Pinching Problem
For my internship project I was assigned to fixing a problem some of the ABX-500, the 500 for short, costumers were having. The problem was that the hose would get pinched in between the rollers and the clamps. The first step I took to try and remedy this was find out what it would take to make this happen. After plenty of tests I found out it didn't need a lot to pinch the hose. After all of my testing was done I had a conference with Jeff, another engineer. We talked about solutions and extra tests that would go along with them. The two test were to try and see at what angle would make the hose get pinched in the slightest and to see how much I would need to add to the original guide block to keep the hose from getting pinched.
After all of that was done I worked on some solutions. One would simply extend the original guide block and add a bit of a angle on the edge to and the other would make the entrance look like and X, thus the nickname "X-box".

Above you see part of the "X-box" in both a 3D CAD program, called Solidworks, and on a drawing. I had to learn how to use this program and make my own part so that the drawing could go through the machine shop(bottom left). It took about a week to complete the parts I needed. After they got out of the shop I went directly to the pump house to test my parts. I found that the block extension worked. I had expected the "X-box" to work the best out of the two, but first of all it allowed the hose to get pinched and secondly it allowed the smallest hose to slide in-between one part of the X.
Once all of my testing was done I wrote up all of the data I collected to hand over to the engineering team so that they could continue off from where I left. Below is a picture of the hose fitting in the X.
