Foreign Open-Air Mobile Toilets
Foreign open-air mobile toilets mainly include two types: fixed open-air toilets and portable mobile toilets, each with distinct design features and application scenarios.
Open-air toilets exist in the Netherlands, featuring gender-differentiated designs. Men's toilets are open and unobstructed, a design likely related to local culture or usage scenario requirements, such as quickly addressing men's restroom needs in specific public areas. Women's toilets are equipped with doors to ensure the privacy of female users. In Amsterdam, the presence of a tram station beside open-air toilets makes them a unique element in the urban landscape, meeting functional needs while integrating with urban transportation facilities.
Portable mobile toilets are another typical form, exemplified by the leaf-shaped product designed by German designer Eva Tint. Its core material is a special eco-friendly material. When folded, it measures approximately 12×28 centimeters and can be easily stored in a woman's handbag, demonstrating its portability advantage. It contains a super-absorbent agent inside that converts liquid into gel and prevents leakage, with usage instructions printed on the bottom to ensure user convenience. This design first gained attention during the 2008 European Cup due to soccer fans' restroom needs and was mass-produced by a German company in 2009, entering the European market in sets of three at a price of 4.5 euros each.
Initially targeting female users, it aimed to alleviate long lines at public restrooms and gradually expanded to scenarios such as car travel and outdoor gatherings. Cleaning wipes are provided for use, and after disposal, it can be treated as ordinary garbage, meeting environmental requirements. As application scenarios expanded, its convenience and practicality were recognized by more male users, and the user base gradually grew.
Both types of open-air mobile toilets embody a combination of functionality and scenario adaptability: fixed open-air toilets focus on rapid deployment in public areas, while portable mobile toilets emphasize personal flexibility and eco-friendliness, jointly meeting restroom needs in various scenarios.
