Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of shoe design, in particular to a 2D and 3D multi-purpose cardboard structure. Background Art
[0002] In the initial stage of shoe design, designers usually draw the basic shape and structure of shoes on cardboard to verify the feasibility and aesthetics of the design. Once the design is confirmed, the cardboard will be used to make shoe samples, and this process is called "proofing". The cardboard shoe sample can intuitively display the style, size and comfort of the shoes, which helps producers make necessary adjustments to the design before actual production. The shoe sample cardboard is the cardboard used to make shoe samples or shoe molds, usually made of relatively hard paper or cardboard materials. The shoe sample cardboard is an important tool in the shoe design and production process, used to determine the shape, size and structure of shoes.
[0003] In the key process of shoe design, designers will first closely attach the masking paper to the shoe last, and then, taking it as a carrier, present the shoe style outline and design details one by one on the masking paper through fine tracing skills. After completing this design step, the masking paper will be carefully torn off and placed flat on the shoe sample cardboard. Then, designers will use professional tools such as compasses, rulers and hole punching rulers to precisely cut, carefully trace and perform necessary punching operations on the shoe sample cardboard to ensure that every part of the shoe sample cardboard meets the design requirements. This series of finishing steps not only improves the design accuracy of the shoe sample cardboard, but also lays a solid foundation for the subsequent splicing and finishing work. Although this process requires high professional qualities and operation skills of designers and sacrifices design efficiency to a certain extent. Content of the Utility Model
[0004] Based on this, the purpose of the utility model is to provide a 2D and 3D multi-purpose cardboard structure to solve the technical problem that the traditional shoe sample cardboard structure requires high operation skills and reduces the design efficiency.
[0005] To achieve the above purpose, the utility model provides the following technical scheme: A 2D and 3D multi-purpose cardboard structure, including a cardboard main body and a last-attached paper. A coating is provided on the top surface of the cardboard main body. The coating includes main grid lines, and multiple main grid lines divide into multiple sub-areas. Multiple sub-grid lines are arranged inside the sub-areas. A heating mechanism is arranged above the cardboard main body. Both the main grid lines and the sub-grid lines are temperature-sensitive color-changing coatings, and the main grid lines and the sub-grid lines are colorless at normal temperature.
[0006] By adopting the above technical solution, with the assistance of main grid lines and subdivision grid lines, it is helpful to improve the processing accuracy of operations such as cutting, tracing, and punching the cardboard body. These grid lines provide clear guidance and positioning for the operation, so that each step can be carried out accurately, thereby ensuring the design accuracy of the shoe sample cardboard.
[0007] Furthermore, the width of the plurality of main grid lines is greater than that of the subdivided grid lines.
[0008] By adopting the above technical solution, the main grid lines are made more eye-catching and prominent visually. Since the main grid lines are wider, they have a stronger presence on the cardboard and are easier to notice.
[0009] Furthermore, the subdivision area is in a rectangular structure with the same length and width, and the multiple subdivision grid lines divide the subdivision area into rectangular structures with the same length and width.
[0010] By adopting the above technical solution, it is ensured that each subdivision has the same shape and size, providing a unified basis for subsequent processing operations. Since the size of each subdivision is consistent, it enables faster positioning during cutting, tracing, punching and other operations, thereby improving the accuracy and efficiency of the operation.
[0011] Furthermore, the main grid lines and subdivision grid lines are in two but not limited to two colors to express similar shapes.
[0012] By adopting the above technical solution, the recognition of grid lines can be improved. Through color differentiation, operators can more clearly identify the main grid lines and subdivision grid lines, so that they can more accurately position when performing processing operations such as cutting, tracing, and punching.
[0013] Furthermore, the main grid lines and subdivision grid lines are two but not limited to two arrangement size expressions.
[0014] By adopting the above technical solution, the flexibility and adaptability of the grid line system are increased, and different arrangement sizes can be adjusted according to the specific needs and designs of the shoe sample cardboard, thereby better meeting the design requirements of different shoe styles.
[0015] Furthermore, the heating mechanism is used to increase the temperature of the area where the main grid lines and the subdivided grid lines are located. The heating mechanism has two but not limited to two forms.
[0016] By adopting the above technical solution, the heating mechanism can increase the temperature of the area where the main grid lines and subdivided grid lines are located. This is the key to achieving the color-changing effect of the grid lines. Through heating, the color of the grid lines will change, making them easier to identify and locate, which is beneficial to subsequent shoe sample cardboard processing operations.
