Benefits of technology

This patent text discusses ways to distribute microwave energy throughout a chamber to cure a shoe sole. This can be done using additional elements like conducting deflectors and distribution plates to prevent over-curing and guide the energy to where it is needed. The customized energy distribution allows for a uniform cure of the shoe sole despite its non-uniform shape. Overall, the patent text outlines a technical solution for curing shoe soles and other parts using microwave energy.

Problems solved by technology

However, traditional systems and methods in microwave art do not provide customized energy distribution necessary to uniformly process a non-uniform workload such as encountered by a shoe part to be cured.
Traditional systems and methods are particularly disadvantageous when working with small chambers of a size required for a typical shoe part, as the traditional systems and methods applied to a small chamber may facilitate a blow torch effect.
Specifically, a blow torch effect may cause for a specific portion of material closest to a port to cure while leaving portions farther away from the port to remain uncured.
The blow torch effect does not allow for materials to be uniformly cured.

Embodiment Construction

[0060]Shoe construction in general, and the construction of athletic shoes in particular, can present a challenge due to the diversity of materials used in the construction of the shoes. Different types of materials may require different processing techniques to form into individual components, and further may be difficult to join together to create a fully assembled shoe. One particular example of these challenges of differing types of materials in a typical athletic shoe may be found in the sole section of a shoe. The outsole of a shoe may typically be formed from a rubber or other durable material that may withstand contact with the ground, floor, or other surface during wear. The midsole of a typical shoe, on the other hand, may often be formed from a different material such as a foam type of material, like for example, ethylene-vinyl acetate (EVA) foam, sometimes to referred to as phylon. While other types of materials may be used to form an outsole and a midsole than these exa...

Description

BACKGROUND OF THE INVENTION[0001]Shoes and similar items are often constructed from smaller parts made from rubber, foams, or other materials that require curing. Often, such parts are irregularly shaped and / or composed of more than one type of material. Curing irregularly shaped parts and / or parts made from different types of materials through the application of heat can be challenging, as attaining the desired temperature for different portions of a part with differing thicknesses and / or made of different materials can be difficult with traditional heating methods. Traditional heating methods for curing parts may use an oven, a heat press, or similar approaches to heat a part for a curing process. In addition to the difficulties of using ovens, heat presses, and the like to cure shoe parts due to energy distribution limitations, these methods also can be inefficient in their use of energy.BRIEF SUMMARY OF THE INVENTION[0002]The present invention generally relates to systems and me...
