Mattress Humidity Control Using Integrated Drying Module and Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mattresses, particularly spring mattresses, lack adjustability in firmness and suffer from vibration transmission and humidity issues, leading to discomfort and potential mold growth due to inadequate moisture control.
Innovation Solution
A bed system featuring a mattress with adjustable firmness through height-adjustable inner springs and a built-in drying module that uses a fan system to dry the mattress, maintaining a comfortable humidity level and preventing mold growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional spring mattress is used, then the mattress provides basic cushioning support, but the firmness cannot be adjusted and vibrations are transmitted between springs causing discomfort
Solution Approach 1:
The mattress is divided into multiple independent spring modules, each capable of independent adjustment. This segmentation allows each module to be adjusted individually for firmness while preventing vibration transmission between modules, resolving the contradiction between adaptability and complexity.
Solution Approach 2:
The spring modules are designed with adjustable height mechanisms that allow dynamic modification of firmness. Users can adjust the height of each spring module to change the firmness level, transforming a static mattress into a dynamically adjustable system that adapts to different users' needs.
2Duration of action of stationary object
If the mattress is used in humid conditions, then the mattress provides continuous support, but moisture accumulates causing discomfort and mold growth
Solution Approach 1:
A drying module is integrated into the mattress system that proactively removes moisture before mold can grow. The drying module includes air circulation components that continuously or periodically dry the mattress surface, preventing the accumulation of harmful moisture levels.
Solution Approach 2:
The drying module acts as an intermediary system between the mattress and the humid environment. It introduces dry air circulation that mediates the interaction between the mattress and ambient humidity, protecting the mattress from moisture damage while maintaining continuous support functionality.
3Adaptability or versatility
If multiple users share the same mattress, then the mattress serves multiple people, but different users have different firmness preferences that cannot be accommodated
Solution Approach 1:
The mattress is segmented into multiple independently adjustable spring modules that correspond to different body regions. Each user can adjust the firmness of modules in their preferred sleeping position, allowing multiple users with different preferences to share the same mattress while each having personalized firmness control.
Solution Approach 2:
Different regions of the mattress can have different firmness settings, allowing each user to customize the local quality of support in their preferred areas. This enables multi-user compatibility while maintaining ease of operation through localized adjustment capabilities.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system allows for customizable firmness and effective moisture control, enhancing sleep comfort by reducing vibrations and preventing mold, ensuring a dry and pleasant sleeping surface.
Implementation Method 1
A dryer or drying module may supply dry air into the mattress set
Implementation Method 2
a blowing device may be mounted below the set support. The blowing device may include a blowing fan, a suction duct connected to a suction port of the blower fan and suctioning ambient air through suction ports formed at both ends, and a supply duct connected to the discharge port of the blowing fan to supply suctioned ambient air to the mattress set

AI summary
A bed includes a mattress set on which a user's body is placed, an adjustable bedframe to adjust a position or orientation of the mattress set for various sitting and sleeping positions, and a dryer to dry the mattress set. The dryer includes a fan, a filter, and a heater to discharge filtered hot air toward the dryer to reduce mildew and mites. A humidity sensing sheet may be provided to sense a humidity level at different regions or areas of the bed, and the dryer may be controlled to supply hot air to regions of the bed having a higher humidity level than a predetermined humidity level or humidity range.
