The design concept comprises of a closed loop feedback control system where light dependent resistors will be utilized as sensory components sending a microcontroller feedback signals containing information regarding the sun's light incident intensity. If the sun's light intensity decreases from a pre-specified intensity value, the microcontroller will send a signal to the relevant motor, adjusting the position of the sunshade. Two separate poles will control the movement of the sunshade. The lower pole is fixed and inserted inside a plate, rotating around its own axis dictated by a stepper motor, hence allowing rotation that follows the sun's natural azimuth angle. The upper pole is connected to the lower pole through a pin joint and will follow the sun's natural elevation angle dictated by a second stepper motor. Aluminium Alloy 6061 was chosen as our pole material due to its relatively high strength to weight ratio in addition to its durability, consequently achieving the desired portability and long lifespan of the product. Assessments conducted throughout this project proved the material's ability to support the design structure and external loads subject to it. The structure will be foldable and be conveniently carried with a multifunction bag with simple installation steps to make the product user friendly. Initially the product will be tested in Germany and if met with success, will further expand to global markets located in coastal regions. The estimated total price for one unit is 914.99 euros. Our product pitch, design concept, and features are presented in an audio-visual format and is awarded the Science Communication 'Gold Leaf Prize' for an outstanding online video presentation on July 6th, 2021 in the category of 'Audience Choice'.}, language = {en} }
