Body Support Cushion Ventilation System for Sleep Temperature Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sleep technologies fail to effectively manage temperature fluctuations, leading to disrupted sleep, especially during summer months, as they do not adequately regulate body temperature, resulting in poor sleep quality and potential health risks.
Innovation Solution
A body support cushion with an integrated ventilation system that actively draws ambient air through the mattress, filters it, and maintains a constant surface temperature and humidity level by directing temperature-controlled airflow, preventing heat buildup and humidity, and allowing for adjustable temperature conditioning based on the user's profile.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If traditional mattress materials are used, then comfort and support are provided, but heat buildup and humidity occur leading to disrupted sleep
Solution Approach 1:
The patent implements a ventilation system with air movers, conduits, and chambers that actively circulate air through the mattress layers. This pneumatic system removes excess heat and humidity from the mattress surface, maintaining optimal temperature and preventing the heat buildup that disrupts sleep, thereby resolving the contradiction between thermal comfort and sleep quality reliability
Solution Approach 2:
The patent incorporates porous foam layers with interconnected cells that allow air permeation throughout the mattress structure. This porous material design enables efficient heat and moisture transfer while maintaining comfort and support, solving the contradiction by allowing thermal regulation without compromising the mattress's supportive function
2Temperature
If ventilation channels are added to the mattress, then temperature regulation improves, but structural complexity increases
Solution Approach 1:
The patent merges the ventilation channels with the existing foam layer structure, integrating air movers, conduits, and chambers into the mattress layers rather than adding separate components. This consolidation achieves effective temperature regulation while minimizing structural complexity by combining multiple functions within unified structural elements
Solution Approach 2:
The foam layers serve multiple functions simultaneously: providing comfort and support through their viscoelastic properties, while also serving as structural passageways for air flow and heat transfer. This multi-functionality reduces overall device complexity by eliminating the need for separate ventilation structures
3Loss of energy
If active ventilation system is implemented, then heat removal efficiency increases, but energy consumption increases
Solution Approach 1:
The patent employs air movers that operate in periodic cycles rather than continuously, creating pulsating air flow through the mattress layers. This periodic operation maintains effective heat and humidity removal while significantly reducing energy consumption compared to continuous operation, resolving the contradiction between heat removal efficiency and energy use
