Detailed Design Report: Thickness of Lead Cartridge Wall for Mechanical Pencil
Detailed Design Report (DDR)
The Detailed Design Report is issued by the team developing the concept - the conceptual design team. The conceptual design team deals with the design decisions defining the product. However, the intricate details are issued to an indifferent party to ensure credibility to the design. The indifference of the Detailed Design team allows for variability in the decision making of the solution
Process
The Detailed Design report is a more difficult document in that it requires much research to complete competently. Another aspect that makes the Detailed Design difficult is that collaboration with other team members must be made while being careful not to narrow the range of possible solutions. The Design Detail that I was asked to write up was for the thickness of the cartridge inside a concept mechanical pencil that is to hold 18 pieces of lead. In the preliminary design phase I justified the importance of the detail and how it contributed to the final design of the product. And by doing this, I was able to set reasonable constraints via syllogism along with secondary objectives and criteria. Also, by setting out criteria, I established my personal design values into the design which enhances the credibility of the overall project due to my indifference to the conceptual design. Additionally, I researched different material thicknesses and the design value of durability to assume ideal thickness.
After finding a few reference solutions to the thickness, I realized that not only were the thicknesses different, but the materials were as well which was not in my jurisdiction. Therefore, I had to collaborate with my Detail Design team member responsible for selecting the material for the cartridge. I also had to collaborate with another team member responsible for the number of dividers present in the cartridge, for this determined the volume needed to hold 18 pieces of lead in the cartridge.
After, collaborating with other team members, I used comparison techniques taught in lecture to select the ideal thickness for the pencil cartridge.
