Multipurpose accessory bag for multi-mode portable collapsible chair
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing outdoor chair solutions lack versatility and compactness, failing to provide multifunctional utility in both stowed and deployed modes while maintaining a lightweight and compact form factor.
Innovation Solution
An adaptive chair system with a compact flexible multi-function bag (MFB) that stows the chair frame and transforms into various accessories, such as a sun/rain canopy, footrest, and thermal insulation, using a collapsible frame that can be deployed as a full-sized chair or a low-profile seat, and includes interchangeable inserts for different functions like a pillow or fluid filter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a traditional outdoor chair is designed to be sturdy and comfortable, then it provides good seating support, but it becomes heavy and difficult to transport
Solution Approach 1:
The chair is divided into separate modular components: a collapsible frame, a seat, and a multi-function bag that can be used independently or together. This segmentation allows users to carry only the necessary components, reducing overall transport weight while maintaining full seating functionality when assembled.
Solution Approach 2:
The chair frame employs collapsible legs with mechanical locking mechanisms that allow the structure to transition between a compact stored state and a deployed seating state. This dynamic design enables the chair to be lightweight and portable when collapsed, yet provide sturdy support when assembled.
2Weight of moving object
If outdoor gear is designed to be lightweight and compact, then it is easy to transport, but it lacks versatility and multifunctional utility
Solution Approach 1:
The multi-function bag is designed to perform multiple roles: it serves as a storage bag for the chair components, a standalone seat when the frame is collapsed, and a carrier for various outdoor gear. This universal design allows a single lightweight component to provide diverse functional utility across different outdoor scenarios.
Solution Approach 2:
The chair seat and backrest nest within the multi-function bag when not in use, creating a compact packaged configuration. This nesting arrangement allows the entire chair system to be stored in a small volume while maintaining full functionality when deployed, achieving both compactness and versatility.
3Volume of moving object
If a chair is designed to be compact for storage, then it is easy to transport, but it lacks the stability and comfort of a full-sized chair
Solution Approach 1:
The chair legs incorporate expandable sections with mechanical locking mechanisms that allow the structure to transition from a compact folded state to a fully extended stable state. When deployed, the legs lock into position to provide rigid support, ensuring chair stability while maintaining compact storage volume.
Solution Approach 2:
The chair frame is segmented into multiple collapsible leg sections that can be folded together for compact storage yet extended and locked for stable seating. This segmentation allows the chair to achieve both small storage volume and adequate stability through proper mechanical design of the expandable components.
4Adaptability or versatility
If outdoor equipment is designed with multiple separate functions, then each function can be optimized, but the overall system becomes complex and requires carrying multiple items
Solution Approach 1:
Multiple outdoor functions are merged into a single integrated system: the multi-function bag combines storage capabilities, seating functionality, and gear-carrying capacity. By merging these functions into one component rather than requiring separate items, the system reduces overall complexity while maintaining diverse functional capabilities.
Solution Approach 2:
The multi-function bag is designed as a universal component that can serve multiple purposes: storing chair parts, providing emergency seating, and carrying various outdoor gear. This universal design approach allows a single component to replace multiple specialized items, simplifying the overall system while preserving functional versatility.

AI summary
Various systems and methods relate to an adaptive chair system having (i) a stowed mode in which the members of the chair frame are contained within a compact flexible multi-function bag (MFB), and (ii) a deployed mode in which the MFB is adapted to releasably couple to an arm of the chair to provide a multipurpose accessory chamber. In an illustrative example, the MFB may, for example, fold in on itself in an accessory mode. The MFB may provide various utilities for hikers, for example, by providing a case to receive an inflatable bladder so as to form a pillow. The MFB may receive a thermal liner adapted to maintain, for example, food or beverage temperature. Various embodiments may advantageously provide a rugged, water resistant MFB system in an ultralight form factor that serves as a multipurpose accessory (e.g., to store items), yet provides a compact, adaptive chair frame containment.
