Silly Invention: Mobile Toilet

Admin October 02, 2026

"Er Ge's Invention of the Mobile Toilet" is a creative plot presented in an exaggerated manner in a silly animation, centered around addressing the shortage of toilet resources while incorporating real-world examples to showcase the humorous extension of this idea.

Invention Background and Process in the Animation

In the animation, Er Ge faces long queues at the school's men's restroom, which has only three stalls, leading to embarrassing situations like being unable to hold it in during diarrhea. To solve this problem, he initially tries to "monopolize resources" by locking the stalls and charging for their use, but this incurs the wrath of others and leads to retaliation (such as being locked in the restroom). After being suspended from school for half a month, Er Ge has a sudden inspiration and invents a "mobile toilet" by mounting a simple toilet on a tricycle, offering services everywhere. For example, he once rode the tricycle to take "me" to school, but due to a steep slope, the tricycle overturned, and "we" fell into a ditch, even causing a surge in hospital visits in a comedic incident. This plot highlights the "portability" and "instability" of the mobile toilet through exaggerated comedic techniques.

Similar Inventions and Scenarios in the Real World

Apart from the animation, in reality, some automakers have attempted to integrate the concept of a "mobile toilet" into car design. For instance, Seres has obtained a patent for a "vehicle-mounted toilet" that uses a sliding rail toilet, which can be hidden under the seat; Jishishen Auto has transformed the center console into an emergency toilet, equipped with a folding toilet seat and deodorizing gel. These designs primarily target the urgent need for restrooms during highway traffic jams or in remote areas, attempting to solve temporary toilet needs through interior space optimization. However, netizens joke that "after refrigerators, TVs, and sofas, toilets are now being brought into cars," reflecting that while such inventions are practical, they still carry a certain degree of humor due to scenario limitations.

Comparison and Inspiration Between Animation and Reality

The mobile toilet in the animation is presented in an exaggerated manner, emphasizing the "silly" nature of the idea; whereas real-world inventions focus on practical scenarios and technical feasibility. Both reflect the趣味性 (humorous aspect) of the "mobile toilet" idea, but the animation emphasizes entertainment, while reality focuses on solving practical problems. This comparison not only showcases the diversity of creativity but also reflects the differentiated thinking approaches to the same problem in different fields.
