Team Vision for Problem Definition PhaseActions needed to define problem:
- Determine the needs and abilities of children with cerebral palsy through research and conversations with the customer
- Assess drawbacks of current products in meeting these needs
- Determine the scenarios in which the product will be used
- Determine the project requirements based on the scenarios
- Define time constraints and create timeline estimate
- Identify possible risks and obstacles that may occur and mitigate them
Problem Statement: A modified ride-on car is a mobility device that allows children with mobility related disabilities to participate in social activities with their peers. This device allows the child to move independently and learn the motor skills they’ll need as they mature. As of 2007, University of Delaware’s Go Baby Go! Program creates customizable ride-on cars for children with limited mobility to open up their cognitive, social, and motor development.
The goals for this project are to analyze current designs from Go Baby Go! to modify the ride-on car to be used by a child with disabilities between the ages of 1 and 3 years old and to be controlled by the caregiver if needed. Some areas to be improved upon on these current designs are client specific controls, stability, physical support, and remote assistance. It is important to be able to easily place, secure, and remove the child from the vehicle. The expected result of the project is a functional prototype vehicle that can be used by the client. The resulting design must meet ASTM and ISO safety standard for ride on toys and powered mobility devices.
Cerebral Palsy (CP) defines a group of permanent movement disorders, with symptoms appearing in early childhood. Symptoms include, stiff/weak muscles, poor coordination, and tremors, which stems from abnormal development or damage to the part of the brain that controls movement. Babies and young children especially have trouble with sitting up, crawling, and walking, and may end up using a powered wheelchair as they age to move around. Currently, there is no cure for CP, but therapy, surgery, and medications can help.
Our MSD team is focusing on solving the problem of children with CP having limited mobility. Our aim is to modify a children’s ride on car to allow the children to open up their cognitive, social, and motor development. The ability to move independently helps a child interact with their peers, explore the world around them, and begin to learn the motor skills they’ll need as an older child. Our ride-on car is to be developed for one specific child, named ‘A’ with CP, to be used between the ages of 1 and 3 years old. Our car will be based on a design from University of Delaware’s Go Baby Go! (GBG) program.
Our team, ZoomTots RIT, will modify a GBG design in order to specifically meet the needs of A. For example, children with CP may have difficulties gripping/controlling a joystick, so this will not be included in our modified car design. Our car will also be used as a transition into a powered wheelchair, since powered wheelchairs for young children are particularly expensive and quickly outgrown.
