There are lots of different problems that have been solved related to food that the design process has been used to solve, I will be showing examples using this Diamond 9.

 
In 1930 Colone l Sanders invented KFC, the problem this could have solved is the mans calary not being enough, so to earn more money he invented KFC.

 
Wayyyyyyy back in 1660 Charles l invented the wonderful ice-cream. This solved the problem of people not having cold food on hot days.

 
In 1945 Percy Spencer invented a microwave. That solved the problem of cold and sloppy food.

 
In 1847 Hanson Gregory invented the delicious donuts. This solved the problem of all different flavours (chocolate,etc.) not having a good pastry to be eaten with.

 
In 1880 Fletcher Davis invented hamburgers. That solved the problem of all people's favourite foods being put together and not staying in place.

 
In 1940 Jordan Mott solved the problem of uncooked food by inventing an oven. Some might say that you can use the fire, but that could actually be quite dangerous.

 
In 1940, Dick Macdonald obviously invented...Maccas! This solved the problem of the money the Mac donald family wasn't earning, I think now the family is rich enough.

 
Above is the evidence of food
