UD
Universal design is a relatively new paradigm that emerged from "barrier-free" or "accessible design" and "assistive technology." Universal design strives to be a broad-spectrum solution that produces buildings, products and environments that are usable and effective for as many people as possible, not just people with disabilities. UD is basically designing something that can be used by the greatest number of people. For my project I designed an airplane that has wide doors and halls so that people with wheelchairs can get around easily.
Dumb Project
Because UD is not specifically for disabled people this project was pointless!!!!! The majority of the people are not disabled thus there would be no reason for a spray bottle that could be used by the disabled (for example). UD makes production and maintenance costs go way up which is why companies don't want to do it.
