Mobile Toilet Design

The design of mobile toilets needs to comprehensively consider functionality, mobility, environmental protection, and aesthetics. The following explains from three aspects: design types, structural components, and design principles:

I. Common Design Types

1. Water Storage Tank Modification Type
   Split a water storage tank in half and fix universal wheels at the four corners of a wooden board for mobility. Use wooden strips to fix them on the upper side of the tank to increase height. Open a door on the side and install sponge strips to form a door frame, and embed plastic soft panels to form walls. The upper half of the tank serves as the roof. Open a hole at the bottom to install a drain pipe to form a floor drain. Open holes on the side and bottom to connect interfaces, and place a plastic bucket as a small water storage device. Internally, equip with a water pipe-made bath heater, a showerhead connected via a three-way joint, a toilet, and a water tank. Connect the drain pipe to a sewage tank and extend the water pipe to the door as the inlet pipe for the sink.

2. Modern Integrated Type
   Adopt a beige exterior wall paired with an orange curtain wall. Internally, set up multiple male and female toilet stalls. The overall decoration style is simple and modern, suitable for use in public places.

3. Innovative Shape Design Type
   For example, a butterfly-shaped design, using a galvanized steel frame structure, with a color-blocked exterior wall design, equipped with KFC double doors, and a reasonably laid-out interior that combines aesthetics and practicality.

II. Structural Components

Mobile toilets typically include fecal sewage storage tanks (or disposal devices), floor slabs, sanitary ware, walls, washing equipment, water tanks, roofs, and mobility devices. They can be classified by structural form into single-unit structures (independent units) and composite structures (multi-unit combinations); by mobility method into lifting/handling types and powered/towing types; and by sewage treatment method into water-flush types, waterless suction types, circulating water-flush types, and dry-packing types.

III. Core Design Principles

1. Mobility Convenience
   The overall structure should be lightweight, with priority given to lightweight and durable materials (such as aluminum alloy and plastic). Control the height and width to adapt to different transportation vehicles. The mobility devices (such as universal wheels and towing devices) should be well-designed to ensure stability.

2. Environmental Protection and Durability
   Use water-saving sanitary ware, and the sewage treatment devices should meet emission standards. The materials should be corrosion-resistant and easy to clean to extend the service life.

3. Functionality and Humanization
   The internal layout should be reasonable, meeting basic usage needs (such as ventilation, lighting, and privacy protection). Accessibility facilities can be added to reflect humanitarian care.
