Solution Overview

Problem

Conventional gimbals do not provide stabilization for photography devices against vibrations in the direction of gravity, leading to image jitter during photography.

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 and counteract vibrations in the vertical direction, thereby stabilizing the photography device.

Engineering Contradictions & Design Principles

VSEngineering 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 gravity direction, leading to image jitter

Engineering Contradiction:

Improvestabilization capabilityVSAvoidvibration in gravity direction

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The stabilization system is divided into two independent parts: a conventional gimbal mechanism for rotational stabilization and a linear actuator mechanism for vertical stabilization. The load-connecting member is segmented to connect to both the gimbal and the actuator, allowing independent operation of each stabilization function.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A load-connecting member serves as an intermediary component that connects the photographing device to both the gimbal mechanism and the linear actuator. This intermediary allows the transfer of stabilization forces from both mechanisms to the photographing device, enabling combined rotational and vertical stabilization.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Stability of the object's composition

If a gimbal mechanism is used, then rotational stabilization is achieved, but the structure cannot provide stabilization against gravity-direction vibrations without additional components

Engineering Contradiction:

Improverotational stabilityVSAvoidstructural simplicity

Core Design Contradiction:

Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent merges the conventional gimbal mechanism with a linear actuator mechanism into a single integrated stabilization apparatus. The load-connecting member connects both mechanisms, allowing them to work together as a unified system that provides both rotational and vertical stabilization without requiring separate independent systems.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The load-connecting member is designed as a universal connection component that interfaces with both the gimbal's rotating arms and the linear actuator's moving platform. This multi-functional component allows a single structure to receive and transmit forces from multiple stabilization mechanisms simultaneously.

Inventive Principle:

Principle #6Universality (Multi-functionality)
