Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current professional photographing devices with large weights face difficulties in accurately adjusting the center of gravity due to the absence of fine adjusting mechanisms and high friction, leading to poor connection reliability during frequent adjustments in varying shooting environments.
Innovation Solution
A gimbal frame equipped with a center of gravity adjusting and locking mechanism, comprising a sleeve, a moving member, and an operating member, which allows for precise adjustment and locking of the center of gravity through a guide rod, enabling stable posture maintenance of the photographing device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a traditional center of gravity adjusting mechanism is used with a heavy photographing device, then the adjusting mechanism can support the weight, but the friction is large and accurate adjustment is difficult
Solution Approach 1:
The adjusting mechanism is divided into multiple independent components: a movable component that slides on the guide rod, a locking component with locking teeth, and a fine-adjustment screw. This segmentation allows each component to perform its specific function with reduced friction - the movable component handles coarse adjustment while the fine-adjustment screw provides precise positioning with minimal friction interference
Solution Approach 2:
The guide rod serves as an intermediary element between the movable component and the photographing device. It provides a low-friction sliding surface that enables smooth movement of the center of gravity while maintaining structural stability. The guide rod's precise machining ensures minimal friction and high adjustment accuracy
2Adaptability or versatility
If the photographing device is frequently demounted and mounted, then adaptability to different shooting environments is improved, but the center of gravity adjustment needs frequent readjustment which is difficult to control
Solution Approach 1:
The center of gravity adjusting mechanism incorporates a dynamic locking system with locking teeth that can quickly engage and disengage. The movable component can be freely positioned along the guide rod and then securely locked in place, allowing rapid adaptation to different shooting configurations without complex adjustment procedures
Solution Approach 2:
The guide rod is pre-positioned and precisely machined to provide reference alignment for the movable component. This preliminary preparation ensures that when the photographing device is remounted, the center of gravity adjustment can be quickly restored to the correct position without requiring complete re-adjustment of all parameters
3Ease of operation
If the center of gravity adjusting mechanism is simplified, then ease of operation is improved, but connection reliability deteriorates
Solution Approach 1:
The locking teeth are designed with curved surfaces that provide smooth engagement and disengagement. The arc-shaped locking surfaces reduce stress concentration and enable reliable locking with minimal operational force, maintaining both ease of operation and connection reliability
Solution Approach 2:
The adjusting mechanism incorporates built-in cushioning elements that absorb shock and prevent sudden impacts during locking and adjustment operations. This cushioning protects the connection reliability by preventing stress concentration and damage to the locking components during frequent adjustments

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mechanism allows for accurate and controlled adjustment of the center of gravity, enhancing the stability and reliability of the gimbal frame, even with heavy loads, by converting rotary motion into axial movement for secure locking, thus maintaining the photographing device in a preset posture effectively.
Implementation Method 1
an operating member coupled to the sleeve and in transmission connection with the moving member. When the operating member is operated, the moving member is driven to move towards the guide rod
Implementation Method 2
the moving member is driven to move towards the guide rod so as to tightly abut against the at least one guide rod