[0017] Furthermore, a supporting desktop is provided at the bottom of the cardboard main body, and the cardboard main body is clamped and fixed to the supporting desktop through a clamping plate.
[0018] By adopting the above technical solution, the stability and reliability of the cardboard main body during the processing are ensured. The supporting desktop provides a flat working platform for the cardboard, while the clamping plate effectively fixes the cardboard to prevent it from moving or deforming during the operation.
[0019] In summary, the present utility model mainly has the following beneficial effects:
[0020] 1. Through the coating, with the assistance of the main grid lines and the subdivision grid lines, the present utility model is indeed beneficial to improving the processing precision of operations such as cutting, tracing, and punching of the cardboard main body. These grid lines serve as references, enabling the operator to position more accurately during various processing operations, thereby ensuring that all parts of the shoe pattern cardboard can be precisely processed according to the design requirements. At the same time, this improvement in precision also directly promotes the improvement of the design precision of the shoe pattern cardboard. Because the guarantee of processing precision is the premise for the realization of design precision, only when the errors are minimized during the processing can the designer's intentions and details be completely and accurately presented on the final shoe pattern cardboard. Therefore, the existence of the main grid lines and the subdivision grid lines not only facilitates the processing but also has a positive impact on the design quality of the shoe pattern cardboard;
[0021] 2. By setting up a heating mechanism, the main grid lines and the subdivision grid lines adopt temperature-sensitive color-changing coatings. After the heating mechanism is turned off, as the outside temperature gradually drops to the normal temperature state, these lines will gradually change from colored to colorless, so that after the processing of the shoe pattern cardboard is completed, the grid lines will not leave obvious traces, thus avoiding the influence of the lines on the production of the finished shoe pattern cardboard. At the same time, the temperature-sensitive color-changing characteristic also improves the convenience of use. The operator does not need additional steps or tools to remove the grid lines, and only needs to control the temperature to achieve the appearance and disappearance of the lines, simplifying the operation process and improving the work efficiency.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.
[0028] Next, the embodiments of the present utility model will be described according to its overall structure.
[0029] Embodiment 1:
[0030] A 2D and 3D multi - purpose cardboard structure, as Figures 1-4 shown, includes a cardboard main body 1 and a last - fitting paper 3. A coating 2 is coated on the top surface of the cardboard main body 1. The coating 2 includes main grid lines 201. The multiple main grid lines 201 divide into multiple fine partition areas 202. Multiple sub - division grid lines 203 are arranged inside the fine partition areas 202. A heating mechanism 4 is arranged above the cardboard main body 1. Both the main grid lines 201 and the sub - division grid lines 203 are temperature - sensitive color - changing coatings. The main grid lines 201 and the sub - division grid lines 203 are colorless at normal temperature. With the assistance of the main grid lines 201 and the sub - division grid lines 203, it is beneficial to improve the processing accuracy of operations such as cutting, tracing, and punching of the cardboard main body 1. These grid lines provide clear guidance and positioning for operations, enabling each step of the operation to be carried out accurately, thus ensuring the design accuracy of the shoe - pattern cardboard. At the same time, such grid lines improve the processing and design efficiency of the shoe - pattern cardboard. Since there are clear lines as references, operators can complete the work more quickly when performing steps such as cutting, tracing, and punching, reducing unnecessary adjustments and corrections, thereby saving time and costs.
[0031] Refer to Figure 2 , Figure 4 , the width dimension of the multiple main grid lines 201 is greater than that of the sub - division grid lines 203, making the main grid lines 201 more eye - catching and prominent visually. Since the main grid lines 201 are wider, their presence on the cardboard is stronger and they are easier to notice. At the same time, the wider main grid lines 201 also provide a larger tolerance space for operations. When performing operations such as cutting and tracing, even if slightly deviated from the center of the main grid lines 201, accurate positioning can still be achieved relying on their wider lines, thus ensuring the accuracy of the operation and the design accuracy of the shoe - pattern cardboard. It not only improves the convenience of the operation but also effectively prevents waste of cardboard caused by operation errors.
[0032] Refer to Figure 2、 Figure 4 The subdivision area 202 has a rectangular structure with consistent length and width. Multiple subdivision grid lines 203 divide the subdivision area 202 into rectangular structures with consistent length and width, ensuring that each subdivision area 202 has the same shape and size, providing a unified basis for subsequent processing operations. Since the size of each subdivision area 202 is consistent, it enables faster positioning during operations such as cutting, tracing, and punching, thereby improving the accuracy and efficiency of the operation. At the same time, multiple subdivision grid lines 203 divide the subdivision area 202 into rectangular structures with consistent length and width. This regular layout helps to simplify the processing process. Operators can perform orderly operations based on these small rectangular blocks, avoiding confusion and errors.
