How to Design Mobile Toilets
The design of mobile toilets can be considered from multiple aspects such as the utilization of water storage tanks, structural forms, mobility methods, and sewage treatment approaches.
Design Using Water Storage Tanks: First, use an angle grinder to split the water storage tank in half lengthwise. Fix universal wheels at the four corners of a wooden board for easy mobility. Next, take wooden strips and secure them to the upper side of the tank with self-tapping screws to increase height. Cut an opening on the side of the water storage tank and install sponge strips on both sides of the opening to form a door frame. Then, insert plastic soft boards between the wooden strips to create elevated walls. Place the upper half of the water storage tank on top of the wooden strips as a roof and apply white waterproof paint to the wooden strips for aesthetic enhancement. Afterward, use foam strips to拼接 (assemble) discarded honeycomb wooden boards to make a simple door. Cut a hole at the bottom of the tank and install a drain pipe to form a floor drain. Drill holes on the side and bottom of a plastic bucket and install direct connectors, then place the plastic bucket on the roof to form a small water storage device. Use water pipes to make a bath heater, install a tee connector below the inlet pipe and connect it to a showerhead, place a toilet over the drain pipe opening, install a water tank and secure it with glass glue, connect the drain pipe to a sewage tank, horizontally connect a water pipe to the tee connector on the outlet pipe and extend it to the doorway as an inlet pipe for a handwashing basin, and cut a hole in the door and install a connector.
Design by Structural Form: Mobile toilets can be divided into single-unit and composite-structure mobile toilets. Single-unit mobile toilets are relatively independent and have a simple structure, suitable for places with limited space or high flexibility requirements. Composite-structure mobile toilets are composed of multiple single units, offering richer functions to meet the usage needs of more people, and are suitable for large-scale events or densely populated areas.
Design by Mobility Method: There are lifting and handling-type mobile toilets, which are usually smaller in size and lighter in weight, facilitating movement by lifting equipment or manual handling. Powered and towed-type mobile toilets have their own power systems or can be moved by vehicle towing, offering a wider range of mobility and suitable for scenarios that require frequent relocation.
Design by Sewage Treatment Method: Mobile toilets can be classified into water-flush and non-water-flush suction-type mobile toilets, and circulating water-flush mobile toilets. Water-flush and non-water-flush suction-type mobile toilets treat excreta through water flushing or suction, providing a relatively high level of cleanliness. Circulating water-flush mobile toilets purify water through a circulation system for reuse, making them more water-saving and environmentally friendly.
