Last July, Tozuda went back to the drawing board. They completely changed the mechanism with an entirely new mechanical solution. The new design provides 360-degree coverage and still detects linear impacts.”It’s funny how things work out because this new, patent-pending design is even more robust than the first,” Jessie relates, “Not only can we calibrate the device for linear forces in all directions, the new technology can also be calibrated for rotational forces. This is critical for concussions in particular. We have beta tested this version of the Tozuda Head Impact Sensor with over 300 football players and 20 construction workers. We are now ramping up for our official product launch happening on Kickstarter this Spring 2018.”
Access to Talent
Jessie is currently running a staff of nine. She and member John Pettit are the only full-time employees at Tozuda, but they fill in the staff with consultants and interns. Jessie met John at one of NextFab’s Maker Happy Hours, a public event that happens on the third Friday of every month. The two quickly became friends after seeing each other in the co-working space all the time. Jessie tells me, “After learning more about John’s 40+ years experience as a VP of manufacturing and sales at Ktron, John consulted for me on a freelance project. This is where we realized we made a great team when working together and had complementary skill sets. Ever since John has joined, we have taken Tozuda from a product still in development to a product that’s ready to launch and scale quickly.”
John knew another NextFab member, Cameron Dye, and in turn introduced him to Jessie. Cameron is now their mechanical engineer. In addition to picking up talent from the NextFab member pool, Tozuda has capitalized on the city of Philadelphia. Jessie explains, “We are able to fill out our team using Philly’s school eco-system. With COOPs from Drexel and student interns from Temple, we’ve built an incredibly diverse team which we love! We have 3 team members from Vietnam, one from Saudi Arabia, one from South Africa, and of course we have the US represented by CA, PA, and NJ.”
Ramping Up Production
Tozuda is now ramping up their manufacturing capabilities. Jessie procured an injection molding machine, “Bertha,” in order to take production and quality control into her own hands. Bertha is a 1974 Boy Machine 15 ton injection molding machine. Jessie bought it from an injection molding facility that couldn’t get the machine to run. Jessie tells me, “I didn’t have a lot of money but I had the time to try and figure it out — it also didn’t help that the manual was all in German and missing pages! All in all it took 9 months to do all the repairs with our CTO Chris. In combination with using the Haas at NextFab to do our tooling for our molds, we have been able to make huge strides with our development without breaking the bank. Now that she is up and running we can run about 3,000 parts in a day running at full automatic.” Tozuda is also offering small batch injection molding services to other members who find themselves in the same position that she was.
In anticipation of their Kickstarter launch and the fall 2018 football season, Tozuda is picking up the production pace. They are also honing their assembly procedures and quality control to ensure that sensors will be ready for shipment. For more information about Tozuda or for injection molding inquiries, go here.
