Description

Technical Field

[0001] The present invention relates to the field of mechanical memory technology, and in particular to a mechanical memory unit, a unit cell, a device and a method of use. Background Art

[0002] Currently, mechanical memory units mainly include two types: bistable and multistable structures. The bistable structure is more common in the field of mechanical memory units. It has two stable states, just like a simple switch, with two states of "on" and "off", corresponding to "0" and "1" in binary system respectively. This structure stores and reads information by switching between these two stable states. The technology is mature and widely used. The multistable structure demonstrates powerful information storage capabilities. It has three or more stable states, each of which can correspond to different data encodings, allowing it to store more information. However, the implementation of the multistable structure is more complex, requiring not only a higher level of technology in design and manufacturing, but also greater challenges in controlling state switching, requiring more precise control mechanisms and more complex algorithms.

[0003] Under current technological conditions, there is no mechanical memory unit that can flexibly switch between monostable and bistable states. This technological gap limits the application of mechanical memory units in more complex scenarios and also provides broad space for future research and development. Summary of the Invention

It should be noted that the concepts of "first", "second", etc. mentioned in the present invention are only used to distinguish different devices, modules or units, and are not used to limit the order or interdependence of the functions performed by these devices, modules or units.

[0041] It should be noted that the modifications of "one" and "multiple" mentioned in the present invention are illustrative rather than restrictive. Those skilled in the art should understand that unless otherwise clearly indicated in the context, it should be understood as "one or more".

[0042] like Figure 1-6 As shown, an embodiment of the present invention provides a mechanical memory unit, including a first frame 11, a second frame 12, a first arch plate 2 and a second arch plate 3; the first frame 11 and the second frame 12 are detachably connected to form an annular frame; one end of the first arch plate 2 and the second arch plate 3 are both arranged on the first frame 11, and the other end are both arranged on the second frame 12, and the arched concave surfaces of the first arch plate 2 and the second arch plate 3 are arranged opposite to each other; when the first frame 11 and the second frame 12 are not connected, the second arch plate 3 is automatically restored by releasing its own elastic potential energy after reverse convex deformation; when the first frame 11 and the second frame 12 are connected, the second arch plate 3 is reverse convex deformed and maintains the deformed configuration.

[0043] In this embodiment, the mechanical memory unit is primarily composed of a first frame 11, a second frame 12, a first arched plate 2, and a second arched plate 3. These components work together to achieve the unique function of mechanical memory. The first frame 11 and the second frame 12 are detachably connected. This design allows for flexible adjustment of their relative position, providing the structural foundation for the mechanical memory unit to achieve different stable state characteristics. One end of the first arched plate 2 and the second arched plate 3 are both attached to the first frame 11, and the other end to the second frame 12. Their arched concave surfaces face each other, forming a unique double-arched structure. The first arched plate 2, with its rigidity and stability, provides the necessary support and restraint for the entire frame, ensuring the overall structural strength of the mechanical memory unit. The second arched plate 3, acting as a deformable member, is a key component in achieving the mechanical memory unit's function. This mechanical memory unit has a sophisticated structural design and unique functionality, enabling flexible switching between monostable and bistable modes. The structural characteristics and principles of the two modes are detailed below.

[0044] (1) Monostable structural characteristics: When the first frame 11 and the second frame 12 are disconnected, the second arched plate 3 can automatically recover by releasing its own elastic potential energy after the reverse convex deformation. At this time, the mechanical memory unit exhibits a monostable structure. The monostable structure means that the second arched plate 3 always operates around a stable state. No matter what external force causes the reverse convex deformation, it will automatically return to its initial state as soon as the external force disappears.

