Solution Overview

Problem

Existing gimbal systems face challenges in quickly adjusting the center of gravity of loads, such as cameras, relative to the gimbal, which can lead to unexpected torque on the motor, affecting user experience and the operational life of the gimbal.

Innovation Solution

A gimbal load mounting assembly with a first seating body and a second seating body that are slidable relative to each other, equipped with adjustment devices to drive movement between the seating bodies, allowing for quick adjustment of the load's mounting location and center of gravity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the load is mounted on a fixed position on the gimbal, then the structure is simple and stable, but the center of gravity cannot be adjusted quickly, leading to unexpected torque on the motor

Engineering Contradiction:
Improveadjustment speed of center of gravityVSAvoidmounting assembly structure
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The mounting assembly transforms from a static fixed structure to a dynamic adjustable structure. The second seating body can slide along the first seating body in the first direction, and the first seating body can slide along the second direction, enabling dynamic adjustment of the load's center of gravity position to match different operational requirements

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The mounting assembly is divided into multiple independent seating bodies (first seating body and second seating body) that can move relative to each other. This segmentation allows independent adjustment of each seating body's position, providing flexible center of gravity adjustment while maintaining structural modularity

Inventive Principle:
Principle #1Segmentation

2Reliability

If the center of gravity of the load is not aligned with the rotating shaft, then the mounting is simple, but unexpected torque is exerted on the driving motor, affecting user experience and operational life

Engineering Contradiction:
Improveoperational life of gimbalVSAvoidquick adjustment capability
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The adjustment device allows the user to pre-adjust the center of gravity position before operation. By moving the second seating body along the first seating body and the first seating body along the second direction, the system enables preliminary centering of the load's center of gravity on the rotating shaft, preventing torque issues during operation

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The first and second seating bodies act as intermediary elements between the load and the gimbal's rotating shaft. These seating bodies provide a mechanism to position the load's center of gravity precisely at the rotating shaft location, mediating the connection to eliminate harmful torque while maintaining operational flexibility

Inventive Principle:
Principle #24Intermediary (Mediator)
