Using the House of Quality to Design a Rear Anti-Tip Device for Manual Wheelchairs

Amanda Machado, BEng, R. Lee Kirby, MD


A technique commonly used in industry, known as the House of Quality (HoQ) matrix, was used to discover the relationship between user needs and engineering characteristics in the design of a rear anti-tip device (RAD) for manual wheelchairs. The results of the HofQ matrix indicate that the position of the RAD while in its deployed and undeployed states, the number of adjustability increments available to the user, and automatic return to the undeployed position when not in use are the three most important engineering characteristics for the RAD to achieve. These engineering characteristics, if achieved, will have the greatest impact on the customer’s satisfaction.

Disney produced a television show in the mid 1990s called Gargoyles. It's a great show and I'm a big fan. A few years ago Disney started to release the show on DVD. The last release was of season 2, volume 1. That was two years ago. Volume 2 has not been released. Why? Poor sales. So if you should find yourself wanting to support my work, instead I ask you pick up a copy of season 2, volume 1. It's a great show and you might find yourself enjoying it.
