Solution Overview

Problem

Existing inflatable mattresses lack sufficient flexibility and comfort due to a single-layer top panel, limiting user experience.

Innovation Solution

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single-layer top panel is used in the inflatable mattress, then the device complexity is reduced and manufacturing is simpler, but the flexibility and comfort are insufficient

Engineering Contradiction:

Improvetop panel structureVSAvoidflexibility and comfort

Core Design Contradiction:

Device complexityVSEase of operation

Solution Approach 1:

The top panel is divided into multiple layers (first layer, second layer, third layer) that are joined together to form multiple chambers. This segmentation allows each layer to contribute to the overall flexibility and comfort while maintaining a relatively simple individual layer structure, thus resolving the contradiction between device complexity and comfort.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The multi-layer structure is arranged such that the first layer, second layer, and third layer are nested together with the second layer between the first and third layers. This nested arrangement creates multiple chambers that enhance flexibility and comfort without significantly increasing the overall footprint or complexity of the mattress structure.

Inventive Principle:

Principle #7Nested doll (Nesting)

2Ease of operation

If multiple layers are joined to form multi-chamber structure, then flexibility and comfort are improved, but the device complexity increases

Engineering Contradiction:

Improveflexibility and comfortVSAvoidmulti-layer multi-chamber structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The complex multi-chamber structure is achieved by segmenting the top panel into distinct layers that can be independently manufactured and then joined together. This segmentation makes the complex structure more manageable and easier to manufacture despite the increased number of components.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Multiple layers are merged together through joining operations to form the multi-chamber structure. The first layer, second layer, and third layer are combined to create the final comfortable surface, where the complexity is distributed across multiple simpler components that work together.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If the first layer and second layer are joined to form face-side chambers, then comfort performance is improved, but the manufacturing process becomes more complex

Engineering Contradiction:

Improvecomfort performanceVSAvoidjoining process

Core Design Contradiction:

Ease of operationVSEase of manufacture

Solution Approach 1:

The joining process is segmented into specific connection points between layers rather than requiring continuous bonding across the entire surface. This allows the layers to be joined at discrete locations to form chambers, simplifying the manufacturing process while maintaining comfort performance.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The joining of layers is applied locally at specific regions to form the face-side chambers, rather than uniformly across the entire top panel. This local quality approach allows for comfortable multi-chamber construction while reducing the overall complexity and time of the manufacturing process.

Inventive Principle:

Principle #3Local quality

AI summary

A multi-layer and multi-chamber inflatable mattress includes a mattress body enclosed by a top panel, a surrounding band and a bottom panel. The top panel includes a first layer and a second layer laid below the first layer. At least one of the first layer and the second layer is joined to the surrounding band, and the first layer is joined to the second layer to form a plurality of face-side chambers. The top panel is multi-layered with the multi layers formed a plurality of chambers, such chambers are in direct contact with human bodies when in use, which thus can improve comfort performance of the mattress, thereby improving sleep quality of users and experience of using.