[0045] Monostable principle: Figure 1 As shown, when the first frame 11 and the second frame 12 are not connected, the two are spaced apart to form a frame, and the frame is supported and constrained by the first arched plate 2. Since the first arched plate 2 has a certain elastic deformation ability, the overall frame has less constraint on the reverse convex deformation of the second arched plate 3. During the process of the second arched plate 3 being subjected to force and reverse convex deformation, since the first frame 11 and the second frame 12 are not connected to each other, the spacing between them will change with the deformation of the second arched plate 3. Specifically, the two ends of the second arched plate 3 will first open and then gradually recover, and the spacing between the corresponding first frame 11 and the second frame 12 will first increase and then decrease. When the external force disappears, the elastic potential energy stored in the second arched plate 3 due to the reverse convex deformation is released. This elastic potential energy is sufficient to overcome the elastic restraining force generated by the first arched plate 2 on the first frame 11 and the second frame 12, thereby driving the second arched plate 3 to return to its initial state, so that the entire mechanical memory unit returns to its only stable state, i.e., the initial state, forming a monostable structure. The mechanical memory unit under the monostable structure is similar to a "spring" with self-recovery ability, that is, when the first frame 11 and the second frame 12 are not connected, they cannot prevent the second arch plate 3 from recovering after the reverse convex deformation. Therefore, the second arch plate 3 can always maintain its initial state.

[0046] Monostable deformation process: such as Figure 6 As shown, a load is applied to the top of the second arched plate 3, pressing it downward to the bottom. During this process, the top of the second arched plate 3 moves approximately vertically downward and deforms symmetrically at both ends about the vertical centerline. The first arched plate 2 is compressed and deformed to a certain extent, and the distance between the two ends first increases and then decreases. After the load is removed, the second arched plate 3 rebounds. During this rebound, the first arched plate 2 is deformed to a certain extent, and the distance between the two ends first increases and then decreases until it returns to its initial state.

[0047] (2) Bistable structural characteristics: When the first frame 11 and the second frame 12 are connected, the second arched plate 3 maintains the deformed configuration after the reverse convex deformation. At this time, the mechanical memory unit exhibits a bistable structure. The bistable structure means that after the second arched plate 3 is deformed in the reverse convex direction by an external force, it will remain in this new deformed state even if the external force disappears. Together with the initial state, it forms two stable equilibrium states, like a "seesaw" that can switch between two stable positions.

[0048] Bistable principle: Figure 2 As shown, when the first frame 11 and the second frame 12 are connected, that is, the spacing between the first frame 11 and the second frame 12 cannot be increased, so that the frame formed by the two has a greater constraint on the reverse convex deformation of the second arched plate 3. After the second arched plate 3 is subjected to a force and deformed in the reverse convex direction, due to the connection between the first frame 11 and the second frame 12, the spacing between the first frame 11 and the second frame 12 will not first increase and then decrease as when they are not connected, but will remain almost unchanged. Therefore, when the external force disappears, the elastic potential energy formed by the reverse convexity of the second arched plate 3 cannot overcome the strong limiting force generated by the connection between the first frame 11 and the second frame 12, and therefore cannot return to the initial state, and can only remain in this new deformed state, so that the entire mechanical memory unit has two stable equilibrium states, forming a bistable structure.

[0049] Bistable deformation process: Figure 7 As shown, a load is applied to the top of the second arched plate 3, pressing it downward to the bottom. During this process, the top of the second arched plate 3 moves approximately vertically downward and deforms asymmetrically at both ends about the vertical centerline. The first arched plate 2 does not deform due to the connection between the first frame 11 and the second frame 12. After the load is removed, the second arched plate 3 maintains the reverse convex deformation state, forming a second stable state.

[0050] It should be noted that the convex-concave change of the arched plate is a common memory implementation method that can realize mechanical memory, which is similar to the binary state "0" or "1". By controlling the boundary constraints, the arched plate can be made to maintain the deformed configuration after deformation, or restore the original configuration after the load is removed. In the present application, the reverse convex deformation of the arched plate is defined as: the arched plate undergoes deformation in the opposite direction to the initial arch under the action of an external load. Taking the second arched plate 3 as an example, if the second arched plate 3 is initially an arched plate with the convex surface facing upward, under the action of a specific load, it will undergo reverse convex deformation, deforming into a convex surface facing downward (i.e., concave). This deformation process is referred to as reverse convex deformation. In addition, when the second arched plate 3 is in the reverse convex deformation and maintains the deformed configuration, elastic potential energy is stored. After the first frame 11 and the second frame 12 are disconnected, the second arched plate 3 is automatically restored by releasing the elastic potential energy.

