Problems solved by technology

To date, last mass-production from plastic last block still generally follows the above mentioned twenty-one step sequence of operations which is conventionally of very high cost and is very labor intensive.
Another lengthy part of the mass-production process cycle that also requires skilled labor is sample shoes.
Conventionally, employing mechanical ...

Embodiment Construction

[0091] A preferred embodiment of the invention is discussed in detail below. While specific exemplary implementation embodiments are discussed, it should be understood that this is done for illustration purposes only. A person skilled in the relevant art / profession recognizes that other components and configurations may be used without parting from the spirit and scope of the invention.

[0092] An example embodiment of a blow molding apparatus 104 as an element of a custom-made shoe making system 102 in accordance with the present invention is illustrated in an exemplary shoe store layout 100 of FIG. 1. The store layout 100 can include a style selection area 106, which can allow a customer to choose a desired shoe style from a shoe catalog. To help the customer to choose a virtual pair of shoes, a camera 108 can capture lower body image (waist down) from different directions and can display each image on a separate display screen 110. After choosing the most suitable shoe style, the c...

Abstract

The present invention is an exemplary embodiment of the present invention is directed to a system, method and computer program product for creating a three-dimensionally reconfigurable cavity. The system can include a container that is configurable to create a three dimensional cavity. The system can be operative to form a footwear last in the cavity. The last can be formed from a plastic-like material. The system can include a blow molding apparatus having at least one directional deflector. The container can be capsule, hemispherical, cylindrical, or spherical-shaped. The system can include a container having holes to receive rods. The system can include an array of rods. The rods can be movable through the container. The system can further include rods that are threaded; gear-driven; coupled to a belt; coupled to a partial belt; or belt-driven. The cavity can be formed by an inner end of the rods. If more than one rod occupies a single point of the cavity, then only one rod participates in forming the cavity and other rods will not participate. Participating rods can be selected according to an optimizing module. The software module can determine an intersection of a rod with a digitized cluster of points representing a 3 dimensional surface. A method of forming a footwear last from a collapsible and expandable last is described.

Description

[0001] 1. Field of the Invention[0002] This invention relates generally to an apparatus, systems and methods for producing a shoe last and a related method of shoe construction.[0003] 2. Related Art[0004] As is apparent to those skilled in the art and the profession, "lasts" are fundamental to mass-production or custom-made shoe manufacturing, since lasts dictate the exact shape, size and fit of the shoes made on the lasts. Last design can depend on fashion trends as well as on anatomy of the foot.[0005] Conventionally, in a shoe mass-production process cycle, a last stylist must be able to forecast fashionable shoe styles about one year before the shoes are to be sold in shops. The stylist can create a model last using a 3D computerized last design software package and a Computer Numerical Control (CNC) cutting machine or a traditional method of carving the model last from a block of wood. The model is then prepared for turning a pair of sample size lasts. The sample lasts are used...
