@CJ-rl4kd is it not you basically do the same thing it's just a little different like hardware development is science and its also considered engineering no? And how deos that pin work anyway deos the foil tighten up when it's pressed down or get compressed like a pipe on a hydrologic press
@@dreadaby engineering is purely physics (which still is science don't get me wrong) but IG what CJ meant with "science" is chemistry EDIT: MECHANICAL engineering is physics, made a mistake there
I mean, most PhDs are like this anyway, extremely narrow subject that has probably limited uses but it's very deep. The value comes from being able to make such a deep and complex work.
It’s important for anywhere that hollow or lightweight supports are needed, such as buildings, aircraft, spacecraft, and underwater pipes. It’s difficult to design something precisely if you don’t know when or how it will start to collapse and fold.
@@spe.z.artist the metallic covering is a metallic ,plastic foil( like modern sweet cover). Underneath this sheath of foil the true pen/pencil holder is plastic that has been manufactured in the geometric shape you can see when the pen/pencil is compressed slightly. Compress and the foil (attached to the plastic only in certain areas) takes on the shape of the plastic. Elongate and the foil is stretch out again, becoming smooth Clever design engineering ❤
The pen mechanic: To crush: Easy. It just pushes the pen cover/outer layer with [so much] force that it crushes or crumples the layer. The straightening/ uncrushing: Super duper easy! Even easier than the crushing! It just pulls it with force So that it gets straightened!
Everyone is disappointed that it’s just thin plastic being stretched over a pre-shaped pen shaft, and not shape shifting metal, but the fact that they were able to so effectively deceive everyone is impressive in its own.
Actually, a metallic sheet material called Mylar bends pretty similarly to the design on the pen. My guess is that the plastic is just a guide for the sheet to bend perfectly into the grooves.
To be fair, if I was attacking someone and saw them pull out this pen from their pocket I'd probably get very distracted by it and be very vulnerable while playing with it
He's right to be disappointed; I looked into this morning and it's marketed more as art than anything. The pen isn't even rated to be switched back and forth many times before it fails.
@@danielbush6882 Initially it wasn't even refillable but he's since made it refillable. The name of it is Crushmetric SwitchPen, the guy has a video here on youtube explaining it.
@@minamihasaki4325 I'm sure they still work fine-I don't mean they won't be able to write anymore, I'm just talking about the structural integrity of the sleeve; the artist who created the pen himself stated that it wasn't meant to last long, and was more of an art piece you can write with.
This makes up for the disappointment felt at the end when he expected it to be a lot more complicated, who is the guy who created that pen so I may see his other works?
He probably just drop ships, although he claims he invented it....a similar pen was sold when I was a kid so I know for sure he didn't invent the idea at least.
The physics behind is relatively simple, the metal sheet undergoes elastic deformation as a result of compression and its deformation according to the mold’s shape. I made something similar for a project while doing my bachelors but that was more related to machines for manufacturing where you could change the mold out under it and compress it to your need.
“Theres actually been scientific research on the folding of thin walled shapes!” Sir, are you gonna order something or not? “Do you wanna come to my house and see what happens when you crush a baconator in my hydraulic press?!😀” Sir, im not one to kink-shame others….but this is a family-friendly Business so I'm gonna need you to leave the premises.
I have a deep hatred for that specific pen because I would receive literally like a hundred youtube shorts promoting it from bot accounts, and I must avoid funding them at all costs.
@@placeholder3863 I mean, on one hand yes, but on the other it's a $10 pen that was made refillable only after backlash got too big. And then, the way it was first presented by the artist, and the way it works are two different things. I think he even deleted the original video since I can't find it. There are only a couple of shorts surviving.
I remember someone was advertising these pens as some sort of "practical, everyday carry piece of art by some renowned architect" while in reality it's just a novelty pen
The stuff is Mylar -- polyester sheet with a very thin layer of aluminium. The same thing they use for packets of crisps/potato chips (the inside of packets are mirrored!)
I did an aerospace engineering degree and this is the principal of buckling of a thin walled cylinder, however the reason there is the plastic profile below is to support the buckled shape. Otherwise you wouldn’t be able to hold the pen without deforming the pattern. Our Structures lecturer was so happy to show us this pen and talk about the principal behind it!
It has an outer plastic shell, which would support the structure of the pen and allow it to be held. Aerospace engineering degree sounds like it’s really paying off.
@@BeforeThisNovember have this exact same pen, there is no outer shell. You hold it by the crinkled middle section which is supported by the molded plastic cylinder underneath.
On a more serious note, people should appreciate that something that looks beautiful can be made so simply and elegantly. You do not need a complex solution to create something amazing
So it's just wedging the two pieces on the inside together when you slide the "button" down. Expanding the inside from the opposing vertical slants where the two center pieces come in contact in the middle.
Thank you! This is exactly the type of detailed explanation I was expecting to hear in the actual video! (So disappointed to not get any explanation there.)
@@aliveandwell3958 I searched the internet and someone on Reddit said that there is a loose sheet of metallic plastic over a stiff material with holes designed in it. When the pen is clicked, there is a suction applied to the foil that makes it “grip” and accept the shape of the stiff material with the holes in it. That was probably confusing 😶
I was expecting the shiny outside to be a thin metal sheet with scores on the inside so when crushed it crumpled in a predictable and predefined way, like how if you fold a piece of paper and make a crease, it will then fold along that crease very easily.
@@Pabloesc571 Well, it’s clearly not just store bought aluminum foil. Look at the way it returns to its original smoothness with no creases or blemishes at all. The metallic finish is most likely a mylar coating which is pasted atop a thin sheet of polyester, resulting in the finished tube when rolled.
