Two-Chamber Inflatable Ottoman for Adjustable Support and Portability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ottomans lack portability and flexibility in providing varying levels of support and height, limiting their usability as both footrests and seating options.
Innovation Solution
A lightweight ottoman constructed from an inflatable PVC bladder with two interconnected chambers, adjustable carrying straps, and PVC side ribs, allowing for adjustable firmness and height by inflating one or both chambers, and featuring a pocket for storing the carrying strap.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional ottomans are made with fixed structure, then they provide stable support, but they lack portability and flexibility in providing varying levels of support
Solution Approach 1:
The ottoman is divided into two separate inflatable chambers that can be independently inflated or deflated. This segmentation allows the user to adjust the firmness and height by controlling which chamber is inflated, providing varying levels of support while maintaining a lightweight, portable structure when deflated
Solution Approach 2:
The ottoman uses inflatable chambers that can dynamically change volume and firmness based on air pressure. The chambers transition from a deflated state (for portability) to an inflated state (for support), enabling the ottoman to adapt between transport and use modes while providing adjustable support levels
2Adaptability or versatility
If conventional ottomans are made as single-chamber structures, then they are simple in construction, but they cannot provide varying levels of support or function as both footrest and seating
Solution Approach 1:
The ottoman employs two separate chambers (first chamber and second chamber) that can be independently controlled. By inflating one chamber while keeping the other deflated, the ottoman can function as a footrest; by inflating both chambers, it provides full seating support, thus achieving multiple functions without complex mechanisms
Solution Approach 2:
The dual-chamber design enables the ottoman to serve multiple functions: it can be used as a footrest (one chamber inflated), as an ottoman (one chamber inflated with varied support), or as a seat (both chambers inflated). This multi-functionality is achieved through a relatively simple inflatable structure rather than multiple separate devices

AI summary
An inflatable two-chambered rectangular ottoman with attached shoulder strap and pocket is an inflatable bladder constructed from polyvinyl-chloride material with heat sealing for assembly. The two chambers allow for flexibility in firmness of support and height either as a footrest with one chamber inflated or as an ottoman with varying levels of support dependent upon which side the ottoman rests on the floor. Additional support is provided in the ottoman by additional ribbing on each side also made from polyvinyl-chloride material. The ottoman has a velour surface on five sides. The sixth side is two-layered non-velour polyvinyl-chloride material with an opening on one of the shorter sides to form a pocket. Attached to the inner layer of the non-velour PVC side are the two ends of the attached adjustable carrying strap. The strap can be placed inside the pocket when in use on the floor.
