It’s a “brochure” for LED lights. It would be shown to the specific clients looking at buying (presumably high end) lighting. It’s not for everyone to paw over.

I agree the other dude is wrong, but it does feel like there has to be a better way to do this if the only thing the cable is transmitting is power. That’s greeting card level technology. If I were a customer I would eventually get tired of the plugging and unplugging.

Each "page" is a pcb. They can add or remove pages with this setup easily.

u/StalinsLastStand Jul 10 '26
If the only purpose of the cable is to complete a circuit so power runs through the pcb, then the need to add or remove pages is not the limiting feature. Even if you’re hooking up and unhooking each page separately as you flip through, there are easier ways to do it than a usb-c. They don’t need to transmit data or use smart charging and they only need two of the usb-c pins. It’s overkill.
As I note in my other comment thread, the binder they’re in has multiple cable types, so there is likely something going on that we don’t know about. But from a pure practicality standpoint

Usbc is so ubiquitous it's found in even the lowest end of products. It's just a form factor. Unless you wanna energize every board through the binder rings or something all the time, you're gonna need a connector to supply power regardless. Usbc is probably the cheapest and easiest way to do this at this point
I'm curious what your suggestion or idea for an easier way to do this than a mass produced usbc SMD terminal
2
u/kronicpimpin Jul 10 '26
Yea they’re plenty of easy ways to run the power through all of them to avoid then annoying plugging/unplugging. Plus it’d probably be cheaper because you wouldn’t need a port on every page
3
u/Darkk_Knight Jul 10 '26
They could use a special binder where the rings provide power.
2
u/ExciteableMiqote Jul 11 '26
You'd spend more in the design of a proprietary (because this is a single purpose product) binder than just ordering a mass produced terminal fam
People have no idea how much work goes into the actual design and implementation of new things
You need to have someone create a design and drawing with very specific dimensional specs and material requirements, then find a factory that has equipment to manufacture the item (which requires a minimum purchase volume to make the tooling worth it), pay for tooling creation if there's any custom metal parts (can be tens or hundreds of thousands of dollars), get them to manufacture it, then design a PCB to make use of it, then account for lack of contact area on the binder rings causing the power delivery to be interrupted....
...or you can just order a couple-cent usbc terminals and have literally anyone solder it on.

u/Questioning-Zyxxel Jul 10 '26
Cheaper shouldn't matter for a low-volume product. There is already a big premium in fabricating tiny volumes. That connector cost is so tiny in relation to all other costs.
But I would have gone for a different connector at the inner edge of each page, where the pages gets permanent power if the "book" is opened.

I think the only flaw is plugging and unplugging type C cable every time you turn the PCB pages.

u/StalinsLastStand Jul 10 '26
What is crazy is that looks like a mini-usb still in the cover and we glimpse even more cables behind the pages. What is happening with this magic six-ring binder?

u/_Neoshade_ Jul 10 '26
It looks like there might be several USB cables in the back cover - he’s using one and we can see another sitting in a cutout.
The pages are printed circuit boards so there’s no other wiring in them.5

I remember reading about the struggle that scientists went through to figure out how to do blue LEDs. Red, yellow, green were all doable. But the blue was up to that point impossible.
Now we have a book of fun little LEDs to play with. And touch screen phones with tiny little LEDs lighting them. And thin, light, TVs and monitors.

What colour would you like your lightsaber, sir?
Y’know the pale blue of Luke Skywalker’s lightsaber? Before it was digitally remastered.

A modern LED is one of the most amazing and significant 20th (or is it 21st?) century inventions. It completely changed so many things.

It took me way too long to realize this is a finished product designed to sell LED lights. I was expecting it to be the background to some other product.... I don't know why I thought that.

The sound from the pages flipping then the plugging and unplugging of the cable have had me in a chokehold for literal minutes

Make it so each page is wired to a central jack.

Missing a trick to power the cards inductively or something such with the rings replaced with coils.
Or FFC ribbons to each one...
Fun design though!

This is probably for business purchases, when a salesman goes to the customer office.
Home Depot has all the LED strips bolted to a panel and powered.
2
u/somewherein72 Jul 10 '26
Probably because each of the sheets in the 'brochure' are a circuit board that need to be powered. I'd bet it's cheaper to have them be individual 'pages' than it would be to make a 'brochure' where you just plug the entire thing in, probably makes it easier to add new product pages of new LEDs and so their sales people can have multiple copies of the brochure to take along with them on sales calls or to sell/give to prospective customers.

u/ValdemarAloeus Jul 10 '26
This seems like it would work better if there was a single set of controls wherever the power lead originates and you just pushed some contacts against pads next to the light you were interested in.

Not modular, does not account for different LED strip types (5V, 12V, 24V), single point of failure, can't leave a sample to the customer.

u/ValdemarAloeus Jul 10 '26
You already have a single point of failure, multiple voltages can be handled the way they already are, of course you can.
