Again, nice presentation. I think the problem statement is summed up nicely, and I think the design is well presented. I don’t immediately see how the design solves for the problem statement. How does this cutting board save space over just using a smaller cutting board?
I think the solution set for the problem could be blown out more. More efficient small range/sink/oven/fridge… for example the Fisher & Paykel drawer style dish washers are a nice solution here because they are two drawers. A one or two person household could use clean dishes out of one drawer and as the use them move them to the second drawer (I have friends who do this)… combining both storage and dishwasher spaces. I’d like to see some more clear space saving.
