Ryerson Students Excel In This Year's Extreme Redesign Competition

Every year, the Extreme Redesign Challenge calls upon tomorrow’s engineers, artists and entrepreneurs to design a better future. It is a test to see who can come up with the most creative, mechanically sound, and realistically achievable design using 3D printing. Seven winners were selected and received scholarships for their efforts as well as features on the Stratasys website and blog.

Today, we're sharing the results of Canadian students Matthew Wong & Lewis Carvalheiro - the team at Cimetrix would like to congratulate the team on their 2nd place finish in the Engineering, Post Secondary Education category category of this year's Extreme Redesign Challenge. It is always great to be able to share the success stories coming from our academic partners, and to see Canadian students with presence on an international stage.

It all started in  class at Ryerson University; when their professor gave them the option to participate in the Extreme Redesign Challenge, the two were immediately intrigued. Wong & Carvalheiro began brainstorming different problems to tackle, when they remembered a story of one of their friends getting their bike seat stolen in the school parking lot. Recaling the story, it inspired Wong and Carvalheiro to create a way for it to never happen again.

They started thinking of all the possible ways they could lock the seat without being cumbersome to use or produce. After they found a model that worked, they figured why stop there? They decided to add a retractable fender and a convenient bottle opener as well. And with that, the Fender Lock was created. This seat-locking, dirt-deflecting, bottle-opening design would have been much more challenging to make if it wasn’t for 3D printing.

The design functions by by securely attaching to the frame of the bicycle rather than the traditional seat-post method. It then can be extended to cover over the back wheel of the bicycle, preventing water and other elements to fly up onto the cyclist. When the fender is not needed, it can be retracted and rotated along the hinge to hook onto the lock mechanism secured directly under the seat. The Fenderlock was printed out of ABS plastic, which is avaliable on Stratasys Idea Series, Design Series, and Production Series 3D Printers.

The duo explained how being able to interact with the design and iterative process helped them work out the kinks and continue to innovate their model. The features they would miss on the computer would be clear once they printed it, letting them make adjustments as necessary, until it was what they wanted. 3D printing helped them explore ways and forms that they normally wouldn’t have been able to delve into using traditional methods, test these ideas, and quickly iteratre their design until it was optimized.

Wong & Carvalheiro would like to work on their design in the future, but for now they are focused on their post-graduation lives and seeking opportunities to continue to build their engineering skills.
