Adjustable Camera Support Frame for Hands-Free Stable Shooting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users experience discomfort when holding photographic equipment for extended periods due to the strain on their hands and arms, as existing solutions do not provide adequate support or ergonomic adjustments.
Innovation Solution
A support frame with a leg adjustment structure, pan-tilt connectors, and angle adjustment mechanisms that allow for unfolding and locking of secondary legs, enabling a three-leg support state and various mounting configurations to free hands and adjust camera angles.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If handheld photographing is used for long time, then photographing convenience is improved, but user comfort deteriorates due to hand and arm strain
Solution Approach 1:
The support frame employs dynamic leg structures that can transition between folded and unfolded states. The secondary leg includes sub-legs that can be unfolded to provide additional support points, allowing the device to adapt from a compact handheld form to a stable three-leg support configuration, thereby eliminating hand strain during extended use
Solution Approach 2:
The support frame is divided into modular components including primary leg, secondary leg with sub-legs, and adjustable connectors. This segmentation allows independent adjustment of each leg segment to achieve optimal support configuration, enabling users to switch between handheld mode and stable three-leg support mode to prevent hand and arm fatigue
2Ease of manufacture
If fixed support frame structure is used, then manufacturing simplicity is improved, but adaptability to different use scenarios deteriorates
Solution Approach 1:
The support frame incorporates adjustable connectors and leg mechanisms that enable dynamic reconfiguration between different support modes (handheld, three-leg support, hanging). These mechanisms maintain relatively simple manufacturing while providing multiple stable configurations through mechanical adjustment rather than complex modular assembly
Solution Approach 2:
The support frame is designed as a multi-functional device that can serve multiple purposes: handheld photographing, stable three-leg support for extended periods, and hanging configuration. The same structural components are used across all modes through adjustment rather than requiring separate specialized structures for each function
3Stability of the object's composition
If adjustable leg mechanisms are added, then support stability is improved, but device complexity increases
Solution Approach 1:
The leg adjustment mechanisms allow the support frame to dynamically adapt its stability characteristics. When three-leg support is needed, the sub-legs unfold to create a stable triangular base. The mechanisms use simple mechanical connections that provide inherent stability through geometry rather than requiring complex locking systems or additional structural reinforcements

Function Achieved in This Case
The support frame allows for comfortable long-term use by providing adjustable support and multiple use modes, including handheld, three-leg, and hanging configurations, reducing user fatigue and enhancing ergonomic handling.
Implementation Method 1
a damping shaft configured to pass through a damping hole of the first sub-leg and a damping hole of the second sub-leg, wherein each of inner walls of the damping hole of the first sub-leg and the damping hole of the second sub-leg is provided with a first limiting rib extending along the axial direction of the each inner wall, and the first limiting rib is configured to be limited in the first limiting groove which is located at outer circumferential surface of the damping shaft
Implementation Method 2
the first elastic member is configured to enable teeth on the second crankset to mesh with teeth on the first crankset; the first button is configured to overcome an elastic force of the first elastic member under action of an external force

AI summary
The present disclosure relates to a support frame including a first pan-tilt connector and a leg assembly connected thereto and including a primary leg and a secondary leg. A leg adjustment structure is provided between and configured to unlock or lock the primary leg and the secondary leg, so that the primary leg and the secondary leg can move relative to each other or keep relatively stationary; the secondary leg comprises a first sub-leg and a second sub-leg which are configured such that the first sub-leg and the second sub-leg can be unfolded or folded with respect to each other; when the first sub-leg and the second sub-leg are unfolded, the primary leg, the first sub-leg and the second sub-leg are in a three-leg support state. The present disclosure further provides a photographing device, which comprises the support frame and an image acquisition apparatus mounted on the support frame.
