Backpack Folding Chair With Hidden Straps and Integrated Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional folding chairs are cumbersome to carry, especially when used outdoors, as they require carrying both the chair and additional items like beach accessories or picnic supplies, without a practical solution for storage and transport.
Innovation Solution
A portable backpack chair with a foldable frame, adjustable armrests, and detachable shoulder straps, featuring integrated storage compartments that allow the straps to be hidden when in use, enabling easy transport and storage of additional items.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a conventional folding chair is used outdoors, then the chair can provide seating, but it becomes cumbersome to carry along with additional items like beach accessories or picnic supplies
Solution Approach 1:
The patent combines the chair structure with integrated storage compartments (pockets and cargo area) directly attached to the chair frame. This merging of seating function and storage function into a single unit eliminates the need to carry separate bags or containers for beach accessories and picnic supplies, directly resolving the contradiction between ease of carrying and quantity of items to carry.
2Ease of operation
If a backpack type chair is designed to be wearable, then carrying becomes easier, but the straps may interfere with the chair's stability or comfort when set up for use
Solution Approach 1:
The patent designs the shoulder straps as detachable components that can be removed from the chair structure. When the chair is set up for use, the straps can be detached or stowed away, preventing them from interfering with the chair's stability or comfort. This extraction of the carrying function from the seating function resolves the contradiction between ease of carrying and reliability when in use.
3Quantity of substance
If storage compartments are added to the chair, then additional items can be carried, but the chair's structure becomes more complex
Solution Approach 1:
The patent implements storage compartments that are nested within or attached to the existing chair frame structure. The pockets are positioned along the backrest and sides, utilizing the chair's vertical space, while the cargo area is integrated into the base structure. This nesting approach provides substantial storage capacity without significantly increasing the overall structural complexity or footprint of the chair.
4Volume of moving object
If the chair is designed to fold compactly, then it becomes more portable, but the folding mechanism becomes more complex
Solution Approach 1:
The patent employs a dynamic folding mechanism with multiple pivot points that allow the chair to collapse into a compact configuration. The seat, backrest, and legs are connected through hinges that enable smooth transitions between expanded and folded states. This dynamic design achieves compact folded dimensions while maintaining relatively simple construction through the use of standardized hinge components and straightforward geometric folding patterns.

AI summary
A backpack type folding chair is provided and includes a chair frame including a seat frame, a back frame, a front leg frame, and a back leg frame. At least one support panel to support a user is coupled about the back frame and the seat frame. A first storage receptacle is coupled to a rear face of a backrest portion of the at least one support panel that is coupled to the back frame. In addition, a second storage receptacle is defined between the first storage receptacle and the backrest portion. A pair of detachable shoulder straps are provided with each strap includes a first end that is attached along the rear face of the backrest portion and a second end that includes a first fastener that is configured to mate with a coupling member that is attached to the at least one support panel proximate the cross member for attaching the second end of the shoulder strap to the chair and permit carrying of the chair in a folded position. The pair of shoulder straps can be stored in the second storage receptacle when the chair is in an in-use position.
