Optimal Device: Using Tosca to Design for Different Manufacturing Processes

Rob Stupplebeen’s company name, Optimal Device, reflects his enthusiasm for the power of optimization. A longtime Abaqus user whose consulting and training team focuses on medical devices, he has employed SIMULIA’s Isight, Tosca and Simpoe-Mold to help design everything from ballistic face shields for the military to precision optics for space telescopes. He also likes to showcase the occasional “goofy” design just for fun.

“Tosca is as close to magic as you can get with simulation” – Rob Stupplebeen, Optimal Device

A former high-school lacrosse player, and now a coach for his eight-year-old son, Rob recently began a use-case blog about lacrosse-stick head design, which he turned into a paper for the 2016 Science in the Age of Experience event in Boston. Stupplebeen began by comparing the equipment he played with in the past to the sticks in use today. “When looking at my old lacrosse head, I saw noticeable differences between it and the more modern ones,” he says. “It had clearly evolved from my time, as an injection-molded industrial-design with manufacturing constraints, to the current engineering-driven design with a truss structure of varying angles and sizes. This kind of organic truss structure is essentially what topology optimization evolves towards.”

Starting from the NCAA rules regarding stick dimensions, Stupplebeen created a CATIA model of the head component with the largest permissible amount of material. Then he brought the drawing into Abaqus. “Once you have that working FEA model it can include nonlinearities because of Tosca’s unique abilities to handle nonlinear topology optimization,” he says.

Work went quickly, Stupplebeen reports. “From opening up the rule book to having a viable design on-screen only took a couple days and I produced something remarkably similar to recent commercially available injection-molded designs,” he says. “I also was able to do it all on my own. Topology optimization provides a huge amount of power and intuition into a design without a lot of labor at your end.”

Meeting seasonal fashion demand with 3DEXPERIENCE

With its rapidly changing trends and seasonal lines, the apparel industry is one of the most dynamic industries in which a company can operate. But how do apparel manufacturers keep up with shrinking product development cycles? And how do they manage to react to customers’ rapidly changing needs while also meeting their expectations?

LF Corp (LF), a Korea-based company engaged in the manufacture and distribution of men’s and women’s apparel, was facing these very challenges. As Korea’s leader in the fashion industry with over 34 brands such as Hazzys, Maestro and Towngent, LF needed to find a way to deliver a quick response to market demands.

To help meet these challenges, LF adopted Dassault Systèmes 3DEXPERIENCE® platform and its PLM solution for fashion, My Collection. 

My Collection’s Design Library has a strong data management component.  This allows LF to quickly create new products by easily modifying materials or patterns, as well as develop seasonal concepts. The solutions provide users with a single data source which allows people from different disciplines across LF to collaborate and share information such as what raw materials and colors to use in in order to get the seasonal concept right. My Collection also offers a way for LF employees, management, buyers and designers to monitor project status in real time to help make faster decisions. This led to a 60% reduction in days needed to deliver a new seasonal collection.

With strong benefits so far, LF plans to leverage Dassault Systèmes solutions in others ways.  They are developing processes to gain more business insights in order to help to improve their customers’ buying experience.  They also want to synergize collected data to forecast market trends by considering sales data and consumer feedback. And, LF plans to enhance consumers’ online shopping experience with the help of Dassault Systèmes’ 3D simulation technology.

Check out a new video to discover more about how LF is using 3DEXPERIENCE to meet their business goals now and in the future.



Why choice is important in the fashion industry

Making choices makes us feel secure about ourselves. It’s a powerful way to feel in control of our destiny and to define the way we want to live. This is so very true in the Age of Experience where consumers want more than products and services, they want experiences. In the fashion industry, even though new styles are invented every season, brands need to remember that consumers want to express their individuality by adapting a style to their tastes and objectives. Brands that provide their consumers with stellar experiences are those that have already gone through the process of shaking up the status quo by asking themselves a whole new set of questions about what their consumers want. And the answer they came up with is choice.

Consumers already have choice with respect to where they want to shop – on line, in a physical store, or both. Yes! More and more, retailers are adopting an omni-channel approach and taking advantage of the technology boost of these past few years to multiply ways to provide their consumers with more choice.

Smart phones and tablets are ubiquitous, they accompany us everywhere. Retailers shouldn’t miss the opportunity to take advantage of this technology to reach out to their clients.

Imagine this…A fashionista enters a luxury clothing store in Paris. She asks the salesperson to show her the brand’s new line of beachwear. The bathing suit she’s presented with is nice but the color is all wrong. She asks to see it in black. Unfortunately it’s not available in the store. There are two ways this can pan out: either the salesperson tells her client it’s not in stock and misses a sales opportunity or she hands her a tablet displaying the bathing suit and proposes that she choose the color she wants and offer to send the bathing suit to her home.

It doesn’t take a genius to figure out which option is the most consumer and business-friendly.

Using technology, therefore, is an obvious asset. The store was able to meet a wider range of its client’s needs even though the bathing suit was not physically available on premise. The salesperson was still able to showcase her entire assortment and improve the buying experience without inventory burdens. She secured her client’s loyalty by offering her a wider range of options (shown in digital form) and proposing a solution (“yes, we have the black bathing suit and we can send it to your home”).

However, not all technology is equal. Putting a tablet in someone’s hands is efficient only if the app is powerful and easy to use. The bathing suit images need to be of top quality and true to life to generate excitement. Intuitive navigation is crucial to avoid frustration when the client applies new colors, materials or adds accessories to imagine the total look before making a purchase decision.
