Chinese electric cars already have massages, karaoke and even a refrigerator. The next step is an under-seat toilet.

If you can’t hold back the urge to urinate while you’re in the car, the normal thing to do is wait until you make a stop at the next gas station to relieve yourself. That’s normal, and then there is Seres, the Chinese manufacturer of Aito cars, which has patented a rather peculiar solution: add a toilet integrated into the cabin that unfolds like a drawer. Exploring other areas. China has one of the most saturated electric car markets and competitive on the planet. Dozens of brands fight for the same type of audience and differentiation has become a race without limits: from massage seats and karaoke systems, even integrated refrigerators, giant screens…If everyone is doing the same thing in infotainment, why not explore the next territory? And this seems to be the conclusion reached by Seres, the Chongqing-based company that manufactures Aito brand vehicles. A portable toilet. According to they count From CarNewsChina, the Intellectual Property Administration of China granted Seres authorization for this patent on April 10. The device consists of a toilet integrated under the passenger seat that is extracted using a system of sliding rails (something similar to a drawer) manually or by voice commands. When not in use, it is completely hidden under the seat, without taking up additional space in the cabin. How it works inside. According to collect The BBC, which had access to the original document presented to the Chinese authorities, the system includes a fan and an extraction tube to evacuate odors to the outside of the vehicle. The waste is collected in a tank that must be emptied manually. In addition, it incorporates a rotating heater that evaporates urine and dries solids. Is for when the car is stopped. Before too vivid mental images arise, it is worth clarifying: the design is designed so that you stop as soon as possible and start with the task. According to CarNewsChinaSeres’ own engineers specify in the patent report that the objective is “to satisfy the needs of users during long journeys, camping or during prolonged stays in the vehicle.” Endless traffic jams, overnight stops or campsites without facilities are the intended use cases. It’s not as crazy as it seems. Toilets in cars are very rare, but it would not be the first time they have been seen in a car. In fact, just as account BBC, in the 1950s, a special version of the Rolls-Royce Silver Wraith already included a toilet under the back seat. There are also those who have modified their car to include one, such as this owner of a Toyota 4Runner. What Seres is proposing now is, in essence, a more technologically sophisticated version of an idea that already existed seventy years ago. Obstacles. Just because the patent exists does not mean that it will reach production. CarNewsChina points out several important technical obstacles, including integrating drainage pipes into compact chassis (especially in electric ones where the battery occupies a large part of the floor), guaranteeing the durability of the rails or achieving an airtight seal that prevents odor leaks. And then there’s the psychological barrier, which is basically convincing passengers that it’s perfectly normal to use the bathroom just inches from where the rest of the family sits. Seres is not going through its best moment. The company is going through a difficult time. According to data of China EV DataTracker, deliveries of Aito M9its high-end SUV, have fallen 44.2% year-on-year for three consecutive months. Seres and Huawei plan to soon launch a renewed version of the model to stop the decline. And in this context, these types of patents can help the brand, not even to make them a reality, but to try to generate conversation around its vehicles.
