This week, we finished the main assembly. First, we attached the brake clutch and pad to the lever. Then, we attached the lever to the wheelchair. In addition to finishing the final assembly, we are preparing for our design review on Friday in which we will showcase our progress on our prototype wheelchair. Our plan for next quarter is to …
During week 7, we posted a picture with 3 different symmetrical pieces that we received. The three pieces were welded together this week to form the lever arm. Welding is a fabrication process of joining the two rods together. This is achieved through fusion, where the two metals are melted. The next step is to send the welded piece for …
This week we finalized the presentation details for our peer review and started to work on our design poster. In our peer review presentation, we wanted to include our revise budget, the timeline for the quarter, who we selected as our sponsors, potential roadblocks and the progress we have made to manufacture our CAD design. In addition, a draft of …
This week, we received the finished product from tube technologies. The top set of tubes is for the lever arm that attaches from the wheel, follows the shape of the wheel, and allows the patient to push forward. The middle set of tubes is for the brake calibers. Lastly, the bottom set of tubes is for the spring return attachment …
This week, we performed a simulation analysis on the lever arm. The goal was to ensure that the brake caliper was not mounted at a location where it would deflect far enough and cause the brakes to lock up. The device was given a simulated 200 N load in the transverse direction at the handle. The handle deflected 5 mm …
This week, we completed the technical drawings for the level arm. We based our drawings from the cardboard prototype that we did last quarter. From this, we realized that the L-shaped lever cannot complete its full motion, moving forward and backward to push the wheel, at a certain point along its motion path. Thus, we attempted to design an optimal …
This week, we selected the sponsors that we needed to manufacture MPOWRD. For the tube bending of the frame, we chose Tube Technology. This small company helped create the lever arms. Due to the very small size of the company, there was very limited information on the company history available on the Internet. For the power coating frame, we chose …
This week, we put together our schedule for the quarter. The goal is to manufacture and create a prototype of the wheelchair rehabilitation device that can be detached from the wheelchair and transported independently. The timeline is as follows: For week three, our plan is to deliver the drawings to the tubing fabricator. For week five, we expect to receive …
This week, we prepared for our senior design review. We attended the workshop held by the School of Engineering where we received feedback on our poster. The reviewers had a chart, ranking topics that needed to be on the poster by level of importance. The background, goals and innovation were the most important parts of the poster. We also spent …
This week, we took the cardboard design that we made last week and built a CAD model. Below is a picture of this model. In the picture attached to this blog post, there are a few major components captured. First, the lever; it is attached to the inside of the wheel and curved around the wheel with a handle protruding …
