DZ1 is a pair of door handles designed for large, heavy doors in public buildings. The system allows doors to be operated either by arm or hand, reducing physical effort and minimizing direct hand contact in high-traffic environments.
The project focuses on intuitive interaction, universal accessibility, and hygiene-aware use. By shifting force application from the hand to the arm when needed, DZ1 improves usability for diverse users while responding to public-space health concerns.
The handle features a simple, streamlined geometry with two clearly differentiated functional zones:
_ an upper section optimized for arm operation
_ a lower section shaped for conventional hand use
Subtle inclination and controlled radii guide the user’s movement and visually communicate how the handle should be used—without text or signage.
DZ1 is conceived as a monolithic metal component, suitable for materials such as stainless steel or aluminum. A satin or brushed finish emphasizes durability, cleanliness, and compatibility with public architectural contexts, while supporting industrial manufacturability.
Developed within an academic project in collaboration with FSB, DZ1 addresses real conditions found in public buildings such as shopping centers, banks, and institutions. The design responds to heavy door weight, high usage frequency, and evolving expectations around accessibility and hygiene in shared spaces.
