Guangxi Mobile Toilet Design
The design of mobile toilets in Guangxi exhibits diverse characteristics, encompassing various aspects such as structure, usage methods, and flushing systems, yet it also faces some controversial design issues.
In the design of multi-person mobile toilets, multiple independent compartments are typically installed inside, each equipped with a toilet, flushing system, and ventilation device. Modular design is adopted, with the main frame constructed from metal or high-strength engineering plastics, providing wind resistance and rust prevention capabilities. The compartment doors are often made of fire-resistant materials, and the interior floors are covered with anti-slip mats. Additionally, elderly-friendly facilities such as handrails are installed to ensure the safety and convenience of users. The core water supply and drainage system is integrated beneath the chassis, enabling flushing and waste collection through pre-installed sewage tanks or external sewage pipes. Some high-end models are also equipped with independent odor treatment devices to effectively improve the internal environment of the toilets.
In terms of usage methods, there are direct-discharge and storage-type toilets. Direct-discharge toilets are connected directly to municipal sewage networks via hoses and are suitable for sites with fixed sewage connections. Storage-type toilets, on the other hand, feature large internal sewage collection tanks that are periodically cleaned by sewage suction trucks, making them ideal for temporary sites without sewage facilities. Regarding flushing methods, there are water-flush and foam-flush types. Water-flush toilets are more common, while foam-flush toilets utilize a small amount of water and foaming agents to generate foam that lubricates the pipes, saving water and effectively suppressing odor diffusion.
Furthermore, there are mobile toilets designed for three people, with restrooms on both sides and a shower room in the middle, meeting various usage needs.
However, the design of mobile toilets in Guangxi also faces some controversies. For example, at a public toilet in Hechi, Guangxi, the doors of the squatting compartments face directly towards the entrance, with wide gaps in the door panels, seemingly allowing outsiders to peek inside, which makes female users feel insecure. The root of the controversy lies in the misalignment between design objectives and user experience. The spatial layout of this public toilet is too straightforward, with direct access to the field of vision upon opening the door, and the squatting compartments facing the entrance with almost no visual barriers or transitions, affecting the user experience.
