Retractable Walker With Telescopic Height And Width Adjustments
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing walkers are inflexible and cannot be adjusted in size, making them inconvenient for use by individuals of varying heights and body types, limiting their versatility.
Innovation Solution
A retractable walker design featuring left and right armrest components connected for adjustable width, a horizontal support frame with retractable structure, and front and rear support members with upper and lower retractable structures, allowing for customizable height and width adjustments to accommodate different users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the walker uses a fixed size structure, then the structure is simple and stable, but it cannot be adapted to different user sizes and body types, reducing versatility
Solution Approach 1:
The walker incorporates telescopic adjustment mechanisms that allow the frame dimensions to be dynamically changed according to user needs. The left and right telescopic adjustment mechanisms enable the distance between armrests to be adjusted, while the upper and lower telescopic adjustment mechanisms allow height adjustment of support members, transforming the fixed structure into an adaptable one.
Solution Approach 2:
The walker frame is divided into multiple adjustable segments with independent telescopic mechanisms. The left and right sides have separate adjustment mechanisms, and each support member has independent upper and lower adjustment capabilities, allowing localized adjustments without affecting the entire structure.
2Adaptability or versatility
If the walker incorporates telescopic adjustment mechanisms, then versatility for different users is improved, but the device complexity and number of components increase
Solution Approach 1:
The telescopic adjustment mechanisms serve multiple functions: they adjust both the width (left-right distance) and height (upper-lower position) of the walker, providing universal adaptability for different user sizes and preferences without requiring separate adjustment systems for each dimension.
Solution Approach 2:
The telescopic mechanisms use nested structural designs where inner components are housed within outer components. The telescopic adjustment mechanisms are integrated into the existing frame structure, with adjustment components nested within the support members and connecting elements, reducing overall space requirements and component count.

AI summary
A retractable walker is disclosed, including left armrest component, a right armrest component, a seat, two front support members, and two rear support members. The left armrest component and the right armrest component are configured to be disposed at left and right and connected to each other in a left and right retractable adjustment. The seat includes a horizontal support frame and a seat plate, the horizontal support frame has a left and right retractable structure, and left and right ends of the horizontal support frame are configured to be mounted to the left armrest component and the right armrest component for connection respectively. The retractable walker can be retracted to adjust sizes, thereby applicable to different tall and short, fat and thin populations, which can greatly improve versatility of this product, more convenient to use.
