This is a mind map of the 3 essential questions. (below)
I have expanded on them and chose a problem, which was cooking. Cooking might be a problem as they have to stand to cook and it might be tiring. It will be difficult as they might not know how long it will take to cook some food. This is why I selected thin challenge. I am supposed to come up with a product to help them.
I am currently thinking of a product, that is a stove with a timer, and has adjustable height. It is also able to time you for some simple things like frying eggs, and other things like steaming things and others.
I hope you like my idea.
