Rotating Mechanism Neck Brace for Adjustable Head Posture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional neck braces are bulky, inflexible, and not suitable for healthy individuals, as they restrict head movement and cannot be adjusted to accommodate different postures or prevent myopia.
Innovation Solution
A lightweight neck brace with a rotating mechanism, adjustable head bracing member, and support member that can be adjusted to maintain a correct head posture, prevent myopia, and reduce pressure on the neck.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If conventional neck braces are designed to support the head and prevent movement, then neck pressure is reduced, but head mobility and adaptability are restricted
Solution Approach 1:
The patent applies the dynamics principle by designing a neck brace with a rotating mechanism that transitions from a fixed structure to a dynamic, adjustable one. The head bracing member can rotate relative to the support member, allowing the brace to adapt to different head positions and movements while still providing support. This resolves the contradiction by enabling both neck pressure reduction and head mobility through controlled rotation capability.
Solution Approach 2:
The neck brace is segmented into multiple functional components: a support member for torso attachment, a head bracing member for head support, and a rotating mechanism connecting them. This segmentation allows each component to perform its specific function independently - the support member provides stable anchoring, the head bracing member maintains contact with the head, and the rotating mechanism enables adaptive positioning. This modular structure resolves the contradiction between stability and mobility.
2Reliability
If conventional neck braces are designed for patient rehabilitation, then neck support is provided, but device complexity and bulkiness increase
Solution Approach 1:
The patent extracts only the essential support function from complex conventional neck braces. By removing unnecessary bulky components and focusing on the core function of weight distribution, the design achieves reliable neck support with minimal structure. The rotating mechanism is kept simple, using basic rotational joints rather than complex locking systems, thereby reducing overall device complexity while maintaining support reliability.
Solution Approach 2:
The patent changes key design parameters from conventional neck braces: reducing the overall size and weight, simplifying the adjustment mechanism to a simple rotation joint, and using lightweight materials. These parameter changes enable the device to provide reliable neck support without the bulkiness and complexity of traditional rehabilitation braces, making it suitable for healthy individuals seeking posture correction.
3Stability of the object's composition
If fixed angle neck braces are used, then head posture is maintained, but adaptability to different postures is lost
Solution Approach 1:
The rotating mechanism transforms the fixed-angle constraint into a dynamic system. The head bracing member can rotate to different angles while still maintaining contact with the head, allowing the user to adapt to different postures (looking down, looking up, turning head) while the brace continuously provides support. This dynamic capability resolves the contradiction between maintaining stable posture and adapting to different positions.

AI summary
A lightweight neck brace includes a head bracing member, a support member and a rotating mechanism rotatably couple the head bracing member and the support member between an adjustment state and a free state. The rotating mechanism enables the lightweight neck brace to be operable to switch between the adjustment state and the free state. In the adjustment state, the head bracing member can only be adjusted away from the support member, such that a height position of the supported head cannot be lowered. In the free state, the head bracing member can be adjusted away from the support member or close to the support member as desired.
