The deformable sofa is the most noticeable display of this year's Geneva invention exhibition.

Gerald Samir, spokesman for the forty-fourth Geneva international inventions exhibition, said that despite the Internet, we could easily access many items, but this annual exhibition still has its special features.

"Here, you can see inventors from all over the world, and you can talk to them directly," he said.

This year's invention exhibition is held at the Palexpo Convention and Exhibition Center of Geneva Airport. It is estimated that visitors will reach 59 thousand people, about half of whom are on business.

"Among them are professionals, investors who want to buy patents, and industrialists who study new products," Samir said.

Every year, this invention exhibition will sign a patent agreement worth tens of millions of dollars.

At the 2013 exhibition, a Romania team won a prize with a scanner that could detect illegal weapons or weapons hidden on planes, so that the team members became millionaires in one fell swoop.

Later they began to build factories in St.

According to the organizers, the invention exhibition will be more exciting in the future.

They said in a press release: "half of the items and technologies that we may use in 10 years" have not yet been invented.

This exhibition is particularly prestigious in developing countries, and many developing countries provide travel subsidy to the best inventors in the country to ensure that their national style is fully displayed.

More than half of the exhibitors are from the Middle East and Asia.

A French inventor has exhibited a new neck support this year for hairdressers to wash their hair at home.

With the equipment he designed, the garbage bags could be tightened enough to reduce the frequency of changing trash bags.

The Geneva International Invention Exhibition will be concluded on the 17 th.
