Description

Technical Field

[0001] The present invention relates to the technical field of teaching models, and in particular to a multifunctional and variable fold position classification teaching model. Background Art

[0002] Folds are a core research topic in geology and structural geology. Understanding their configurational classification and transitional relationships is crucial for students to grasp the laws governing crustal movement and tectonic evolution. In traditional geology instruction, the classification of fold configurations is typically demonstrated through textbook illustrations, static models, or field surveys. However, these methods have significant limitations. First, textbook illustrations and static models can only present fixed fold configurations and are unable to dynamically demonstrate the transitional relationships between the seven fold configurations (e.g., upright horizontal folds, upright inclined folds, inclined vertical folds, oblique horizontal folds, recumbent folds, recumbent folds, and oblique inclined inclined folds). This makes it difficult for students to intuitively understand the evolution of fold morphology.

[0003] Secondly, traditional teaching often uses a set of seven independent models to demonstrate different folds. This approach not only increases the burden on teachers during classroom preparation and transportation, but also requires a large number of models and takes up a lot of space, making it inconvenient for daily teaching. Furthermore, static models lack interactivity, and students can only passively observe during the learning process, unable to deeply understand the deformation mechanism of folds through manipulation. While field trips can provide real-life examples of folds, they are limited by time, location, safety factors, and weather conditions, making them difficult to use as a regular means of daily teaching. Furthermore, it is difficult for students to systematically observe the complete transition process of all seven fold folds during field trips.

[0004] These deficiencies in existing technologies lead to low teaching efficiency, low learning enthusiasm, insufficient students' understanding of fold position classification, and unsatisfactory learning results. Therefore, it is particularly necessary to develop a multifunctional and variable fold position classification teaching model. Summary of the Invention

[0005] The purpose of the present invention is to provide a multifunctional and variable fold position classification teaching model to solve the problems raised by the above background technology.

[0012] As a preferred technical solution of the present invention, the deformable rod with a suction cup is of detachable design, and the rod can be deformed 90° in all directions. The rectangular block-shaped soft simulation object is connected to the transparent plastic shell through the deformable rod with a suction cup and simulates different wrinkle shapes.

[0013] As a preferred technical solution of the present invention, the teaching model is suitable for teaching geology and structural geology, and helps students intuitively understand the classification of fold positions and the transition relationship between the seven types of folds through dynamic demonstration.

[0014] As a preferred technical solution of the present invention, the method for making the rectangular block-shaped soft simulated object includes the following steps:

[0015] a. Prepare flexible silicone raw materials by mixing silicone base material, silicone oil softener and curing agent in a mass ratio of 100:15:5, where the silicone oil softener is used to enhance the softness of the silicone;

[0016] b. Divide the prepared silica gel raw material into three parts, add red, yellow and blue food-grade pigments, each adding 0.5% of the mass of the silica gel raw material, stir evenly to form a silica gel mixture of three different colors;

[0017] c. Prepare a rectangular mold, apply mold release agent to the inner wall of the mold, pour the first color silicone mixture into the bottom of the mold to form the first layer with a thickness of 5 mm, and pre-cure at 45°C for 30 minutes;

[0018] d. After the first layer is pre-cured, pour the second color silicone mixture to form a second layer with a thickness of 5 mm. Pre-cure it at 45°C for 30 minutes.

[0019] e. Repeat step d and pour the third color of silicone mixture to form a third layer with a thickness of 5 mm;

[0020] f. Place the mold in a 50°C oven for overall curing for 3 hours to ensure that each layer of silicone is tightly bonded while maintaining its softness;

[0021] g. After curing is completed, the mold is cooled to room temperature and demolded to obtain a rectangular block-shaped soft simulant with a layered structure.

[0022] As a preferred technical solution of the present invention, the manufacturing method further includes the steps of manufacturing and installing the deformable rod with a suction cup:

[0023] In the mold design, two circular mounting holes with a diameter of 10 mm and a depth of 5 mm are reserved at the bottom and side of the rectangular block-shaped soft simulant;

[0024] After curing and demoulding, insert the deformable rod with silicone suction cup into the reserved mounting hole and use silicone special adhesive for bonding. The amount of adhesive applied is 0.2 grams for each mounting hole.

