What percentage of difference needs to take place for a design not to infringe on an existing patent? I have an invention that mirrors the claims of this one but my design might be different, I wish there were more detail in their drawing. Any help is greatly appreciated!

Welcome to Ask Patents. The style of all Stack Exchange sites is to not have "thank you"s and a signature at the end of a post. I think some people got carried away with elaborate cute ending phrase of no value at one time. –  George White Aug 20 at 18:17

There is no % difference concept in patent law. The claims state what the patent owner has as his exclusive territory - drawings are just examples of a way to carry it out but the words of the claims set the boundaries between what you can and can't do.
