Design concept of capsule hotel

This kind of hotel once became a fashion. At the craziest time, Japanese newlyweds went to this hotel for a day and experienced "intimacy" (this space is of course intimacy-as long as it doesn't suffocate). However, it gradually lost its appeal. The author once went to live for a day out of curiosity and felt that the problem was very big. First, the ventilator is too noisy, and the air is dirty and stuffy. Second, the "door" is a curtain, which has poor privacy and great noise interference; Third, the equipment is outdated, and there is not even a DVD, let alone internet access equipment. Feeling, on the one hand, this is caused by the requirement of extreme cost saving. On the other hand, since the "capsule hotel" appeared, the Japanese have not improved it and stuck to the rules. It is normal that the equipment in the 1970s can't meet the needs of people in 2 1 century. If converted into an astronaut-style closed cabin, equipped with air conditioning and new electronic equipment, it may be rejuvenated in Japan or other countries.
