Nope!
That's actually, believe it or not, part of the goal of the patent system. It's a big part of it, in fact.
From the United States Constitution, with emphasis mine:
To promote the Progress of Science and useful Arts, by securing for limited Times to Authors and Inventors the exclusive Right to their respective Writings and Discoveries;
The purpose of the patent system, built right into the constitution, lies in sharing information and inventions with others.
In other words, the patent system is built as a trade. You get protection for a number of years, in return for sharing your invention with the world. That's part of why improvements are patentable, under certain circumstances.
I am personally pro-patent, but in the interest of displaying other sides, many will point out that the internet and modern culture reduce the dependency on the patent system to share in that way. But it's definitely true that having a patent on something will inject it into a pretty cool library of innovation.
Speaking to your plans, some people also get patents with the express purpose of allowing their invention to be shared. In other words, if I invent something that I want everyone to have, I can stop anyone else from patenting it by getting the protection myself.
