Prototyping Part 1

Alex and I are off to great start. We've decided to tackle the one-handed handle project. We both made sketches of handle ideas and then compared our ideas. We both had similar concepts and decided to work off of Alex's sketch, which was more clear.
 

Initial concept sketch

We then began the process of making a rough prototype out of sheet metal, scrap wood and foam board. The initial model is not accurate at all because at that point we were still vague on how we were going to exactly idealize the design. In order to get a better sense of our direction, we wrote up questions to ask CRI. We also sent them our initial sketch for their opinions.

Our next step was to take a trip to the KSC to take measurements of the erg machines. We also looked up different clamp designs to brainstorm how to attach the handle to the cord. We looked at rod-latch systems such as those found on camera mounts and music stands. Those types of latches tend to be very easy to mount/unmount. These are the clasps we found:

Clasp options

Some options are more refined products and others are pretty industrial looking. After testing them out, we can incorporate features from multiple products to create the ultimate clasps for our handle.

I'm working on learning SolidWorks so that we can create a better prototype that has features that will be reflected in the final design. We are trying to standardize the handle as best as possible, while also working with the curvature of the handle for a secure fit.
