carries different loads, then the gimbal can handle various weights, but the center of gravity changes affecting precision of gimbal control
Solution Approach 1:
The movable segments allow the frame to dynamically adjust its configuration based on load requirements. By extending or retracting the movable segments relative to the connecting segments, the center of gravity position can be optimized for different load weights, maintaining gimbal control precision across various operating conditions
3Strength
If the frame is made rigid for stability, then the gimbal structure is strong, but it cannot adjust to different loads and centers of gravity
Solution Approach 1:
The frame is segmented into connecting segments and movable segments that can move relative to each other. This segmentation allows the frame to maintain structural strength through its rigid segments while enabling adjustment capability through the movable segments, resolving the contradiction between strength and adaptability
Solution Approach 2:
The frame transitions from a static rigid structure to a dynamic adjustable structure. The movable segments can extend or retract to change the frame's configuration, allowing the gimbal to adapt to different loads while maintaining structural integrity through the connecting segments

AI summary
A gimbal for carrying a load includes a first frame configured to be coupled with the load, and a second frame rotatably coupled with the first frame. At least one of the first frame or the second frame includes a connecting segment and a movable segment movably coupled with the connecting segment. The movable segment is movable relative to the connecting segment to cause the at least one of the first frame or the second frame to extend or retract. The at least one of the first frame or the second frame includes a locking part disposed on one of the connecting segment and the movable segment. The locking part is configured to abut against the connecting segment or disengage from the connecting segment for placing the movable segment in a locked state or a movable state.
