Structure Working Process

A plain square sheet fold 3 times to an isosceles right triangle for cutting and unfolding.

Calculation 1: Cut Dieline Generation

Use linear function to represent the geometric shape of the isosceles right triangle, cut length(c), preserved length(p). Prepare data for the total stretch length(S) and Net weight capacity(W) in the whole system.
N = number of cuts
S = total stretch length
W = net weight capacity
cn = cut length of nth cut
pn = preserved length of nth cut
sn = stretch length of nth cut
αn = angle of nth cut

Calculation 2: Calculate the Total Stretchable Length

Use extracted geometric shape and pythagorean theorem to calculate the stretch length of each structure.

Calculation 3: Calculate the Net Weight Capacity

Use calculated stretch length to forecast the net weight capacity.
