For ENGR1200 Design Nature, we were given the task to design a transporting bio-inspired toy with a $50 assignment. My teammates and I were assigned the elephant as an animal. Immediately we made it a goal for our toy to transport kids. To make our idea even better, we wanted the trunk to be able to grasp objects such as logs or peanuts or anything elephant related.
Then I thought it would be cool for the elephant to be able to store the kids’ toys in a hidden seat compartment.
Sadly this idea was ruled out when we were told that the thing that was transported (kid) was not able to power the transporter. So my team pushed the idea of transporting water. Mike found a great way to implement one way valves so that, when pumped, the water will suck or squirt, depending on the pump used.
This is a sketch of the hand toy we bought. The hand can grasp objects by utilizing the tension in plastic bands within the finger segments. This was great inspiration for our trunk design, which was led by Rachel.
One part of my responsibilities was to design a sturdy head frame. From delrin (a plastic material), I had to make a realistic elephant shape so that Rachel can tightly sew over. The sketch above shows my preliminary idea for arcs. The sketch below is the final arc design.
The detailed sketch below shows how the delrin is attached to the wooden body.
My other responsibility was to design a wooden body that was sturdy and safe enough for our raucous fourth graders.
