Solution Overview

Problem

The cumbersome process of mounting a load device, such as a mobile phone or camera, onto a gimbal for shooting tasks increases preparation time and user frustration due to the need for manual adjustments to achieve a ready-for-shooting state.

Innovation Solution

A gimbal control method that includes controlling the arm assembly to maintain a stable attitude during load device mounting, automatically adjusting to a shooting-ready position, and simplifying the preparation process by automatically opening the control application and establishing communication connections.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Manufacturing precision

If manual adjustments are required to combine the load device with the gimbal, then the gimbal can be precisely positioned, but the preparation time increases and user experience deteriorates

Engineering Contradiction:
Improvepositioning precisionVSAvoidpreparation time
Core Design Contradiction:
Manufacturing precisionVSLoss of time

Solution Approach 1:

The gimbal performs preliminary actions by automatically positioning the arm assembly to a predetermined angle and opening the control application before the user completes the mounting process. This preliminary automation reduces the manual adjustment time while maintaining positioning precision, directly resolving the contradiction between preparation time and positioning accuracy.

Inventive Principle:
Principle #10Preliminary action

2Adaptability or versatility

If manual adjustments are required to achieve ready-for-shooting state, then the shooting configuration can be optimized, but the operation complexity increases

Engineering Contradiction:
Improveshooting configurationVSAvoidoperation simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

The gimbal system performs self-service by automatically positioning the arm assembly and opening the control application without requiring manual user input. This automation maintains the optimized shooting configuration while significantly simplifying the operation, allowing users to simply mount the device and have the system handle the complex positioning and setup procedures automatically.

Inventive Principle:
Principle #25Self-service

3Productivity

If automatic positioning is implemented, then the preparation time is reduced, but the control complexity increases

Engineering Contradiction:
Improvemounting efficiencyVSAvoidcontrol system complexity
Core Design Contradiction:
ProductivityVSDevice complexity

Solution Approach 1:

The control device implements feedback mechanisms to detect when the arm assembly reaches the predetermined angle and when the load device is properly mounted. This feedback system automatically triggers the positioning and application opening sequences, reducing preparation time while managing control complexity through automated detection and response rather than requiring complex manual control systems.

Inventive Principle:
Principle #23Feedback
