How should the elevator door edges be treated to enhance safety?

Treating elevator door edges with rounded contours significantly enhances safety by reducing the risk of injury to passengers. Sharp edges pose a greater threat during accidental contact, potentially leading to cuts or serious injuries. In contrast, rounded edges create a smoother transition when individuals come into contact with the door, making them less likely to sustain harm.

Additionally, when elevator doors are designed with rounded edges, they align with established safety standards and engineering practices aimed at prioritizing user safety. This design consideration reflects a commitment to creating a safe environment for passengers, especially in high-traffic areas where doors frequently open and close.

While options like sharp edges, flat edges, or rubber padding might seem advantageous for other reasons, they do not provide the same level of safety. Sharp edges can increase the risk of injury, flat edges might affect the door's functionality or activeness in some scenarios, and although rubber padding can contribute to cushioning, it may not always be practical for the design norms of elevator doors. Thus, rounded edges are recognized as the most effective approach to enhance safety in elevator door design.
