Transformable chair and backpack assembly and method of use
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing transportable and transformable floor chairs are cumbersome, with bulky designs, difficult deployment, and lack comfort and secure storage, as well as a unified system that integrates both chair and backpack functionality.
Innovation Solution
A transformable chair and backpack assembly where the seat has straps on its underside for carrying, a backpack with a zippered enclosure affixed to the rear, and a hinged connection allowing the chair to be sandwiched between the straps and backpack for easy transport, while also being deployable for sitting, with optional features like loops, handles, and internal frames for comfort and structural support.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Weight of moving object
If existing floor chairs are made transportable, then mobility is improved, but they become bulky and cumbersome
Solution Approach 1:
The seat bottom is nested within the backpack structure, with the backpack serving as the outer shell and the seat bottom fitting inside it. This nesting arrangement allows the chair components to be compactly stored within the backpack volume, eliminating bulkiness while maintaining transportability.
Solution Approach 2:
The invention merges the backpack and chair into a single integrated assembly. The backpack is not merely a separate carrying bag but is structurally combined with the seat bottom and backrest through straps and framing, creating a unified object that functions as both backpack and chair.
2Adaptability or versatility
If existing floor chairs are made transformable, then functionality is improved, but deployment becomes difficult
Solution Approach 1:
The chair structure employs dynamic, movable connections rather than fixed rigid joints. The seat bottom is connected to the backrest through a hinge assembly that allows easy rotation and positioning, enabling simple transformation between compact and deployed states without complex mechanisms.
Solution Approach 2:
The chair is divided into segmented components (backpack shell, seat bottom, backrest, legs) that can be independently positioned and assembled. This segmentation allows each component to be deployed separately through simple actions, making the overall transformation process easy and intuitive.
3Adaptability or versatility
If existing floor chairs include storage, then functionality is improved, but comfort and secure storage are lacking
Solution Approach 1:
The backpack serves multiple functions simultaneously: it acts as the outer protective shell, provides structured storage compartments with zippers, offers structural support through its frame, and serves as the base for assembling the chair. This multi-functionality eliminates the need for separate storage components while ensuring secure storage through the backpack's inherent zippered compartments.

AI summary
A transformable floor chair has a seat and a back. The seat has straps for carrying the chair when transformed into a transportation configuration. The straps are located on the underside of the seat when in a deployed configuration. A backpack including zippered enclosure is affixed to the rear of the floor chair back. The backpack remains usable and functional when in either the transportation configuration or the deployed configuration. When transformed into the transportation configuration, the upper portion of the seat is secured to the front face of the chair back, thereby sandwiching the chair between the straps and the backpack.
