Design Of Inner Ear Shoes -- Principle Of Positioning And Taking Off

    

The inner ear shoe is a popular footwear. It is suitable for people to have a wide range and simple structure. It is often the preferred sample shoe for design. The most famous men's three quarter shoes also belong to the inner ear type shoes. Because the structure is very classic, they will be specially described in the next section.

Design of inner ear shoes for men and women requires positioning and taking stilts. In the introduction, it has been pointed out that positioning and taking off refers to the process of handling stilts in the calibration of natural stilts and its vicinity. In the application of positioning and taking off, a classic example is the design of shoes for two men's shoes. Of course, two styles of shoes are not fashionable and fashionable, but they also have their own brilliance. Just because of the different times, people have a new and higher pursuit. It is precisely because of the brilliance of the two quarter shoes that it laid the foundation for the various styles of shoes later, leaving valuable experience wealth for future generations. From the angle of taking off the hands, the two section shoes of men and women are the simplest and most direct application of natural stilts. If you really master the design of the two quarter shoes for men and women, the other variant design is all done overnight.

See color A series. This is a set of inner ear shoes. The common feature of inner ear shoes is that the front parts are pressed on the shoe ears.

The color picture A-l is a traditional pair of inner ear men's two quarter shoes, but there is a protrusion on the front door of the front door as the skin of the guard, and the stitches of the front ones are made up of 4 lines, which are different from the general stitching technology. The shoe has been changed into a soft mouth wrapped with foam, which can meet the requirements of modern people for comfort.

The color picture A-2 is a women's two quarter shoe. The shoe last is a super long last. Unlike traditional habits, there are 5 eyes on the shoe ears, and the location of the door is closer. Its decoration is characterized by 3 groups of false lines for the decoration of the facet, which is lively and lively.

The color picture A-3 is a modified men's two quarter shoe, with a broken line at the shoe ear, forming the middle and back parts. The front and back sides are decorated with flower teeth and flower holes, and the front and rear positions of shoes are decorated with flower holes. The mouth door has a protective leather part, which is a popular technology in recent years to prevent opening and tear of the door. When processing, the guard skin is first combined with the rear car, then then the front and back sides.

The color picture A-4 is also a variant of the men's two quarter shoes. The front door of the front door is relatively close, and the front end of the shoe ear is not closed but separated. It looks like the outer ear type shoes. But from the structural relationship, it is still the inner ear structure of the front shoe. However, the application of the shoe wide foam, the shape of the rear package and the broken line of the back waist have increased the composition of leisure. Attention to the shoe tongue is also the use of the slit technology, with the mouth of the shoe, shoe ear decorative false line is very alternative, and the various parts of the lines echoed before and after.

The color picture A-5 is an ordinary looking inner ear shoe, but it has 7 shoe eyes, especially the front end of the shoelace with a lock line. Who is locked? If you look carefully, you will find that the shoes and ears are connected with the front gang. Only the shoe ears on the outer side are interlocked with the front ones, and the locking wires are used to reinforce the outer arms. This is an asymmetric structure shoe with special configuration.

A-6 is a conservative women's two quarter shoe. It is conservative because modern women's shoes are beautiful with "revealing and penetrating". This shoe is wrapped too tightly, but the arc curve of the shoe sole leaves a gentle touch.
 

   Positioning and taking off principle diagram

When designing the inner ear shoes with positioning and picking, first, grasp the drawing of the positioning and taking off principle diagram. The positioning and picking up schematic diagram is an abstract illustration without considering the specific style and taking only the pick up principle, which is suitable for all applications of positioning and picking. Generally, we use half panel to draw the location and take off diagram, see 1-2-1.

 

As shown in the picture, the position of the natural stilts is expressed in the form of shadow, which means that the seesaw processing should be performed at VOV. That is to say, the length of the front is AV, the length of the back is VE, and a VOV between the front and back sides is taken, so that the half panel of the plane can be converted into a curved surface.

If we move the center point 0 'point slightly, will it affect the effect of taking off? According to the principle of cross picking, if we take the change of the center, we should adjust the size of the corner to achieve the same effect. See 1-2-2.

As shown in the figure, after transferring the center from O to 07, it only needs to connect vo'V. The size of "VO'V" is not the same as that of VOV, but the same function can ensure that the length of the midline is unchanged, so that the half panel can be transformed from plane state to curved surface.

The reason is very simple, that is, when the last surface is flattened, if the vertex of the scissors point points to 0 ', it can also flatten the last surface. However, it should be noted that the 0 'point can only change near the O point. 0, the closer the point is from the O point, the better the effect will be.

The drawing angle on the schematic diagram is a single corner, and there is still a gap between the application and the application of the location. If we take the crooked corner, will it affect the effect of taking off? If the center of the pick is not changed and the size of the stilling angle does not change, it will not affect the picking effect. It is just like flattening, not cutting a straight line, but cutting it into a curved curve, which will not affect the flatten effect of the last surface. Accordingly, we can make a bending positioning and take off corner, and draw the contour line of the template, connecting the two sides of the picking angle with the front and rear parts respectively. This schematic diagram has practical value, see Figure 1-2-3.
 

As shown in the figure, the fetch angle in the drawing shows that there is a overlap angle between the two parts of the front and back parts, the front contour line should be taken in the position of the V'O'line, and the contour line should be taken at the VO line position. As a result, there is a corner between the front and the back. This angle can cause the parts to be crooked. Because this stilling angle comes from natural stilts, this ensures the upper end effect of the upper.

As part of the front part, there will be a change in the contour of the midline and the bottom of the front line besides the angle of the pick. We call the three elements of the pick up angle, the front middle line and the bottom mouth contour as the three elements of picking up the stilts. What is the size of the stilts? Where is the back line connecting to the front? How to connect the bottom port?

When positioning and taking off, the seating angle is derived from the natural stilts, and the size of the corner is taken by using the eclectic angle, and the position of the pick is located on the natural stilt position or near.

The front midline of the front is connected to the straight line through the J point, and the front point is A. To indicate, the front line of the front line is also called the Ao line.

The location of the bottom mouth contour is basically unchanged, from the A point on the half panel to the back midline, and the intersection point of the midline is Ao point.

The principle of taking off the inner ear shoe is the same as that of the two head shoes.
