| Abstract: |
Conventional staircases in residential and public buildings often lack integrated accessibility solutions for physically challenged individuals. To address this limitation, a mechanically actuated staircase system is proposed, capable of transforming between a stepped configuration and a ramp/platform configuration.The system incorporates mechanical linkages and actuation mechanisms to enable controlled reconfiguration of the stair geometry. Through synchronized motion of structural members, the staircase can alternately function as a conventional stair assembly or as an inclined ramp, depending on operational requirements. This dual-mode functionality enhances adaptability without requiring permanent structural modifications.The primary objective of the system is to reduce physical effort and improve accessibility in built environments. The design methodology emphasizes mechanical reliability, structural stability, and ease of operation. The prototype development was carried out by considering economic feasibility, manufacturability, and social acceptance. The implemented mechanism demonstrates a practical and cost-effective solution for improving mobility assistance in day-to-day applications. |
