Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional mattresses fail to provide adequate comfort and support for pregnant women as the abdomen expands, as they lack dynamic adjustment capabilities to accommodate changing sizes and positions over time.

Innovation Solution

An inflatable bed system with a primary inflatable section featuring a centrally located abdomen cavity, a secondary inflatable section within the cavity, and at least one tertiary inflatable section, allowing for adjustable firmness, diameter, and leg elevation through a valve and pump system controlled by a remote control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a static cavity mattress is used, then the structure is simple, but it cannot accommodate changing abdomen size and orientation over time

Engineering Contradiction:

Improveaccommodation of changing abdomen size and orientationVSAvoidmattress structure complexity

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The mattress is divided into multiple independently inflatable chambers (first, second, third, and fourth chambers) that can be inflated or deflated separately. This segmentation allows the mattress to adapt to changing abdominal dimensions by adjusting specific chambers without affecting the entire structure, resolving the contradiction between adaptability and structural simplicity.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The mattress transitions from a static structure to a dynamic one through the inclusion of inflatable chambers that can change volume. The chambers can be inflated to accommodate an expanding abdomen and deflated as the pregnancy progresses, providing continuous adaptability throughout the pregnancy period while maintaining a relatively simple base structure.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If a single-chamber inflatable mattress is used, then the structure is simple, but it cannot provide differentiated support for different body regions

Engineering Contradiction:

Improvedifferentiated support for different body regionsVSAvoidnumber of inflatable chambers

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

Each inflatable chamber is designed to provide specific local support: the first chamber supports the abdomen, the second chamber provides peripheral support, the third chamber supports the lower back, and the fourth chamber supports the legs. This local differentiation allows each region to be optimized independently, providing targeted support without requiring excessive complexity in the overall structure.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The mattress is segmented into four distinct inflatable chambers, each capable of independent volume adjustment. This segmentation enables differentiated support for different body regions while maintaining a modular structure that is not overly complex, as each chamber follows a similar inflatable design pattern.

Inventive Principle:

Principle #1Segmentation

3Adaptability or versatility

If multiple inflatable chambers are added, then adaptability and support are improved, but the device complexity increases

Engineering Contradiction:

Improvedynamic adjustment capabilityVSAvoidnumber of control valves and chambers

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single pump is designed to inflate all four chambers through a system of one-way valves, making the pump a universal component that serves multiple functions. This multi-functionality approach allows dynamic adjustment of all chambers without requiring four separate pumps, thereby reducing overall device complexity while maintaining high adaptability.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

One-way valves act as intermediaries between the single pump and the four inflatable chambers. These valves control the direction of air flow, allowing the pump to inflate any chamber while preventing air from flowing back to other chambers. This intermediary mechanism enables independent chamber adjustment with a single pump, resolving the contradiction between adaptability and complexity.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An inflatable bed system (1) includes a primary inflatable section (2) having a centrally located abdomen cavity shaped to allow a user's abdomen to be positioned therein. The system further includes a secondary inflatable section (3), which is independently inflatable and positioned inside the cavity. At least one tertiary inflatable section (15,22) is provided to allow further configuration of the bed. The bed may be inflated by a pump that is operatively connected with a valve which directs the movement of air into each of the inflatable sections under user selection.
