Background Research

Water scarcity is a global issue. Currently, the Horn of Africa is facing its worst drought in over 40 years. Four consecutive failed rainy seasons have led to mass displacement and significant livestock losses. Meanwhile, in many other regions around the world, even where rainfall is adequate, the lack of infrastructure prevents people from accessing clean water. Contaminated sources often lead to the spread of diseases and other health problems. This design aims to provide a feasible solution to these challenges.

Through extensive research and literature review, we identified a new material called SHPFs—super hygroscopic polymer films—that can absorb moisture from the air, even at low humidity levels. The material is highly efficient: as shown in the graph above, it can collect over 4.125L of water per kilogram per day at a relative humidity of just 15–30%. Click the link to learn more.

Product Design

To maximize the contact area between the SHPFs film and the air, the product draws inspiration from origami, using a foldable mesh structure that enhances both aesthetics and efficiency. Standing at around 40cm tall, it can be easily folded and transported. The body is made from frosted acrylic panels, complementing the film material. Thanks to its cut-and-assemble design, it can be flat-packed to minimize production and shipping costs. The overall form resembles a blooming flower, which is why we named it Oasis Flower—a symbol of hope.

Usage Process

The usage process consists of three main steps, as shown in the diagram: First, the product is unfolded to collect moisture from the air. After a period of absorption, it is closed and placed under sunlight. The heat causes the water in the material to evaporate and flow along the curved surfaces into a container on the right. Once evaporation is complete, the user can remove the container to retrieve clean water. The product can then be reopened to repeat the cycle.

The process is simple and intuitive, allowing even women and the elderly to operate it independently. With no need for electricity and low production costs, the product holds strong potential for large-scale deployment.
