Product Usage
Insert 3 D cell batteries, or plug an AC adapter to power the feeder. Assemble the feeder by attaching the dish to the feeder near the opening at the bottom. The hopper that holds the food attaches to the top of the base with a simple rotation that locks it in place. The top to the hopper works in the same manner, where a small rotation of the hopper cover locks it in place.
The Hopper should be filled with pet food of the owner's choice, so long as the food is not moist or significantly large e.g. a dog treat. Turn the feeder on using the switch on the bottom.
Mechanical Function
The feeder accepts food from the hopper located above. The feeder contains four sets of fins, each connected to an axis parallel to the floor.

Design for Manufacturing and Assembly
The dog feeder is already manufactured very simply and efficiently. The part count is low and only necessary parts were manufactured. The design is very simple. Most parts are plastic and thus easily manufactured with casting or molding, which is the method chosen. The material should not be changed because plastic is the most logical choice for reasons of cost and ease of manufacturing. Any change in material would spike the price of the machine.
