The level of testing needed to bear out these design changes wouldn't have been possible without an integrated CAD and CAE platform, according to Wiersema. "By using the computer to do a lot of the door designs, we were able to filter out the ones that were bad, then take the right one and try it in reality to prove out the concept," he said.
It also enabled the group to explore more design concepts than they had traditionally done when subbing out simulation work to third parties, mostly because they were able to retain their intellectual capital. "When you're working in a single, integrated environment, there's so much knowledge of the tools and the materials behavior that you can actually make something more efficient and have insight into what exactly is happening," Wiersema said.
While integrated simulation isn't necessarily taking time out of Donkervoort's development timeline, it is significantly cutting back on the number of physical prototypes that need to be built, and it is encouraging the engineering team to go further in pushing designs, Wiersema said. "The more time you have, the more you want to develop, and there's no end to how far you can go with the detailed amount of information you can get out of these software analysis tools."
For a look at GM's Chevy Volt, go to the Drive for Innovation site and follow the cross-country journey of EE Life editorial director Brian Fuller. In the trip, sponsored by Avnet Express, Fuller is taking the fire-engine-red Volt to innovation hubs across America, interviewing engineers, entrepreneurs, innovators, and students as he blogs his way across the country.
Good point, Rob. As CAD and CAE become more of an integrated process as opposed to siloed tools done by different groups within engineering, there are bound to be design efficiencies. The real benefit, here, though was upping the number of prototype designs explored without upping the number of physical prototypes having to be built. Time saver and money saver.
Interesting article, Beth. That's a nice way to increase possibilities in design -- to do it with computers instead of physical prototypes. While the process may not have saved design time in this case, I would imagine it would inevitably save time as this practice becomes part of the standard design process.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
The DDV-IP is a two-wheeled self-balancing robot that can deliver cold beverages to thirsty folks on hot summer days. A wireless RF remote enables manual control of the device beyond the act of self-balancing. All of the features of the DDV-IP result in an effective delivery vehicle while providing entertainment to the user.
Eric Doster of iFixit talks about the most surprising aspect of the Microsoft Surface Pro 3 teardown. In a presentation at Medical Design & Manufacturing Midwest, iFixit gave the Surface Pro 3 a score of one (out of a possible 10) for repairability.
