Chinese Automaker Develops Onboard Toilet for Cars

Sometimes, nature calls unexpectedly, and Chinese car manufacturer Seres is aiming to address that with a unique invention. They’ve patented an “onboard toilet” that conveniently slides under the seat, enabling drivers and passengers to use it without needing to pull over. A built-in fan aims to tackle any unwanted odors.

According to a recent report from the BBC, Seres filed a patent in China on April 10, explaining that this feature is intended to cater to “users’ toilet needs during long journeys, camping, and even sleeping in their vehicles.”

Based in Chongqing, Seres has yet to announce any vehicles featuring this toilet system, and it’s still uncertain if such models will be produced in the future. Regardless, the company is eager to share information about this new patent.

The documentation outlines how the toilet mechanism can be activated, either through a manual push or even by voice command. When activated, the toilet slides out from beneath the passenger seat. Users can simply push the seat back or say “activate toilet function” to access it.

Moreover, the setup includes a fan and exhaust system to help dissipate odors, as noted in the intellectual property filing reviewed by the BBC.

Waste collects in a tank that will require periodic manual emptying. Interestingly, the design also features a rotating heating element, which helps evaporate liquid waste and dry out solids. When not in use, the toilet remains entirely concealed under the seat, utilizing space effectively.

This approach seems quite novel within the automotive industry. However, there are voices of caution. Critics highlight that, despite the design’s assurances of sealed lids and deodorizing features, many potential users might find it difficult to overcome the psychological hurdle of using a toilet in a vehicle and the inherent privacy concerns.
