Hello, and welcome to the Product Design Show. I’m Allison Toepperwein. And I’m Vince Penman. This week we’re looking
at modern implementations of that classic hydraulic engineering device,
the Archimedes screw. An Archimedes screw has many uses, but was most commonly used throughout history to move
water uphill. As someone turned the crank manually,
the screw blades forced water upwards along the threading and thereby transport water
uphill. Once the water reaches the top, the screw design releases
the water into a trough. The device itself is a simple design, it
is a screw inside a tube, but this simple device has been refined over time
and even today it appears in many modern devices. To design an effective screw pump device,
designers typically have to work with a number of fixed external constraints including the radius
of the screws outer cylinder, the total length from the bottom to the top and the slope
of the screw pump. And the occasional girly-man villager
with wimpy arms that can’t pump the water up the hill. The design challenge then is to come up with the most
efficient internal parameters, including the radius of the screw’s inner cylinder, the pitch
of each blade, and the number of blades to lift the water. Optimizing these parameters takes some serious
algorithms and some seriously smart engineers. The design challenges mount when you consider
more mundane design constraints such as cost and manufacturability. And when you consider moving contents other than
water. Designers have overcome these constraints to insert screw
pumps into all sorts of devices, from snow blowers to truck loaders to materials handling applications. Heck, I think it’d be awesome to make a screw pump nacho
cheese delivery system right into my mouth. Take that, stupid chocolate fountain. That’s the last time they kick me
out of the restaurant for dunking my head in you. Our last story comes from a group of engineers
at Van Beek in the Netherlands. They design screw conveyors that get installed
into modern assembly lines. They deliver thousands of screw conveyors,
each year that move everything from food and chemicals to pharmaceuticals and synthetics,
and all of these machines are made to order. That means that every one
of the design constraints we talked about earlier has to be optimized for each machine. Worse yet, the assembly line dimensions,
the given constraints, often change after the screw conveyor design has been started. To meet this challenge,
the Van Beek engineering team uses Creo Elements Direct Modeling software to make multiple fast design iterations to produce top
quality screw conveyors as fast as possible. It’s a lot easier and a lot more accurate than doing
math. You can try Creo Elements Direct,
the same software that engineers use at Van Beek with a free for lifetime version from PTC,
just go to ptc.com/go/modelingpe. That’s it for the product design show this week. If you like the show, please give it a like on Facebook,

    @YousefAB I can't speak for them, but I find that it's not a bad transition.
    For the record, six times in nearly four minutes, and that's only if you count the opening and closing credits, is hardly every two seconds…

    wow.. why not lift water without bypass by welding the screw sections to the inside and outside tube.. the entire assembly will then be much more efficient .  it could reduce power consumption needed to lift water in california aquaducts by 95% where they are only lifting water 30 to 100 feet . as long as the entry point is not totally submerged so only 35 to 40% of the screw is filled.. it won't flow over like a siphon .  easily replaced screw into the sections vacuum breaks could also be installed. also.. so water could not leak out when the vacuum break is below the water level. but when its above it could let air in.. either a flapper or a ball in a cage could be used..

    This is an Archimedes screw. Use PTC Creo. The End.

    Great video but I wish you would have at least shown one archimedes screw in operation.

    It's popularly called an Archimedes screw, but it may have been in use a few centuries before Archimedes was born, to irrigate the garden at Sennacherib's palace in Nineveh in the 7th century BC.

    Should have used Archimedes screw to pump up their brain
