Rain Maker: A Water Purifier Powered by Human Strength

Designing a Sustainable Solution for Clean Water Access

The Rain Maker stands out from other water purifiers with its unique properties. The membrane filter, with a diameter of 0.4 microns, can remove 99% of bacteria and germs, ensuring safe drinking water. What sets it apart is the ability to use back flushing, which extends the lifespan of the filter, making it last longer than other purifiers. This feature is especially crucial in areas where water supply is scarce or unreliable.

The design of the Rain Maker also prioritizes convenience and accessibility. The product can store extra filters, allowing users to replace them easily when needed. Additionally, the purification process is user-friendly. To operate the Rain Maker, users simply let the undrinkable water settle in a separate container before filtering. The purified water is then collected in a collapsible plastic bottle, which can be easily transported.

One of the key challenges in designing the Rain Maker was finding the ideal shape for the membrane filters. Yong Sang Kang overcame this challenge by incorporating two cone shapes that are back to back, creating additional space for extra filters. Another challenge was the back-flushing process, which is essential for maintaining the efficiency of the filter. By turning the system upside down, users can easily clean the filter and extend its use-by date.

The Rain Maker has received recognition for its outstanding design and innovation. It was awarded the Silver A' Design Award in the Home Appliances category in 2012. This prestigious accolade is given to designs that demonstrate exceptional expertise and creativity, leaving a lasting impression on viewers.

With the Rain Maker, Yong Sang Kang has created a sustainable solution for clean water access. This innovative water purifier not only provides safe drinking water but also empowers individuals in underserved communities to take control of their own water supply. By harnessing the power of human strength, the Rain Maker offers a practical and efficient solution to the global water crisis.
