- This is the beginning of a video series about multiple automation machines. It is called "the modular production system"
We start with modules that I build using 3d printing to count and package screws.
In each video we will go through the development.

I would love to hear more about complexity shifting theory 😊
same i think it would be a very interesting video
me too
Me too!
yup gimme more of that! the way he described it, reminded me of programming. variables, functions and nesting all apply
Me too 😊
More videos on whatever ! I could listen to you explain these systems and your design philosophy all day long. I just found your channel and cannot wait to binge watch everything.
Agree 💯
4:11 - just giving the concept a name, "complexity shifting", already gives my brain something to latch onto as a way to think about ways to solve problems. I love it. Is it a phrase you've heard elsewhere, or entirely your own invention? Either way, I'd be interested in hearing more of your thoughts about it! And I expect I'll be pondering it either way. Indeed, I think I already have been in ways, without having a name for what I was doing, and thus thinking about it a little differently, but I think the thoughts were in that realm in a way.
I think you use this complexity shifting all the time when you design assemblies that use standardized parts like screw, zip-ties etc . The part that holds everything together and that is regularly produced on the mill contains all the specialties necessary to combine functions to work together in the designated way.
I totally agree with you idea of complexity in 3d printed parts. The technology of additive manufacturing makes the realisation of complex / feature rich geometry easy and we should utilize that in our designs. On the other hand big or many printed parts make this manufacturing process more complex (time consuming / costly) itself thus reducing number and size of these parts while / by maintaining a high "complexity density" is the best utilisation of this technology I think. Using of the shelf parts for the rest of the assembly's is just reasonable.
Complex*
Also, wear/durability of the parts could be considered, depending on the application. If a part fulfills a lot of functions and one function fails, you would have to replace the whole thing. It might be worth it to produce a seperate part that can be easily replaced, or make it out of a more durable material.
@@Frrk Yeah, this is of cause true, but only to some degree I think. If I have a system and would design it such that every (printed) part has only one functionality to it, I'd have to disassemble more of said system to replace different parts. If the complexity lies only within some parts (that thus have multiple functions) and some functionalities fail, I would have to replace and disassemble less of the overall system. Especially if these few spats are easily accessable. And the production of feature-rich parts is with 3D printing probably as easy as it gets. So, as always, it depends on the case of cause, but my point is that even when thinking about failing parts, grouped functionalities might not always be a bad thing.
@@jannsander This also has a cost factor attached to it. I see it a lot on cars, one part does 5 things, and when it breaks it costs an arm and a leg.
It should be a balance between the two.
@@AlanGonzalez-om4rr That is absolutely true for cars and airplanes and other insanely expensive stuff, but for 3D printed parts I think there isn't so much of a problem there - of cause referring to the restrictions above.
Complexity shifting -- YES, please! I'm a lifelong engineer (software, systems, manufacturing) and now retired, helping EE and CE seniors with their capstone Senior Design Projects. The concept of complexity shifting is hugely important in optimization, but it is generally done intuitively, and mostly unconsciously. I'd love to see someone (you?) formalize and expand on this concept. Thank you for making me aware of it -- it's a revelation.
love seeing the progress on this, great implementation! 👏
Love the CAD section view overlay when you explain the functions! Also would love to hear more about complexity shifting
Complexity shifting is a great concept, that any experienced 3D printing designer knows in a blurry way. You named it and gave it a brief definition. I'd love to hear you about this.
Complexity shifting seems like a good topic, keep it up !
Yeah, super interessante Gedanken, die Du da entwickelst und in die Tat umsetzt, tolles Niveau, danke für's Teilen!
I wasn't expecting to be this hyped about this series when I subscribed but I am hooked.
Brilliant! I've been making and 3d printing for over a decade, yet in a few minutes my outlook in 3d printing for industry has changed completely!
danke, deine ansätze finde ich großartig und vielen dank fürs teilen
Waw, what an amazing channel you have! Really cool and excellent work!
Thank you Christopher, I'm loving this. More please. I dream of auto feeding small parts onto small machines.
I don't know if you know this, but you just reinvented the vacuum feeder. Pneumatic conveyors are pretty common in injection molding facilities. It is great to see a young engineer at work. I wish I had the tools we have now when I started out. I also like you discussing "complexity shifting". I wish more engineers worked harder to improve the manufacturability of their designs. I see so many instances of thousands of dollars being wasted just because a guy at a cad station decided that's how a part has to be.
I am interested in anything you are doing. Keep making this quality content!!! The quality of your machines is easy to see. Most people who haven't 3d printed will not understand how many iterations it takes to make a system that functions as well as yours does. A true masterpiece!
Id be interested in a video about your take about complexity shifting.
