Foldable Handheld Gimbal Structure for Compact Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional handheld gimbals are not compact enough for storage, leading to complex storage procedures and the need to separate the gimbal and photographing apparatus, due to gaps between components and the inability of the clamping portion to secure the apparatus after folding.
Innovation Solution
A handheld gimbal design featuring a handle with a top and bottom portion, a first shaft assembly, a second shaft assembly, a third shaft assembly, and a rotatable connecting member that allows the first and second shaft arms to fold along the connecting member, reducing gaps and enabling compact storage while maintaining the ability to secure the photographing apparatus.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the first connecting arm is folded downward and the second connecting arm is folded to keep parallel with the handle, then the total length and volume of the handheld stabilizer are reduced, but gaps remain between components making it not compact enough for storage
Solution Approach 1:
The first connecting arm is nested within the second connecting arm when folded, creating a compact configuration where components are stored within each other rather than merely adjacent, significantly reducing the overall storage volume and eliminating gaps between components
Solution Approach 2:
The clamping portion is designed to dynamically adjust its position and orientation during the folding process, maintaining clamping capability on the photographing apparatus throughout the transition from use state to storage state, rather than being a static structure that loses function when folded
2Volume of moving object
If the clamping portion is folded, then the total volume is reduced, but the clamping portion cannot continue to clamp the photographing apparatus
Solution Approach 1:
The clamping portion is designed with dynamic adjustment capability that allows it to maintain clamping force on the photographing apparatus throughout the folding process, adapting its position and orientation as the structure transitions from use to storage state, rather than being a static structure that loses function when folded
Solution Approach 2:
The clamping portion is positioned and oriented in advance during the folding sequence to ensure continuous contact with the photographing apparatus, preparing the clamping action before the folding is complete so that the apparatus remains secured throughout the entire storage transition
3Volume of moving object
If the first shaft arm and second shaft arm are folded along the rotatable connecting member, then gaps between components are reduced making the gimbal more compact, but the structure becomes more complex
Solution Approach 1:
The first shaft arm is nested within the second shaft arm configuration when folded along the rotatable connecting member, allowing compact storage by placing one component within the spatial envelope of another, reducing gaps and achieving a more compact form factor
Solution Approach 2:
The rotatable connecting member serves multiple functions simultaneously: it connects the first and second shaft arms, enables the folding motion, and acts as the axis for the nested configuration, merging several structural elements into one integrated component that reduces overall complexity
