You sound like someone in need of a development grant. I'm not sure about the market in Slovakia. But in the US there are oopportunities to do this through finding an interested party either in government or academia.
Ehm, market in Slovakia for something like this is pretty much nonexistent - tiny, 5 million people country with very little advanced R&D industry. In fact, most of our industry is around assembling cars for others thanks to low wages and cheap workforce. Slovakia is the largest car manufacturer in Europe, I believe. VW, Peugeot/Citroen, Kia - all have big assembly plants there.
And getting a grant - that's pretty much a hopeless adventure because of the corrupt, impenetrable and incompetent state bureacracy. Heck, even the universities and Slovak Academy of Sciences are unable to get grants through the government or only with insane difficulties. Private R&D grants are practically unheard of - companies will rather sponsor sports teams and political parties where they could get kickbacks and business from the state than science ...
And to Daqq - your have pretty much two options:
1) If you don't want to monetize your invention outright, but don't want someone else to profit from it without you seeing a dime, then do publish it, ideally in a large journal or conference catering to the field. That establishes prior art and nobody could patent it anymore, potentially preventing you from commercializing your own idea later. If it is something that is actually missing in the market, then it is likely that someone else is working on it too and it is possible they will try to patent it, not being aware of your work. You could end up locked out of your own idea.
E.g. I have a published paper from 1998 or so on multi-touch interaction, years ahead of the work of Johny Lee, Microsoft, Apple and their patents. I published it only in a small local conference back in the day, so if I wanted to actually get over their patents, it would cost me a ton of time and money now ...
Publishing is a much cheaper and easier option if you want to defend against patents than trying to get a patent in every country in the world - that costs a lot of money for both getting the patents and the fees to maintain them. Moreover, the only thing it grants you is a paper that says you can sue the culprit. Good luck trying that against some Chinese or Korean cloner or a big megacorp with deep pockets ...
2) If you want to commercialize it, then do as the others said - keep it secret and build a solid implementation. Then you could look for investors or a company to sell the license to. Or you start a company manufacturing your gizmo yourself. Having only an idea is useless - investors have "pie in the sky" ideas a dime a dozen, that won't convince anyone to put money on the table today. Well, there are exceptions, but you probably don't want to go there if you have a genuinely useful and working gadget ...
