Abstract/Summary
Helical Products needs a new product display stand that will demonstrate their custom springs, couplings, and u-joints. Their current display stand, a marble run contraption, is large, loud, and difficult to transport, so they would like the new stand to remedy these issues. The goal of this senior project is to create a display stand that captures the attention of their customers with dynamic product demonstrations while addressing the issues outlined above.
The new display stand is also a marble run contraption, but instead of being almost 4 feet tall and 3 feet long, it is 23” tall, 26.25” long, and 11.75” deep. Additionally, instead of requiring transportation in 3 separate parts, it can be transported as a whole assembly, weighing about 39 pounds. In the final design, the display stand can be divided into ten major subassemblies that each focus on a major component. Six of these subassemblies are for Helical Products’ custom parts, which are the lateral bending spring, compression spring, torsion spring, parallel misalignment coupling, u-joints, and the wrap-spring clutch. Two of the subassemblies are designated for the marble track, and the remaining two subassemblies are for the motor housing and the stand’s frame. The majority of parts in this stand are custom-designed 3D printed parts made of PETG, while other parts include necessary secondary components such as standard couplings, shafts, bearings, and mounting plates. For a single display stand, the estimated material cost is about $1550, not including shipping, labor, or Helical components. For Nylon filament components replacing the PETG the cost estimate increases to $1700.
