Negative pressure mattress system
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mattresses fail to create negative pressure to draw ambient air away from the sleeping surface, which affects temperature regulation and comfort during sleep.
Innovation Solution
A bedding system with a box layer, capacitor layer, and mattress layer, incorporating ducts, inlets, and a central vacuum system to draw air away from the sleep surface using negative pressure, thereby regulating temperature.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional mattresses are used, then the structure is simple and easy to manufacture, but the temperature regulation capability is poor
Solution Approach 1:
The mattress is divided into multiple functional layers including a box layer with ducts, a capacitor layer with cavities, and a mattress layer with holes. This segmentation allows each layer to perform specific functions related to air flow and temperature regulation, resolving the contradiction by creating a complex but organized multi-layer structure that achieves temperature control.
Solution Approach 2:
The system uses a central vacuum system with power units to create negative pressure, drawing air through ducts, cavities, and holes in the mattress layers. This pneumatic approach enables active temperature regulation by controlling air flow, transforming the mattress from a passive structure to an active thermal management system.
2Temperature
If a vacuum system is added to draw air away from the sleep surface, then temperature regulation is improved, but the device complexity increases
Solution Approach 1:
The central vacuum system with power units is integrated into the bedding system to serve multiple functions: temperature regulation, air circulation, and potential moisture control. This multi-functionality justifies the added complexity by consolidating several environmental control functions into a single integrated system.
Solution Approach 2:
The system employs a nested structure where the box layer with ducts contains the capacitor layer with cavities, which in turn supports the mattress layer with holes. The vacuum system is nested within this layered structure, with power units positioned to access air through the various layers. This nesting allows compact integration of multiple components, managing complexity through organized hierarchy.