[0033] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The main grid lines 201 and the subdivision grid lines 203 are of two, but not limited to, colors that are similar in appearance, which helps to improve the recognition of the grid lines. Through the color distinction, the operator can more clearly identify the main grid lines 201 and the subdivision grid lines 203, so that they can be positioned more accurately during processing operations such as cutting, tracing, and punching. At the same time, the diversity of colors also increases the visual layering of the shoe sample cardboard, making the entire cardboard structure more beautiful and attractive, which not only improves the practicality of the shoe sample cardboard, but also adds more aesthetic value to it.
[0034] See also Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 The main grid lines 201 and the subdivision grid lines 203 are two, but not limited to, arrangement size expressions, which increases the flexibility and adaptability of the grid line system. Different arrangement sizes can be adjusted according to the specific needs and designs of the shoe pattern cardboard, thereby better meeting the design requirements of different shoe styles. At the same time, multiple arrangement size expressions also help to improve the processing accuracy and efficiency of the shoe pattern cardboard. Operators can select the appropriate grid line size for cutting, tracing, punching, and other operations according to actual conditions to obtain more accurate positioning and more refined processing effects.
[0035] Embodiment 2:
[0036] See also Figure 1, the heating mechanism 4 is used to raise the temperature of the area where the main grid lines 201 and the sub-grid lines 203 are located. The heating mechanism 4 has two but not limited to two forms of manifestation. The heating mechanism 4 can raise the temperature of the area where the main grid lines 201 and the sub-grid lines 203 are located. This is the key to achieving the color-changing effect of the grid lines. Through heating, the color of the grid lines will change, making them easier to identify and locate, which is beneficial to subsequent shoe pattern cardboard processing operations. At the same time, the two or more forms of manifestation of the heating mechanism 4 provide more selectivity and flexibility. Different heating methods can be selected according to specific requirements and conditions. For example, heating lamps are suitable for small-area local heating, while hot air guns are suitable for large-area rapid heating. This diversity helps to meet the heating needs in different scenarios and improve the processing efficiency and quality of shoe pattern cardboard.
[0037] Refer to Figure 1 、 Figure 3 , a support table 6 is provided at the bottom of the cardboard body 1. The cardboard body 1 is clamped and fixed to the support table 6 through a clamping plate 5, ensuring the stability and reliability of the cardboard body 1 during the processing. The support table 6 provides a flat working platform for the cardboard, while the clamping plate 5 effectively fixes the cardboard to prevent it from moving or deforming during the operation. At the same time, the stable support and fixation also improve the processing accuracy of the shoe pattern cardboard. During operations such as cutting, tracing, and punching, the cardboard will not shake or shift, thus ensuring the accuracy and consistency of the operation. This not only improves the quality of the shoe pattern cardboard but also increases the production efficiency.
[0038] The implementation principle of the present utility model is as follows: First, use the clamping plate 5 to clamp the cardboard body 1 on the top of the support table 6. Subsequently, turn on the heating mechanism 4. The heating mechanism 4 can be in the structural form of a heating lamp, a hot air gun, etc., and perform heating treatment on the main grid lines 201 and the sub-grid lines 203, causing the colors of the main grid lines 201 and the sub-grid lines 203 to gradually become prominent. Then, place the designed last-fitting paper 3 on the top of the cardboard body 1, and according to the designed shape of the last-fitting paper 3, use tools to perform processing operations such as cutting, tracing, and punching on the cardboard body 1 to obtain the finished product of the shoe pattern cardboard. During the processing, with the assistance of the main grid lines 201 and the sub-grid lines 203, it is beneficial to improve the processing accuracy of operations such as cutting, tracing, and punching on the cardboard body 1, enhance the design accuracy of the shoe pattern cardboard, have an effective auxiliary effect on the processing operations, and improve the processing and design efficiency of the shoe pattern cardboard. When using the shoe pattern cardboard for splicing or use, turn off the heating mechanism 4, causing the temperature outside the main grid lines 201 and the sub-grid lines 203 to gradually drop to the normal temperature state, which is beneficial to changing the main grid lines 201 and the sub-grid lines 203 from colored to colorless states, avoiding the influence of the lines of the main grid lines 201 and the sub-grid lines 203 on the production of the finished shoe pattern cardboard, and enhancing the usability.
[0039] Parts not involved in the present utility model are the same as or can be implemented using the prior art, and will not be elaborated here.
[0040] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and not limitations thereof.
