Product Function
The operation of this particular umbrella was very simple. The pictures and video below depict the general use of an umbrella.
The umbrella consists of a handle which is connected to a telescoping shaft. The telescoping shaft is a mechanism that extends in order to expand several mechanical arms, or spokes, outward when the umbrella is in use. The extension of these spokes serves to expand the canopy, made of polyester, producing a dome shape. This dome shape deflects rain and snow from reaching the user. The concentric tube is located at the top of the shaft. It holds the spokes firmly together and is used to extend the telescoping shaft. There is a locking mechanism also located at the top of the telescoping shaft so that the canopy does not close when the user is holding the umbrella. To collapse the umbrella, the concentric tube is pulled downwards to shorten the telescoping shaft and contract the spokes. The umbrella is then stored.

Usability Study
After using this particular umbrella, numerous issues have been encountered. The polyester material is very loosely connected to the spokes. This results in an ineffective umbrella where the area of coverage from preciptation is decreased. Furthermore, the spokes of the umbrella was observed to have many moving parts. The outcome is a sacrifice in strength. A common outcome is bending of the spokes due to excessive winds. We noted that a stronger mechanical design for the spokes was needed for the umbrella. Additionally, precipitation contacted the user during use when high winds was present. During our study, snow reached the user in a direction perpendicular to the position of the umbrella. This also diminished the effectiveness of the umbrella. Finally, storing and cleaning the product was a major issue. It was observed that after use, many users commonly shake off the excess water from the umbrella onto the floor of the location they enter.
