: Dear Class: : In addition to the requirements listed below there are a couple other things that you should consider as you go through your ideation process. One of the major obstacles to overcome is the heating of the 1 liter of water. This is a major task – you probably don’t want to take it to the boiling point if you can avoid it (for all sorts of reasons that you will want to argue convincingly). Some techniques that you should look into are thermoblock heaters, immersion heaters, tube heaters, and boilers. It is acceptable here for the water to contact something other than the glass/ceramic/stainless-steel. Once you begin the brewing process the water and grounds should be in an appropriate container. : The mechanical “pressing” of the coffee grinds and water does not need to be a true press. You do need to separate the grounds from the liquid without using a gravity feed filtering process (i.e. the drip coffee maker) or a “vacuum” filtering process (such as the Bodum vacuum coffee maker). The filtering process must involve mechanical work. : As previously discussed, you need to provide detailed drawings of the parts that you’re manufacturing. You also need to address safety and recycling (we’ll talk about this more later). Closure equations should be used on features that require tight tolerances. Any standard parts need not be detailed, but you should rough them out for the assembly process and the assembly drawings. : All the Best, : Greg : P.S. Please continue to questions and we’ll continue to provide clarification as much as we can. : Requirements: : -be made in the USA : -sell on the retail market for $100 : -use electrical power and consume a maximum of 10 Amps (120 V) : -make 1 liter of coffee : -the coffee and grounds must sit together : -heat the water : -be easy to clean up : -use stainless, glass or porcelain where the materials come in contact with the water and coffee : -grounds must be mechanically removed manually : -gages or some sort of feedback
