Define a problem
Generate Concepts
For the histogram I measured each of my 27 cubes using a dial caliper, I used a dial caliper because all of my measurements had to be very precise, more precise than a ruler could make them. I took all of the measurements and put them into a graph, which in this case is called a histogram. After filling out my graph I had to make sure that they were all within three standard deviations of the mean, the standard deviation is how far away from the mean the data is on average. I took the mean and added and subtracted the standard deviation three times, and if any of my values weren't inside of it then I would've had to throw away the cube and get a new one, but all of my values were inside.
Develop a Solution
Construct and test Prototype
In order for the cube not to move you had to constrain it from two of the three axis, using the flush and mate options. The three axis are x, y, and z. You have to mate each piece to another piece then flush them so that they won't move up or down. This ensures that your cube fits together snugly.
Evaluate the solution
I had 5 people solve my cube, only two could solve it. Their times were 2 minutes 52 seconds and 45 seconds, they were both 15 years old. Out of the other 3 that tried it one was 15 and the other two were older than 40. I think that the reason the younger people were able to solve it and the older people were not as creative as younger kids, they have less reason to try to solve it as well because they are not as competitive and have nobody to try beat with it. So if one age group would be better at this it would be the younger age group because of their creativity. But if I had to change my cube to make it easier I would take one of the pieces from the green piece and put it on the red piece. Then solving it would make more sense when solving it.
Present the Solution
When I first started the project the first thing I did was grab 27 wooden cubes and measure all of them using the dial caliper. I numbered all of the cubes so that I could remember which one was which, then I created a list in excel. Then I used the list to calculate the mean, median, mode, minimum, maximum, range, and finally the standard deviation. I created 6 bins that were .05 apart from each other, and created a graph using those bins. Then using the mean I subtracted and added three times individually to figure out how many were inside of each standard deviation, keeping the ones that were inside three standard deviations. After I finished all of this I made 20 drawings of pieces that were made of 4-6 cubes, and chose 5 that would fit together well for my cube, which had to be 3 blocks by 3 blocks by 3 blocks. I took building blocks that were 5 different colors and put together my 5 pieces with them to try out my solution and make sure it worked, and it did. Then I glued all my pieces together into their pieces and colored them. After that I started to make my pieces on inventor, then created technical drawings in inventor and by hand. I also put my cube together in inventor and created a spreadsheet of my cube that shows how to make it. When someone says "I used the design process to solve the problem at hand" they mean that they followed the steps of the design process in order to solve the problem that they have. For the define problem part of the design process I looked at my design brief/constraints to see what I could or could not do. For generate concepts I sketched out my pieces for my cube and chose the 5 I wanted to use. Then to develop the solution I went on inventor and created my pieces, and glued my wooden blocks together for the construct and test prototype part. For evaluate the solution I gave my cube to other people for them to solve and I timed them while they did. Finally for present the solution I created this weebly to show how I completed this project.
