Kevin E. Flynn · Answer

Many inventors invent items that are used in connection with earlier inventions.  Surprisingly, the inventor of the modern can opener came much after the invention of putting food into a can to store it. 
 
As with any invention, you don't get a prize for making an invention.  You make money by selling a good or service that people want at a profit.  The patent keeps others from selling the same solution and thus cutting into your market share or profit margin (by forcing you to sell at a lower price as you have competitors selling your solution).  
 
Sometimes, you can sell a patented idea or a patent pending idea to the people that own the original patent.  They are likely to find your idea compliments there product.  Sometimes, people are stubborn and won't pay for an idea that they did not invent.  Sometimes they will try to design around your solution to provide a competing solution 
 
It sounds like it may be time for you to work closely with a patent attorney to sort out if this project is worth your time and money.  You may have something. 
 
I hope this helps.
