Deliverable: Looks-like model
Today we completed a looks-like (not functions-like) model. We needed to create a model that used cardboard shaped like the metal we're using. The model for today didn't need to hold the bike's weight- it just needed to look like it could, potentially. The dimensions are to scale as best we could construct.
Our bike stand condenses to 4.5" wide, extends to a little less than 9", and is 16" high. This adjustability accommodates our measurements, which dictated we need a range of 5-9" wide and 15" high. Considering we measured bracket width from the outside of one bracket to the outside of the other, our model works well for the variance in bikes.
This model is made from cardboard, tape, hot glue, foam, and a screw/nut for the adjustment mechanism.
This is our adjustment mechanism. We have a slit running down the middle of the outside feet and the screws that are pushed through the middle feet goes through the slits. The nut goes on the outside of the feet. It tightens to hold the feet together, or loosens to allow it to move.
We had to make pieces that mimicked the shape of tubing and angle iron, to show the welder exactly where and what to weld.
Our bike stand when it's completely scooted in.
We noticed that the bracket supports can't be constructed from angle iron. We had to plan for tubing, which doesn't look at good and I don't think it will be as supportive. On Monday we'll ask if Amy can buy us flat metal. It's more expensive than the other metals we're using, but considering we only need half a square foot the price should be reasonable.
Tomorrow (11/11) we'll present our idea to Amy and maybe the class and see if they give us feedback. If everything looks good, we'll submit our plan to the welder and get a working model soon. I know I've been saying that for a while but this time I mean it!
I really like the way you solved the two-piece problem! I also think this design looks way sturdier than the original prototype.
ReplyDeleteThe way that your group solved the adjustment issue was really clever! It also looks inexpensive.
