Solution Overview

Problem

Existing handheld gimbals require manual adjustment of the center of gravity of mounted devices, such as mobile phones or cameras, to align with gimbal axes, which is inconvenient and time-consuming.

Innovation Solution

A magnet-based quick release assembly and gimbal system that utilizes attraction members, such as magnets, to detachably mount devices, allowing automatic alignment and quick attachment to the gimbal, with the attraction members causing the connector assembly and mounting structure to rotate into the correct position.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual adjustment of device position is used to align center of gravity with gimbal axes, then proper alignment can be achieved, but it is inconvenient and time-consuming

Engineering Contradiction:
Improvealignment precisionVSAvoidadjustment time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The magnetic connector assembly automatically aligns itself with the mounting structure through magnetic attraction when brought into proximity. The magnetic force causes the connector assembly to rotate and snap into the correct position, eliminating the need for manual adjustment of the device position to align center of gravity with gimbal axes.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces manual mechanical adjustment with magnetic field-based automatic alignment. The magnetic attraction between the connector assembly and mounting structure substitutes for the manual mechanical positioning process, enabling automatic alignment through magnetic force rather than human intervention.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Manufacturing precision

If manual adjustment is required for each mounting, then proper center of gravity alignment can be achieved, but the operation becomes complex and repetitive

Engineering Contradiction:
Improvecenter of gravity alignmentVSAvoidmounting convenience
Core Design Contradiction:
Manufacturing precisionVSEase of operation

Solution Approach 1:

The magnetic connector assembly performs self-alignment when brought near the mounting structure. The magnetic force automatically orients the connector assembly in the correct position, making the mounting process as simple as bringing the components close together, thereby greatly improving ease of operation.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent extracts the complex adjustment process from the mounting operation. By incorporating magnetic alignment into the connector assembly design, the difficult manual adjustment step is removed from the user's task, leaving only the simple action of bringing components into proximity.

Inventive Principle:
Principle #2Taking out (Extraction)

3Adaptability or versatility

If the mobile phone clip is made removable, then device versatility is improved, but connection stability may be compromised

Engineering Contradiction:
Improvedevice interchangeabilityVSAvoidconnection stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The magnetic connector assembly uses curved or rounded magnetic poles that create a distributed magnetic field. This curved magnetic interface provides both detachability for versatility and stable connection through the distributed magnetic attraction across the curved surface, preventing accidental disconnection.

Inventive Principle:
Principle #14Spheroidality (Curvature)

Solution Approach 2:

The magnetic connector assembly is pre-configured with specific magnetic pole arrangements that create strong attraction forces. This preliminary design ensures that when devices are mounted, the magnetic connection provides stable, reliable attachment that maintains connection stability while allowing intentional removal.

Inventive Principle:
Principle #10Preliminary action
