Negative Space Bed Structure for Side Sleeper Arm Support
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional mattress designs fail to provide adequate three-dimensional support for the human body, leading to discomfort and pain, especially for side and stomach sleepers, due to the lack of space for arm and neck movement, and insufficient support for shared sleeping arrangements.
Innovation Solution
A bed design featuring a negative space channel in the upper torso area that allows for three-dimensional movement of arms and shoulders, with a foundation layer, cushion layer, and upper layer configuration, including channel pillows and support layers to provide customized support and comfort, while maintaining a rectangular footprint.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional flat mattress design is used, then the manufacturing is simple and the footprint is rectangular, but the comfort and support for the human body is insufficient due to lack of three-dimensional space
Solution Approach 1:
The patent introduces a negative space channel that extends vertically into the mattress structure, transforming the traditional two-dimensional flat surface into a three-dimensional configuration. This channel creates void space that allows body parts to sink in and be supported at multiple levels, providing anatomical support while maintaining a rectangular footprint from above.
Solution Approach 2:
The negative space channel is formed within the existing mattress structure by removing material, creating a nested void space inside the solid mattress body. This allows the channel to be integrated into the mattress without adding external complexity, maintaining ease of manufacture while enabling three-dimensional support.
2Device complexity
If a traditional flat mattress design is used, then the structure is simple, but the space for arm and neck movement is insufficient causing discomfort
Solution Approach 1:
The negative space channel creates vertical dimensionality within the mattress, allowing arms and neck to move freely in the void space while the overall mattress structure remains simple and rectangular from a top-down view.
3Area of stationary object
If a traditional flat mattress design is used, then the footprint is compact, but the support for shared sleeping arrangements is insufficient due to overlapping space requirements
Solution Approach 1:
The negative space channel is positioned to accommodate body parts from multiple sleepers simultaneously. The channel acts as a shared void space where arms, necks, and shoulders from different sleepers can be supported without requiring additional horizontal space, enabling comfortable shared use within the same footprint.

AI summary
A bed defining a negative space to accommodate side sleepers and stomach sleepers by providing a space into which the user's arms and shoulders can extend. Channel pillows can be placed inside the negative space to provide support for the user's head while allowing the user's hands and shoulders to slide in between the channel pillow and the wall that define the negative space. The negative space is formed into a foundation having an upper torso region, a lower torso region, and a transition region therebetween. The transition region can comprise an angled wall. A cushion layer with a slanted wall is configured to cover the transition region and lower torso region of the foundation. An upper, comfort layer can be provided with a cutout that aligns with the negative space when placed on top of the foundation and cushion layer.
