Day2Night Uses SolidWorks Software to Bring Convertible Heels to Market (FISHER/UNITECH)

FISHER/UNITECH Provides Innovative Shoe Company with Tools to Design a Single Shoe with Multiple Heel Heights

TROY, Mich. USA, September 25, 2012 – Day2Night Convertible Heels, a startup focused on creating shoes with interchangeable heels, is using SolidWorks® 3D design software to bring its product to market faster and at less cost. A 2010 and 2011 MassChallenge finalist funded by Kickstarter, the world's largest funding platform for creative projects, Day2Night is solving the challenge of traveling with multiple pairs of shoes. In the process, Day2Night has dealt with—and overcome—complex design issues, with the help of FISHER/UNITECH, a leading SolidWorks Value Added Reseller

The biggest challenge in designing a shoe with interchangeable heels comes from the need for strength. The shoe must be able to tolerate the wearer’s weight for a variety of heel heights, some of which are intricate and curved, creating potential stability issues. Using SolidWorks software alongside 3D printing capabilities, the engineering team at Day2Night was able to determine the optimal weight bearing load pressure for the shoe. This analysis was critical to learn not only how the heel would hold weight from the top, but how it would react to force when the heels were changed.

“This product required a mix of stability and flexibility when it came to changing the heels,” said Candice Cabe, founder and CEO of Day2Night. “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. Ultimately, we needed to know how much torque effect would be applied for someone to be standing, moving their feet, dancing or just walking. SolidWorks software enabled us to test all of these scenarios and easily develop prototypes so we could create a stable and beautiful product.”

Day2Night is an avid recruiter of interns with mechanical engineering background, giving students from top Massachusetts schools the opportunity to gain hands-on design experience with SolidWorks. These students, as well as a design firm, are helping design and prototype the products with the aid of 3D printing. The heels will then be manufactured using mold injection technology and shipped to shoemakers.

“3D printing is a critical tool for this type of product; it’s essential that designs are tested to make sure they’re safe, sturdy and attractive,” said Jenny Giolas, Regional Technical Manager, FISHER/UNITECH. “Day2Night’s use of SolidWorks to create a one-of-a-kind product and bring it to market is the kind of success story we love to tell; ultimately, designers have the power to make any product a reality using SolidWorks software.”
