Car as a Mobile Toilet
The design of cars as 'mobile toilets' does exist, but it is mostly for specific scenarios or innovative designs, rather than a mainstream function. Here is a detailed analysis:
1. Seres's In-Vehicle Toilet Patent: Innovative Design for Emergency Scenarios
In April 2024, Seres was granted a utility model patent for an 'in-vehicle toilet and vehicle'. Its core design features a sliding rail structure hidden beneath the driver and passenger seats. The device is equipped with a 5L sealed waste collection tank, a negative pressure deodorization system, a constant temperature heating function, and disposable waste bags, addressing the challenge of using the restroom during long drives or highway traffic jams. Despite sparking controversy, groups such as family road trippers and off-road enthusiasts consider its emergency value significant, especially in remote areas or medical rescue scenarios.
2. HiStone's In-Vehicle Toilet Accessory: Modular Emergency Solution
HiStone once introduced an in-vehicle toilet accessory that installs in the central storage compartment. Users can simply lift the lid and add a toilet seat cover to use it. Positioned as an emergency tool, this accessory emphasizes portability and temporary use, suitable for short trips or sudden needs. Its design does not integrate complex systems, keeping costs low, but relies on users for active installation and cleaning.
3. Negative Case of Shared Cars: Operational Management Failure
Some shared cars have been used as makeshift toilets due to user misconduct, leading to severe hygiene issues. Such cases represent operational management failures rather than design intentions. Automakers have gradually reduced such problems by strengthening user credit management and installing in-car surveillance.
4. Boundaries of Functional Expansion: Excretion Function Remains a Minority Exploration
Some automakers expand car functions through innovative designs, such as the IM LS9's trunk shower function and the Landian model's trunk induction cooker. However, excretion functions remain a minority exploration due to complex issues involving hygiene, sealing, and odor control. Currently, cars are more inclined to develop into 'mobile living spaces' rather than fully replacing fixed sanitation facilities.
Summary: The design of cars as 'mobile toilets' primarily targets specific needs or extreme scenarios and has not yet become an industry mainstream. Its development is constrained by factors such as technological costs, user acceptance, and hygiene management. In the future, it may further explore application potential in emergency scenarios through modular design or integration with intelligent sanitation systems.
