SCISSOR MECHANISM

During this project, a problem situation was identified, actions were planned, research was conducted on possible solutions, a system was modeled, numerical analysis was performed, and a scissor lift table was created. Through project planning, manufacturing processes and methods were established. Using Solidworks, the model, technical drawings, and assembly simulation were created to obtain maximum stresses. By analyzing stress, reactions were determined at all angles, shear and normal stresses on plates, and buckling to numerically verify that the designed mechanism fulfills its function.

Our objective was to design a scissor lift table with the function of raising and lowering a projector using a simple mechanism. This product is intended for use by a wide variety of industries and clients, with its primary function being to protect and provide a clear view in a classroom. Anyone should be able to operate this stand, regardless of the type of mechanism or whether they are a student, teacher, or director. Therefore, the finishes of the parts should be rounded to avoid injuries, and the mechanism should not have exposed parts that could pose a health risk to users. Through lightweight and practical materials, the mechanism of this product will operate efficiently with smooth and noise-free movement. As the base is planned to be suspended from the ceiling, the required maintenance should be minimal, and it should have high structural rigidity.

Regarding design and colors, it should not be extravagant to avoid attracting attention and potentially distracting students. Optimization of materials and costs should be considered for easy manufacturing and competitiveness in the market. Finally, the following specifications should be taken into account for the product:

Maximum dimensions of the base: 11 in x 8.5 in
The final height should be at least 3.875 times the initial height of the platform.
It is planned to support a maximum weight of 70 kg.
