widen temporarily a part of widen temporarily a p art of the score?

[Mehmet Okonsar]

    what command can be most simply used to widen temporarily a part of
    the score?
    More precisely:
    I just want to widen the spacing for a part of the score to avoid
    collisions between clef changes, accidentals etc. all at once with
    hopefully a simple command.
    #'force-hshift?
    #'extra-offset?
    ...
    what to use and how?
    Spacing-Engraver and spacing spanner entries was of no help to me..
    thanks
