PROBLEM 5-Coin Machine Toilet.

The situation shows at Bowling,Mega mall.When want to enter the toilet,people must pay first.People must have enough money to pay.Although people pay to use toilet but toilet is not clean and kept performing.

THE PROBLEM IS:

1.Use cleaner to clean toilet every hours.

2.People must wait when the counter do not have people take care.

3.Manual.

4.Have time to pay when many people want to use toilet at the same time.

5.Have someone to take over at the counter.

So I think,Mega mall must have coin machine toilet.The machine function like users must insert a money and will then have 20 minutes of privacy in the toilet.The time remaining is counted down by a three-step audible warning and a blinking light,Once the person exits,the unit seals itself and begins a cleaning cycle.The unit will be able to detect if anyone remains in the unit past 20 minute mark and help could be summoned in the case of an emergency.

2.Use coin only.

3.not use a cleaner to clean the toilet.

4.Automatically and very fast.

5.Not use people to take this money.

6.Can detect and prevent damage or vandalism that occurs.