Wunderbar gelöst. Es freut mich einem jungen Genie etwas auf die Finger schauen zu dürfen. Tolle Videos, weiter so!
I have worked on similar pneumatic hardware feeder systems in the past. They were able to reliably feed through over 10 meters of tubing. They used a small tube mounted though-beam sensor that detected when the screw dropped into the feed tube and used that to trigger the air blast. Worked very well. They also utilized a 1 into 4 mechanism where one bowl feeder was able to feed into four separate output tubes that were selectible via pneumatically actuated gates. Additionally it used a profile image sensor to verify correct hardware length and diameter at the bowl output chute before releasing into the pneumatic feeder stage.
That is some really cool content! Thanks for sharing, it is great to watch your videos. Keep it up!
It's late and I really should be sleeping. Instead, I am now following your journey of design and automation.
I am on a FIRST Robotics team, and I think the idea of complexity shifting could really help us out if we knew more about it, so a whole video would be great! I’m also interested in the counting system you show at the beginning of each video, and some of the design process of that would be great!
Check out the previous 3 videos in this series if you haven't already.
@@Convolutedtubules I saw the other three, but I would like to know more about the thing he dumps the box of screws into that then orients them and gets them into the whole counting system
great work, i like the complexity shifting theory, and the idea of using the power of 3d printing to make functionally dense modules. Weiter so!
I think you are absolutely on to something with this "complexity shifting", maybe also in relation to the "failure probability when combining things" you are talking about later in your video. Startet following you. I think you have a very clean and scientific approach that I like.
Great content I love this kind of going down the rabbit hole videos. Thank you for sharing your creator mindset with us!
Wow what a fun project and I love that the sorting machine fits into that storage box and stacks nicely. Amazing designs.
Oh man nerf actually taught me a lot more than I thought. This is very similar to RSCB and Inline systems used in hobby blasters since the 00's
You're an absolutely brilliant engineer
really like how your designing manufacturing processes around 3d-printing, look forward to future videos
AMAZING DESIGN! Keep the quality engineering coming!
I like how calm your videos are, its a nice change of pace.
I just finished my last year of engineering and I can tell you that the idea of complexity shifting was very important in making our capstone project work.
You got recommended to me by the almighty algorithm, and I’m hooked! I’d love to hear more about complexity shifting!
you are good creator, I was amazed by this. Thank you for showing us a glimpse of your creation
I would love to hear more about complexity shifting! I love your videos and the way you approach engineering and design.
I love this channel. Keep it up!
Industrial automated screw feeders that feed auto screw drivers usually have a 24v DC extended field proximity sensor to count the screws passing through the tube and trigger the valve, ensuring only one screw travels per cycle and the system does not get blocked up with hundreds of screws
I love the concept of shifting complexity, most of my life I've been into repairing stuff, not so much creating it, and have noticed this in almost all products, be it computer mice, kitchen blender, or even a car. I also personally have been taught that principle, although without calling it specifically what the author of the video does, in my production automation degree classes. Most of the time, I believe, it's caused by some kind of limitation in manufacturing (mostly money), but giving it a name is still very powerful for analyzing new designs.
Your explanations are really great, Please continue.
I have been loving this content. Very different and very interesting for anyone interested in engineering.
I agree with you on shifting complexity!
Very nice project, It's always a pleasure to find people that make such great stuff. You definitely should have more than 23k subscribers.
You're killing it man
I love that someone with a large following is saying this about 3D printing and complexity. Too many times on youtube I see some maker get a 3DPrinter, then start printing simple round obects, large flat plates, etc.
yeah, I would suspect that most people with 3D printers aren't really designers / skilled modelers. but even for those who are: we're coming out of an old school era of design tools being built around sheet metal bending + milling operations, so we're also still just now emerging at a CAD level to even draw up the complex geometry that printers can print
The channel kames bruton os the worst offender when it comes to this
I worked in the 3D printing lab for my university for a bit and the amount of graduate and masters level engineering students requesting square-ish blocks with a few holes in it was astounding.
Flat plates with holes.. when we had laser cutting lab
Loving the videos! Keep them coming!
Definitely watching all of your other videos right away
Yes, please do a vid about complexity shifting! :D
Awesome work! :)
Great videos. Keep them coming!
Very cool. I'd love to hear more of your thoughts about complexity shifting. It sounds very interesting.
Great video! I love the work you put into this!
Fantastic video always.
Ok this is one cool channel =D, very interesting 3d printing applications. Thanks for sharing, looking forward to the screwdriver application as well!
Cant wait to see all the different modular parts in the future
This is awesome
Genius. Great videos. Thanks.
Great to see your post.
