The Spark of Genius that Led to LightSpray Technology
The Cloudboom Strike LS story began with a serendipitous moment and a burst of creativity. Yohannes, a key player in this tale, had the innovative idea of using a hot glue gun to create intricate, spider web-like structures. This simple yet brilliant concept evolved into employing a robotic arm to spray a thermoplastic material called LightSpray onto a shoe form, crafting a seamless, sock-like upper. The inspiration for this technology struck during a Halloween event, where a video showcased using a hot glue gun to create detailed spider web designs. This sparked the idea of rapidly creating textiles on complex shapes, with a shoe being the perfect candidate to test this novel method.
The development of the Cloudboom Strike LS was a journey filled with trial and error. What began as a simple idea evolved into a complex project requiring the collaborative efforts of designers, engineers, and various other experts. The team had to automate the process to turn this concept into reality. They programmed a robot to move the nozzle and spray the material, requiring meticulous calibration to ensure precise application. After a year of dedication and refinement, the project gained more resources and became a priority within On’s innovation department.
