Inflatable Bed with Inner Support Structure to Reduce Mattress Shaking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Inflatable beds have a hard surface due to expanded air, which compromises comfort, and adding a mattress structure can lead to instability and shaking.
Innovation Solution
The inflatable bed design includes an inner support portion and outer support part with a mattress body featuring a comfort layer, fixing layers, and a sponge layer, along with a second surrounding frame, which enhances structural strength and stability by supporting the mattress body and preventing shaking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a mattress structure is provided on the surface of the inflatable bed to improve comfort, then comfort is improved, but the inflatable bed becomes prone to shake and stability deteriorates
Solution Approach 1:
The bed body is divided into an inner support portion and an outer support part, with the inner support portion further divided into multiple support columns. This segmentation provides multiple support points for the mattress body, distributing the load and preventing shaking while maintaining comfort.
Solution Approach 2:
The inner support portion is nested within the outer support part, with support columns arranged inside the inflatable cavity. This nested structure allows the inner support columns to work together with the outer support frame, providing combined support that stabilizes the mattress body without compromising comfort.
2Device complexity
If the bed body is made of fused waterproof fabric to maintain simplicity, then device complexity is reduced, but the surface becomes hard and comfort deteriorates
Solution Approach 1:
The waterproof fabric is applied selectively only to the outer support part that contacts the ground, while the inner support portion and mattress body use different materials. This localized application maintains the simplicity and waterproofing where needed while allowing comfort-focused materials in other areas.
Solution Approach 2:
The bed combines multiple materials: waterproof fabric for the outer support part, sponge material for the mattress body, and potentially breathable fabrics for the inner support portion. This composite material approach maintains structural simplicity while improving comfort through material diversity.
3Strength
If the inner support portion divides the inflatable cavity into middle and periphery cavities to improve structure strength, then structure strength is improved, but device complexity increases
Solution Approach 1:
The inflatable cavity is segmented into a middle cavity and a periphery cavity by the inner support columns. This segmentation reinforces the overall structure by creating multiple pressure zones that support each other, improving structure strength while using a relatively simple division method.
Solution Approach 2:
The inner support columns serve multiple functions: they divide the cavity to improve structure strength, provide direct support points for the mattress body, and maintain the inflatable structure's rigidity. This multi-functionality achieves structure strength enhancement without proportionally increasing complexity.
