Bedding
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bedding materials often contain synthetic fibers or animal hair, making them unsuitable for allergy sufferers and lacking in temperature-regulating properties, which can affect the sleeping climate.
Innovation Solution
A mixed fiber fleece composed of linen fibers and regenerated cellulose fibers equipped with phase change material (PCM) is used, excluding synthetic fibers and animal hair, providing natural, bacteriologically safe, and climate-controlled bedding.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If bedding fillings are made from synthetic fibers or animal hair, then they provide good insulation and comfort, but they are unsuitable for allergy sufferers and can cause allergic reactions
Solution Approach 1:
The patent removes harmful synthetic fibers and animal hair from the bedding filling composition entirely, extracting only the beneficial natural plant fibers (cotton, linen, hemp) that provide comfort without triggering allergies. This extraction principle directly resolves the contradiction by eliminating the harmful components while preserving the useful ones.
Solution Approach 2:
The invention creates a composite bedding filling made from multiple natural plant fibers (cotton, linen, hemp) combined in specific proportions. This composite approach allows the material to provide insulation and comfort properties while remaining hypoallergenic, as all components are natural plant-based materials that do not trigger allergic reactions.
2Adaptability or versatility
If bedding fillings are made from pure natural fibers, then they are suitable for allergy sufferers, but they lack temperature-regulating properties and cannot maintain optimal sleeping climate
Solution Approach 1:
The patent assigns different functional qualities to different fiber components within the composite filling. Cotton provides softness and moisture absorption, linen provides breathability and temperature regulation, while hemp adds structural integrity and additional temperature control. Each fiber type contributes its specific local quality to the overall system, achieving comprehensive temperature regulation while maintaining allergy safety.
3Stability of the object's composition
If bedding fillings use natural plant fibers only, then they are hypoallergenic, but they lack sustained bulking power and climate control properties
Solution Approach 1:
The composite bedding filling is designed to perform multiple functions simultaneously: cotton provides moisture management and softness, linen delivers breathability and temperature regulation, while hemp contributes durability and structural stability. This multi-functional composite material achieves sustained bulking power and climate control properties while maintaining 100% natural plant-based composition without introducing synthetic or animal components.
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 solution creates a positive sleeping climate with excellent temperature regulation and moisture management, ensuring optimal comfort and safety for allergy sufferers by using natural plant materials and PCM for heat storage and release.
Implementation Method 1
a regenerated cellulose fiber, which has its origin in wood, such as that of the eucalyptus tree... the regenerated cellulose is the warming part of the mixed fiber fleece, which is additionally equipped with a phase change material, English: phase change material - PCM material, which is in a solid state of aggregation in the cold state and liquefies in a heated state, whereby it absorbs heat, which it releases again when the outside temperature gets colder and when it transitions to the solid state
Implementation Method 2
The linen fiber is one of the oldest plants cultivated by humans and can absorb up to 35% of its own weight in moisture without feeling damp and releasing this moisture back into the ambient air very quickly

AI summary
Bedding, including duvets, mattress pads and pillows, is provided, consisting of a cover and a mixed-fiber fleece as bedding filling, which contains no synthetic fibers and is also free of any kind of animal hair and is therefore suitable for allergy sufferers and creates a positive sleeping climate, which is achieved by the fact that the mixed-fiber fleece consists of at least linen fibers and regenerated cellulose fibers equipped with phase change material (PZM material).
