Foam Mattress Airflow Layout for Low-Loss Heating and Cooling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing foam mattresses face challenges in effectively and efficiently distributing heated or cooled air to the upper surface due to air pressure losses and temperature differential reductions, and combining comfort systems like heating, cooling, elevation, and firmness mechanisms complicates their operation.
Innovation Solution
The sleeping system incorporates air blowers positioned adjacent to the foundation's apertures, minimizing air flow paths and using direct communication to reduce pressure loss, along with a wireless control unit to manage heating, cooling, elevation, and firmness systems, and includes a flexible encasement dish with engineered springs for enhanced support and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If air blowers are used for convective heating or cooling of the mattress, then temperature adjustment capability is improved, but air pressure losses and temperature differential reductions occur during air distribution
Solution Approach 1:
The mattress is divided into multiple independent air channels with individual blowers for each section, allowing localized temperature control and reducing overall air pressure losses by treating each segment separately rather than distributing air through a single long path
Solution Approach 2:
Different sections of the mattress can have different temperature settings and air flow rates tailored to specific user preferences and body zones, optimizing thermal comfort while minimizing energy waste in areas that don't require intensive heating or cooling
2Adaptability or versatility
If multiple comfort systems (heating, cooling, elevation, firmness) are combined in a single sleeping system, then functionality and comfort options are improved, but operational complexity increases
Solution Approach 1:
A single control unit is designed to manage multiple comfort systems including heating, cooling, elevation, and firmness adjustments through a unified interface, allowing one device to perform multiple functions and reducing the number of separate controls users must interact with
Solution Approach 2:
Multiple control functions for different comfort systems are merged into a single integrated control unit with centralized processing, simplifying the user interface and reducing operational complexity while maintaining full functionality of all comfort features

AI summary
A sleeping system is described in which comfort systems for a foam mattress assembly are mounted in a foundation assembly supporting the mattress assembly. The comfort systems include an air heating and cooling system, a firmness system and an elevation system. The foam mattress assembly includes a flexible encasement dish into which one or more foam layers are disposed. Blowers for the air system are mounted adjacent the foundation assembly top in direct fluid communication with apertures in the top, minimizing the air flow path from the blower exhaust to the mattress top to reduce air pressure loss and diminishment of the heated or cooled air.
