Helmet Camera Boom Structure for Stable Adjustable Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing helmets with camera mounts struggle to provide a wide range of adjustment in camera positioning while maintaining comfort and minimizing relative motion between the camera and the wearer's head.
Innovation Solution
A helmet design featuring a brace member that arcs over the head, connecting to support pads and a boom with adjustable mounting options, allowing for precise camera positioning and reduced relative motion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a boom with adjustable mounting is provided to allow wide range of camera positioning adjustment, then adaptability is improved, but device complexity increases
Solution Approach 1:
The helmet is divided into functionally independent segments: a rigid helmet body, an adjustable boom assembly with multiple degrees of freedom, and a separate camera mounting interface. This segmentation allows the boom to provide wide positioning adjustment range while the helmet body maintains structural simplicity.
2Stability of the object's composition
If a rigid brace member is used to minimize relative motion between camera and head, then stability is improved, but comfort deteriorates due to pressing on the head
Solution Approach 1:
The helmet employs local quality differentiation where the brace member is rigid in the region spanning across the head to provide stability, while the contact areas with the wearer's head are made compliant through padding and flexible mounting interfaces. This allows the rigid structure to minimize camera movement while the localized compliant regions prevent discomfort.
3Strength
If support pads are made stiff to provide structural support, then strength is improved, but ease of manufacture deteriorates due to fitting complexity
Solution Approach 1:
The support pads incorporate dynamic adjustment mechanisms such as hinges and tensioning straps that allow the rigid pads to be adapted to different head sizes and shapes. The hinges enable the pads to flex during installation to conform to the wearer's head geometry, while the rigid structure is maintained during use to provide necessary support.

AI summary
A helmet (1) for carrying audio-visual equipment includes a brace member (18) having first and second ends (20, 22). The brace member passes in a spaced apart relationship from the left side of the head to the right side of the head of a wearer in use, until connecting at each end (20, 22) to a respective left or right side of the helmet (1). A boom (24) has a first boom end and a second boom end, the boom connecting at the first boom end to one of the first and second ends (20, 22) of the brace member (18). The boom includes a mounting for carrying at least one camera in a position near the head of a wearer. A method of capturing image data from a face and a power supply system for portable equipment are disclosed.
