Mobile Toilet Open-Top Design
The open-top design is not common in mobile toilets, and only some products may have similar features. The following analysis is conducted from three aspects: structural characteristics, functional requirements, and market product conditions.

Structural Characteristics and Functional Requirements Determine That Open-Top Design Is Not Mainstream
The core structure of tent-style mobile toilets is centered around the tent, with temporary space constructed using supports and waterproof fabrics. The original design intention is to balance portability and basic usage functions. For example, they can be quickly deployed at large-scale events (such as the commemoration of the 80th anniversary of the victory of the Chinese People's War of Resistance Against Japanese Aggression and the World Anti-Fascist War) to meet the toilet needs in areas with dense crowds. In such scenarios, the toilets need to have privacy protection (such as enclosed structures and anti-peeping fabrics), environmental adaptability (waterproofing, rain protection, and wind resistance), and sanitary conditions (odor control and barrier-free facilities). If an open-top design (i.e., without a top or side enclosures) is adopted, although it may offer a wide field of view, it will directly compromise privacy protection. Moreover, it cannot be used normally in rainy days, strong winds, or extreme weather conditions, and may even affect the surrounding environment due to odor diffusion. Therefore, it does not meet mainstream functional requirements.
The Open-Top Feature Is Only Implicit in Some Designs in Market Products
Although simple toilet tents and related outdoor products on the market emphasize portability and mobility, most products achieve functional balance through fully enclosed or semi-enclosed structures. For example, some products use transparent or semi-transparent fabrics to improve lighting while still retaining top and side enclosures. A few products may achieve a "semi-open-top" effect through adjustable curtains or mesh structures, but the applicable scenarios (such as outdoor showers and changing rooms) need to be clearly stated, and prices vary greatly depending on materials and functions (ranging from tens to hundreds of yuan). There is no clear evidence indicating that the open-top design is a common feature of mobile toilet tents. It is only implicitly mentioned in some product descriptions that the tent structure may offer a field-of-view advantage, but this comes at the cost of sacrificing privacy or environmental adaptability.
The Open-Top Design Should Be Selected with Caution in Practical Applications
If users require an open-top mobile toilet, they need to clarify the usage scenario and priority of requirements. For example, in outdoor activities without privacy requirements and with mild climates (such as temporary rest areas at music festivals), a semi-open structure can be considered. However, in public events, urban areas with dense crowds, or scenarios that need to meet barrier-free and sanitary standards, fully enclosed tent toilets should still be selected to ensure functionality and compliance.
