AXLE CANE HELP WITH MOBILITY

NOZOMU ITO


INTRODUCTION

Meet my mom: She is currently 68 and has a physical disability. With this extreme disability, she constantly needs to shift her weight from side to side in order to walk straight. She is a strong, motivated individual who still performs everyday physical activities. However, there will come a time when mobility will be a luxury of the past.


INTRODUCTION

Elderly in America: People 65+ represented 12.4% of the population of the world in the year 2000. However, this percentage is expected to grow to be 19% of the population by 2030. Are we prepared to create a better lifestyle for the growing elderly population?

2000: 36 Million

2030: 72 Million

2050: 87 Million Source: US Census Report “65+ in the United States:2005�


INTRODUCTION

Mobility for the elderly: A cane or a walker ultimately becomes an extension they add to their lifestyle.

RESEARCH PHASE 1

Spontaneous feedback: “It would be great to have a rail next to you all the time.” - Elderly on CTA


RESEARCH PHASE 1

Professional feedback: “We had customers come in with problems not only with their physical disability as well as strains with the use of canes.”- Katelyn, ATI Physical Therapy.


RESEARCH PHASE 1

Areas Affected by Lifting a Cane: A simple cane can cause stress to the shoulder and lower back of the body.

Lifting

Dropping


RESEARCH PHASE 2

Rolling Cane

The free moving casters makes it feel unsecure when moving.

Hurry Cane

This cane needs to be on an absolutely flat hard surface to remain upright on its own.

RESEARCH PHASE 2

Quad Cane

It wobbles onto one side of the feet real easily when I start moving, which doesn’t help my balance.

Flexstick

I sounded like Iron Man as I walked with it.

Amazon User Review


RESEARCH PHASE 2

Initial research conclusion: What an elderly person wants is a device that can be leaned on like a walker, but be as maneuverable as a cane.


DESIGN DIRECTION

Objective: Design a cane that allows you to feel like you're walking with a wheeled walker, providing balance and consistent relief of pressure to the injured leg.


IDEATION PHASE 1

Listening to the body: Natural balance is achieved by weight distribution.


IDEATION PROTOTYPE

Hacking from a toy: I was able to find a simple spring loaded axle from a toy scooter.


FORM STUDY

Ergonomic study of cane handle: A handle possible in provide grip and also shift in weight distribution.


IDEATION PHASE 2

Canes that can balance like a trike: If wheels are attached to canes, then there needs to be a shift in the wheel angle to provide weight distribution and traction.


IDEATION PHASE 2

Support from less: Having wheels that angulate you can get larger weight distribution.
