11.5.3 Combination

Combination is where two or more existing devices are combined to produce something new. For example the Toggle (Figure 45) combines a screwdriver and wire stripper for the outer and inner cores of an electric cable. It was designed by an OU student of an earlier version of the course T307: Innovation: designing for a sustainable future to combine into one the tools needed to wire an electric plug.
