Collapsible Multi-Mode Chair Frame with Integrated Storage Bag
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor chair systems lack adaptability and multifunctionality, particularly in compact and ultralight forms that can serve various recreational needs such as seating, sun/rain protection, and storage, while being easy to transport and deploy.
Innovation Solution
An adaptive chair system with a collapsible frame that stows within a compact flexible multi-function bag (MFB), which can transform into different modes (e.g., full-sized chair, low-profile seat, sun canopy, and footrest) and includes various inserts (thermal insulation, inflatable core, fluid filter) for enhanced utility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a traditional outdoor chair is designed to provide multiple functions (seating, storage, sun/rain protection), then the adaptability and versatility improve, but the weight and device complexity increase
Solution Approach 1:
The patent implements a single chair structure that can perform multiple functions: seating, storage (via integrated bag), sun/rain protection (via canopy), and footrest support. The chair frame, seat, backrest, and various attachments work together to provide these diverse functions without requiring separate devices, thereby achieving versatility while controlling weight.
Solution Approach 2:
The patent combines multiple functional elements into a unified chair system: the seat integrates with a storage bag, the backrest connects to a canopy structure, and the frame incorporates armrests and footrest capabilities. This merging of functions into a single integrated structure reduces the total weight compared to carrying separate items for each function.
2Adaptability or versatility
If a traditional outdoor chair is designed to provide multiple functions (seating, storage, sun/rain protection), then the adaptability and versatility improve, but the device complexity increases
Solution Approach 1:
The patent divides the multifunctional chair into distinct modular components: a main chair frame, an integrated storage bag, a separate canopy structure, and attachable footrest elements. Each component can be independently assembled, adjusted, or removed, allowing the user to configure the chair for different functions without managing a single complex monolithic structure.
Solution Approach 2:
The chair incorporates adjustable and reconfigurable elements: the canopy can be deployed or stowed, the storage bag can be attached or detached, and the footrest can be positioned or removed. These dynamic features allow the structure to adapt to different functional requirements without permanent complex configurations.
3Weight of moving object
If an outdoor chair is designed to be compact and ultralight for easy transport, then the weight and volume decrease, but the adaptability and multifunctionality are limited
Solution Approach 1:
The patent implements a nested configuration where the storage bag is integrated within or attached to the chair seat, the canopy folds and stores within or alongside the chair structure, and various components can be collapsed or compressed into each other. This nesting allows multiple functional elements to be packed into a compact ultralight form for transport, yet deployed to provide full multifunctionality when needed.
4Strength
If a chair frame is designed to be strong and durable for outdoor use, then the strength and reliability improve, but the weight increases
Solution Approach 1:
The patent employs composite construction in the chair frame, combining materials with different properties to achieve high strength-to-weight ratio. The frame likely uses aluminum or composite tubes that provide structural strength and durability for outdoor use while remaining lightweight enough for portability, avoiding the need for heavier solid metal construction.

AI summary
Various systems and methods relate to an adaptive chair system having (i) a stowed mode in which members of the chair frame are compactly contained within a multi-function bag (MFB), and (ii) a deployed mode in which the multi-purpose chair is configured to transition between at least two seating modes. In an illustrative example, the chair may be provided with an adaptive frame which may be reconfigured to transition between the seating modes. For example, the chair may transition between any of a vertical/upright (chair) mode (e.g., FIG. 8B), a vertical/upright (chair) mode using trek pole handle segment(s) (e.g., FIG. 1C), a low-profile/recon (seat) mode (e.g., FIG. 2B), and a longitudinal/lounge mode (e.g., FIG. 2B). Various embodiments may advantageously provide an adaptive chair system in an ultralight form factor which may fulfill multiple functions including, by way of example and not limitation, seating, sun/rain canopy, footrest, or some combination thereof.
