Many years ago, a medical equipment was upgraded to two products made for 3A medical treatment. Some functional hardware and screen holders of the products were shared by the existing ones. Although it is a relatively large equipment, it has also been tossed by the boss of Party A. It is often because the appearance size of 1-2cm is readjusted. At that time, it was not understood and is now appreciated. From him, I saw an attitude of product makers!
