Project Summary
Simply Paws Design, LLC, needs a new cat litter box solution compatible with their patented birch wood pellet litter. The box should retain litter while allowing liquid waste to pass through a grate, mitigating ammonia odor from cat urine. A removable tray system to dispose of waste, a ramp to help elderly and disabled cats into the box, as well to help reduce litter tracking out of the box, and an efficient grate hole pattern are key design components that must be included in the final design.
Design Goal
Simply Paws Design, LLC, has a patented model of their litter box that is designed to be injection molded and would be very expensive to have one litter box made for demonstration purposes. The main goal was to take this design and modify it so that it can be 3-D printed so that they have a model to bring to investors and trade shows for demonstrations to show off their design, their innovative litter, and to gain investments for the manufacturing to make this a commercial product.
Design Constraints
- Patented Designs – It is essential to adhere to the existing design specifications, as any alterations may infringe upon existing patents.
- 3-D Printing – To facilitate the assembly of the individual components of the litter box, minor adjustments to the design are required to uphold its structural integrity.
- Sizing – The model’s size surpasses the Rapid Proto lab’s printing capabilities, so it needs to be divided into several parts that will be assembled later.
