Alumni team tops Collegiate Inventors Competition

On a Friday in mid-November, present mechanical engineering alumna Elizabeth Bianchini ’18 found by herself on stage facing an extremely daunting audience. She was providing within 2018 Collegiate Inventors Competition (CIC) in Virginia, managed by the National Inventors Hall of Fame.

In the front row ended up being an illustrious panel of judges, including the inventors associated with the digital camera, Post-It notes, together with pacemaker.

“The coolest part ended up being showing with a of the most extremely innovative minds of your life time,” Bianchini recalls. “They saw things that no-one else saw until it was apparent exactly how much their inventions changed the planet.”

Bianchini provided on the behalf of a team of alumni that also includes Kyler Kocher ‘18, Ann McInroy ‘18, and Sam Resnick ’18. The team is continuing run Rhino, a rotary hammer accessory might revolutionize the world of masonry. Centered on Bianchini’s presentation, the Rhino team was granted the undergraduate Gold award within CIC.

“It had been my first-time providing about Rhino myself,” she adds. “My pleasure was hard to consist of. I think my genuine enthusiasm the item might have been section of the reason we performed so well.”

Rhino was one of several eight services and products created and developed by students in last year’s course 2.009 (Product Engineering procedures). The team’s winnings on CIC ended up being the culmination of more than a 12 months of work by a large number of student team members, professors, teaching staff, and laboratory instructors.

A fraternity household in disrepair

The selection of students who worked on Rhino in 2.009 didn’t need look far for inspiration. The bricks on group member Sam Resnick’s fraternity house required repair. Resnick took the lead-in trying to find a mason to do the job. He had been impressed because of the expense and time from the project.

The greater research Resnick did, the more he understood there was clearly room for improvement. Bricks usually need to be repointed when every 20 years. Presently, the mortar involving the bricks is removed having an direction grinder and chisel. Considering that the radius of grinder tires is normally bigger than the straight joints between bricks, accuracy actually issue and bricks often get damaged. Additionally, the method kicks up big clouds of silica dust, generating health concerns for masons.

After exploring some alternatives for items to operate on in 2.009, Resnick’s team – Team Orange – decided to deal with stone repointing.

“Brick repointing is everywhere — especially in a spot like New England where virtually every building you go is brick, and frequently historic,” explains Bianchini.

To solve the difficulty, the group of students made a decision to concentrate their attention on rotary hammers as a replacement for grinders. Their analysis unveiled a rotary hammer can pull mortar in huge chunks, nearly eliminating the harmful dust cloud that may envelope masons. In addition it enables better speed — which can substantially reduce time and expense of brick repointing.

On its own, a rotary hammer could be difficult to control and too inaccurate for usage in brick repointing. The team’s innovation, Rhino, is an accessory that connects towards the rotary hammer, manages depth of cut, assists guide masons over the mortar joints between bricks, and offers a straightforward and adjustable conversation when it comes to mason.

“This project had been MIT from the very start. Their particular primary motivator was a building here on campus,” says Warren Seering, the Weber-Shaughness Professor of Mechanical Engineering and another of the 2.009 lab teachers assigned into the Rhino staff. “It connections into one of the themes of 2.009, that will be to encourage pupils to recognize requirements in the world around all of them.”

Presentation rehearse

In 2.009, big groups of 15-20 pupils interact to design and develop a working model of a brand-new item. Underneath the leadership needless to say trainer David Wallace, professor of technical manufacturing, a massive staff of professors, staff, alumni, and Boston area design experts work to guarantee pupils receive a geniune item design experience.

“A best part concerning this course environment usually it’s as near as we causes it to be to at least one that pupils may be inside a year from today at business,” describes Seering. “It’s a great environment for active learning of most useful design techniques.”

Part of the genuine design experience is learning to communicate or present of a item. The course culminates inside a final presentation at the beginning of December in which users from pupil teams contained in front of an large, enthusiastic market in Kresge Auditorium. When it ended up being Rhino’s time and energy to provide, team members Hannah Rudoltz, Kyler Kocher, and Ann McInroy took to the level.

“Presenting at 2.009 had been one of the most interesting things I’ve done,” recalls McInroy. “There aren’t a number of other schools that celebrate manufacturing in the same manner you would a sporting event.”

Through the class to building web sites

Following the confetti ended up being swept away additionally the semester concluded, it absolutely was obvious that Rhino ended up being something well worth pursuing.

For the design and development procedure in 2.009, the Rhino team moved beyond the wall space of MIT and worked with local masons and unions to develop something ideal for their requirements. In springtime for this 12 months, a group of Rhino downline carried on to focus on company case and perfect the look.

For Bianchini, continuing work with Rhino has actually assisted the woman further hone non-technical abilities which is essential as she progresses inside her profession.

“Pushing Rhino beyond the class immersed me in the commercial and appropriate jobs that fill the space between task and item,” she describes. “Now I am even more prepared to begin my own endeavor later during my career.”

When it arrived time to present Rhino and their particular business instance at CIC, more than a year of work by countless individuals paid off. “Winning at CIC is actually exciting as it shows that Rhino is really a product which is valuable up to a bigger market away from MIT,” adds McInroy. “The fact we were able to be competitive in that gifted selection of creators is quite validating.”

As run Rhino consistently progress, Bianchini, McInroy, Resnick, and Kocher will explore business options that will help take Rhino from a concept developed in a class room to a viable product utilized at construction websites everywhere.
