Balloon Seat - Structure Borne from Strategic Inflation
When balloons are threaded through a jig and later filled with air, structural tension secures both elements together and forms an unique joinery through inflation.
Inspired by this phenomenon, experiments were conducted to explore the concept of functional expansion in materials and the balloon seat is one apparent manifestation.
By introducing localised heating on PVC pipes before inflating them from within via a collapsible silicon ball, it creates a natural, bulbous joint that is strong enough to secure a wooden seat, armrests and a backrest.
When this process is introduced at key intersections, the resulting structure is well capable of supporting a person’s weight, all without the need for screws, nuts or bolts.