[0051] In summary, the mechanical memory unit provided by the embodiments of the present invention achieves flexible switching between monostable and bistable modes by cleverly designing the connection between the first frame 11 and the second frame 12 and utilizing the deformation characteristics of the second arched plate 3 under different constraints. This unique structural design not only enriches the functionality of the mechanical memory unit but also opens up the possibility of its application in a wider range of fields.

[0052] Alternatively, as Figure 3 and Figure 4 As shown, the first frame 11 and the second frame 12 are both U-shaped, and the U-shaped openings of the two are arranged opposite to each other; a first hook 13 is provided at both ends of the first frame 11, and a second hook 14 is provided at both ends of the second frame 12. The first hook 13 is used to hook with the second hook 14 one by one to realize a detachable connection between the first frame 11 and the second frame 12.

[0053] In this optional embodiment, the first frame 11 and the second frame 12 are both designed with a U-shaped structure, and the U-shaped openings are arranged relative to each other to form a mirror-symmetrical frame structure. A first hook 13 is provided at each end of the first frame 11, and a second hook 14 is provided at each end of the second frame 12. The first hook 13 and the second hook 14 are mechanically engaged to achieve a detachable connection between the first frame 11 and the second frame 12. The hook engagement and opening operations are easy. When engaging, the first frame 11 and the second frame 12 are squeezed relative to each other and then pressed to engage the first hook 13 and the second hook 14. When opening, the first frame 11 and the second frame 12 are squeezed relative to each other. The first hook 13 and the second hook 14 are released and automatically return to their initial state of separation. It is convenient and quick to use.

[0054] Specifically, a double U-shaped frame assembly is employed, with hook components forming an openable and retractable constraint framework. When the hooks are closed, the two frames form a closed rectangular frame structure, providing stable geometric constraints for the second arched plate 3. When the hooks are released, the frame spacing can be adaptively adjusted within the elastic deformation range of the first arched plate 2. In the bistable operating mode, the closed hooks provide sufficient barrier energy for the second arched plate 3 to maintain its deformed configuration. In the monostable operating mode, the released hooks allow the frame spacing to undergo controllable elastic displacement as the second arched plate 3 deforms in reverse.

[0055] It should be noted that, although the above-mentioned hook engagement can only limit the distance between the first frame 11 and the second frame 12 from becoming larger, it is sufficient to meet the deformation requirements of the reverse convex process of the second arched plate 3. In addition, it is only an example of an implementation method of the detachable connection between the two, and does not constitute a limitation of the present invention. In actual applications, detachable connection methods such as a snap-on structure and a latch structure can also be adopted. For example, a card boss is provided at the end of one frame, and a card slot is designed at a corresponding position of the other frame. When the two frames are close to each other, the card boss will be snapped into the card slot to form a stable connection. For another example, the end portions of the two frames overlap, and pin holes are provided at the overlapping portions. When the latch is inserted into the pin hole, the two frames form a stable connection.

[0056] Optionally, when the hook is not engaged, the first arched plate 2 undergoes elastic deformation during the reverse convex deformation of the second arched plate 3 .

[0057] The first frame 11 and the second frame 12 are generally spaced apart and arranged opposite each other, and are connected to the ends of the first arched plate 2 and the second arched plate 3, respectively. In this optional embodiment, when the first frame 11 and the second frame 12 are not connected, and an external load acts on the second arched plate 3 to cause it to convexly deform in the opposite direction, the first arched plate 2 always elastically deforms, acting as an elastic support and limiting element for the first frame 11 and the second frame 12.

[0058] Furthermore, the first and second arched panels 2 and 3 are disposed on the first and second frames 11 and 12, exhibiting no initial deformation or stress, and can be designed with equal spacing between their ends. Furthermore, the bending stiffness and critical buckling load of the arched panels can be controlled by designing parameters such as material, thickness, and span to meet varying deformation requirements.

[0059] Optionally, the second arched plate 3 is made of TPU material, and the first frame 11 , the second frame 12 and the first arched plate 2 are made of PETG material.

