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 can lead to temperature regulation issues affecting comfort and quality of sleep.
Innovation Solution
A bedding system comprising a box layer with ducts and inlets, a capacitor layer with a cavity, a mattress layer with holes communicating with the cavity, a temperature sensor, and a central vacuum system that creates negative pressure to draw air away from the sleep surface when the temperature drops below a threshold.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If conventional mattresses are used, then the structure is simple, but the temperature regulation capability is insufficient
Solution Approach 1:
The mattress system is divided into multiple functional layers: a box layer with ducts for air intake, a capacitor layer with cavities for air storage, and a mattress layer with holes for air passage. This segmentation allows each layer to perform its specific function in the temperature regulation process, enabling effective heat removal while maintaining a manageable overall structure.
Solution Approach 2:
A vacuum system acts as an intermediary component to create negative pressure that draws warm air away from the sleep surface through the ducts and cavities. This intermediary mechanism enables temperature regulation without requiring complex internal mattress structures, as the vacuum system handles the active air movement function.
2Temperature
If a vacuum system is added to regulate temperature, then temperature control is improved, but the device complexity increases
Solution Approach 1:
A temperature sensor is integrated into the mattress layer to continuously monitor the sleep surface temperature. When the temperature exceeds a predetermined threshold, the sensor triggers the vacuum system to activate, creating negative pressure to remove excess heat. This feedback mechanism ensures temperature regulation occurs only when needed, avoiding unnecessary operation of the vacuum system and reducing overall system complexity.
Solution Approach 2:
The system uses the body's own heat to drive the temperature regulation process. The temperature sensor detects when the sleep surface becomes too warm due to body heat, and the vacuum system automatically activates to remove this excess heat, creating a self-regulating system that responds to the user's thermal needs without external control.
