Adjustable sleeping pillow that balances the body pressure ratio
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Modern sleeping pillows do not conform to human physiological curves, leading to discomfort during face-up and side sleeping due to inadequate filler distribution and deformation, which fails to adapt to the natural spinal curvature.
Innovation Solution
A sleeping pillow design with a pillow case that includes separate areas for head and neck support, featuring independent or interpenetrated zones for face-up and side sleeping, utilizing connecting and vertical partition cloths to maintain spinal alignment and adjust filler distribution for optimal comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the pillow uses a unified structure for both face-up and side sleeping, then the structure is simple, but it cannot adapt to different physiological curves of different sleeping positions
Solution Approach 1:
The pillow is divided into multiple functional regions including a first bearing area for face-up sleeping, a second bearing area for side sleeping, a partition board separating these areas, and an adding area for additional filler. This segmentation allows each region to be independently optimized for its specific sleeping position while maintaining overall pillow integrity.
2Adaptability or versatility
If the fillers are allowed to flow and deform freely, then the pillow adapts well to body curves, but the pillow loses its structural support and stability
Solution Approach 1:
The pillow case is designed as a flexible enclosure with specific structural features including the partition board and adding area. This flexible structure allows the fillers to deform and adapt to body contours while the partition board maintains structural integrity and prevents excessive filler migration, balancing adaptability with stability.
3Shape
If the pillow case is made with tight stitching, then the shape is maintained, but the fillers cannot deform to adapt to physiological curves
Solution Approach 1:
The pillow case employs different structural characteristics in different regions: the partition board provides rigid structural support to maintain overall shape, while the adding area and bearing regions allow greater filler deformation. This local differentiation enables simultaneous shape maintenance and adaptive deformation where needed.

AI summary
The present invention provides a kind of sleeping pillow complying with the spinal medical theories, including the pillow case and fillers. The space enclosed by the said pillow case is divided into the isolated head bearing area and neck bearing area, and the said head bearing area is divided into the middle dented face-up sleeping head bearing area and the side sleeping head bearing area whose sides are higher. The said neck bearing area is divided into the face-up sleeping neck bearing area set in the middle and the side sleeping neck bearing area set on both sides of the said face-up sleeping neck bearing area. The height of the said the side sleeping neck bearing area is not lower than that of the said face-up sleeping neck bearing area. The adjustable sleeping pillow in the present invention that makes the body pressure balanced has a standalone head bearing area and neck bearing area, which can avoid random movement of fillers to ensure the stability of the pillow shape; moreover, the head bearing area is provided with the face-up sleeping and side sleeping bearing areas at different heights, which make a human head feel naturally comfortable while a person is sleeping. The neck bearing area can make the neck closely fit to the sleeping pillow during side sleeping and face-up sleeping giving the neck a mild support force.
