Backpack with deployable chair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing portable, lightweight chairs are difficult to integrate into a backpack due to the need for repeated assembly and disassembly, which complicates the design, increases costs, and reduces the chair's useful life.
Innovation Solution
A dual-configuration backpack with a low-profile frame and articulating seat integrated into a fabric cover, featuring a tubular frame with U-shaped portions and pivotable foam cushion that can be easily deployed and stowed, allowing for comfortable seating and unobtrusive wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If prior art chairs are integrated into a backpack, then portable seating is achieved, but repeated assembly and disassembly is required which complicates design and reduces useful life
Solution Approach 1:
The chair frame is permanently integrated into the backpack structure, merging two previously separate functions (backpack carrying and chair seating) into a single unified device. The tubular frame forms both the backpack support structure and the chair support structure, eliminating the need for separate assembly operations.
Solution Approach 2:
The tubular frame serves multiple functions simultaneously: it provides structural support for the backpack when worn, forms the chair structure when deployed, and supports both the seat cushion and backrest cushion. This multi-functionality eliminates the need for separate assembly steps.
2Adaptability or versatility
If prior art chairs are integrated into a backpack, then portable seating is achieved, but manufacturing costs increase due to complex assembly
Solution Approach 1:
The chair frame is permanently integrated into the backpack structure during manufacturing, merging two previously separate functions (backpack carrying and chair seating) into a single unified device. The tubular frame forms both the backpack support structure and the chair support structure, eliminating the need for separate assembly operations.
3Adaptability or versatility
If a deployable seat is added to the backpack, then seating functionality is improved, but the backpack comfort and load support may be affected
Solution Approach 1:
The seat cushion is designed to be pivotable between a deployed position (providing seating functionality) and a retracted position (maintaining backpack comfort and load support). This dynamic positioning allows the system to adapt between two functional states without compromising either function.
Solution Approach 2:
The seat cushion is positioned locally at the bottom of the backpack and can be independently deployed or retracted without affecting the overall backpack structure or the backrest cushion positioning. This localized functionality preserves the integrity of the backpack's load-bearing characteristics.

AI summary
A dual-configuration chair and backpack having at least one storage compartment with a back panel and a bottom panel held in rigid orientation to each other at a predetermined angle by an integral tubular frame having a two generally U-shaped frame portions fixed at the selected angle. A deployable seat is rotatably affixed to a lower edge of the back panel and includes a flat foam cushion formed at an angle complementary to the angle between the back and bottom panels of the backpack. When used as a seat the flat serves as a cushion under the buttocks of the user. When used as a backpack the flat is rotated up to the back panel such that the complementary angles position the cushion for proper lumbar and back support of the backpack load.
