Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Handheld gimbals require users to connect a mobile phone to adjust follow parameters like speed and acceleration, which is time-consuming and inflexible, as settings are fixed once set and require a reset for changes.

Innovation Solution

A gimbal with a follow-configuration button and a processor that allows for on-device adjustment of follow parameters without the need for a mobile APP, enabling flexible changes by detecting the button trigger and adjusting settings accordingly.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If follow parameters are adjusted via mobile phone APP connection, then parameter adjustment capability is achieved, but operation time is increased and flexibility is reduced

Engineering Contradiction:

Improveparameter adjustment convenienceVSAvoidtime for connection and adjustment

Core Design Contradiction:

Ease of operationVSLoss of time

Solution Approach 1:

The patent extracts the parameter adjustment function from the mobile phone APP and relocates it directly to the gimbal device. The follow-configuration button and its associated processing unit are integrated into the gimbal, allowing users to adjust follow parameters (speed, acceleration) directly on the device without needing to connect a mobile phone, thereby eliminating the time-consuming connection process while maintaining full adjustment capability

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The gimbal becomes self-service capable by incorporating the follow-configuration button and processing unit directly into the device. The system can detect button triggers and adjust follow parameters autonomously without external mobile phone intervention, making the adjustment process independent and immediate

Inventive Principle:

Principle #25Self-service

2Stability of the object's composition

If follow parameters are set once, then device stability is maintained, but adaptability to changing conditions is reduced

Engineering Contradiction:

Improveparameter setting stabilityVSAvoidparameter change flexibility

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The patent implements dynamic parameter adjustment by allowing users to modify follow parameters (speed, acceleration) in real-time during operation through the follow-configuration button. The processing unit continuously monitors button inputs and updates parameters on-the-fly, transforming the system from a static, fixed-parameter mode to a dynamic, adaptable mode that can respond to changing shooting conditions without requiring complete resets

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The follow-configuration button is pre-configured with multiple parameter options (different speeds and accelerations) within the gimbal's memory. When triggered, the button provides immediate access to pre-prepared parameter sets, allowing instant switching between different follow characteristics without needing to connect to a mobile phone for configuration or perform complex reset procedures

Inventive Principle:

Principle #10Preliminary action

AI summary

A gimbal control method includes determining a current state of a follow-configuration button, determining a current follow coefficient based on the current state of the follow-configuration button, and controlling a gimbal to follow a target object according to the current coefficient. The follow-configuration button corresponds to a plurality of states, and each state corresponds to a different follow coefficient.
