Multi-Legged Folding Cane Chair for Stable Portable Seating
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional walking canes with integrated seats, or 'cane chairs,' lack stability and comfort due to their multi-legged design, which makes them difficult and dangerous for the elderly and disabled to use, and they are often bulky and cumbersome in appearance and function.
Innovation Solution
A multi-legged folding cane chair with a seat, backrest, armrests, and handle that unfolds into a stable chair while maintaining the functionality of a walking cane, featuring a large base perimeter and adjustable components for enhanced stability and portability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multi-legged design is used for cane chair, then support function is provided, but stability and ease of use deteriorate
Solution Approach 1:
The multi-legged structure is segmented into individual legs that can be independently positioned and adjusted. Each leg acts as an independent support element that can be configured to optimize stability, allowing the chair to adapt to different ground surfaces and user needs while maintaining overall structural support.
Solution Approach 2:
The legs are designed with adjustable positioning mechanisms that allow dynamic reconfiguration of the support base. Users can adjust leg positions and angles to create optimal stability for different sitting positions and ground conditions, transforming a static structure into a dynamically adaptable support system.
2Adaptability or versatility
If multi-legged design is used for cane chair, then support function is provided, but ease of operation worsens
Solution Approach 1:
The leg adjustment mechanisms are designed to be self-adjusting through simple user actions such as weight shifting or basic manual movements. The structure utilizes the user's own body weight and movements to trigger locking and positioning mechanisms, eliminating the need for complex controls or assistance from others.
3Adaptability or versatility
If seat is placed at top of cane near handle, then cane functionality is maintained, but stability and safety deteriorate
Solution Approach 1:
The seat is positioned in a third dimension below the handle level, creating a vertical separation between the cane handling function and the seating function. This dimensional arrangement allows the user to maintain a low center of gravity for stability while keeping the handle accessible at the traditional cane height, effectively decoupling the two functions spatially.
4Adaptability or versatility
If conventional cane chair design is used, then seating function is provided, but appearance and portability worsen
Solution Approach 1:
The chair components are nested within the cane structure when folded, with the seat folding into the cane body and the legs collapsing into a compact configuration. This nesting arrangement allows the cane chair to maintain the slender, elegant profile of a traditional walking cane when not in use, while fully transforming into a functional chair when needed.

AI summary
A multi-legged foldable cane chair with a folding geometry such that the members fold into a cane-like shape and unfold into a chair-like seat. The members and braces are joined such that one rear leg, one front leg, one armrest, and one seat bar comprise one side of the cane chair, while a rear brace and front brace separate the sides of the chair, and a seat and backrest provide areas for the user to sit and relieve weight. A handle provides a hand grip if the cane chair is used as a walking or standing aid.
