Smart Doorknob Cleanser

During the sensitive times of a global pandemic, we have learned over time that diseases such as Covid-19 can live on surfaces for days. The senior project idea is to design, construct, and implement a prototype able to disinfect doorknobs after the surface has been encountered or used. To fight against harmful bacteria's, there is a need to attack one of the main sources where bacteria is being transmitted the most. In fact, scientists have determined that on average a minimum of at least five different colonies of bacteria are on a single doorknob at any given time. The purpose of the device is to spray a mist of alcoholic solution onto the doorknob surface allowing the solution to disinfect the main surface area. The main objective of this project is to keep the environment clean and reduce the spread of viruses and germs. In addition, the device is set to follow constraints that provide the opportunity for the device to be cost effective, efficient, and adjustable. As a result, these constraints will improve productivity, safety, and be more user friendly to consumers. By applying previous engineering coursework, the plan is to incorporate notes from classes such as fluid mechanics, machine design, network analysis, and computer aided design to fulfill the needs of the project. The device is planned to include a fluid mechanism that will be used to spray the alcoholic solution after the doorknob has sensed motion within a specific time interval. Also, referring to the constraints of the project implementing a refillable cartridge with automated fill level notification would be ideal in making sure the alcohol solution can be easily replaced when the cartridge has reached a level of emptiness. These fill levels will be indicated in a form of a display screen communicating to the consumer that the cartridge is empty, half empty, or full and ready for use. This ensures the device is indeed performing and communicating whether the solution needs to be refilled. Overall, the goal is to create a sanitized and trusted environment for consumers when utilizing the smart doorknob sensor. This device would be used as a combat against diseases being transmitted in public areas such as office buildings, schools, and public bathrooms

Portable Car-Washing System

The Portable Car-Washing system was developed for the benefits of improving consumer focus. The system was designed to provide comfort, convenience, improve health, and durability to consumer vehicles. Many consumers face scenarios where their vehicles are being damaged by car washing companies. In fact, car wash companies are known to tear off antennas, side view mirrors, and front/ rear bumpers. Also, harsh chemicals and low-quality car shampoo are being used at these establishments which eventually cause rust. These harsh chemicals can vary from all brands of industrial strength alkaline enhanced degreasing shampoo which leads to oxidation of the paint and corrosion. On the other hand, devices such as the Portable Car- Washing system are innovating a touchless car wash facility introducing a safer washing system
