Someone Designed A Brilliant Food Cart That Doesn't Block Airplane Aisles

The design does make sense but I do see some potential drawbacks. First off the pressure shelves are obviously spring loaded (similar to a paper napkin dispenser) and springs can break or get worn out from use and what good is such a system when the spring breaks thousands of miles from your destination. Secondly, I doubt airlines are going to want to install a special track into the aisle for these carts (although I do think that it's an interesting way to deal with the turbulence in flight). and a motorized cart just seems lazy. I think that the motorized elements plus the sunken track will likely result in additional weight over traditional carts. A thinner cart makes absolute sense as the current designs really have a lot wasted space and are not designed for the way many airlines do inflight service these days plus take up space not just in the aisle during service, but also space in the galley. The basic design could most certainly work as a wheeled cart, but some of the other elements may be a bit more than what an airline would be willing to do. If these cart could reduce the size of airplane galleys on an a/c or reduce the number of galleys needs on an a/c, airlines could potentially add more seats to maximum revenue on flights.

Very interesting design.

But it is a complete redesign of not only the cart but the meal packages, the beverage packaging - and requires modifications of the aircraft floor.

At least someone is thinking. We might see something like this on a new build aircraft.

While it is smaller, it really will not work. Your typical narrowbody has an aisle width of ~20" (obviously depends on the seating). Considering this is 8" wide, that leaves you with only ~12" to play. Put it in the middle as shown and that is only 6" a side, not enough for someone (especially a larger person) to comfortably slip by without making things real awkward for the person sitting in the aisle seat. You could move the cart over to one side, but you are still only realistically looking at 10-11" of space, which is still a tight squeeze.

Considering all the additional costs for this idea is it really worth it? I'd say no.

Quoting srbmod (Thread starter):

With such a tall, narrow and (presumably) heavy cart, the first thing that comes to my mind is the incredible torque that will be imposed on the track about the plane's longitudinal axis. Those things would have to be pretty strong.

But yes - as Polot said, it doesn't really seem like this will solve the problem of getting around the cart in the aisle. There's just not enough clearance.

Interesting concept and design but may only be suitable for aircraft operating short haul. It would certainly appeal to LCCs offering BOB of the takeaway type. But on an 11 hour flight where meals typically include fruit, salad, bread roll, a hot main course, cheese and biscuits, a cup of water and/or juice, the meals would not fit into the small box required.

From a cabin crew point of view, it appears more ergonomic in serving meals and would reduce strains caused by kneeling up and down placing trays into a cart. But how does it perform with reloading all the used boxes and waste after the meals service?

The track would not only provide stability during turbulence but would prevent the cart being tipped as a (dreadful euphemism alert) person of size attempts to squeeze past. Eight inches width is quite a small foot print, especially as in the diagram the cart would appear to be longer than the standard carts in use. As meals were unloaded the cart may become top heavy, increasing instability. If the cart is longer, how much space would actually be saved?

One question. What about all the coffee stirrers, packets of sugar, pieces of plastic etc that will accumulate in the track?

Why not just make a conventional cart about half the width, and keep the design, well, conventional?    I know it would be prone to tipping over outside the confines of an aircraft aisle, but at least in the aisle if it tips, it would be stabilized by the seats...

And then the hot coffee winds up all over grandma and then she sues...

Possibility...  

On the Design....I quite like it.....However what about the reliability of the unit...In case of a breakdown of the mechanism....



Think of the brighter side!

The floor structure rework makes this a non-starter.

On any aircraft that has floor panels sitting nearly directly on the floor beams, this would require cutting into the upper chord of nearly every floor beam.

While that likely could be accomplished for a price, it would make for some significant weight gain and a few wealthy stress engineers.

Which lead me to think . . .

How about a Full/Half height cart that hangs from rails on the ceiling.

This way, you can have full width cart and instead of going around the cart, you go under the cart.

You don't have to modify the floor which are structural and is controlled by the Aircraft OEM.

The overhead ceiling is less structural and can be modified by a post production shop.
