● HEXAMI SHADES

A research based approach to window coverings 


Window coverings mediate our connection to the ever-changing elements of the outside world. This research project identified that outdoor sound is an often-overlooked but highly affective property of windows. Purely through research, Hexami proposes a science-based geometric solution to the problem of sound insulation.








































● RESEARCH PROCESS


To understand the products and processes in the window covering market, I conducted a series of interviews. The research still revealed a variety of gaps in existing products. 

I wrote a full research report that can be accessed here. In short, I gleaned that many people desire sound insulation but lack the products to achieve it. 






























● DESIGN PROCESS


My research on sound absorption led me to this study that discussed the absorbing properties of hexgonal cells. This guided my design process towards a flexible hexagonal cell kirigami pattern, as seen on the far right. 

























After some paper prototyping, I began 3D modeling the kirigami pattern. On the right is the SVG file I used with Amanda Ghassaiei’s code to create surface models demonstrating the folding pattern.  






The final result creates a variety of folded states ranging from flat and opaque to a hexagonal cell structure. For maximum sound insulation, this would be backed by a traditional roller shade to complete the cell structure. It can be rigged to a traditional threaded cord and pulley system. 













































For material, I proposed felted wool, which is insulating both heat and sound. Its rigid structure can be scored, folded, and cut — as seen in Gaëlle Burklé’s work on the left. The moisture-wicking and antimicrobial properties of wool are also convenient for application near a window. However, any material that is rigid and flexible enough to hold origami could utilize this system.




























● TO CONCLUDE


This project was an exercise in design research, seeing how far a concept could progress before prototyping begins. The result is a socially, functionally, and scientifically backed window covering concept. It fills a gap in the market with a novel and beautiful solution.

This project is only the beginning of a full design process. Hexami’s next stages would involve material experiments, sound absorption testing, and further design development.
