push the envelope

Exceed accepted limits

To push the envelope is to test limits or go beyond established boundaries, especially in pursuit of innovation or achievement.

The phrase comes from aviation, where the "envelope" describes the set of performance limits within which an aircraft can safely operate.

Test pilots push the envelope to discover what new aircraft can do.

Now used broadly for anyone challenging conventional constraints: The designer pushes the envelope with unconventional materials.
