Annotated Sketches (D2.0)

Introduction

After knowing what design specifications we had for our design we began to sketch out designs. While sketching we wanted to focus on two different design part that we're different, the sole or other friction source and how the shoe would stay on the foot like laces or velcro. We also drew sketches that show how the shoe might be put together and assembled.

Conclusion

We created many different sketches based on ideas we had for different aspects of the shoes. We considered shoe soles, shoe securing mechanism, and possible other attachments to the shoe. We found the dimensions and realistic characteristics of the shoes that we would be designing. We found that velcro was a good idea for the securing mechanism and that rubber soles were also a good idea to head in.

Introduction

We are using a matrix to compare traits from ideas, designs, and patents that we have seen to a control group and finding what characteristics rank the highest. By doing this we are finding what characteristics are useful to implement into our designs. We determined these characteristics in the previous section C. We based the ranking based off the ISS slippers since it is an example about current shoe that is used in space. We then took our top designs which was velcro shoes, rubber shoes, and glue shoes and ranked them based off the ISS slipper.

Selection Matrix

After looking at similar designs and patents that relate to our product we summarized the characteristics into some simple ideas. We made the control group the current ISS slippers and organized the patterns we found in previous designs and ideas.

Conclusion

We ranked our designs on a one to five scale, with five being better than the control and one being worse than the control. The control used was the socks that are being used on the ISS as an example of current space footwear. Our ranking found that Velcro shoes and glue shoes both ranked as being worse than the ISS socks based on our criteria. Both rubber soles and rubber soles with rubber floors ended up being better than the ISS socks with rubber soles and floors being the best.

Introduction

We originally had difficulty trying to CAD a shoe. Our first iteration was very blocky and not very organic. We then followed a youtube video which suggested using a form based on a cad model of a human foot. We took a foot model form grabcad and used it to make a form in the shape of a shoe around the foot. We then added some important pieces like the sole and arch support.

CAD Conclusion

Our new CAD design took some of the problems of our orginal CAD and phased them out. For example in our orginal design our shoe was to wide at the end and made the heel to round. We fixed this issues in our next iteration by making the sole shaped to fit the foot better and making the heel not round. This helps with fitting and stability. We also changed the material to a cloth woven/knitted material to better demonstrate how the final product would look.

Mock Ups (D5.0)

When developing our mock up we looked at shoe patterns and how to make a shoe pattern. We found that when making a pattern, people use a preexisting base, so we used our foot as the base. We covered one of our feet in masking tape, cut it from the back, and flattened it out to form our pattern. We then copied it and modified it to fit the proper shape we needed. we then attached it to the sole which we based off the outline of one of our feet.

Mock up Conclusion

From this mock up we were able to grasp a better understanding on how we are going to build our next mock up. We found that while this cardboard sole was rigid enough to stand on it wasn't sufficient and it also showed the need to have a sole that is shaped for feet. As the flat sole was very uncomfortable. The shoe being made out of paper showed us the need to have a flexible material for the outside of the shoe, while the paper held the shape of the foot it did not give way and did not fit to the foot. We will research and use a cloth material that can flex and give for a foot.
