Thanks to everyone who participated! There were so many unique solutions for this tough, mechanical challenge. We believe these winners are the best solutions. We took an in-depth look at all 8 of the technical specifications and rated each entry on a scale from 1 to 10 based on how it performed in those areas (0 being "not completed" and 10 being "fully completed"). Congratulations to all of the winners and to all of those who participated in this challenge!
It is a great pleasure to see that in such a short time and based on our requirements so many engineers were able to create innovative and competent solutions. Entrants asked lots of additional questions and they were really familiarizing themselves with the task. We were impressed!
Very good and extensive entry, everything is well explained and also tested on a prototype. All the main criteria are covered.
