Road Recorder Removable Hard Drive System   Industrial Design Ergonomic Studies   Objective We needed to create a removable hard drive and receiver bay that was easy to use, reliable, rugged and durable. It provides the portable data part of a digital video recorder used on bus transit systems to deter crime and vandalism. The handle had to be comfortable and installation of the drive had to be intuitive and error free. That meant creating a handle that was self evident and easy to use by a bus driver but did not present an invitation for abuse by vandals. Other challenges included creatig a strong and rugged assembly to withstand the harsh bus environment yet visually fit into the office environment. The solution had to be very cost effective.   Results The scalloped finger grip solution gives plenty of room for the necessary leverage required to remove the hard drive from its bay, yet does not resemble a conventional file drawer grip that temps vandals. Both units have a channel on one side only that prevents incorrect insertion. For strength, the hard drive case is extruded aluminum with injection molded endcaps. The simple form of the unit allos vertical or horizontal installation in the bus and office environment. It is the current market leader in its category.
