Crumple Zone Project:
Conceptual Model-
I am thinking that we should make either a box model or a cylinder type model and put paper rolls/cones/zig zags on the insides. I think that this would work well because the top of the box will sink in and the cones, rolls, and zig zags will catch and soften the impact of the bottle. Also, I think we should cut slits in the side of the box because it could make the top collapse and add protection and absorb more impact at the top of the box.
Identify the Problem-
The problem is that we have to create a safe and effective crumple zone out, of paper and staples, to protect an egg from a water bottle with 200mL of water in it. Adding to the difficulty, we have to make it as lightweight as possible. We need this crumple zone to absorb the impact of the water bottle instead of it just taking it and smashing the egg.
Generate Ideas-
One idea was to make a box and fill it up with rolls of paper and an X shape in the middle of the box. We stapled together a box of paper, then added the X in the middle, then we filled each open areas of the X with paper rolls. Another idea was to make a pyramid/cone shape. We are still testing this idea out, but we think it could be very useful. Another idea was to make an egg shaped outline of paper, staple it together, and fill the inside with a lot of paper rolls, but his idea did not really work out.
Constraints-
The constraints of this project are: it has to be 4x4x4 inches big, it has to absorb impact, and it can only be made using paper and staples. The crumple zone cannot be very big because who would want a giant front part of a car? Plus it has to fit on the testing platform. The crumple zone also has to absorb impact or the egg will be crushed.
Criteria-
The main criteria of this project is that is should be as lightweight as possible. Using the SAFE design process, our design should be Simple, Appropriate, Functional, and Effective. Using all of this, we should try and make our design more lightweight.
Research-
Weight distribution is a law of physics, we based our crumple zone off of it after trials and lots of errors with other designs.
Possible Solutions-
+Cone
+Pyramid
+Box
+Cylinder
Summary-
Our box with the cushion idea worked the first time, and we are currently in the process of re-designing it for Friday's second round of testing. We are trying to make a better box with as little staples as possible because that is where most of our weight came from. We are also trying to make the bottom only one piece of paper to conserve weight. In the middle, we are going to try and make a smaller cone, but use the same amount of the other items. If we do this correctly, it should work for a second time and be a lot lighter than our previous model.
