GapGuard utilizes a known retractable mechanism housed in a sleek 3D-printed case to completely eliminate bathroom stall sightlines.
Standard US restroom partitions leave a 0.5 to 1-inch gap between the door and pilaster. This flaw creates uncomfortable visibility, compromising user privacy and dignity.
Unintended eye contact from passersby is a primary source of restroom anxiety.
Affects over 80% of public facilities, from universities to airports.
"It's just an uncomfortable design flaw we've accepted for too long."
A compact, triangular housing unit that mounts to the door frame. The privacy film rolls out seamlessly to bridge the gap.
GapGuard replaces expensive door renovations with a simple add-on. The triangular profile is designed to be unobtrusive while housing the retractable mechanism.
The 60° angled case fits perfectly against the door frame, deflecting impact and blending into the architecture.
Like a measuring tape or window shade, the film extends to cover the gap and retracts when not in use (optional spring-loading).
Engineering decisions driven by sustainability and functionality.
The housing is 3D printed using Polylactic Acid (PLA), a biodegradable thermoplastic derived from renewable resources like corn starch. Lightweight yet durable.
We are currently researching the optimal "tape" material. Candidates include vinyl composites and opaque PETG to ensure flexibility, opacity, and tear resistance.
Unlike rigid filler strips, our retractable film adapts to door movement. It rolls out seamlessly from the case, preventing jamming or damage to the door hinges.
