ideas for inventions

TGO

I've had a number of ideas for inventions lately. I lack a strong background in physics and chemistry to an advanced level so please try and forgive me for my ignorance as I would like to learn what I can at an appropriate pace and enjoyable manner. Sorry if to some of you more familiar with the advanced fields these devices involve have to go through the miserable agony of reading these stupid ideas if they are indeed stupid like they probably are. However, one of the most enjoyable ways to learn is throwing the hypotheticals and the wild ideas out in the open so here goes...



Idea 1:

Impact-reactive Stun and Smoke Concussive Explosive (ISSCE)

The basic idea is an explosive device, spherical in shape. It has 2 chambers. The first chamber is the detonation device for the concussive stun mechanism (similar in functionality to the M84 stun grenade). The second chamber would house the detonation device for the smokescreen releasant mechanism (similar in functionality to the L83A1 smoke grenade). However this device would not just be a simple combination of two ingenius inventions. It is a step up as this device would require no timely means of detonation. No pin, no fuse. Both chambers would detonate simultaneously. All it requires is the force of hitting a surface, such as the ground to detonate. Making it perfect for a number of uses (escapes, entries, etc.).



Idea 2:

Artillery Negation and Deflection (AND)

This suit would essentially be made up of several layers. The outter layer would emit a powerful electromagnetic fieled. Artillery fire from regular firearms would bounce completely off or skew off course from the wearer of the suit due to the electromagnetic force surrounding the suits outter layer. The suit would also have 2 detachable barrels that contain a chamber loaded with projectile EMP devices that could be fired from either of these barrels located on each wrist area part of the suit, and cling to any metalic based target and then procede to detonate as soon as attached shortcircuiting targets from miles away from safety to avoid confrontation with heavier artillery such as tanks and missles. One curious thought I had, is if the electromagnetic force generated from the outter layer of the suit was strong enough, would it be capable of literally moving landmines as you walk closer to them? In any case. If heavier artillery could be handled from a distance safely, and light artiliery from regular firearms couldn't touch you, I'm having a hard time imagine just what an army could do to react to such a device. I was even hopeing it would be possible to add in a few internals layers that would attract and trap oxygen into the suit, and used the converted energy obtained to focus it to joint muscle parts of the suit, such as the knees, elbows, hands and feet so essentially you would have more force behind your movements and actions. You'd be more agile, stronger, and the weight of what I could only imagine would be a heavy suit would be easy lifting for you with all the extra force helping you support the weight. The question is how much energy could be trapped and how much of a difference could it make? Would you feels 2 times stronger? 10? Or barely any stronger at all with that extra energy being put into force and used at your whim? Heck, assuming I scrapped the idea of the electromagnetic deflection and EMP projectile barrels and commited the entire structuring of the suit to the act of trapping oxygen or some kind of external fuel that is all around us (perhaps sunlight if not oxygen), and used it to fuel force into an action such as jumping, would it be a noticable difference if charged long enough in the sun or left outside (since I know the absorbtion process would probably take some time). Would you be able to jump twice as high, move twice as fast, lift twice as much, or would it be a miniscule difference?

The feasibility of any of the above and many some ideas on just how they could become feasible (if at all possible) would be appreciated. It's always fun for me to throw around some insane hypotheticals. Again, sorry to the veterans out there for seeming moronic haha. I'm just really curious if any of these inventions are possibilities. And not thatits nearly as interesting or probably useful, but I also thought of a final small minuature invention...



Idea 3 (well a mini-idea at least):

Basically a small beacon like device with a propeller that could be wound up. When wound up it would have a dial to change what elevations it would be preprogrammed to fly to and it would fly and substain its elevation. Once there it would flash a red and blue distress light, emit a loud noise, and possibily emit a radio transmission of some kind that could show up on radar. Just enough to get the attention of any go'er byes or rescue aircraft or boats that may be nearby if you are stranded on an island for example. Perhaps it could even release a luminous smoke signal (phospherus based) at night? Havn't come up with a name for this idea yet. Mainly because it is probably the worst of the 3 haha.



Okay now thats it, thanks guys for any and all responses and help!

Hate to rain on your ideas, but I see a few problems.
How do you prevent accidental firing? (E.g., User carrying the device trips and falls.)