I agree with you on complexity shifting! I've thought about this stuff a lot but haven't been able to put it into words like you have. Moving complexity to manufacturing technologies which do well with complex geometry at low cost, like 3D printing, laser cutting, waterjetting, and then relying on simple off-the-shelf components like 2020 extrusions for the rest can result in a very cost-effective design that still meets the requirements on the design.
Another area I've had success with is with moving complex wiring jobs onto PCBs. PCBs are cheap; $5 + 1 hour of soldering will in the end be a lot better than $0 of PCB + 10 hours of wiring. Good for robots and cars.
Love the design! So many clever ideas.
It might be a cool idea to make the re-orienter "slot into" the accelerator so that if you make re-orienters for different screws/parts you can just swap out the one part and all the hoses can be left where they are.
Very nice work sir. Complexity shifting is a great concept and I would love to hear more of your thoughts on it.
I personlly would love a video highlighting your design process, as well as going more in depth on complexity shifting. I am just getting started at designing my own parts and assemblies and your videos are great for seeing the process behind how you iterate and create.
The topic of complexity shifting should be a class in itself in within design theory.more please!
Man I love your vids, keep it up 👍 I think you are passionate in what you are doing
I would be very interested in hearing more on your ideas around complexity shifting!
Complexity shifting sounds very interesting!
Very cool and impressive 👍
Nice, I think this will be my next favourite channel...👍
Fascinating…. This earned a subscription from me and I want to learn more. 👍😎👍
What a great first video introducing me to your channel, liked and subscribed! A dedicated complexity shifting video would be a great watch! I've never come across the term and sounds like something even just the principles of could be beneficial to know and understand.
Nice solution !!!
For efficiency, you could add a small solenoid valve for the compressed air and a hall effect sensor right after the spot where the two channels meet, which would open the valve through a transistor each time a bolt passes it.
I had a similar idea for keeping the valve open until the bolt is at the end of the tube, so that the tube length does not matter - but i'd go with an optical sensor, as not all bolts are necessarily ferrous. ;-)
@@jangrewe you’re right! Optical sensor is certainly a better idea for then you don’t have to worry about the type of material at all.
Yes please, go on about reducing complexity! Been thinking for too long along the same lines, want to hear your take
We use this style of system to feed nuts, bolts, and studs to our robots at work. We run them out about 20 meters at .6bar with no real issues on leakage even though our feeder is not airtight. We have a sensor inside the effector tooling that sees when the product has arrived before shutting the solenoid valve.
Complexity shifting from your perspective would be fascinating to hear more about
Hi Christopher. This was a very interesting and inspiring video! New subscriber from Australia!✊
Very well explained
Another module that would be cool to see with this system would be a tube multiplexer. Perhaps using a stepper and linear motion connected to a sliding manifold to switch one screw output quickly between many tubes. Might be able to expand the capabilities of a single feeder/counter system to an array of end effectors, especially considering the rapid throughput would in many instances be able to accomodate a large array of end effectors if their fills/minute are as low as the current system for 3D printing. One system could easily support a very large farm at that rate.
Genius with big ideas keep it up❤
i wait for every single video you make. so if it will be about complexity - no problem
Waiting 4 more !!!
Good video, well spoken and presented, well done 👊👍🙂
The basic principle in manufacturing is: If some components break, how fast can l fix or replace the part which is the reason why Toyota took over the market from Landrover in Australia and Africa.
I am about to graduate as a Mechanical Engineer, and would love to hear about how you do complexity shifting. Great stuff coming out of your channel, I hope to see more! no pressure on timing though
yes please more about complexity shifting!
Amazing!
I would love a video exploring your complexity shifting ideas, and the idea you touched on - your personal opinion as to what hierarchy to do this between different design modalities - electrical, mechanical etc . Do please ! I find theoretical abstractions like this really interesting to help guide my thoughts ..
my guy ur a GENIUS.
Just keep doing what you're doing and all will be well! :D
Please continue posting this videos !
Complexity shifting sounds fascinating.
elegant solution
Ich liebe deine videos einfach!
4:11 - Yes! I find abstract high level engineering considerations super interesting.
I'm working on my RepRec & ReChain projects (some info on these on the RepRap wiki and links from there). My problem space constraints led me to some quite unusual set of high level design constraints there.
Likely already mentioned in the comments but you could easily add a limit switch within the accelerator assembly to trigger the air only once the part has passed the accelerator part. It could also easily be used as part of the counting mechanism too for confirmation.
... or a photoelectric switch
I vote for a complexity shifting video as well. I'm a programmer by day and I feel like the ideas would be useful for my line of work.
This is really smart.
Yes, please cover complexity shifting in another video!
I am really interested in your ideas about complexity shifting. Please say more. And I love seeing what you produce.
good content!
this is so cool
its the first 3D Printed Particle Accelerator!
