Happy Throwback Thursday! This week we interviewed Nowsherwan (Nash) Sultan of Origami Chainsaws. The team set out to create an anti-vibration system for a string trimmer to reduce vibrations generated by the motor and improve user experience.

Q: Could you give us a brief description of your project for those who may not know about it?

A: The main goal of our project was reduction of vibration that is generated by the motor in a electric string trimmer. String trimmers are commonly known as weed wackers and after prolong use can be uncomfortable to use because of the vibrations.

Q: Where did you first draw inspiration for the idea of the “1-String Trimmer Anti-Vibration System,” for your Capstone Design Project?

A: For our initial ideation we drew inspiration from different items that are used for vibration reduction in our daily lives, such as one of our damper ideas was an inspiration from dampers used in transmission lines. Then one of our member Adam mentioned how he had heard of Sorbothane a material that was used to reduce vibrations in blenders.

Q: What was the design process like and how did you and your teammates come together to finish your project?

A: The design process initially included all the members coming together to experiencing the string trimmer firsthand so we could all understand how the vibration felt. From there we all came with ideas and used the design matrix to choose the best solution.

Q: What were some of the problems that you faced along the way and how did you overcome those obstacles?

A: One of the issues we faced was finding a cheap quantifiable way to measure the vibration for which we developed our own testing rig using an Arduino and tri axial accelerometers, costing less than a 100$ while professional equipment can cost thousands of dollars.

Q: How did it feel to work with TTI and how did they help you with the creation of your project?

A: TTI was a great sponsor our mentor Fahad made sure he was available for any of our question and answered them promptly. He also made sure all the materials and data that was needed was delivered or shared with us promptly.

Q: What do you think made your team successful in creating your project?

A: I believe the key for our team to being successful was early planning and work distribution. We developed a prototype early on during the semester and determined what works and what doesn’t which helped us focus on the best possible solution.

Q: Do you have any advice for future teams?

A: My suggestion to all teams would be trying to set weekly deadlines and start working on and finishing their prototypes as soon as possible. In fact, in parallel with their modelling. As not all things will go according to plan. Also, setting people responsible for certain areas of the project was very helpful and led to a smoother finish to the project.

Happy Throwback Thursday! This week we interviewed Jasmine Hornbeck of Chock It Like It’s Hot. The team set out to create a new chocking system with imbedded sensor network that aims to reduce compliance issues that Delta Airlines is currently facing.

Q: Could you give us a brief description of your project for those who may not know about it?

A: Aircrafts are often left without their wheels chocked or they’re simply improperly set which results in the pilots having to engage their parking brakes more than they need to — resulting in these unnecessary maintenance costs. Not only does this project allow for the opportunity to save Delta Airlines money but improperly set chocks are quite dangerous, as this can put aircrafts, facilities, equipment, and potentially people in harm’s way. The objective of this project is to reduce existing compliance issues involving the chocking of Delta’s aircrafts and we accomplished this by integrating force sensors in existing chocks that would activate when the plane has been chocked and then notify essential personnel.

Q: Where did you first draw inspiration for the idea of the “7-Aircraft Parking,” for your Capstone Design Project?

A: We knew we wanted to work with Delta, and this was the idea that interested us most as a team. It was summer capstone, so the options were a little more limited.

Q: What was the design process like and how did you and your teammates come together to finish your project?

A: To meet the design goals, our team came up with several concepts that encompassed various geometries and implementations. These concepts fell under three categories — modification of the original chock design, an entirely new chock design, and modification of airports. Modifying the airport, although novel, was definitely not feasible for a capstone project. Since we were trying to finish it in a summer, the amount of testing that would go into an entirely new chock design was also not ideal. We decided it was smartest to take advantage of what worked about the existing design and adapt it to fit the new needs identified by Delta.

Q: What were some of the problems that you faced along the way and how did you overcome those obstacles?

A: Meeting the design constraints proved very difficult as we were trying to make a new chock that could withstand the forces exerted by Delta’s planes and also integrate a sensitive sensor network. This also made meeting the weight requirement very difficult because we needed all of these new electronic components which increased the weight of the chock and sensitivity to forces yet we couldn’t remove material without compromising the structural integrity.

Q: How did it feel to work with Delta Airlines and how did they help you with the creation of your project?

A: It was pretty awesome – we met with our sponsors weekly to update them on our progress, and they would give us their insight such that we could troubleshoot any potential problems before proceeding. They gave us a tour of their facilities and we were able to test our prototype on real Delta planes so all in all, it was a fantastic experience.

Q: What do you think made your team successful in creating your project?

A:

1. Effective communication, within our team and also in presenting our idea to others.
2. Anticipating problems in designs before implementing them
3. Creating sub-teams and identifying each team member’s strengths early on
4. Having similar goals of how we wanted to perform in the class – if some teammates want to win and some simply want to pass, there will be discrepancies in the quality of deliverables.

Q: Do you have any advice for future teams?

A: Don’t over-engineer something and be realistic about your timeline. The simple solution is often best so it’s important to find a compromise early on about finding that feasible, implementable solution for industry but also being excited about your design.

Thank you Jasmine for sharing your project with us!
