Father and son invent toilet that saves $120 million thanks to surprising principle

Save 83% water

At the workshop introducing "Invention solution for mechanical-electrical system to control flushing toilet" held at the Center for Information and Statistics of Science and Technology (Department of Science and Technology of Ho Chi Minh City) recently, Mr. Nguyen Van Nam (60 years old) poured a bucket of marbles into the automatic toilet he invented.

Then he poured a small cup of water (about 200ml) in and pressed the switch. Quickly, the balls were pushed down in less than 8 seconds.

The automatic toilet invented by electrical engineer Nguyen Van Nam saves up to 83% of water compared to conventional toilets (Photo: Nguyen Vy).

This is a product that Mr. Nam and his son have researched and invented for more than 9 years. He added: "According to calculations, a family of 5 people only needs 14m3 of water/year for this type of sanitary equipment compared to 86m3 of water consumed by other types of normal toilets. For businesses, the savings can be up to billions of VND per year."

Applying 25 years of experience working in the shipping industry, Mr. Nam explained that water-saving toilets operate based on the principle of the human rectal system with components such as one-way valves, devices that push waste out...

The components operate according to an electronic circuit that Mr. Nam designed, helping to optimize water usage and prevent odors.

Unlike conventional toilets, Mr. Nam removed the water tank in his product. Water will be pumped continuously during the flushing process. It only takes 6-8 seconds for the user to press the flush button directly from the water pipe into the toilet.

The S-shaped exhaust system below was replaced with a flexible, flexible, corrugated straight pipe. Along the pipe, Mr. Nam arranged additional clamps that opened and closed continuously, placed at different positions to coordinate the activities exactly like the human rectum.

The device's control panel is designed as a small, compact handle box, with water discharge function at 3 levels: touch, no touch or automatic.

The control panel is designed simply, optimizing functions for users (Photo: Nguyen Vy).

When the waste collection process is finished, the toilet will automatically clean the bowl with different cycles after flushing.

According to Mr. Nam, eliminating many parts compared to conventional sanitary equipment will help commercialize the product better. In addition to 83% of operating water, the new device also saves more than 50% of raw materials and fuel for production, helping to reduce product costs.

Spreading the green living spirit to the world

It is known that Mr. Nam's product was granted a patent by the Department of Intellectual Property (Ministry of Science and Technology ) in February 2022.

Mr. Nam is even more proud because the product provides a safe solution for the environment, reducing impacts on nature.

So far, he has submitted patent applications to intellectual property agencies in the US and the European Union to protect product designs and ideas.

According to Mr. Nam, in 2014, his son Nguyen Nhat Quang (26 years old) and his father came up with the idea of ​​creating an automatic toilet, which helps optimize the function and at the same time saves a significant amount of water. The process of researching and experimenting encountered countless difficulties and obstacles because they had to calculate how to save the maximum amount of water, and not consume too much electricity.

Mr. Nam confided that the moment he attached the last screw to complete the product was when he felt happiest.

Mr. Nam was moved when recounting his journey of researching and inventing products over more than 9 years (Photo: Nguyen Vy).

"Having traveled to remote provinces such as mountainous areas and islands, witnessing people living in floods, toilets flooded, toilets unusable, I became more and more concerned, wanting to complete this device as soon as possible," Mr. Nam shared.

The 70-year-old electrical engineer hopes that Vietnamese products like the device he and his father created can spread widely.

"In Vietnam alone, if this type of sanitary equipment is widely applied, 120 billion cubic meters of water can be saved each year, equivalent to 120 million USD," Mr. Nam asserted.

According to Mr. Tran Giang Khue, Head of the Intellectual Property Office in Ho Chi Minh City, this invention brings many advantages and is especially useful for daily life as well as being environmentally friendly.

"The invention has great advantages such as high applicability and easy installation. Above all, it also helps save production materials and domestic water. The product also contributes to protecting the environment and spreading the spirit of green living. In addition, when commercialized, the product has high market value," said Mr. Khue.
