DeRoyal’s original product demanded frequent refilling with ice, through a restrictive opening. Injured patients were expected to lift and turn the unit upside-down when emptying used water. Sustainability was also an issue, with the PU insulation originally being permanently sandwiched between two blow-moulded parts.
Considering the target audience, the final design was given a more familiar form (an American ‘cooler’ or ice box). Improvements included: the largest possible opening for refilling; a water drainage spout, and removable EPS insulation. All held together with standard fasteners.
