Optimized sports article
Embodiments of the invention concerns a method of designing a sports article, including: (a) scanning at least one body part of at least a first person; (b) creating a first digital model of the body part of the first person; (c) creating a digital model of the sports article; (d) digitally arranging the digital model of the sports article on the first digital model of the body part, while allowing the digital model of the sports article to stretch digitally and (e) digitally modifying at least one property of the digital model of the sports article based on the first digital model of the body part and the digital model of the sports article.
1. A method of designing a sports article for use in an athletic activity, comprising:
creating a digital model of the body part of a first person;
creating a digital model of the sports article;
digitally arranging the digital model of the sports article on the digital model of the body part, while allowing the digital model of the sports article to stretch digitally; and
digitally stretching the digital model of the sports article based on an elastic modulus of the sports article in the digital model,
wherein digitally stretching the digital model of the sports article comprises digitally applying a force to the digital model of the body part to increase a circumference of the digital model of the sports article,
wherein a circumference of a first portion of the digital model of the sports article stretches by a first fraction of an unstretched circumference of the sports article, and
wherein a circumference of a second portion of the digital model of the sports article stretches by a second fraction of the unstretched circumference.
2. The method according to claim 1 , wherein the first portion is a top portion and the second portion is a bottom portion of the sports article, and
wherein the first fraction is smaller than the second fraction.
3. The method according to claim 1 , wherein the force applied to the body part depends on the elastic modulus of the sports article.
4. The method according to claim 1 , wherein digitally stretching the digital model of the sports article further comprises digitally reducing the force applied to the digital model of the body part, and
wherein the force is a vertical shear force.
5. The method according to claim 4 , wherein reducing the force applied comprises reducing a thickness of a top portion of the sports article as compared to a thickness of a bottom portion of the sports article.
6. The method according to claim 1 , wherein digitally stretching the digital model of the sports article further comprises varying a width of a bottom portion of the sports article along a circumference of the sports article to reduce the drag force.
7. The method according to claim 6 , wherein a front portion of the bottom portion comprises a smaller width as compared to a rear portion of the bottom portion.
