A noun version of "need" I'm trying to write a sentence with the phrase "eliminates the need to do sth..." and have gotten as far as “消除作sth..的————”, any suggestions? I don't think 需要or必须are very good choices because they are usually placed near the beginning of the sentence...
(1) A排除对B的需求 - A eliminates the need for B

(2) A消除对B的需要 - ditto



Don't forget to use 对 as 'preposition'.
