Here's basically my idea, it's essentially a cross of a jaccard and a needle, it allows even injection of whatever liquids you want into a steak or other piece of meat, be it marinades, enzymes, brine, whatever, evenly throughout the meat.
To use it, you would push it all the way down, then slowly pull the two boards together as you draw up, which would disperse the liquid throughout the meat.
This already exists and is in widespread use across most of the industrial world. You can buy home versions on amazon.

System needs to be more modular. What happens if the steak is bigger than the area of needles? You can't just move it over and jab it again because it would interrupt the flavor cross section. I suggest making some sort of telescoping frame that allows for the adding and subtracting of needles based on meat area.
