Design Problems

Fostering Practical Application in Engineering Graphics

The design problems section bridges the gap between theoretical concepts and real-world applications. Aspiring engineers and designers will find this section useful for honing their problem-solving skills and applying the principles of engineering graphics to practical scenarios. Through a collection of engaging exercises and challenges, this section encourages students to translate their understanding of concepts into tangible solutions. By grappling with design problems that mirror the complexities of the field, students will not only enhance their technical acumen but also cultivate a mindset that embraces innovation and efficiency—a hallmark of successful engineering practice.

Parametric Fuel Tank

Scenario A small company manufactures plastic tanks suitable for a variety of purposes including fuel tanks for the hobby remote control (RC) market. In addition to their standard line of fuel tanks, they want to offer fuel tanks in custom configurations. You can see an example of one of their tanks here: Fuel Tank.

Mold Design – Rotational Molding

A small manufacturing company want to manufacture small fuel tanks for the hobby remote control (RC) market by a process known as rotational molding. Design a roto-mold for this tank: M40 FUEL TANK to be made from cast aluminum. The mold can be any number of pieces, but the fewer the better. A draft can...

Carnivore 212

(in progress Fall 2023) The Carnivore 212 is an near clone of the famous Harbor Freight Predator 212 which is a near clone of the Honda GX160. It is used as a case study for manufacturing engineering technology courses at the University of Memphis. References Predator 212 Manual

Bike Repair Stand

Design a bike repair stand that can be clamped to a workbench that has a thickness between 1.5 and 2.0 inches. The stand should include a clamp. Design the clamp to be cast aluminum. The clamp mechanism can be toggle or screw variety. The the stand frame should be made of tubular steel. The stand...

Bike Light Housing

Design a plastic housing for the Kitronik rear bike light kit. The battery holder and the PC board should be mounted firmly in place. You may use the screws provided or design a snap-fit retaining feature. Note: The screws included in the zip file require a hole diameter of 2.25 mm. The housing should include...

30 Note Music Box

This 30 note music box can be the basis for a variety of engineering technology projects. 3D and 2D files are available below. There is also a 15 note box that is less expensive. Reverse engineer the box design (more photos) Design processes and tooling for individual components Design a housing for the movement. Be...

Phone Holder

Design a case that can hold your phone. Provide attachment points for however you use your phone (boom attachment, microphone, lights, handles, etc). Provide a means of assembly and disassembly. Be sure to include a way to access buttons and charging and other cables. 3D print your design and demonstrate that it works the way...
