A method is provided for the creation of an addendum for use in the design and production of sheet metal formed components, which method uses a sectionless approach. In a preferred approach, elevation curve (EC) lines are established relating to the component (ECc) and binder (ECb), and it is these lines which are used to design the addendum. Additional EC lines (EC1, EC2, EC3, etc.) can be added to modify or optimize the addendum design. The spaces between the EC lines are filled using various parameterized filling techniques so as to provide the addendum design. Optimization of the addendum can be achieved by modification of the various EC lines, so as to modify or control the various design parameters, in accordance with various quality or design criteria. A more rapid, and less complicated approach to addendum design is provided.

Certain exemplary embodiments can provide a method comprising, via computer aided design, designing parts of an object that comprises an outer shell and an inner body, at least one of the outer shell and the inner body defining a specific volume negative space relief. In certain exemplary embodiments, the specific volume negative space relief defines a channel constructed to pass at least one of a fluid and a gas.

Mating bevel gears generally include a pinion gear having a body that rotates about an axis and a side gear having a body that rotates about an axis that intersects the axis of the pinion gear. Pinion gear teeth of the pinion gear have a side that defines a curvature with an involute section through which a pitch line extends and a parabolic shape between the pinion gear teeth. Side gear teeth of the side gear have a side that defines a curvature with an involute section through which a pitch line extends and a parabolic shape between the side gear teeth. The curvatures on the pinion and the side gear teeth cooperatively define a controlled relative radius of curvature section except where the involute sections are located. The controlled relative radius of curvature section defines a sum of values of radius of curvature at a point of contact between the curvatures of the pinion gear teeth and the side gear teeth. The sum has a constant or decreasing value.

In the field of protective equipment, a method can be provided for design and manufacture of protective equipment that allows for a degree of customization to provide enhanced performance characteristics without incurring high cost. In some examples, the method includes a method of determining a mold for a body part including the steps of inputting body part information, searching a database of existing anatomical components and selecting components that most closely match the information, searching a database of body part models and selecting at least one body part model that closely corresponds to the selected components, creating a body part model from the selected components, comparing the two models and determining which model is most appropriate and using a mold associated with that model.