[0060] In this optional embodiment, TPU (Thermoplastic Polyurethane), a thermoplastic polyurethane elastomer, has many excellent properties, such as excellent elasticity, which enables the second arch plate 3 to quickly return to its original shape after being deformed by force; good wear resistance, which can extend the service life of the component; high mechanical strength, and the ability to withstand large external forces without damage. These properties make TPU very suitable as the material for the second arch plate 3, ensuring that it can work stably and reliably as a deformable part. PETG is a non-crystalline copolyester with good impact resistance and can effectively resist external impacts; it is also easy to process and can be processed by various processing methods such as injection molding, extrusion, blow molding, and 3D printing. These properties make PETG an ideal material for the first frame 11, the second frame 12 and the first arch plate 2, which not only ensures the stability of the structure, but also is easy to produce and manufacture. The full English name of PETG is: Poly(ethylene terephthalate-co-1,4-cyclohexylenedimethyleneterephthalate).

[0061] Alternatively, as Figure 5 As shown, the second arched plate 3 has a double-layer structure, including a first plate body 301 and a second plate body 302 that are spaced apart. The arches of the first plate body 301 and the second plate body 302 are connected to form a block structure 303 .

[0062] In this optional embodiment, the second arched plate 3 is composed of a first plate 301, a second plate 302, and a block structure 303, which can be an integrally formed structure. The first plate 301 and the second plate 302 are arranged in parallel and spaced apart, and the two plates are connected in the arch region to form the block structure 303, thereby forming a double-layer hollow structure. This design ensures structural strength during repeated reverse convex deformation while maintaining the critical load of the second arched plate 3 at a moderate and controllable level. Among them, another function of the block structure 303 is to provide sufficient structural thickness to adapt to the connection requirements for the subsequent mechanical memory unit cell to open a connection groove 31 in the arch of the second arched plate 3.

[0063] Alternatively, as Figure 1 and Figure 2 As shown, the first frame 11 and the second frame 12 are symmetrically arranged, and the axes of the first arch plate 2 and the second arch plate 3 are parallel and are both located on the symmetrical planes of the first frame 11 and the second frame 12 .

[0064] In this optional embodiment, the first frame 11 and the second frame 12 are symmetrically arranged, and the axes of the first arched plate 2 and the second arched plate 3 are parallel and both are located on the symmetry plane of the first frame 11 and the second frame 12, so that the overall structure has a more stable symmetrical configuration. When an external force is applied to the arch of the second arched plate 3, the force transmission path is symmetrically distributed, which can avoid unbalanced loading and stress concentration. In addition, the axes of the first arched plate 2 and the second arched plate 3 are both straight lines, parallel to the plane where the first frame 11 and the second frame 12 are located.

[0065] Alternatively, as Figure 3 As shown, the first frame 11 , the second frame 12 and the first arch plate 2 are an integrated structure; slots 15 are provided on the inner side surfaces of the first frame 11 and the second frame 12 , and both ends of the second arch plate 3 are respectively provided in the slots 15 .

[0066] In this optional embodiment, by designing the first frame 11, the second frame 12 and the first arch plate 2 as an integrated structure, a frame is formed to limit the deformation of the second arch plate 3, which significantly improves the overall structural rigidity and deformation resistance, and eliminates the risk of stress concentration that may be caused by the split connection.

[0067] In addition, the two ends of the second arched plate 3 are connected by embedding slots 15, and slots 15 are arranged on the inner side of the first frame 11 and the second frame 12. When the second arched plate 3 adopts the above-mentioned double-layer hollow structure consisting of the first plate body 301, the second plate body 302 and the block structure 303, the corresponding structure of slots 15 is composed of the first groove 151 and the second groove 152, and the first groove 151 and the second groove 152 are arranged in parallel and spaced apart. The first groove 151 also runs through the top surface of the first frame 11 or the second frame 12 to form a notch groove. The corresponding ends of the first arched plate 2 and the second arched plate 3 are respectively located on the upper and lower sides of the inner side of the first frame 11 or the second frame 12. During specific processing, a single-material 3D printer can be used to prepare the first frame 11, the second frame 12 and the first arched plate 2 as an integrated structure, as well as the second arched plate 3, and then prepared by assembling.

