Ring-Shaped Head Support for Even Skull Pressure Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing head support devices fail to provide stable and comfortable support for infants and adults, leading to potential skull deformities due to inadequate pressure distribution and freedom of movement, which can exacerbate positional deformities such as plagiocephaly and brachycephaly.
Innovation Solution
A shaped body with a substantially ring-shaped, open design featuring an inclined half ellipse or asymmetrical convex support surface that increases the effective contact area with the head, allowing for better pressure distribution and freedom of movement, thereby reducing the risk of pressure-induced deformities and promoting comfortable positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a traditional head support device is used, then the head is supported, but the pressure distribution is inadequate and freedom of movement is restricted, leading to skull deformities
Solution Approach 1:
The support device features a ring-shaped design with varying cross-sectional contours that create different support zones. The inclined half-ellipse or asymmetrical convex contour provides targeted pressure distribution across different regions of the head, ensuring stable support while avoiding excessive pressure on any single point, thus preventing deformities.
Solution Approach 2:
The support device allows dynamic adjustment of head position through its ring-shaped structure with inclined contours. The design enables the head to move naturally within a controlled range while maintaining stable support, accommodating freedom of movement without compromising support reliability.
2Object-affected harmful factors
If the head is restrained to prevent deformities, then positional deformities are reduced, but freedom of movement is limited
Solution Approach 1:
The support device is designed as an open ring-shaped structure rather than a complete enclosure. This segmented design provides support and deformation prevention at critical areas while leaving other areas free for natural head movement, thus balancing protection with freedom of movement.
Solution Approach 2:
The support device employs an asymmetrical convex contour or inclined half-ellipse cross-section that provides targeted support where needed while maintaining openness and flexibility elsewhere. This asymmetrical design allows the head to move naturally in permitted directions while preventing deformities in supported regions.
3Reliability
If a rigid support structure is used, then stable support is provided, but comfort and adaptability are reduced
Solution Approach 1:
The support device utilizes changes in cross-sectional contour parameters, specifically the inclined half-ellipse or asymmetrical convex shape, to optimize both stability and comfort. These parameter variations allow the device to provide firm support where structurally sound while maintaining adaptability to different head shapes and positions.
