The purpose of this report is to outline a new design for a sink garbage disposal system. The goal of this design is to develop a garbage disposal that could be made for less money, which would turn into a cost savings for the consumer and would lead to an increase in the amount of garbage disposal systems being used throughout the world. This allows the garbage disposal system to be marketed to different parts of the world that currently can’t afford the systems available on the market.

The increased use of garbage disposals, help reduce the amount of organic material in landfills. This will reduce the amount of greenhouse gases emitted into the atmosphere, which would just be another step in the direction of helping preserve the planet.

This design utilizes a stack up of seven blades that spin on a shaft ran by a small, but high powered motor. The motor is attached on the side of the food chamber, to help protect it from the water and food that passes through the system. All of the parts would be injection molded if the design is taken to production, with the exception of the motor, seals, and fasteners. This design attaches to sinks different than the current models on the market. Rather than having the garbage disposal installed directly to the sink, it installs directly into the drainage pipes. This allows installation to be easier than the current market garbage disposals.

Overall, this report outlines a design for a garbage disposal system to be installed into the drain pipes, specifically under a sink. The design is compact and light, but still powerful. This allows the design to be a cost reduction for the manufacturing process, which will allow it to be marketed to consumers for less money.
