"The Ten Best Invention Awards", The Grass Root Invention Of Spring Skates Is Among Them.

It is a common practice to publish "the ten best invention awards" every year in magazines.

2012 is its sixth year. The award is known for its strict approval process. What are the annual "gifted" inventions? What are the abilities to solve serious problems? What are the products that will soon become real world? Many people are looking forward to this list.

Interestingly, although the selection criteria are very serious, in the final entry list, they are often called "grass roots" full of flavors. Because many award-winning designs are very close to the minutiae of work life, and may even be trivial enough to make you think it was invented just to laugh at bloggers.

But they are still aimed at maximally helping people, or highlighting an unprecedented idea of invention.

In any case, according to popular science, this year's selection process is still "grim". In the "Wan Zhong election ten" arena, it has been "standing" to the last ten players.

Let's see if they have maintained the standard of the award.

Five thousand years.

David brevsky's main job is to manage apartments near Toronto, but he will also do his favorite gadget creations in any spare time, such as solar energy smoke detectors or skin cream that removes old plaques.

In 1998, when he was skating at the local skating rink, a new idea suddenly caught his mind: could he invent a spring skating shoe that could make skaters more free to control their movements?

Although the difficulties of the research process are beyond imagination, when the Patent Office tells that no one has ever had the same idea as himself, he feels the excitement of an innovator.

It can be said that

No matter what is the earliest use of whale skins and skins, or the use of carbon fiber and stainless steel, the basic structure of skates has not changed much over the past 5000 years: feet boots, skates and ties that bind them.

Brewer added a new element to these three parts -- springs.

In the prototype shoes he made, brew placed two compression springs in the two holes which were originally installed in the toes and heels, and then put the skates on.

So when the skater starts to move his feet, the springs will be compressed, and the skates will also earn a few millimeters in the skates accordingly.

When the skater raises his foot, the spring releases the energy stored before, and the skates return to the original position, so the skaters gain extra thrust.

Unfortunately, he himself did not have enough money to hire professionals to conduct further studies such as fatigue tests.

Fortunately, many people have already seen business opportunities. Now, Mike Austin, a sports physiotherapist, said that after putting on this new shoe, athletes need toes only to exert their strength, instead of using the whole sole of the foot to move forward, and skating for 20 minutes without feeling tired.

This can effectively reduce muscle and joint injuries.
