Toto worker creates mobile toilet system
TOSHIHIKO Yoshitomi, 36, who works in the Appliances Development Department of Toto Ltd, succeeded in October in developing a movable flushing toilet system – something previously considered difficult to realise.
It looks like a normal flush toilet with a warm-water cleaning nozzle. However, if set beside a bed, even elderly people who have difficulty walking would be able to use it.
Human waste and paper, and any odour, are flushed into the drainage through a hose measuring 2 centimetres in diameter and a maximum of 8 metres in length. The hose can be connected to the drainage system via a relatively simple procedure. The toilet is priced at 398,000 yen ($3,657) without tax.
Yoshitomi learned about the difficulty of toilet support while seeing his grandfather receive nursing care. There were many problems, such as odour, disposal, discomfort of diapers and a feeling of shame.
Yoshitomi joined Toto in 2006 after studying control engineering as a student. He actively engaged in development work, aiming to make both caregivers and receivers feel at ease.
Having matter break into pieces so that it can pass through the narrow hose proved necessary for realising a movable toilet system. During the first year and a half of his work,Yoshitomi investigated the hardness of his own solid waste by squeezing it in his hands and changing his meals on a daily basis. He was convinced that all human stools can be crushed into pieces using centrifugal force and water. Yoshitomi then developed a rotary crusher, taking cues from washing machines, and installed it on his toilet system.
Yoshitomi was moved to tears when he heard how happy a customer was. “Up until now, I’ve not been drinking enough water out of consideration for the difficulty my family members face in handling my waste,” the customer said.
“I will continue to improve the system to make it possible for anyone to use it without help,” Yoshitomi said.
