Combined foldable chair and storage backpack
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current foldable chair designs with storage containers are uncomfortable to carry due to unbalanced weight distribution and lack protection for the storage area when folded, making them vulnerable to damage.
Innovation Solution
A combined foldable chair and backpack apparatus with a frame assembly, fabric, and storage compartment that allows for a balanced weight distribution and protection of the storage area when folded, featuring a hinge assembly and shoulder straps for comfortable carrying.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the chair is designed with a storage compartment, then the functionality is improved, but the weight distribution becomes unbalanced and comfort deteriorates
Solution Approach 1:
The patent combines the chair and backpack into a single integrated structure where the chair frame itself forms the backpack framework. The storage compartment is merged into the chair structure, eliminating separate components and achieving balanced weight distribution through unified design.
Solution Approach 2:
The patent applies different structural qualities to different parts of the chair. The seat and backrest areas are designed with padding and fabric for comfort, while the frame structure provides rigidity for support. The storage compartment is positioned and structured to balance the overall weight distribution.
2Adaptability or versatility
If the chair is designed with a storage compartment, then the functionality is improved, but the storage area becomes vulnerable to damage
Solution Approach 1:
The storage compartment is nested within the chair frame structure, with the compartment positioned inside the protective enclosure formed by the chair's legs and crossbars. This nesting arrangement provides inherent protection to stored items.
Solution Approach 2:
The patent incorporates padding and protective fabric coverings around the storage compartment and exposed frame areas before damage can occur. The fabric material serves as a protective layer that cushions and safeguards the structural components.
3Weight of moving object
If the chair is made foldable, then the portability is improved, but the structural complexity increases
Solution Approach 1:
The chair is divided into segmented components connected by hinges, allowing the frame to fold into a compact configuration. The seat, backrest, and legs are separable sections that can be folded and collapsed independently, reducing overall size for portability.
Solution Approach 2:
The patent employs dynamic hinge joints that allow the chair structure to transition between rigid (when assembled) and flexible (when folding) states. The hinges enable controlled movement and transformation of the frame geometry without requiring complex disassembly procedures.

AI summary
A combined foldable chair and backpack that is movable between and open configuration for a user to sit thereon, and a folded configuration for a user to carry, is provided. The combined foldable chair and backpack includes a frame assembly, a fabric coupled to the frame assembly, a shoulder strap coupled to either the frame assembly or the fabric, and a storage compartment coupled to either the frame assembly or the fabric. The frame assembly includes a seat frame, a back frame pivotally coupled to the seat frame via a hinge assembly, a front leg pivotally coupled to the seat frame by a hinge, and a rear leg pivotally coupled to the hinge assembly by a hinge.
