The only problem that I see with this idea is similar to the one that's encountered by Genie Excellerator openers. Most installers clip the resistor that enables the 2x opening speed because the door and related hardware ends up wearing out much faster. The rollers on the door, the hinges, etc. would all need to be much heavier to handle the speed involved.
Okay, I have a question. In a real garage door opener, like LiftMaster chain & belt drives, when the motor is inactive the gears lock it down. How would this lock? I don't mean to be rude, but anyone could walk up to it and shove the door open.
Also, the speed of these motors may put too much stress on the top section of door. If you search "Genie Exelerator" these openers open twice as fast and close at normal speeds so they don't knock anyone unconsious.
Here's an idea. Hack an actual garage door opener. It has gears. Change the gear ratios. Voila, a faster garage door opener, but with lower torque however.
Ever see those scissor jack punching boxing gloves at joke shops? Lots of distance for a little amount of motion, but again lots of torque requried.
Nope. My idea would work faster. You only have to move the scissor action a small amount to get a great distance covered. On top of that, nobody has to figure out how to push the door down and suspend a 2nd motor on wheels.
The current garage door opener works well enough, I don't think many people are complaining of it's lack of speed.
The idea is bad. The back motor is moving the weight of the front motor plus the pulleys, plus the weight of the garage door. Another idea, use a scissor jack type of opener. It takes up a lot of space however, but will open the door very fast, as well as close it. The original garage door opener idea is pretty much the most efficient one, and the safest, as it has sensors to stop the door if an object gets in the way.
You have the right idea. Think of a clothes line. The line always stays in a loop, clothes can be brought up or down the line by the direction of pull. If you attached another clothes line to the middle of the existing clothes line, just like your idea, you could retrieve the clothes twice as fast. the only problem is, the end of the second clothes line would be moving as well, which means you'd need a track to keep it extended while it moves closer.
I think you have the wrong idea of how a garage door opener works? Mine at least works almost like a chain saw. There is no winding up of a cable, it's a bike chain that is wrapped around a pole (imagine the chain on a chain-saw, it's wrapped around the 'blade' or 'arm') the door is attached to some linkage, which is connected to the chain. when the door is opened it simply rotates on the chain, and when it is closed it rotates the other way.
Place a pulley halfway between door and motor. Attach the motor chain to the pulley axle. Attach the door chain around the pulley and bolted to the ceiling directly above the halfway point (at relaxed position, should be directly above pulley). Engine would need to pull twice torque, but door will open twice as fast.
I Appreciate you're video, however have many Q:'s First. By "Accelerated Motion" You're referring to the speed of which the door opens, according to the GDO (Garage Door Opener)'s Specifications. A Standard GDO Runs @ 7In. Per Sec. The standard hight is 7ft, Thus 84 inches or = to 12 Seconds for Full Open approximately. Is you're goal to make it 8 Seconds?
Your question answers itself. If I had said my goal was to make it 8 seconds, then you would be telling me rather than asking me. And since the overall concept is more important than a specified duration, the actual number of seconds is irrelevant.
You realize that the first motor still bears the full load of the garage door plus the second motor? Also, the first motor now has to lift the garage door with the extra stress of being pulled away? In other words - doing this with gear ratios is cheaper, more efficient and has less chance of breaking down. Basically, get a faster motor. Please put more videos up so I can tell you why your ideas fail. Thanks!
Just increase the size of the sprocket to make the door open faster.

Part 2
The Exelerators have had problems with buckling doors because of the speed.
Also, over time, that cord will probably snap.

Have you heard of Dean Kamen? He actually invented a garage door opener that moves faster than people said it would be able to.
