Collapsible Rolling Walker With Pivotable Legs
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing rolling walkers do not adequately accommodate diverse user needs and environments, particularly in terms of collapsibility and transportation, as they often require significant space and are not easily adaptable for frequent vehicle transport.
Innovation Solution
A collapsible rolling walker design featuring pivotable front legs and handle arms that align in a compact configuration, allowing for easy storage and deployment, with a lightweight and weatherproof molded plastic seat assembly and adjustable handle components for user convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a rolling walker is designed with a standard non-collapsible frame, then it provides structural stability and support during use, but it occupies significant space and is difficult to transport in vehicles
Solution Approach 1:
The rolling walker frame is divided into collapsible segments that can be folded relative to each other. The front legs and handle arms are segmented to allow the frame to collapse into a compact configuration for transport while maintaining structural integrity during use.
Solution Approach 2:
The frame transitions from a static, fixed configuration during use to a dynamic, collapsible configuration for transport. Pivot joints and folding mechanisms enable the frame to change its shape and volume adaptively based on whether it is being used or stored.
2Ease of operation
If the rolling walker is made lightweight for easy handling, then it improves ease of operation, but it may compromise structural strength and stability
Solution Approach 1:
The frame utilizes composite material construction combining lightweight materials with high-strength components. This allows the overall weight to be reduced for ease of handling while critical structural elements maintain sufficient strength and stability during use.
3Ease of operation
If the rolling walker includes a seat for user comfort, then it improves ease of operation, but it increases the overall weight and complexity of the device
Solution Approach 1:
The seat assembly is designed as a multi-functional component that serves both as a user seat and as part of the collapsing mechanism. The seat can be folded or removed to facilitate the collapsible configuration, reducing overall structural complexity while maintaining comfort functionality.
