SHOPFREE

Project Overview

For parents with disabled children, grocery shopping can be difficult. Imagine trying to push both a wheelchair and a shopping cart—it’s not the simplest “Tuesday-night-after-a-long-day-at-work” task.  Our team aimed to find a solution to this problem.

We discovered a solution that is adaptable to every wheel chair type, and portable for parents.

Skills Developed:

  • Need Finding

  • Lo-Fi Prototyping

  • Storytelling

  • Video Production

  • Presentation skills

CURRENT SOLUTION: CAROLINE'S CART

ISSUES WITH CURRENT DESIGN
  • Requires stores to purchase these carts for a small population of consumers

  • Including a chair in the cart results in less space for groceries

  • Requires children to be lifted from their wheelchair to the cart

  • Only accessible to children able to support their upper body weight

IMPORTANT STAKEHOLDERS

DESIGN RESEARCH

Spoke​ with parents and children with disabilities as well as professional experts to identify user needs and requirements, including:

  • Limitations of children, ability to support their upper body weight, neck, etc

  • Variation and diversity in wheelchairs: shapes, sizes, needs during operation

  • Federal regulations on devices intended to support the disabled

Discovered:

  • Parents need our device to be transportable through a minivan

  • Device needs to be easy to set up and use

  • Device needs to make sharp turns around shopping isles

  • Device should be an attachment for already existing wheelchair (many kids can't leave their chairs easily)​​

  • Additionally, wheelchairs are ALL different shapes, sizes, needs​

  • Needs to be low cost

INITIAL PROTOTYPE
FUTURE STEPS

  • Implement a precise steering module

    • Automatic controls​

    • Detect changes in atmosphere and automatically correct/adjust direction and speed

  • Test in real life with our end users

    • Point out flaws​

    • Pin-point error

    • Get feedback from parents, children, stores
