Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing mattresses with multiple layers and spring filling lack structural firmness in the radial direction, leading to premature collapse under human body load, affecting their service life.
Innovation Solution
A high-elastic anti-deformation mattress design featuring a multi-layer structure with reinforcing nets and elastic insertion rods, springs embedded in tubular packaging cushions, and a grid-like reinforcing net system to distribute load evenly and prevent deformation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a large number of springs are filled in the mattresses as support, then the comfort is improved, but the structural firmness in radial direction deteriorates, causing the mattresses to collapse prematurely
Solution Approach 1:
The mattress is divided into multiple layers (first layer, second layer, third layer) with assembling chambers distributed throughout. Each chamber contains individual springs with connecting bases, creating a segmented support structure that maintains comfort while preventing radial collapse through distributed reinforcement.
Solution Approach 2:
The connecting bases are inserted into both the top ends and bottom ends of springs, with reinforcing nets connected among all connecting bases on the top portion and bottom portion. This nested arrangement of bases within spring ends and nets among bases creates multiple concentric reinforcement layers that prevent radial deformation.
2Ease of operation
If multiple layers of units are stacked to improve comfort, then the comfort is improved, but the anti-deformation ability deteriorates
Solution Approach 1:
The reinforcing nets are arranged in horizontal planes at the top and bottom portions of the second layer, creating reinforcement in the radial dimension perpendicular to the vertical stacking of layers. This dimensional approach prevents lateral collapse without interfering with the vertical comfort function of the layered structure.
Solution Approach 2:
The reinforcing nets are positioned specifically at the top and bottom portions of the second layer where connecting bases are located, providing localized reinforcement exactly where springs need support. This targeted approach maintains comfort in other areas while preventing deformation at critical support points.
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 design enhances the mattress's ability to uniformly distribute load, preventing localized deformation and extending its service life by uniformly stressing the upper and lower areas, while maintaining a horizontal surface and improving comfort.
Implementation Method 1
an elastic insertion rod is connected between each upper connecting base and the corresponding lower connecting base; the elastic insertion rods downwards wrap the springs from the top ends to the bottom ends
Implementation Method 2
each assembling chamber is filled with a spring; a top end of each spring is upwards close to a top portion of the corresponding assembling chamber, and a bottom end of each spring is downwards connected to a top surface of the third layer
Implementation Method 3
outer circular surfaces of the independent packaging cushions are tightly attached to the chamber surfaces of the assembling chambers; the springs wrapped with the elastic insertion rods are jointly embedded into the independent packaging cushions
