Broadening of claims 

A statement regarding use or intended purpose in an independent product claim may be deleted only if the application as filed offers a basis for the assumption that the product can also be used in some other way (and if the statement of purpose does not amount to a functional limitation).

The broadening of a claim by exchanging a particular feature for a more general feature cannot be based on an indication that it would be obvious for a skilled person (see also H‑V, 3.2.1).
