Motor-Driven Parallelogram Stabilizer for Gravity-Axis Image Jitter
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional gimbals do not provide stabilization for photography devices against vibrations in the direction of gravity, leading to image jitter during image capture.
Innovation Solution
A load-stabilizing apparatus comprising a load-connecting member, a parallelogram mechanism, and a stabilizing motor that drives the parallelogram mechanism to deform, allowing the load-connecting member to move oppositely to vibrations, thereby compensating for gravity-induced vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional gimbal is used to stabilize the photographing device, then the device can compensate for vibrations in rotation directions (pitch, yaw, roll), but the device cannot compensate for vibrations in the direction of gravity
Solution Approach 1:
The patent extends the stabilization capability from three rotational axes to four dimensions by adding a parallel mechanism that provides translational movement along the gravity direction (Z-axis). This allows the system to compensate for both rotational vibrations and gravitational direction vibrations, achieving comprehensive six-degree-of-freedom stabilization.
2Reliability
If the stabilizing motor drives the parallelogram mechanism to deform to compensate for gravity-induced vibrations, then image jitter is reduced, but the structure becomes more complex
Solution Approach 1:
The patent combines the stabilizing motor with the parallelogram mechanism into an integrated assembly. The motor is positioned within the parallelogram structure and directly drives the connecting rods, merging the actuation system with the mechanical linkage to reduce overall system complexity while maintaining full stabilization functionality.
Solution Approach 2:
The parallelogram mechanism serves multiple functions: it provides translational movement along the gravity direction, maintains parallel orientation of the photographing device, and works cooperatively with the gimbal's rotational compensation. This multi-functionality reduces the need for separate mechanisms for each stabilization task.