[0068] It should be noted that, in addition to the above-mentioned split design method, the first frame 11, the second frame 12, the first arched plate 2 and the second arched plate 3 can also be printed in one piece using a dual-material 3D printer.

[0069] Alternatively, as Figure 8-10 As shown, two first arched plates 2 and two second arched plates 3 are respectively arranged at intervals, and the arched concave surfaces of the first arched plates 2 and the second arched plates 3 are arranged opposite to each other.

[0070] In this optional embodiment, two first arch plates 2 and two second arch plates 3 are respectively arranged at intervals, and the arched concave surfaces of the first arch plates 2 and the second arch plates 3 are arranged one by one opposite to each other, forming a symmetrical double-arch coupling structure, which significantly enhances the anti-eccentric load capability of the mechanical memory unit and is suitable for complex load environments.

[0071] Optionally, the second arched plate 3 is a cosine beam structure with a cosine curve cross section.

[0072] In this embodiment, the second arched plate 3 utilizes a cosine beam structure, a common feature in bistable structures. Its cosine-curved profile creates a double-well potential energy curve during deformation, enabling precise control of the critical load and energy barrier for bistable switching. By optimizing the amplitude and wavelength of the cosine curve, the reverse bulge deformation threshold can be customized to meet the needs of different scenarios.

[0073] In addition, the first arch plate 2 can also be a cosine beam structure with a cosine curve cross-section. In order to facilitate the installation of the arch plate, a flat surface is provided on the outer side surface of the arch top of the first arch plate 2 and the second arch plate 3, and a flat plate structure is provided at both ends of the arch.

[0074] Optionally, the arched concave surfaces of the first arched plate 2 and the second arched plate 3 are symmetrically arranged.

[0075] In this optional embodiment, the arched concave surfaces of the first arched plate 2 and the second arched plate 3 are arranged in mirror-image orientation, and the entire structure forms a bidirectional pressure-bearing symmetrical curved surface with good load-bearing stability.

[0076] like Figure 11-14 As shown, a mechanical memory unit cell provided by an embodiment of the present invention includes a pressure-bearing member 4 and a support seat 5 arranged at intervals, and a plurality of the above-mentioned mechanical memory units are stacked between the pressure-bearing member 4 and the support seat 5. The pressure-bearing member 4 and the support seat 5 are used to bear the load so that the second arch plate 3 of the mechanical memory unit of each layer is reversely convex and deformed; and when the load is removed, the mechanical memory unit of each layer: when the first frame 11 and the second frame 12 are not connected, the second arch plate 3 automatically recovers; when the first frame 11 and the second frame 12 are connected, the second arch plate 3 maintains the deformed configuration.

[0077] In this optional embodiment, the mechanical memory cell is composed of a pressure-bearing part 4 and a support seat 5, and a plurality of mechanical memory units stacked therebetween. The pressure-bearing part 4, the multi-layer mechanical memory units and the support seat 5 form a continuous mechanical transmission chain. When the pressure-bearing part 4 and the support seat 5 are subjected to load, the multi-layer mechanical memory units therebetween will also be subjected to the load, which can cause the second arch plate 3 of the mechanical memory unit of each layer to convexly deform in the opposite direction, and when the load is removed, the mechanical memory unit of each layer: when the first frame 11 and the second frame 12 are not connected, the second arch plate 3 automatically restores; when the first frame 11 and the second frame 12 are connected, the second arch plate 3 maintains the deformed configuration.

[0078] That is, the initial state of each layer of mechanical memory cells is predefined by the connection between the first frame 11 and the second frame 12, forming a hidden state encoding layer. Activation is achieved once under a uniform external load, and the height of the entire unit cell is determined by the combination of the states of each layer, forming a programmable discrete height state. Each height state corresponds to unique spatial encoding information, so that the memory information is embedded in the structure in the form of the frame connection state. Externally, it only appears as a change in the unit cell height, achieving decoupling of the physical layer and the information layer, forming a predefined memory storage with hidden memory properties. In addition, each mechanical memory unit cell structure can be activated by applying and canceling force once, which has efficient memory activation characteristics.

