Solution Overview

Problem

Conventional inflatable beds with interconnected mattresses lack the ability to provide different levels of softness at various areas, which can compromise user comfort.

Innovation Solution

An inflatable bed design featuring a mattress assembly with multiple air chambers that are not in fluid communication, allowing for individual inflation by an electric air pump unit, enabling varying air pressures across the bed to enhance comfort.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If mattresses are interconnected and inflated simultaneously by an electric air pump, then the structure is simple and easy to manufacture, but all areas have the same softness which reduces user comfort

Engineering Contradiction:
Improveease of manufactureVSAvoidadaptability
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The mattress is divided into multiple independent air chambers that are not in fluid communication with each other. Each chamber can be individually inflated or deflated by the electric air pump through separate air conduits, allowing different softness levels in different areas while maintaining a relatively simple overall structure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system transitions from a static, uniformly inflated mattress to a dynamic system where the air pump can selectively adjust the pressure in each air chamber independently. This allows the mattress to adapt its softness characteristics to match user preferences and body positioning requirements.

Inventive Principle:
Principle #15Dynamics

2Adaptability or versatility

If mattresses are divided into multiple independent air chambers for individual inflation, then different softness levels can be provided at different areas, but the device complexity increases

Engineering Contradiction:
ImproveadaptabilityVSAvoiddevice complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

A single electric air pump is designed to perform multiple functions: it can inflate and deflate all air chambers individually through a system of separate air conduits and valves. This multi-functional design achieves the adaptability of multiple independent chambers while avoiding the need for multiple separate pumps, thereby limiting the increase in device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Applied Scientific Principles

AI summary

An inflatable bed includes a bedstead assembly, a mattress assembly, and an electrical air pump unit. The mattress assembly is disposed on and above the bedstead assembly, and includes a top sheet, a bottom sheet disposed under the top sheet, and a plurality of surrounding sheets interconnecting the top and bottom sheets to form a plurality of air chambers, which are not in fluid communication with each other. Each of the air chambers is defined among the top sheet, the bottom sheet, and a respective one of the surrounding sheets. The electrical air pump unit is disposed on the bedstead assembly, and is operable to inflate the air chambers individually so that air pressures in the air chambers may be different.
