Patented invention needs a brilliant engineer!Blind

who is the winner ?

Hi David..I can see,you have that mechanism in 3D.. can you share that with us ?

Why should a person participate when there is only one prize? The likelihood that at least some part of a participant&;s working time will be paid is minimized. It is always better for all prizes to be AT LEAST three. I personally do not participate in a competition with one prize. Firstly, it is unreasonable and secondly, such an attitude towards potential participants is insulting. "Come, as many people as you can, work on my problem, and I will pay only one." No thanks.

It&;s a 2.5 inch pin that will be actuated thousands of times and be easy to replace the actuator when it wears out.

You have been online 2 hours ago and you haven&;t answered my question, honestly I am not wasting my time here any more. Go and have fun with these desperate idiots.

Please reply, if you intend to make your contest worth while.

By the term "deadlock" does it means that it is a one time emergency lock that needs to be manually unlocked?

Would you please clarify if the volume 4*4*6 inches is the allowable space after the linear actuator extends or before? Thanks.

The two pics you shared recently are un available

Just answer this question:
By the term "deadlock" does it means that it is a one time emergency lock that needs to be manually unlocked?

This a dead bolt lock. It must cross the first threshold and then cross the second threshold 2" further along the pin throw. A design that is higher (longer) than 6" will not work in this application. Super compact, super simple, easy to swap out motor, ...seen some killer stuff from y&;all.

I cannot edit the original contest with better details sorry,

I need the lock and mechanism to be as small and compact as possible. The lock mechanism as well as the actuator have to fit in the volume. so something 4x4x6 inches would be good, 3x3x6 would be better, and 2x2.5x6 would be best!

The actuator ...like these ones, below, super dependable and cheap! Easy to swap out and replace, multiple actuators will be working in tandem, And that is why I am needing the simplest mechanical system an engineer can come up with.

Your well designed bracket or housing would encapsulate hopefully the smallest size possible (2x2.5x6) ....be easy to remove to swap out the actuator, or better just have a way of replacing the actuator itself without removing the housing. Access would be from the back or side of the mechanism, The actuators I am super trying to use are 1" x 2.5" wide, and 5.5" long when open. 5" when closed . The actuator can be used sideways also (2.5") ...up to you,


Here are a bunch from aliexpress

I also have the same question as @richards. Would you mind dimensioning the enclosure so we have a clear understanding of the space corresponding to the orientation. Thanks.

OK, long story short: Workspace: 4x4x6 inch; Input: 0.5 inch vertical and output "Drum Roll": 2.5 inch horizontal
The 2 questions I have is:
1- By the term "deadlock" does it means that it is a one time emergency lock that needs to be manually unlocked?
2- If you have that linear actuator on Amazon, why do you want to recreate the wheel? DOes it doesn&;t fir in the 4x4x6 size?

Please could you clarify the orientation of the 4" x 4" x 6" maximum enclosure volume. Which is the 6" &;height&; dimension: is it parallel to the actuator throw axis or orthogonal to both the actuator and locking pin axes?
Does the actuator have to fit inside this volume as well as the mechanism? If so, can you give some basic overall dimensions of the actuator.
Thanks

This an example of the actuator we want to use. An off the shelf very cheap and reliable generic motor with a .5 inch throw. 12V. To be mounted perpendicular to the 2.5 to 3 inch lock pin. So the pin would be extended at least 2.5 inches out of the enclosure in the lock position. And retreat 2.5 inches into the 4x4x6 enclosure when unlocked.
This is not for a working prototype so the power of the motor doesn&;t matter. It is just to create the simplest 3d model that can be shown to work in 3D. A mounting bracket for the system would also be necessary. Maybe a rack and pinion system? Or levers? Both? Just as simple as conceivably possible, and it only has to be shown to work in the 3d model.

Are you asking to design a mechanism for displacing 2.5 in a lock pin using a linear actuator with .5 inch stroke and 10 lbs force? Additionally: the linear actuator is to be installed in a 4 x 4 x 6 inch space.
My first question is: Why using a linear actuator for driving the pin? Is it ok if we use a rotary actuator?
Another question: Is 2 lbs (10 x.5 /2.5) the required force? For a locking mechanism, seems a lot

All I have are those 3d screenshots. neither of those designs will work but do give a picture of the actuator with the .5 inch pin throw and in general how it should work.
