A startup company that makes women's shoes with interchangeable heels is using SolidWorks three-dimensional design software to being its product to market faster, and at a lower cost.
Day2Night Convertible Heels, started by CEO Candice Cabe, developed the idea when she was packing her suitcase for a business trip: Just bring one pair of shoes, with different sizes of heels that can be easily changed?
The company was a finalist for the MassChallenge, and was funded by Kickstarter.
Day2Night worked with Fisher/Unitech, a reseller of SolidWorks 3D software based in Troy, Mich.
The biggest challenge comes from the need for strength. The shoe has to tolerate the weight of wearer over a variety of heel heights, some of which are intricate and curved. Using SolidWorks and 3D printing equipment, the engineering team at Day2Night determined the optimal weight-bearing load pressure for the show.
“This product required a mix of stability and flexibility when it came to changing the heels,” Cabe said. “We had to provide enough resistance that the heels would stay on during regular wear, but not so much that they couldn't be taken off easily. They also had to withstand issues like being caught in grates or between cobblestones—just like a traditional shoe.
SolidWorks software allowed the engineers to learn the torque effect applied by someone standing, moving her feet, dancing or just walking.
Interns from top Massachusetts schools, working with a design firm, to design and prototype the products. The heels then will be manufactured by injection molding and shipped to shoemakers.
