There are many number of cases promising to protect a smartphone from drops, bumps and scrapes, but and idea floated by Honda in a video promoting its new line of small cars adds airbags to the list of potential smartphone protection options.
The Smartphone Case N consists of a series of six small airbags placed around the edges of the smartphone, which are deployed when the case perceives it is being dropped. In the rear of the case is a computer-controlled accelerometer that keeps track of the level of peril to which the smartphone is subjected at any given moment.
The computer is
looking for something like an extended period of free-fall, as when the case is
dropped, the airbags deploy after about 3 ft (90 cm) of falling. (Note: Do not
take this case along when skydiving.) Once the computer triggers
the mechanism, the inflation valve is opened electrically, releasing gas from a
CO2 cartridge into the airbags, which are then fully inflated within 0.2
seconds. When it hits the ground, it bounces around gently for a moment, then
rests unharmed on the airbags. The airbags remain inflated at this point,
however, it is unclear if they can be deflated and repacked, or if each
smartphone rescue would require replacement airbags.
Like everything
else, the Smartphone Case N has pros and cons. On the pro side, it does appear
to perform its basic function effectively, safeguarding the phone. Arguing
against the case is the enormous size, the probable high cost of the case, the
probable high cost of resetting the airbags after use, the lack of protection
if a phone is dropped screen down onto a pointy object, and the danger of
tripping while having the case (or a smaller version thereof) in your pocket.
This may be a concept that isn't quite ready for prime time.
But will it get
there someday? Amazon's Jeff Bezos thinks highly enough of the basic idea that he patented it for Amazon, with Greg Hart as co-inventor. The Amazon patent, filed in February
2010, covers just about any method you might think of for protecting a fragile
thing from drops, including reorienting the thing while it falls, so that it
lands on a less-fragile part, and using air jets to seriously slow the rate of
fall.
If size and cost
can be controlled, together with the danger level for accidental activation,
some such method for protecting smartphones and tablets may well appear on the
market as a boom.
