Technological Innovation Invent Revolutionary Polyurethane Sports Shoes

Shoe-making machine maker BMS and BMS jointly developed 100% sports shoes production philosophy, which is made up of four polyurethane system materials.

Karsten Muller, the marketing manager of BMS, said that she had approached the company two years ago to share the idea of the concept shoe.

First, the stable layer is directly cast on the carrier cloth, and the outer liner is poured at the same time, and the outsole is directly cast on the pad.

After adding the three-dimensional layer and casting fourth layers, the production is finished.

The production of rigid parts of sports shoes uses the iron coating PE, while the production of shoe and shaft parts uses Bayflex S.

Muller said Bayflex S is a low-density polyurethane (220g/l), which can be made by physical foaming agent (small scale production) or carbon dioxide light weight technology.

The invention also used the combination of mold.

So that production can be completed on a machine.

Polyurethane must meet the functional requirements of each component.

The tensile strength of the first layer is guaranteed.

The comfort of the outer liner has better skid resistance and abrasion resistance.

Moreover, the combination of the double density system greatly reduces the external structural weight of the sports shoes, and has elasticity, so as to achieve the damping effect.

It is unnecessary to add adhesive to produce the sports shoes, and the whole production process is highly automated.

The custom machine was displayed and the production technology of the sport shoe was displayed, but it was not yet sold in the market.

The thinner lining is the carrier material of the prototype sample, not polyurethane.

Chris Harden, the development director of Jeremy Scheinberg and EA Sports of Orlando, worked together to develop robot TROBO for children. It not only chatted with children, but also shared many stories to keep children curious about the world.

In design, for children, the appearance of TROBO is like a doll, soft and comfortable. Apart from not hurting children, the most important purpose is to encourage children to interact with robots.

For example, touch it and hold it.

The most important purpose of TROBO is to guide children's behavior when chatting with children, and constantly stimulate curiosity to explore the world, such as science, technology, engineering and mathematics.

TROBO also has its own iPad App, which children can learn from App.

In fact, TROBO plays games with children every day, and then on iPad App there will be questions like "Happy Dictionary" so that children can challenge them.

Now, TROBO is still raising funds on Kickstarter. Now it has raised more than $290 thousand, far exceeding the initial target of $60 thousand, and they still have 15 days to go ahead.
