Multi-layer mattress core, and mattress
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mattresses do not offer a versatile and economical means to adapt to different sleeping habits and temperature preferences by altering the firmness and sleeping climate without requiring structural changes.
Innovation Solution
A mattress core with non-parallel dividing lines between layers of varying thickness and material, allowing for different sinking depths and climates by simple rotation, optionally with recesses and additional layers like barrel pocket springs, and a cover indicating the dividing line.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the mattress core uses layers of different materials with parallel dividing lines, then the structure is simple and easy to manufacture, but the adaptability to different sleeping habits and temperature preferences is limited
Solution Approach 1:
The patent applies asymmetry by making the dividing line between layers non-parallel to the longitudinal and transverse sides of the mattress core. This creates varying layer thicknesses across different regions (head end, foot end, longitudinal sides), allowing different body areas to experience different firmness levels and sinking depths, thereby adapting to different sleeping habits without requiring multiple separate mattresses
Solution Approach 2:
The patent implements local quality by creating region-specific layer configurations where the upper and lower layers have different thicknesses in different areas (head end vs. foot end, longitudinal sides). This allows localized adaptation to different body areas' support needs while maintaining a single integrated mattress structure
2Adaptability or versatility
If the mattress core uses layers of different materials with non-parallel dividing lines, then the adaptability to different sleeping preferences is improved, but the manufacturing complexity increases
Solution Approach 1:
The asymmetric dividing line design allows a single mattress core to provide different sleeping climates by rotating the mattress. When the head end is at one position versus the other, different layer configurations are presented to the sleeper, enabling temperature preference adaptation without manufacturing multiple specialized mattresses
3Adaptability or versatility
If additional processing is applied to create recesses in the material, then the firmness variation is enhanced, but the manufacturing cost increases
Solution Approach 1:
The patent creates localized firmness variations through non-parallel dividing lines that produce different upper and lower layer thicknesses in specific regions. This geometric approach to firmness adjustment avoids the need for additional processing steps like cutting recesses or channels, thereby maintaining ease of manufacture while achieving firmness variation

AI summary
In a mattress core that is delimited by the following sides: a top and a bottom side, two opposing end sides, of which one end side forms a head end of the mattress core and the other end side forms a foot end of the mattress core, as well as two opposing long sides, wherein a first, upper layer of the mattress core consists of a different material than a second, lower layer of the mattress core, and wherein a dividing line runs between these two layers, it is proposed that the dividing line between two layers located one above the other runs at different distances from the top and bottom sides, such that the upper of these two layers has a different thickness in a shoulder area that is closer to the head end than to the foot end than in a leg area that is closer to the foot end than to the head end of the mattress core. Furthermore, the invention relates to a mattress with the proposed mattress core.
