Parallelogram Load Stabilizer for Vertical Vibration Compensation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing photographing devices face challenges in achieving stable images due to vibrations, as conventional gimbals only provide stabilization in rotational directions and not in the direction of gravity.
Innovation Solution
A load-stabilizing apparatus is introduced, comprising a load-connecting member, a parallelogram mechanism, and a stabilizing motor. The stabilizing motor drives the parallelogram mechanism to deform, allowing the load-connecting member to move and compensate for vibrations in the vertical direction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a conventional gimbal is used to stabilize the photographing device, then rotational vibration compensation is improved, but vertical direction stabilization is not achieved
Solution Approach 1:
The stabilization system is divided into two independent parts: a conventional gimbal for rotational compensation and a new vertical driving mechanism for gravity direction compensation. This segmentation allows each component to specialize in its specific function without interfering with the other, thereby achieving comprehensive stabilization coverage.
Solution Approach 2:
The patent adds a new dimension of stabilization by introducing vertical movement capability along the gravity direction, complementing the traditional rotational compensation. This transforms the stabilization from two-dimensional (rotational axes) to three-dimensional (including vertical translation), fully addressing the image stability requirement.
2Reliability
If a gimbal is used for vibration compensation, then rotational axis stability is improved, but the device complexity increases due to lack of vertical stabilization
Solution Approach 1:
The patent merges the conventional gimbal mechanism with a vertical driving mechanism into an integrated load-stabilizing apparatus. The gimbal handles rotational compensation while the vertical mechanism (comprising a parallelogram mechanism and driving component) handles gravity-direction compensation, creating a unified system that achieves comprehensive stabilization without requiring separate independent systems.
Solution Approach 2:
The load-stabilizing apparatus is designed to perform multiple functions: rotational compensation through the gimbal and vertical compensation through the driving mechanism. This multi-functional design eliminates the need for separate stabilization systems, thereby reducing overall device complexity while maintaining high photographing stability.
3Reliability
If the parallelogram mechanism is driven to deform for vertical compensation, then vertical direction stabilization is improved, but the device complexity increases
Solution Approach 1:
The parallelogram mechanism serves as an intermediary between the driving component (motor) and the load-connecting member. It converts the rotational motion of the motor into vertical translational motion of the load, providing smooth and precise vertical compensation without requiring complex direct-drive mechanisms.
Solution Approach 2:
The patent replaces complex mechanical linkages with a motor-driven parallelogram mechanism that uses controlled deformation to achieve vertical motion. This substitution simplifies the overall structure by eliminating the need for traditional screw mechanisms or rack-and-pinion systems, thereby reducing device complexity while maintaining vertical stabilization capability.