[0028] The silicone base material uses low-hardness silicone with a Shore A hardness value of 10;

[0029] During the stirring process, the silicone mixture needs to be stirred in a vacuum environment for 10 minutes to remove bubbles and avoid affecting the softness and deformation ability after curing;

[0030] The temperature of pre-curing and overall curing is controlled between 45°C and 50°C to avoid hardening of the silicone due to high temperature, so that the simulant has good flexibility and resilience when deformed.

[0031] Compared with the prior art, the present invention has the following beneficial effects:

[0032] The present invention's multifunctional and adaptable fold-state classification teaching model offers significant advantages in teaching effectiveness. By holding a transparent plastic shell and changing its position, the rectangular, block-shaped soft simulant dynamically deforms, visually demonstrating seven fold states and their transitional relationships. Students can clearly observe the relative displacement and morphological changes of different colored strata during deformation, thereby gaining a deeper understanding of fold state classification and evolution. Compared to traditional static models or illustrations, the model's dynamic demonstration significantly enhances the intuitiveness and interactivity of teaching, helping students more quickly and comprehensively grasp fold-related knowledge in geology and structural geology.

[0033] The model also excels in practicality. While traditional teaching requires a set of seven separate models, the present invention demonstrates all wrinkle positions through a single model design. The detachable structure of the deformable rod with suction cups not only reduces the burden on teachers for handling and classroom preparation, but also facilitates storage and transportation. The model has a simple structure and a mature manufacturing process. The rectangular block-shaped soft simulant is made of flexible silicone material, which is flexible and durable, making it suitable for long-term teaching use. Overall, this teaching model, with its intuitive, efficient, portable and practical features, provides an innovative tool for geology teaching and has high application value and promotion prospects.

[0039] To further illustrate the multifunctional and variable wrinkle position classification teaching model of the present invention, the following describes in detail a specific implementation method. These embodiments are intended solely to illustrate the technical solution of the present invention and do not limit its scope. Equivalent substitutions or improvements made by persons skilled in the art without departing from the technical solution of the present invention are also within the scope of protection of the present invention.

[0040] This invention provides a multifunctional and adaptable fold position classification teaching model suitable for teaching geology and structural geology. The following describes the structure, production method, and usage of this model in detail, along with specific implementations. First, the main structure of the model includes a transparent plastic shell with scales 1, a rectangular block-shaped soft simulated object 2, and a deformable rod 3 with a suction cup.

[0041] The transparent plastic shell 1 is a cubic or rectangular parallelepiped structure, closed on all sides and open at the top. Its dimensions can be designed according to teaching needs, for example, 30 cm x 20 cm x 15 cm in length, width, and height, ensuring that the internal structure is clearly visible and facilitating students' observation of changes in wrinkle morphology. A rectangular, block-shaped soft simulant 2 is placed within the transparent plastic shell 1. Made of plastic material, it simulates geological rock formations and has dimensions slightly smaller than the shell's internal space, for example, 28 cm x 18 cm x 10 cm, to ensure sufficient space during deformation. An insertable deformable rod 3 with a suction cup is located at the bottom and side of the rectangular, block-shaped soft simulant 2. The rod is longer than the rectangular, block-shaped soft simulant. The deformable rod 3 with the suction cup deforms under force, exhibiting different wrinkle configurations. Each deformable rod with a suction cup has a diameter of 10 mm. The deformable rod 3 with a suction cup is fixed to the bottom of the inner wall of the transparent plastic shell 1 through adsorption, ensuring that the position of the simulation object in the shell is stable. At the same time, the deformable rod 3 with a suction cup is designed as a detachable structure, which is convenient for disassembly, storage and transportation. For example, the simulation object can be taken out after the teaching is completed to reduce storage space.

