Developing the DAR quickly was critical to the company. Therefore, the company chose 3-Dimensional Services and its sister company Urgent Plastic Services (both located in Rochester Hills, MI) to help produce the prototype components for the front main bezel and function controls. The two companies offer rapid prototype services, including design, engineering and analysis, in-house tool construction and complete building of first-off and low- to medium-volume production. Urgent Plastic Services specializes in injection-molded plastic prototype parts.
Dell provided the companies with CAD files for seven components. First-off parts only took 13 days to produce. However, when those parts were not usable, the company was given in-house access to design and engineering terminals, team leaders and technicians. Suggestions were offered to improve the part's manufacturability and function, without altering appearances. These modifications were approved and implemented quickly.
Design modifications involved adding structural stiffening and strengthening elements to the bezel's backside. The goal was to provide structural integrity without increasing bulk, raw material requirements and costs. Through design and engineering analysis software, and some trial and error, the optimum locations and minimum material usage configurations for these stiffening ribs were developed.
Within 2 months, from start to finish, 5,000 components were ready for DAR launch and beta testing.
