Hidden Aspect of Mobile Toilets

The 'hidden' aspects of mobile toilets can be understood from three perspectives: functionality, hazards, and design:

Hidden Functions of Mobile Toilets in Shanghai: Some mobile toilets in Shanghai feature a hidden function of built-in background music (BGM). This design breaks away from the traditional perception of mobile toilets as merely fulfilling basic excretion needs. By playing music, it offers users a unique and pleasant surprise, enhancing the overall user experience and transforming mobile toilets from purely functional facilities into spaces with emotional value, meeting users' psychological needs in special scenarios.

Hidden Hazards of Mobile Toilets in Fengtai District:

• Public Health Risks: If not cleaned and disinfected regularly, mobile toilets can easily breed E. coli, mosquitoes, and other pests. Leakage of excreta increases the probability of contracting infectious diseases through contact. In summer, poor ventilation exacerbates odor accumulation, and ineffective sealing of the septic tank can lead to the buildup of toxic gases, posing a serious threat to user health.
• Usage Safety Risks: The door locks are designed with simple snap-in mechanisms, which can easily fail or be accidentally pried open after aging, potentially trapping users inside. The floor's poor anti-slip performance increases the risk of falls for the elderly, children, or those with mobility issues.
• Facility Malfunction Issues: In old mobile toilets, damaged pipelines and sewage pipe leaks can result in slippery floors and increased odors. Mobile toilets with water and electricity functions may pose an electric shock risk. Malfunctioning night lighting can lead to trips or falls. Remote locations without surveillance also present personal safety risks.

Hidden Design of Seres' In-Vehicle Toilet: Seres has obtained a utility model patent for an 'in-vehicle toilet and vehicle,' with its core being a hidden in-vehicle toilet that can be stored beneath the seat. This design consists of a toilet body and a slide rail assembly. The fixed rail is installed above the toilet, and the sliding rail is connected to the seat structure, ensuring a stable connection with the vehicle seat. When in use, the toilet is extended from beneath the seat via the slide rail and pushed back to be completely hidden when not in use, saving cabin space and balancing practicality, privacy, and cleanliness. Additionally, it is equipped with disposable toilet bags and a sealing device for easy disposal without odor and easy cleaning, along with a foldable privacy curtain for added privacy. On April 10, 2026, the State Intellectual Property Office announced the grant of this patent, with the patent number CN224104011U.
