Re: There should

The IgNobels don't have a fixed category list, so nominate them here. In 2013 there was this prize:

SAFETY ENGINEERING PRIZE: The late Gustano Pizzo [USA], for inventing an electro-mechanical system to trap airplane hijackers — the system drops a hijacker through trap doors, seals him into a package, then drops the encapsulated hijacker through the airplane's specially-installed bomb bay doors, whence he parachutes to earth, where police, having been alerted by radio, await his arrival.

In 2010:

ENGINEERING PRIZE: Karina Acevedo-Whitehouse and Agnes Rocha-Gosselin of the Zoological Society of London, UK, and Diane Gendron of Instituto Politecnico Nacional, Baja California Sur, Mexico, for perfecting a method to collect whale snot, using a remote-control helicopter.

2004:

ENGINEERING: Donald J. Smith and his father, the late Frank J. Smith, of Orlando Florida, USA, for patenting the combover (U.S. Patent #4,022,227)
