Abstract

This report outlines the design, analysis, and future prospects of an innovative folding blackboard project inspired by the YOYO stroller mechanism. The project's goal is to make a writing surface that is light, easy to move, and structurally stable for classrooms with limited space. This design employs a single–degree-of-freedom (1-DOF) linkage to achieve compact folding and smooth deployment. We integrate kinematic analysis, SolidWorks simulations, and an initial prototype to connect theory with manufacturability, reporting folding ratio, stability indicators, and key trade-offs observed during iteration.

Keywords:

four-bar-linkage, a single-degree-of-freedom, fiber-reinforced plastic(FPR), mechanism
