I believe that when Urahara created the Hougyoku he thought what he created affect Shinigami and Hollows to transform into each other. Though I think it needs other people desires to gain powers as it cannot do anything on it own yet as maybe it is hoping to control Aizen with enough powers like the destruction of the barrier between Shinigami and Hollows and the awaking of Orihime's and Chads powers. This are only thoughts not facts.
