“Alexa, how will my design perform in the real world?” Too bad prototyping isn’t that easy. You can apply your most complicated formulas, you can run digital simulation studies all day, but it will not tell you how an individual product is actually performing in the real world.
With advances in Internet of Things (IoT) technologies, it’s now practical to add and connect sensors to both the digital model and the physical product. This effectively creates a digital twin using Creo; that is, a digital representation of a physical experience of an actual product.
The physical sensors stream data back to the digital model—telling you exactly what’s going well and what might need some tweaking.
Sensor-enabled products and design may sound like a curiosity. But in fact, some companies already use the technology to help develop products—especially those that can easily adapt to new ideas.
Case in point? A lightweight (just under 1000 pounds with a driver) single seater vehicle designed in Israel.
“Because there is no motorsport industry here it means we are not confined by any kind of dogma or certain ways of thinking that tells you a racecar should look like this, or should be operated like that,” said the company's CEO. “We have no culture behind us; and so we can think outside of the box very easily.”
That helps explain why the company became early adopters of the digital twin approach to product development.
PTC Senior Vice President, CAD Segment, Brian Thompson picks up the story from there. In a recent presentation at Develop3D Live 2018, he explained: “The company was having trouble translating shock absorber deflection data into real insights into how the car was performing as it went around the track.”
The company added sensors to the physical racecar (and, correspondingly, to its digital model). Creo Product Insight Extension then streamed real-world sensor data back to the digital model as the car lapped the track.
“As soon as we piped that data into a digital twin of the car and had the CAD model calculate the actual physical reaction of the car and its shock absorbers, they immediately saw a problem in the front suspension,” Thompson said. “The car’s performance improved immediately.”
Of course, you can apply some sensors to and gather data from almost anything. But, to best apply it to your design, you’ll need to connect the data streams to a digital twin.
Here’s a closer look at the process:
To summarize, you’re building sensors in your models that connect to sensors in the real world. Then, you’re using real-world data to run simulations in Creo. And note that while this example looks at a prototype, there’s no reason you couldn’t do something similar with your products released to the field.