Take a look at the Mythbusters "curving a bullet" episode. They tried altering a bullet's trajectory with some pretty serious magnets and measured virtually zero effects.

Good point. Although I guess at that point it would come to just being extremely careful when in the possession of such a device. Maybe perhaps it is only able to be detonated when held with enough pressure on small pressable groove or button. Then once the button has received enough pressure and been held for long enough, say a 10th of a second or some fraction of that the next sudden surge of pressure or shock will send it into detonation, but only after the grove or button has been released (so it would have a way of knowing you didn't just fall on the button, you pressed it knowingly and then threw it hard enough to detonate it).

Yeah out of all the ideas a suit that could deflect artillery was definitely getting doubts in my mind. What about an altered version of the suit that attempts to amplify the strength and speed of the person (I explained my idea of it near the end of my last post) minus the electromagnetism idea. Would that version of the suit be more feasible?

Heh, not surprised. But glad to see we have plenty of survival technology already. Anywho thanks for the debunking, criticisms, and suggestions guys. Keep them coming, only way any real learning is ever done so its welcomed.

I was actually thinking about this too. My idea was a nano suit type thing (Crysis) that would chemically and mechanically work to make you faster, more agile, stronger etc. Unfortunately I don't have enough technical know-how to elaborate more :).

There are a few companies developing Exo-skeleton suits. I've seen the Raytheon (named XOS) suit in a few videos.

WhoWee

The Raytheon suit looks hard to use - a little bulky.

The Lockheed version seems a little more practical.

On a personal note - I want one of these - wearable motorcycles.

On a personal note - I want these (without needing to be an amputee) - carbon fiber exo legs to let me run 25 MPH

That seems more feasible than an entire exoskeleton. Even a running robot with these would be fun to try.

How about wireless Cat-5.

...

Two RJ-45 connectors that communicate wireless. Eliminates the need for a wireless card. I remove my pending patent so you guys can invent it. It doesn't (and shouldn't) follow 802.11 standards.

In a practical sense, an exoskeleton connecting "feet" to a spine (that a soldier could strap on like skis only above the device with about 2 -3 inches of ground clearance) and for the arms a type of sleeve with the device attached (extending past the hands) and connected to the spine makes a lot of sense. The soldier could carry more supplies as the weight would be transferred through the spine to the ground. Also, this type of exoskeleton would not require supplemental power - the spring action would assist movement.

Bill Simpson

The biggest issue I see is "how do we get the needed knee action without power?"

There are videos out there that show runners with two peg legs. That is hopeless.

Like kids "pumping" a swing, we can put energy into the spring by driving down as we plant each foot and we get that back as it drives us forward.

But then it seems that the critical mechanical issue is how to get that spring leg to maybe rebound somehow so that it flexes the knee enough to allow us to swing the leg forward and be ready to plant that foot for the next step. I don't think it is feasible to demand that our legs put enough energy into the spring for us to bend the knees.

If some brilliant mechanical guy can think of a way to get that knee action without needing power and controllers and motors and ... then I think this might actually be a feasible hobby level project.

WhoWee

I would think the knee could be constructed with two pieces - the lower section sliding out of the upper section to follow the contraction of the leg. Then, when the leg is straightened, the lower piece would slide back inside until it hits a "stop" - where a re-coil spring action would supplement the next motion?

Bill Simpson

You can buy exo-legs off the shelf today

http://www.google.com/search?q=running+spring+stilts

and some of those links say it is possible to run 25 MPH!
And they do this without knees.

WhoWee

Those look good for running - but not for carrying a heavier load.

I hope I didn't write anything to imply that these spring exo-legs were going to substitute for your skeleton so you could carry 400 pounds.

Worse, all these seem to be avoiding the difficult knee operation I initially said needed to be solved by attaching these at your knees and below. That makes these simpler to design and build, but will limit these to the strength of the muscles and tendons and joints of your knees, a serious weakness. My original hope was for something that might attach at the hips and all the strength of the legs would be available to pump energy into the exo-legs. Some search results even tout how much exercise these will give you, a bad sign when you are hoping for something perhaps as efficient as a decent bicycle while letting you run at 25 MPH.

But maybe someone can take this as an early demonstration of feasibility and build something better.

WhoWee

Any thoughts on my 2 piece sliding knee mechanism idea?
