Solution Overview
Problem
Existing mattress inserts fail to provide uniform support for individuals of varying weights and are unable to adapt to changes in body weight and shape over time, leading to reduced comfort and potential health issues due to their limited load range and structural fatigue.
Innovation Solution
A mattress insert featuring supporting blocks of varying heights made of foam material, where taller blocks provide initial support for lighter loads and shorter blocks engage as loads increase, allowing for adjustable spacing and compression to distribute weight evenly across the surface, with a multilayer configuration of different densities to enhance support and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If foam blocks of uniform height are used throughout the mattress, then manufacturing is simplified and structural consistency is maintained, but the mattress cannot provide differentiated support for different body regions or adapt to varying user weights
Solution Approach 1:
The mattress is divided into multiple independent foam blocks arranged in rows and columns, with each block capable of independent compression. This segmentation allows different blocks to have different heights and firmness levels, enabling region-specific support while maintaining overall mattress functionality.
Solution Approach 2:
Different regions of the mattress are equipped with foam blocks having locally optimized properties - taller blocks in head and foot regions, shorter blocks in the middle region, with varying heights and densities tailored to specific body regions (shoulders, waist, legs) to provide appropriate support and comfort zones.
2Adaptability or versatility
If springs are used to provide load support, then support for varying weights is improved, but the load support surface has large unsupported areas between springs and spacing cannot be arbitrarily small
Solution Approach 1:
Instead of using traditional spring structures, the invention uses foam blocks that replicate the load-supporting function of springs. These foam blocks can be arranged with arbitrarily small spacings, eliminating the large unsupported areas between spring elements while maintaining the ability to support varying loads through foam compression.
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 enables the mattress insert to provide differentiated reaction forces based on load, ensuring consistent support for users of different weights and adapting to body shape changes, thereby improving comfort and reducing the risk of health issues associated with structural fatigue.
Implementation Method 1
supporting blocks (10, 12, 14) made of a foam material... When the mattress insert according to the invention is subjected to lower loads, the weight of the body loading the mattress is supported by the first supporting blocks (10) having larger height. In case of higher loads the higher supporting blocks are compressed to an extent that the second supporting blocks (12, 14) also come into play in supporting the load.
