What if our ability to imagine a world for consumers made richer and more productive with connected devices was limited by the imaginations of the engineers chartered with building them? What if how we’re conceiving of these things is one of the very things holding them back from arrival on the market?

Michael Rayfield, GM of nVidia’s mobile business unit, showed me a prototype Anywhere Device last week that his firm built to showcase its Tegra computer-on-a-chip family–a potential core component in an entertainment-focused device. What I learned reminded me that the way you ask a question at the outset of any undertaking has a huge influence on the nature of the answer.

“One of the problems with the mobile internet devices out now such as the Eee PC is battery life. That’s because engineers seem to approach the design challenge by taking a conventional x86 PC design and saying, ‘How will we cut back the thing’s power requirements?’ nVidia decided we could help the industry by creating a sample pocket-sized mobile device that could be really useful for 24 hours without a recharge. We think that’s key to a successful consumer experience. To do that, our design process started with a zero power budget.”

I did the expected double-take with that remark. To design a power-miserly device, they decided to allocate no power? “Not far from it,” Michael said. “What we said was, nothing gets power in the design until it’s been proven that it’s needed.”

I thought suddenly of NASA’s Apollo 13 mission, the so called “successful failure,” when following the initial crisis, grounded crew member Ken Mattingly (left in the NASA photo above, next to mission capcom Joe Kerwin) was tasked with figuring out how the crew would re-start the command module without exceeding the limits of the reduced power available. In the film version of events, after many attempts based on removing steps from the power-up sequence, he finally realized he needed to start over — to design a brand-new power-up sequence that didn’t cause the system to overload the available power.  Only then did they manage to address the severity of the limitations. 

It’s a compelling dramatic moment in the film. More importantly, it’s a reminder that a zero-based approach to anything ensures you take nothing for granted. In the case of nVidia’s zero-based power budget, the thought exercise worked in spades. The device that Rayfield’s team built serves up gorgeous high-resolution graphics, multi-tasks like crazy, and runs forever.

Just as the technology industry suffers from blind incrementalism–as in, what other new slick thing can we add to this product–it also suffers from, shall we say, decrementalism. Why do we like the iPhone so much? One reason may be this: its designers didn’t aim to out-do the smart mobile phone category, but rather to come up with the best hand-held device they could make, starting from a clean sheet of paper.

I’m sure some 2009-2010 connected devices will benefit from nVidia’s power re-think. The real question is, what false assumptions have we been making about what needs to be in a connected device? What zero-based rethink can we do on function?
