Invention of Mobile Toilets in Kaili, Guizhou

Kaili in Guizhou has achieved results in mobile toilets, including the invention of portable toilets and the setup of mobile public toilet facilities. Details are as follows:

Invention of Portable Toilets

Yu Kaisheng from the residential area of the Kaili Highway Bureau invented a portable toilet and received a utility model patent certificate issued by the National Intellectual Property Administration. His motivation for the invention stemmed from a severe traffic jam on the expressway during a National Day holiday. He witnessed the embarrassing situation where people had to relieve themselves on the spot due to the lack of toilet facilities. This portable toilet has several notable features:

• Portability: The foldable design is a major highlight. When in use, one simply needs to take out a light-green object from a small bag, open it, and it transforms into a bucket-like structure, providing a convenient space for the user. After use, it can be folded back into a super-thin object slightly larger than an adult's cotton hat, making it easy to carry. Whether placed in a backpack or held in hand, it does not take up much space, facilitating its use during travel.
• Functionality: The internal space is large enough not only to meet the needs of relieving oneself but also for changing clothes. Additionally, it is equipped with a ventilation device, effectively preventing the risk of suffocation due to the enclosed space and ensuring the safety of the user.
• Privacy Protection: When in use, this portable toilet can wrap most of the user's body, providing a relatively independent and private space. It effectively protects personal privacy and avoids the embarrassment of relieving oneself in public places.

Setup of Mobile Public Toilet Facilities

Kaili has set up mobile public toilet facilities, mainly distributed in areas with high pedestrian traffic, such as commercial districts, parks, and transportation hubs. It also takes into account relatively remote public places, and the placement of each facility is based on on-site inspections. Their design and structural features include standardized design, primarily using lightweight materials for easy transportation and installation. The exterior colors are mostly light shades, harmonizing with the environment. The internal space layout focuses on practicality, with basic configurations such as sinks, mirrors, and hooks. Some also consider accessibility needs. The design emphasizes durability and ease of cleaning, with waterproof and rust-proof materials. In terms of sanitation maintenance and management, daily cleaning includes floor sweeping, facility wiping, and garbage removal, using neutral cleaning agents. High-contact areas are regularly disinfected. Cleaning staff operate on fixed shifts, garbage bags are replaced promptly, and maintenance records are made publicly transparent. In addition, environmental protection and energy-saving measures are taken, such as the use of water-saving flushing systems in some models, low-energy LED lighting, waste classification and disposal, the selection of environmentally friendly cleaning products, and modular design for easy recycling or modification in the later stage.
