Handheld Head Mount Clamp Structure for Center of Gravity Alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The clamping mechanism of handheld head mounts fails to adjust the center of gravity of photographing devices during use, leading to increased motor load, power consumption, and user discomfort due to the deviation of the device's center of gravity from the preset center of the handheld head.
Innovation Solution
A clamping mechanism with adjustable clamps that maintain a constant clamping width while allowing the spacing between the clamps and the main body to be adjusted, enabling the center of gravity to be aligned with the gripping center, using a thread adjustment structure for convenient operation and an elastic clamping mechanism for comfortable use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the clamping mechanism uses a fixed symmetric structure with clamps centered on the main body, then the structure is simple and easy to manufacture, but the center of gravity of the photographing device cannot be adjusted and deviates from the preset center of gravity of the handheld head mount
Solution Approach 1:
The patent applies asymmetry by making one clamp (first clamp) movable relative to the main body while the other clamp (second clamp) remains fixed. This asymmetric configuration allows the clamping center to be adjusted along the clamping direction, enabling adaptation to different center of gravity positions of photographing devices while maintaining a relatively simple overall structure.
2Adaptability or versatility
If the clamping mechanism allows adjustment of clamp position to align center of gravity, then adaptability and user comfort improve, but the device complexity increases due to additional adjustment mechanisms
Solution Approach 1:
The patent segments the clamping mechanism into a fixed portion (main body with second clamp) and a movable portion (first clamp that can slide along the clamping direction). This segmentation allows independent adjustment of the first clamp's position while keeping the rest of the structure stable, achieving center of gravity adaptation with minimal added complexity.
Solution Approach 2:
The patent introduces dynamic adjustability by allowing the first clamp to move relative to the main body in the clamping direction. This dynamic feature enables the clamping center to be repositioned according to the photographing device's center of gravity location, providing adaptability without requiring complete structural redesign.
3Stability of the object's composition
If the clamping mechanism maintains constant clamping width while adjusting clamp position, then photographing device stability is improved, but the mechanism complexity increases due to width maintenance requirements
Solution Approach 1:
The patent applies local quality by maintaining constant clamping width (local dimension) while allowing adjustment in the clamping direction (global position). The first clamp's movement is constrained to maintain its perpendicular distance from the clamping direction, ensuring stable clamping of the photographing device while adapting the clamping center position.

Implementation Method 1
a resilient biasing member disposed between the slider and the receiving cavity, wherein the elastic biasing force of the resilient biasing member acts on the slider
Implementation Method 2
a screw threadedly engaged with the internal thread structure, wherein the screw is rotated to drive the clamp to reciprocate toward or away from the direction of the main body
