DI: What is the main principle, idea and inspiration behind your design?
TS : "I come from an architectural engineering background and have always been drawn to the concept of modularity and flexible structure. As a specialist in building construction, I've come to recognize the crucial role of connectors in creating sturdy structures. Whether it's wooden lumbers connected by nails, glue, or bolts, or metal components connected by bolts or welding, these connections significantly contribute to a building's strength.
I realized that aluminum extrusions have numerous advantages over traditional wood or metal elements in the realm of human shelter. However, for over a century, effectively connecting two hollow extrusions has posed a problem. Aluminum welding is excessively expensive, and bolting two extrusion elements together doesn't adequately withstand lateral loads.
The practice of using aluminum extrusions for building framing has been around since 1904, but it didn't gain popularity in the building industry, primarily due to connection issues of hollow aluminum elements. Companies such as Switzerland's Syma-Systems have attempted to find locking solutions, but their approaches were only suitable for interior framing. Architect Buckminster Fuller's interlocking joint invention for aluminum extrusions, used in geodesic dome structures, marked a significant advancement.
After years of research and study, I have developed an improved interlocking clamping system for modular aluminum geometric profiles. This breakthrough allows us to reimagine traditional connector techniques, making building structures more durable, comfortable, efficient, cost-effective, and sustainable. My design lends itself to the creation of recyclable, relocatable, and renewable building structures, significantly contributing to a sustainable future.
As an architectural engineer, I take great pride in making a tangible contribution to the evolution of building construction and positively impacting the world around us."
