Design And Development Of A Transhumeral Prosthetic Mounting System, Michael Bertini, Zachary Dominguez, Joshua Morin, Elizabeth Palumbo Apr 2006

Design And Development Of A Transhumeral Prosthetic Mounting System, Michael Bertini, Zachary Dominguez, Joshua Morin, Elizabeth Palumbo

Assistive Technology Resource Center Projects

For those with amputations, prostheses are important tools which are needed to perform many activities of daily living. Ideally, a prosthesis enables the user to perform activities with the same freedom as a physically able person. For those with trans-humeral amputations, however, effective prosthesis use is often hindered by the complexity of the glenohumeral joint. Current methods of prosthesis attachment for those with trans-humeral amputations severely limit load bearing capability. The goal of this project was to design, analyze, manufacture, and test a device that increases current axial and torsional load bearing capability without limiting the range of motion in ...


The Design And Manufacture Of An Elevating/Articulating Manual Wheelchair Legrest, Eric Couture Apr 2006

The Design And Manufacture Of An Elevating/Articulating Manual Wheelchair Legrest, Eric Couture

Assistive Technology Resource Center Projects

For people bound to a wheelchair, the ability to elevate one's legs is as much a comfort concern as it is a health concern. The elevation of one's legs changes the user's sitting position, thereby increasing their comfort level while at the same time increasing circulation, ultimately aiding in the prevention of pressure sores and lower extremity swelling. Unfortunately, the motion of current legrests on manual wheelchairs does not accurately match the motion of the user's lower leg. This mismatch of motion causes the legrest to push up on the leg, shortening it while applying torque ...


Design Of A Power-Assist Hemiplegic Wheelchair, Keith Liadis Mar 2006

Design Of A Power-Assist Hemiplegic Wheelchair, Keith Liadis

Assistive Technology Resource Center Projects

Current one-handed manual wheelchairs are difficult to propel because one arm can only provide half the power that is ascertained in a two-handed manual wheelchair. A power-assisted hemiplegic (one-sided paralysis) wheelchair was developed that can effectively be propelled with one arm while remaining maneuverable, lightweight, and foldable. An existing manual wheelchair was minimally modified and fitted with powerassisted components that could alternatively be attached to a wide range of manual wheelchairs. The design implements a motor and gear train to power the wheel on the user’s affected side, encoders on both rear wheels to track wheel position, and a ...


Utilizing Assistive Technology Design Projects And Interdisciplinary Teams To Foster Inquiry And Learning In Engineering Design, Janis P. Terpenny, Richard M. Goff, Mitzi R. Vernon, William R. Green Jan 2006

Utilizing Assistive Technology Design Projects And Interdisciplinary Teams To Foster Inquiry And Learning In Engineering Design, Janis P. Terpenny, Richard M. Goff, Mitzi R. Vernon, William R. Green

Center for e-Design Publications

In industry, successful products and systems usually require a collaborative design process with a multitude of participating stakeholders (customers, sales/marketing, industrial designers, engineering designers from various engineering disciplines, manufacturing, distribution, etc.). Addressing this future work environment, interdisciplinary teaming has become an important element of student design projects. For the last several years at Virginia Tech, interdisciplinary design projects have been created with teams of students from the first year Exploration of Engineering Design course in the College of Engineering and students from the second year Industrial Design Program in the College of Architecture and Urban Studies. While students and ...
