Efficient mattress having low pressure and alignment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mattresses fail to provide adequate low pressure and alignment, leading to restless sleep due to excessive pressure on body protrusions and spinal misalignment, resulting in frequent body shifts and disrupted sleep patterns.
Innovation Solution
A mattress design featuring a performance layer with varying displacement parameters, including a first shoulder section, a first thoracic section, a hip section, and a second thoracic section, supported by a core layer, which conforms to the body's displacement profile to maintain spinal alignment and reduce pressure below the ischemic threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stress or pressure
If conventional mattresses are used, then they provide basic support, but they cause excessive pressure on body protrusions leading to frequent body shifts
Solution Approach 1:
The mattress is divided into multiple zones with different foam densities and displacement parameters. High-density foam is placed in regions requiring more support (shoulders, hips) while lower-density foam is used in areas needing more contouring. This local differentiation of material properties reduces pressure on body protrusions while maintaining overall support, thereby reducing body shifts and improving sleep continuity.
Solution Approach 2:
The mattress is segmented into distinct sections (head, shoulder, thoracic, lumbar, hip, leg regions) with varying foam characteristics. Each segment is designed to independently respond to body pressure, allowing the mattress to adapt to the complex geometry of the human body. This segmentation enables targeted pressure reduction at high-pressure areas without compromising support elsewhere, reducing the need for body shifts.
2Stability of the object's composition
If conventional mattresses are used, then they provide uniform support, but they cause spinal misalignment due to inability to conform to body displacement profile
Solution Approach 1:
Different regions of the mattress have locally optimized foam properties matched to the specific anatomical requirements of each body region. The thoracic and lumbar regions, which require maintained alignment, use higher-density foam with lower displacement, while shoulder and hip regions use lower-density foam with higher displacement to accommodate body contours. This local quality differentiation simultaneously achieves spinal alignment stability and adaptability to body displacement profile.
Solution Approach 2:
The mattress utilizes systematic variation of foam parameters (density, ILD, thickness) across different zones to match the body's displacement profile. By changing these physical parameters spatially, the mattress achieves both conformity to body contours and maintenance of proper spinal alignment, resolving the contradiction between adaptability and stability.
3Stress or pressure
If mattress sections have varying displacement parameters to match body profile, then pressure is reduced and alignment is maintained, but manufacturing complexity increases
Solution Approach 1:
The mattress is constructed by segmenting the foam into distinct sections that can be manufactured separately using standard foam cutting and assembly processes. Each segment corresponds to a specific body region and can be produced independently, then assembled into the final mattress. This segmentation approach maintains manufacturing simplicity while enabling the varying displacement parameters needed for pressure reduction and alignment.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The mattress effectively reduces body shifts and improves sleep quality by maintaining spinal alignment and low surface pressure, enhancing restful sleep by minimizing disruptions and promoting deeper, more restorative sleep stages.
Implementation Method 1
The mattress includes a performance layer, and a core layer disposed below the performance layer configured to support the performance layer. The performance layer, along the longitudinal direction, includes a first shoulder section with first shoulder displacement parameters, a first thoracic section with first thoracic displacement parameters, and a hip section with hip displacement parameters

AI summary
Provided herein is a mattress that efficiently provides low pressure and alignment to achieve restful and less fragmented sleep to a recumbent body. The mattress comprises a composite and a cover encapsulating the composite. The composite includes a performance layer and a core layer. The performance layer includes a first shoulder section, a first thoracic section and a hip section for location at different longitudinal positions corresponding to the shoulder region, the thoracic region and the hip region of the recumbent body. The first shoulder section, the first thoracic section and the hip section have different displacement parameters to match the body displacements in the shoulder region, the thoracic region, and the hip region for alignment of the body with low body pressure. The performance layer may further comprise a second thoracic section and a second shoulder section. A core layer supports the performance layer.
