Thank you for the answer. It’s very detailed, structured, and easy to follow. The only feedback I would have is to say I would first ask what the goal of the design of the washer / dryer is. Do they have a particular objective in mind? (e.g. do they want to enable faster wash, increase lifetime of clothes, or something else) If they don’t have an objective in mind, I would select one particular objective and focus on features that help achieve that particular goal.
