Elastic Mattress Structure With Edge Support for Safe Bed Exit
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional spring mattresses with fixed elasticity pose a risk of users falling off the bed when getting up, as they lack sufficient flexibility and support to facilitate safe exit.
Innovation Solution
The mattress structure features an elastic main body with two elongated extensions and support areas made of densely wound second plastic wires, combined with irregularly wound first plastic wires and gaps for air circulation, providing varying elasticity and rigidity to assist users in safely exiting the bed by distributing body pressure effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the mattress uses fixed elasticity springs, then the mattress structure is simple and stable, but the user may fall off when getting up due to insufficient flexibility
Solution Approach 1:
The patent applies the dynamics principle by transitioning from fixed elasticity springs to plastic wires with melted connection portions that can deform and adapt to user movements. The plastic wires change their structural state dynamically - remaining rigid for support during normal use but allowing controlled deformation when users need to get up, thus providing both reliability and adaptability
Solution Approach 2:
The patent implements parameter changes by modifying the physical state of the connection portions of plastic wires through melting. This creates gaps that change the elasticity parameter of the mattress structure, allowing it to provide firm support when needed while enabling greater flexibility and deformation capability when users need to exit the bed safely
2Strength
If the mattress uses densely wound plastic wires in support areas, then the rigidity and support are improved, but the air circulation may be reduced
Solution Approach 1:
The patent applies local quality by creating different wire densities in different areas of the mattress. Support areas have densely wound second plastic wires to provide enhanced rigidity and support strength, while other areas maintain lower density to preserve air circulation. This localized differentiation allows the mattress to simultaneously achieve both support strength and air circulation requirements
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 user safety by reducing the likelihood of falling off the bed through controlled deformation and air circulation, ensuring a stable and secure exit mechanism.
Implementation Method 1
air flows through the plural gaps of the elastic mattress to cause air circulation in the mattress structure
Implementation Method 2
an elasticity of each support area is less than that of the main body... the one of the two elongated extensions is supported by the at least one support area to avoid great a deformation

AI summary
A mattress structure contains: an elastic mattress. The elastic mattress includes a main body, two elongated extensions extending along two peripheral sides of the main body, and an outer segment formed on one end thereof to correspond to user's feet. The elastic mattress is made of plural first plastic wires which are solid and are irregularly winded together, a connection portion of at least two of the plural first plastic wires is melted, and a disconnection portion of the at least two of the plural first plastic wires includes plural gaps formed therein. The elastic mattress also includes two support areas arranged below the two elongated extensions, and each support areas has plural second plastic wires winded therein, wherein a density of the plural second plastic wires is greater than those of the other positions of the elastic mattress besides the two support areas.
