Design Of Half Open Shoes

The color picture J-3 is a half open gallbladder shoe. The so-called half open shoe is a kind of shoe with a structure that opens the gallbladder and is surrounded by a bar.

1. finished product drawing
As shown in figure 2-3-13, this is a pair of loose tongue shoes with tongue back. The outer side of the shoe is a gallbladder structure, and the inside side is surrounded by a cover structure. This is a pair of shoes with asymmetrical structure. When designing, we should find the key position of asymmetry, and design the inside and outside arms separately.

2. structure design drawing
Half open tongue type shoe structure design is shown in figure 2-3-14. First design the tongue shoe, then design the asymmetrical structure of the front.

(L) design the original contour line to find the J'point, use the Huai shoe cover to duplicate the board, and design the Li Wai Wai line from the back curve, to the O' point. From the point of J', the width of the outer shoe is set to Jo, connecting the auxiliary line and designing the original line of the shoe gall. Pay attention to the difference between the shoe cover and the inside of the shoe.

(2) the lines that are just designed by the contour line of the Wai pattern are the Wai line and the Wai Wai line. Among them, the Li Wai line is turned to the outer side and intersects with the outer half line. The small area obtained from the front end is the amount of excess in the Li Wai enclosure, as shown in the dotted line in the picture.

(3) make a straight midline with the contour line of the shoe gallbladder. Draw the outline of the shoe cover and the outline of the outer shoe in the straight line, and get the outline of the shoes and the outer shoes. As shown in figure J1V, the area of O'Jo is shown. This is also a kind of double line pick up.
Master the design points of the shoe covers, and master the key points of the design of the opening gallbladder shoes.
Finally, the contour of the bottom rib and the difference between inside and outside are designed.

3. sample preparation
The basic template is shown in figure 2-3-15, the solid line is the basic template contour, and the dotted line is the opening pattern plus the volume. The weight of the cross arm is increased and the amount of hem is added to replace the shoe.

From the cover shoes to the gallbladder shoes, the shapes of the two are far from each other, but they all belong to the color changes of the front Gang, so the principles of the design are interlinked. The three step method mentioned in many times is to distinguish the order of design and carry out it step by step.
