Taking your example a paper clip and a binder clip both have the same fundamental form you have to separate two parts of the thing that then squeeze the paper together. A stapler is a leap step in binding things, where an interely different fundamental form is used to permanently bind things. An air stapler has a different operating principle (I don't push a staple a pneumatic driver does it for me) but it is not fundamentally different from a regular stapler in how it binds things. Storing this comment on a server is several leap steps forward from archiving a printed document and binding it to other comments in this thread. :)
