There is an automated shirt ironing machine I believe it's targeted to dry cleaners though. Even if someone creates one for home use it will take a considerable amount of space. Ideally we need something that can identify the type of garment (maybe even material) and then apply a particular ironing strategy. The only way a generic ironing appliance can be made is if it replicates a human ironing in a press. At the end of the day though wearing ironed clothes is a matter of fashion and materials. Might be easier to switch to materials that require minimal effort to be straightened or just people stop being concerned if their clothes are wrinkled.
