 Integrated Transport System for Children with CP Progress Presentation Group 14 David Dwight, Gayathri Srinivasan, Joseph Tejan

Project Need  Cerebral Palsy (CP): a group of permanent, non-progressive, movement problems  Transport modalities formed  Mobility means access  Education, social activities, sports teams  Estimated 500,000 children with CP  77% with spastic CP (CDC)

Surveillance of Cerebral Palsy in Europe (Eckung E, Hagberg G, et al)

Project Scope Design an integrated system that is easily transported and intuitive and fully functional Purpose A) Develop a theoretical model B) Identify adjustable/customizable parts C) Create physical prototype of key elements Goals Due to time and funding constraints a fully realized physical model will not be produced Exclusions

Design Requirements Cost and Construction < $1500 system Lightweight but durable Portability and Weight Compact; fit in average trunk Loadable into car, train, etc. Functionality Intuitive to convert Equally functional to each system Safety Prevent tipping Longevity of product

Design Alternatives: Overview  The designs loosely fall into two main categories  Branches for further investigation of alternatives  First, System Packaging  Create ability for various items to be attached or stored into neat system  Second, System Conversion  Items are combined together and convertable

Design Alternatives, cont. Features: Telescoping cane / wheelchair handles Walker storage on back of wheelchair Features: Telescoping cane / wheelchair handles Walker storage underneath wheelchair Features: Uses folding chair design Front assembly of walker attachable Bag on wheelchair for storage

Design Alternatives, cont. Features: Spring-loaded seat concept Naturally in the upright position Primarily walker Features: Added seat concept Detachable, foldable seat Primarily walker Features: 3 sets of wheels concept Native position as wheelchair Rotating set of wheels for walker

Safety F = 58.8 N Max t =.88 Nm F = 19.6 N Max t = 1.58 Nm F = 14.7 N Max t = 2.35 Nm

Analysis: Materials Examined frame material, tubing shape, nylon vs. vinyl, wheel material, wheel functionality

Analysis: Designs  Walker Stored Underneath design scores highest on weighted Pugh Chart

Walker Stored Underneath Wheelchair  Advantages  Better safety and stability  Functionality is optimal since in combines individual systems  Comfort of person is high due to full wheelchair design  Easily fulfills weight bearing guidelines  No need for collapsing mechanics on wheelchair  Disadvantages  Cost  Weight