[0042] The rectangular block-shaped soft simulant 2 utilizes a layered design to simulate the stratified characteristics of different geological rock layers. Each layer has a different color, facilitating observation of the relative displacement and deformation of each layer during folding. The specific production method is as follows: First, a flexible silicone raw material is prepared by mixing a silicone base material, a silicone oil softener, and a curing agent in a mass ratio of 100:15:5. The silicone base material is a low-hardness silicone with a Shore A hardness of 10 to ensure the simulant's softness. The silicone oil softener enhances the silicone's flexibility, and the curing agent ensures the silicone's molding stability. The prepared silicone raw material is divided into three parts, and three food-grade pigments (red, yellow, and blue) are added to each part. The pigment is added at a rate of 0.5% of the silicone raw material's mass, or 0.5 grams per 100 grams of silicone raw material. The mixture is then stirred under vacuum for 10 minutes to remove bubbles and prevent any impact on its softness and deformability after curing. This results in a silicone mixture of three different colors. Next, a rectangular mold was prepared and the inner surface coated with release agent to facilitate subsequent demolding. The first color of silicone mixture was poured into the bottom of the mold to form the first layer, with a thickness of 5 mm. The mixture was pre-cured at 45°C for 30 minutes to allow the surface to cure initially but still remain tacky enough for the next layer to bond. After the first layer was pre-cured, the second color of silicone mixture was poured in to form the second layer, also 5 mm thick. This was pre-cured at 45°C for another 30 minutes. The third color of silicone mixture was then poured in to form the third layer, with a thickness of 5 mm. The total thickness of the three silicone layers in the mold was now 15 mm. The mold was then placed in a 50°C oven for curing for 3 hours, ensuring that the silicone layers bonded tightly while maintaining flexibility and good resilience. After curing, the mold was cooled to room temperature and demolded to produce a rectangular block of soft simulant 2 with a layered structure. The mold design included four circular mounting holes with a diameter of 10 mm and a depth of 5 mm at the bottom of the simulant.

[0043] After demoulding, the deformable rod 3 with a silicone suction cup is inserted into the reserved mounting hole and bonded with a special silicone adhesive, with 0.2 grams of adhesive applied to each hole. After bonding, the simulant is placed at room temperature for 24 hours to ensure that the deformable rod 3 with the suction cup is firmly bonded to the bottom of the simulant without affecting the overall softness. The deformable rod (3) with the suction cup includes a rubber column and a suction cup, and the rubber column is fixedly connected to the suction cup.

[0044] During use, the teacher puts his hand into the transparent plastic shell 1 and manually changes the state of the hinge and axial plane of the deformable rectangular block-shaped soft simulation object 2, causing the deformable rod to deform, thereby dynamically displaying seven fold positions and their transition relationships. The seven fold positions include: upright horizontal folds, the axial plane of the upright horizontal folds is >80°, the hinge inclination angle is <10°, upright inclination folds, the axial plane of the upright inclination folds is >80°, the hinge inclination angle is 10-80°, inclined vertical folds, the axial plane of the inclined vertical folds is >80°, the hinge inclination angle is >80°, skewed horizontal folds, the axial plane of the skewed horizontal folds is 10-80°, the hinge inclination angle is <10°, horizontal folds, the axial plane of the horizontal folds is <10, the hinge inclination angle is <10°, and oblique folds, oblique folds The axial plane and hinge dip angles are 10-80°, the hinge dip angle is >80° on the axial plane side, and the oblique and tilted folds are tilted and tilted. The axial plane and hinge dip angles of the oblique and tilted folds are 10-80°. When the shell is kept horizontal, the simulator presents a horizontal fold state; by gradually tilting the shell to 80°, the simulator deforms into an upright fold; continuing to adjust the angle to 50°, an inclined fold is formed; further tilting to 10° forms a recumbent fold; by flipping or rotating the shell up and down, anticline folds, syncline folds, and compound folds can be formed respectively. Because the simulator adopts a layered design, students can clearly observe the relative displacement and morphological changes of each rock layer during the deformation process through different color layers, thereby intuitively understanding the classification of fold positions and the transition relationship between the seven types of folds. This model is suitable for teaching geology and structural geology. It can help students deeply grasp the knowledge related to folds through dynamic demonstrations, significantly improving teaching effectiveness.
