Limited by the cost and other factors, the private customization of home appliances can not reach the real private customization like high-definition clothes at present, but the universal customization can still be realized. For example, designing products specifically for the needs of a small group of people, smart enthusiasts focus on developing cool intelligent functions, so that they can greatly enjoy the fun brought by intelligence during use; For the elderly with low acceptance, it should not be difficult to design simple and easy-to-operate functions to make them as convenient and fast as possible in the use process. I don't think the private ordering of household appliances is very reliable. Do you think you can tell the appliance manufacturer that I want to buy a double-door refrigerator, but my kitchen area is too small. You'd better produce a refrigerator with a smaller area. But I like ice cream very much, so the refrigerator has more freezing space. I think it is particularly troublesome to adjust the temperature of the fresh-keeping space of the refrigerator frequently. Please build more temperature control zones in the refrigerator. In personal tailor like this, technology is hard to achieve even after years of development.
