Design of Local Mobile Toilets

When designing local mobile toilets, you can refer to the following three creative solutions that combine practicality and innovation to optimize functionality:

1. Water Storage Tank Modification Solution This solution uses discarded water storage tanks as the core material to construct low-cost mobile toilets through structural reorganization. Modification Steps:

• Base Frame: Use an angle grinder to split the water storage tank vertically in half. Install universal wheels at the four corners of a wooden board to form a movable base. Fix wooden strips to the upper side of the tank with self-tapping screws to raise the overall height to ergonomic standards.
• Walls and Roof: Cut an entrance on the side of the tank, embed sponge strips to form a door frame, and cover the outside with plastic soft boards to create an elevated wall. Invert the upper half of the tank onto the top of the wooden strips as the roof and apply white waterproof paint to the surface to enhance weather resistance.
• Functional Modules:
  • Drainage System: Drill a hole at the bottom of the tank to install a drain pipe to form a floor drain. Drill a hole on the side to connect a three-way joint, extending it to the entrance as the inlet pipe for a handwashing basin.
  • Shower Module: Place a plastic bucket on the roof as a water storage device and connect it to a simple bath heater with a water pipe. Install a three-way joint below the inlet pipe and connect a showerhead to enable showering.
  • Toilet Module: Place a toilet and fix the water tank. Connect the drain pipe to an independent sewage tank to avoid environmental pollution.
  • Door Design: Use foam strips to拼接 (assemble) discarded honeycomb wooden boards to make a simple door. Drill holes in the door to install connectors, balancing privacy and ventilation needs.

2. Prefabricated Building Design Solution Adopt modular prefabricated components to achieve rapid assembly and flexible movement. Design Highlights:

• Appearance Optimization: Choose a warm-toned apple pod shape and use a two-color拼接 (spliced) design for the exterior walls to enhance visual appeal. Apply an anti-corrosion coating to the surface to extend the service life.
• Thermal Insulation Performance: Install a double-door structure in the middle and fill the door gaps with sealing strips to reduce heat loss. Fill the interior of the walls with polyurethane foam boards to improve thermal insulation.
• Signage System: Post luminous signboards in conspicuous positions, indicating "Mobile Toilet" and usage instructions for easy identification and operation at night.

3. PVC Pipe Mobile Toilet Seat Solution Utilize the lightweight and corrosion-resistant properties of PVC pipes to construct a movable toilet device. Production Process:

• Base Frame: Drill holes in four plastic caps, insert screws, and fix the wheel assemblies. Cut straight pipes and connect them to the plastic caps, using three-way joints to form a support frame. Insert the straight pipes into the reserved holes of the three-way joints to complete the base assembly.
• Functional Expansion:
  • Wheel Cover Installation: Vertically extend the straight pipes and connect them with elbow reducers to form the main structure of the toilet. Install wooden footrests and the base to improve user comfort.
  • Safety Reinforcement: Place sturdy wooden boards around and on top, and fix the backrest with screws. Install plastic pipes as handrails at the four corners of the front to prevent tipping.
  • Detail Handling: Cut a circular hole in the middle of the wooden board and wrap the edges with hoses. Apply waterproof paint to the surface for easy cleaning and maintenance.

Solution Selection Recommendations:

• Temporary Scenarios (such as outdoor events): Prioritize the water storage tank modification solution for its low cost and comprehensive functionality.
• Long-term Use (such as construction sites and scenic spots): The prefabricated building solution is more durable and offers better thermal insulation and aesthetics.
• Resource-limited Environments: The PVC pipe toilet solution is suitable for emergency or remote area deployments due to the easy availability of materials.
