Inflatable castles (closed inflatable trampolines, bouncy houses, bouncy castles, moon bounce, moonwalks, or CITs) are temporary and buildings and similar items that are rented for functions, school and church festivals and and used for recreational purposes, particularly for children. The growth in popularity of moonwalks has led to an inflatable rental industry which includes inflatable slides, obstacle courses, games, and more. Inflatables are ideal for portable amusements because they are easy to transport and store.
So, is this where engineering simulation can step in and make the trampoline safe enough for the AAP? Perhaps. First, someone needs to find the evolutionary leap that usually accompanies the redefinition of a product. Playground equipment in general took that leap by changing materials and examining child interaction with the individual pieces. Trampolines are ripe for a reinvention. Basically the same design of the transfer of potential and kinetic energy utilizing the coiled springs attached to a mat of tightly stretched fabric has been in place since the inception of the popular trampoline in the 1930s. The modern “bouncy castles” or closed inflatable trampolines have started the evolution, but they aren’t practical for the everyday consumer.
