Supportive Walker

Abstract

Team 6b will build a walker which is supportive, collapsible, and adjustable. This build is purposed for a toddler with reduced mobility. The intended outcome is the child will maintain greater mobility than without this device.

Problem Statement

The intended user of this walker is a child who has limited mobility. The child is a 3-year-old girl who cannot walk reliably without assistance.

Design Specifications

  1. Support user’s posture
  2. Increase mobility of user
  3. Adjustable
  4. Collapsible
  5. Provide table for user
  6. Entertain user

Background Research

Since walkers are so common, we looked to the internet and past projects for inspiration. Our research lead us to conclude we should build a walker which can adjust according to the user’s growth, collapse for easy transportation, and support the user by a harness or offer some sort of support other than handles alone. Additionally, the walker needs to be light enough for a small toddler to use, so we all agreed aluminum would be the best material choice.

Concept Design 1

The main features of this concept are a scissor-style collapsible frame and a support hoop for a harness. A folding table could be added as well.

Concept Design 2

This design focuses on adjusting for the user’s growth. Instead of a harness, the user should lean with their forearms on padded supports. There is an option for a detachable accessory table.

Concept Design 3

Concept 3 has similar focuses as Concept 1 in that it’s design is focused on collapsibility, and supporting the user with a harness from above. This version includes a stationary table with rounded cutouts for handles.

Selected Concept Design

We initially decided concept 3 was the best choice since it is based on a proven design which could be fabricated relatively easy. However, the client family preferred concept 1.

After looking for existing designs similar to concept 1, we came across a product which can serve nearly all the needs of the intended user. There are available modifications for this walker, specifically a supportive hoop.

Since the walker and support hoop were already engineered and far less expensive than building any of the 3 concept designs, we chose to use this product.

Decision Matrix

Overview of Selected Design

The selected design is a posture control walker by Kaye Products. Necessary modifications include: support hoop, caster wheels, and an accessory table.

Bill of Materials

Document Fabrication Process

Prior to assembly, some of the walker parts were finished in purple powder coat according to the user’s choice.

The client family requested the walker have an accessory table attached to the walker. After assembly, a table mount was fabricated from aluminum. A polymer table panel was then added
