Erge Invents Mobile Toilet
The reason Erge invented the mobile toilet was that there were too few toilet stalls in the school and long queues were common. After being frustrated by waiting in line when he had a stomachache, he first tried to lock some stalls and charge fees, but failed. Then, during his suspension from school, he invented the mobile toilet and used it to make a profit. Here are the details:

Reason for Invention
The school toilets had a serious design flaw. The number of stalls was far from sufficient to meet the daily needs of students, resulting in long waiting times for students when using the toilet. Erge had suffered greatly from this. Once, when he had a stomachache and urgently needed to use the toilet, he couldn't solve the problem in time due to the large number of people in the queue. This terrible experience became the direct trigger for him to invent the mobile toilet, prompting him to start thinking about how to solve the problem of long queues in the school toilets.
Early Attempt
Before coming up with the idea of inventing the mobile toilet, Erge made an inappropriate attempt. He took advantage of a loophole in the school toilet management and locked some stalls and charged fees from students who urgently needed to use them. Although this behavior satisfied his personal financial interests to some extent, it seriously infringed on the rights of other students, causing strong dissatisfaction and anger among his classmates. Eventually, his behavior was discovered by the school, and he received a suspension as punishment.
Invention Process and Result
After being suspended, Erge didn't get discouraged. Instead, he regarded this period as an opportunity for his invention and creation. After some thinking and design, he used a tricycle as a mobile carrier and invented the mobile toilet. This mobile toilet was flexible and convenient, and could be moved to wherever it was needed at any time. Erge rode the tricycle every day, carrying his mobile toilet around the school corners, providing services to students who urgently needed to use the toilet and charging a certain fee, thus achieving the goal of making a profit. His invention not only solved his own financial problems but also to some extent alleviated the problem of long queues in the school toilets.
