Breathing New Life into Old Gadgets: (FEB 2024)

In trying to fix a vacuum cleaner found on the street, I learned that the secret to giving old devices a second life isn’t just about making an exact copy but making it better. After I took the vacuum home, I carefully measured the part that was broken and started to redesign it with SolidWorks.

To make the part stronger and last longer, I used some smart design tricks, like adding smooth curves at the edges. These curves, called fillets, are really important, especially for parts made with a 3D printer, because they help spread out the stress over a larger area. This is super important for a part of a vacuum cleaner that has to deal with a lot of shaking and pressure.

I also made some changes to the design to strengthen the parts that would have to handle the most weight. By adjusting the shape and adding these extra supports, I ended up with a part that wasn’t just a direct copy of the original but was actually stronger.

I chose a specific type of plastic, PETG, to make the part because it’s both tough and a bit bendy, which is great for parts that move. The very fine detail setting of 0.1 mm on the 3D printer ensured that the improved design was perfectly captured. The special honeycomb pattern inside the part wasn’t just to make it lighter; it also helped the part be more sturdy by soaking up shocks and spreading out the pressure.

As the 3D printer did its work, I saw how modern tech combined with a bit of engineering creativity can do wonders. This project wasn’t just a simple repair; it was a chance to make the vacuum even better than before.

After the part was printed and put in place, the vacuum worked like a charm. This project showed me that with the right know-how and approach, we can fix our gadgets and even upgrade them, making them last longer and work better. It’s a great example of how thinking outside the box, caring for the environment, and aiming for efficiency are key parts of being an engineer today, and how these efforts can make a real difference in our daily lives.

Haptic: (June 2023)

The study explored the use of over-actuation and a hybrid control algorithm to improve force resolution and transparency. Results showed that over-actuation provides higher force resolution, improving fidelity, while the control strategy enhances transparency. These findings have implications for realistic experiences in virtual and augmented reality applications.
