Mattress Bottom Layer Slit for Core Access

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing mattress systems lack easy access to internal components, making maintenance and servicing difficult without cutting open layers, which complicates the adjustment and maintenance of mattress firmness and support structures.

Innovation Solution

A mattress system design featuring a bottom layer with a slit that separates into two portions, allowing access to the mattress core and other components within a rail structure, enabling the core to be inserted and serviced without cutting, and incorporating a pump system for adjustable air chambers and foam layers for customizable support.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the mattress core is enclosed in a complete bottom layer, then the structural integrity is improved, but the accessibility to internal components deteriorates

Engineering Contradiction:

Improvestructural integrityVSAvoidaccessibility to internal components

Core Design Contradiction:

StrengthVSEase of operation

Solution Approach 1:

The bottom layer is segmented into two portions separated by a slit, allowing the layers to be pulled apart to access the mattress core while maintaining structural integrity when closed. This segmentation enables both protection and accessibility without compromising overall strength.

Inventive Principle:

Principle #1Segmentation

2Ease of manufacture

If the bottom layer is made as a single intact piece, then the manufacturing simplicity is improved, but the ease of maintenance deteriorates

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidease of maintenance

Core Design Contradiction:

Ease of manufactureVSEase of repair

Solution Approach 1:

The bottom layer is designed with a slit dividing it into two portions that can be separated. This maintains relative manufacturing simplicity while enabling easy maintenance, as the mattress core becomes accessible by pulling apart the pre-segmented layers rather than requiring cutting during maintenance.

Inventive Principle:

Principle #1Segmentation

3Stability of the object's composition

If the mattress core is fully enclosed, then the support structure stability is improved, but the adjustability deteriorates

Engineering Contradiction:

Improvesupport structure stabilityVSAvoidadjustability

Core Design Contradiction:

Stability of the object's compositionVSAdaptability or versatility

Solution Approach 1:

The bottom layer transitions from a static enclosed structure to a dynamic accessible structure through the slit mechanism. The layers can be pulled apart to adjust or maintain the mattress core, then reconnected to restore stability, enabling both stability and adjustability.

Inventive Principle:

Principle #15Dynamics
