Solution Overview

Problem

Inflatable airbeds experience shape distortion and loss of structural stability when a user sits or lies on them, leading to discomfort due to increased internal pressure, and existing solutions either make the airbed heavy or cumbersome or increase production costs by using multiple chambers.

Innovation Solution

An internal support system comprising side support beams and an internal support wall that attaches to the top and bottom panels of the airbed, providing structural stability and preventing deformation by creating a visual impression of stacked horizontal chambers while maintaining lightweight construction.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If internal structures are added to prevent shape distortion, then structural stability is improved, but weight increases making the airbed heavy and cumbersome

Engineering Contradiction:

Improvestructural stabilityVSAvoidweight

Core Design Contradiction:

Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The airbed is divided into multiple sealed chambers that are stacked vertically, with each chamber contributing to the overall structural stability. The segmentation allows the airbed to maintain shape and resist distortion without requiring heavy external frames or supports, as each chamber acts as an independent structural unit that distributes loads evenly.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent uses flexible vinyl or plastic film to construct the chambers and internal support structures. These thin film walls provide sufficient structural integrity to prevent shape distortion while maintaining lightweight construction. The flexible nature of the material allows the chambers to deform slightly under load while maintaining overall structural stability.

Inventive Principle:

Principle #30Flexible shells and thin films

2Stability of the object's composition

If multiple horizontal chambers are stacked to prevent shearing forces, then structural stability is improved, but production cost increases and the airbed becomes more cumbersome

Engineering Contradiction:

Improvestructural stabilityVSAvoidproduction cost

Core Design Contradiction:

Stability of the object's compositionVSEase of manufacture

Solution Approach 1:

The patent combines multiple functions into a single integrated structure. The internal support walls serve dual purposes: they provide structural stability to prevent shape distortion and simultaneously create the separated chamber configuration needed to resist shearing forces. This merging eliminates the need for separate support structures and reduces production complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The internal support walls perform multiple functions: they provide structural reinforcement, create chamber separations, prevent shape distortion, and resist shearing forces. This multi-functionality reduces the overall number of components needed, simplifying manufacturing and reducing production costs while maintaining structural stability.

Inventive Principle:

Principle #6Universality (Multi-functionality)
