As for whether it will constitute infringement, first of all, it depends on whether the other party has a patent right (although it generally does). Secondly, whether your invention is completely consistent with the content of the original author's paper, that is to say, whether it contains all the technical features reflected in the content of the paper (if all of them are included, there is a risk of infringement). Furthermore, does the improvement you made lead to a substantial change in the use of the product, that is, it is often used in different technical fields (if its use is changed, it does not constitute infringement).
Only a few points have been mentioned above. The actual infringement judgment needs to be compared with the original patent claim according to what you have done.
