Answer 1

Poka-yoke is a Japanese term and is a method that refers to mistake-proofing in any process that helps an equipment operator to avoid mistakes. Its purpose is to eliminate product defects by correcting, preventing or by drawing attention to human errors as they occur. In this problem, a mother is concerned regarding correct temperature of milk because she uses a traditional thermometer which needs to be separately inserted into milk to check the temperature. This is unhygienic and may not guarantee correct reading as done by the mother. Therefore, a new bottle has been designed in which there is temperature sensor to detect the temperature, digital display and temperature button to enable the sensor. This will maintain hygiene of milk and also the mother's problem will be solved. When she will pour milk in this bottle, temperature sensor will sense the temperature and display it accurately. It also has a nipple that will help the child to suck the milk comfortably.
