Modular Spacer Textile Mattress for Machine-Washable Comfort
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional mattresses with spacer fabrics for enhanced comfort are too bulky for effective cleaning in standard washing machines, making them difficult to maintain hygiene.
Innovation Solution
A modular mattress design featuring elastic spacer textiles arranged within an elastic frame, allowing for detachment and separate cleaning of individual modules in a conventional washing machine, ensuring both comfort and ease of cleaning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If spacer fabric is made voluminous to achieve high lying comfort, then lying comfort is improved, but cleaning becomes difficult requiring manual or spray disinfection
Solution Approach 1:
The mattress is divided into modular components: a frame structure and multiple detachable spacer fabric inserts. Each insert can be removed individually from the frame and cleaned separately in a washing machine, eliminating the need for manual cleaning of the entire mattress while maintaining the comfort-providing voluminous spacer fabric structure.
2Reliability
If spacer fabric is made voluminous to achieve high lying comfort, then air permeability and microclimate are improved, but the mattress becomes bulky and difficult to clean
Solution Approach 1:
The voluminous spacer fabric is segmented into multiple thinner inserts stacked within the frame. Each insert maintains the air-permeable spacer structure for microclimate control, but the segmented approach allows them to be compressed for washing and reassembled to restore full volume and comfort properties.
Solution Approach 2:
The mattress structure transitions from a fixed bulky form to a dynamic configuration where spacer fabric inserts can be compressed during cleaning and expanded during use. The elastic frame accommodates this volume change while maintaining structural integrity.
3Ease of operation
If single piece spacer fabric is used for high comfort, then pressure distribution is improved, but the entire mattress must be cleaned together reducing cleaning efficiency
Solution Approach 1:
The single piece spacer fabric is divided into multiple smaller inserts that can be washed simultaneously in a washing machine. When reassembled in the frame, these inserts collectively provide the same pressure distribution function as a single large piece, while enabling efficient mechanical cleaning of all inserts at once.
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 modular design allows for simple, cost-effective cleaning of the mattress, maintaining hygiene and comfort by ensuring the spacer textiles can be washed in standard machines without compromising stability or comfort.
Implementation Method 1
the at least two elastic spacer textiles, in particular spacer fabrics, are arranged in an elastic frame... the at least two spacer textiles ensure a high level of lying comfort, since they ensure good pressure relief due to their good pressure distribution and point elasticity
Implementation Method 2
a correspondingly good microclimate due to their air and vapor permeability

AI summary
A mattress (1) has a frame (2) which is formed from an elastic material and bounds an interior (3) laterally. The interior (3) contains at least two elastic spacer textiles (4 to 15), which can each be released from the frame (2) and from one another. The mattress (1) is very comfortable to lie on, and the modular construction means that it can be cleaned in a conventional washing machine.
