Double-Layer Inflatable Bed Structure With Recessed Cover Retention

Solution Overview

Problem

Double-layer inflatable beds require complex manufacturing processes, high production costs, and often experience issues with bed covers slipping off due to the lack of a special structure for secure placement.

Innovation Solution

A double-layer inflatable bed design featuring a top piece, middle piece with an oblique ring, and bottom piece, along with tensioning structures and oblique ring tapes, which optimize the splicing process, reduce production costs, and create a recessed connection for easy bed cover placement.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If an upper inflatable bed and a lower inflatable bed are spliced together using connecting members, then a double-layer inflatable bed is formed, but the manufacturing process becomes complicated and production cost increases

Engineering Contradiction:

Improvestability of double-layer structureVSAvoidmanufacturing process complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the upper and lower inflatable beds into a single integrated structure where the lateral piece forms a continuous wall between the two air chambers. This eliminates the need for separate connecting members and simplifies the manufacturing process while maintaining the stability of the double-layer configuration.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The lateral piece serves multiple functions: it forms the boundary between the upper and lower air chambers, provides structural support, and eliminates the need for separate connecting members. This multi-functional design reduces the number of components and simplifies the overall manufacturing process.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Reliability

3Ease of manufacture

If traditional inflatable bed structure is used, then manufacturing is simpler, but bed cover slips off causing inconvenience

Engineering Contradiction:

Improvemanufacturing simplicityVSAvoidbed cover retention

Core Design Contradiction:

Ease of manufactureVSEase of operation

Solution Approach 1:

The patent applies a specific structural feature (the recessed connection formed by the lateral piece) at the location where the bed cover needs to be retained. This localized structural modification provides bed cover retention without complicating the overall manufacturing process.

Inventive Principle:

Principle #3Local quality

AI summary

An inflatable bed is provided, comprising: a top piece, a middle piece having a middle master piece and an oblique ring piece having an inner edge connected to the middle master piece, and a bottom piece; a first lateral piece connected to the top piece and to an outer edge of the oblique ring piece; and a second lateral piece connected to the middle piece and to the bottom piece. A first air chamber is defined by the top piece, the middle piece, and the first lateral piece. A second air chamber is defined by the middle piece, the bottom piece, and the second lateral piece.
