Abstract
Official abstract text for this publication.
It is provided a computer-implemented method for designing a folded sheet object, comprising the steps of providing (S 10 ) panels separated by bend lines, including at least four adjacent panels forming a cycle and separated by concurrent bend lines, with predetermined angles between successive bend lines; and determining (S 20 ) a control law linking the angles between the adjacent panels of the cycle, as a function of the predetermined angles between successive bend lines. Such a method improves the design of a folded sheet object.
First claim
Opening claim text (preview).
What is claimed is: 1. A computer-implemented method for designing a folded sheet object of a computer-aided design (CAD) system, comprising the steps of: providing (S 10 ) structured data that define panels separated by bend lines, including at least four adjacent panels forming a cycle and separated by concurrent bend lines, with predetermined angles (α i ) between successive bend lines; determining (S 20 ) a control law linking the angles (β i ) between the adjacent panels of the cycle, as a function of the predetermined angles (α i ) between successive bend lines, the control law used as a closed form formula; and adding data that define the control law to the structured data; wherein the control law fixes, given predetermined values for a number of the angles (β i ) between pairs of the adjacent panels (φ), the number being equal to a degree of freedom ( 1 ) of the cycle, values for the angles (β i ) between other pairs of the adjacent panels (ψ), and further wherein, when the cycle has four adjacent panels, the control law comprises the solution of an equation of the type F(ψ,φ)=0, where ψ and φ are the angles between successive pairs of the adjacent panels and φ is predetermined, the angles (β i ) between the two other pairs of adjacent panels of the cycle stemming from said solution, the angles (β i ) between the two other pairs of adjacent panels of the cycle being directly computed from Ψ and φ; wherein the equation is: F ( ψ , ϕ ) = k 1 - k 2 cos ψ + k 3 cos ψcos ϕ + k 4 cos ϕ - sin ψ sin ϕ with : k 1 = cos α 1 cos α 2 cos α 4 - cos α 3 sin α 2 sin α 4 k 2 = cot α 4 sin α 1 k 3 = cos α 1 k 4 = cot α 2 sin α 1 and α i(i=1 . . . 4) are the predetermined angles (α i ) between successive bend lines, where ψ is the angle between the pair of the adjacent panels corresponding to α 1 and α 2 , and φ is the angle between the pair the panels corresponding to α 1 and α 3 . 2. The method of claim 1 , wherein, when the cycle has more than four panels, determining the control law comprises: partitioning the panels into four groups; and for each group which comprises at least two panels, determining a virtual panel that forms a cycle with the panels of the group, thereby forming a virtual cycle of four adjacent panels that each correspond to a respective group, the virtual panel being a theoretical panel that would form a cycle of adjacent panels with the panels of the group; and the control law comprises the solution of equ
