碩士 === 國立臺北科技大學 === 機械工程系機電整合碩士班 === 107 === This thesis presents a conceptual mechanism design for conversion between round table and square table. Convenient and simple to operate is the main principle of the design. This design applies four sets of crank-slider in which the slider is the input link that the extendable table board rigidly attached, and the output link of each set is connected together. A user, therefore, can move any piece of the four extendable boards stored under the round table board to drive the other three boards to lift outward simultaneously and become the square table. This design also includes a mechanism to reduce the gap between the round table board and the extendable table boards by forcing the extendable boards to move toward the round table board. Similarly, by pushing any single extendable board inward after a short pull outward, can simultaneously drive the other extendable boards to go down under the round table, and therefore return to round table. The dimensional synthesis of the required slider-crank is obtained by analytical approach, and then constructs the corresponding 3D model via SolidWorks software. The kinematic simulation and interference check are also performed via the functions of SolidWorks to check its correctness of this novel mechanism design. A prototype of the mechanism is made and tested for operation. The preliminary result has confirmed its feasibility.