[0079] Specifically, the first arched plate 2 and the second arched plate 3 are generally stacked in a vertical direction, the pressure-bearing member 4 is arranged at the top, the support seat 5 is arranged at the bottom, and the external force is applied in the vertical direction. The axes of the first arched plate 2 and the second arched plate 3 are both horizontal straight lines.

[0080] Take the example of a mechanical memory cell structure composed of four mechanical memory units stacked together. Figure 15As shown, a represents the first and second frames 11, 12 of each layer of mechanical memory cells being unconnected, and the height remaining unchanged after load activation. Be represents the first and second frames 11, 12 of the mechanical memory cells in the first, second, third, and fourth layers, connected, respectively. After load activation, the resulting height decreases in a step-like manner. In specific use, state a is defined as "0." When the first and second frames 11, 12 of a single layer of mechanical memory cells are connected, the initial state of the mechanical memory cell is defined as state "1c," and its activation state is defined as "1" by pressing one button. When the first and second frames 11, 12 of a second layer of mechanical memory cells are connected, the initial state of the mechanical memory cell is defined as state "2c," and its activation state is defined as "2" by pressing one button. When the first and second frames 11, 12 of a third layer of mechanical memory cells are connected, the initial state of the mechanical memory cell structure is defined as state "3c," and its activation state is defined as "3" by pressing one button. When the first and second frames 11, 12 of a fourth layer of mechanical memory cells are connected, the initial state of the mechanical memory cell structure is defined as state "4c," and its activation state is defined as "4" by pressing one button. This makes it possible to implement rewritable memory tasks for a variety of target information, with the characteristics of large memory capacity and efficient activation.

[0081] Optionally, along the direction from the pressure-bearing part 4 to the support seat 5: the first arch plate 2 of the first layer of mechanical memory unit is connected to the pressure-bearing part 4; the second arch plate 3 of the j-th layer of mechanical memory unit is connected to the first arch plate 2 of the j+1-th layer of mechanical memory unit; the arch top of the second arch plate 3 of the i-th layer of mechanical memory unit is connected to the support seat 5; wherein i is the number of layers of mechanical memory units, and j is any positive integer less than i.

[0082] In this optional embodiment, along the stacking direction from the pressure-bearing part 4 to the support seat 5, the first arch plate 2 of the mechanical memory unit at one end is connected to the pressure-bearing part 4, and the second arch plate 3 of the mechanical memory unit at the other end is connected to the pressure-bearing part 4. The arch tops of the first arch plates 2 of the two adjacent layers of mechanical memory units are connected to the arch tops of the second arch plates 3, thereby forming a continuous mechanical transmission chain. Applying force to the pressure-bearing part 4 and the support seat 5 can cause the second arch plates 3 of each layer to convexly deform in the opposite direction; after the force is removed, the second arch plates 3 of each layer automatically recover or maintain the deformed configuration.

[0083] Alternatively, as Figure 8-14 As shown, the arch top of the first arch plate 2 is provided with a connecting protrusion 21, and the arch top of the second arch plate 3 is provided with a connecting groove 31. The connecting grooves 31 of the mechanical memory units of two adjacent layers are adapted to fit with the connecting protrusion 21 to achieve the connection of the mechanical memory units of the two adjacent layers.

[0084] In this optional embodiment, the mechanical memory units of two adjacent layers are connected by the connecting groove 31 and the connecting protrusion 21, which is simple in structure and easy to assemble and disassemble. In addition, the connecting protrusion 21 and the connecting groove 31 are preferably connected by interference fit, and the connecting groove 31 and the connecting protrusion 21 are preferably rectangular in cross-section.

[0085] like Figure 8 and Figure 9 As shown, to enhance the load-bearing capacity of the first arched plate 2, a reinforcement block 22 is provided on the inner side of the arch of the first arched plate 2. To strengthen the structural strength of the first and second frames 11, 12, the frame body outside the slot 15 is raised upward, increasing the frame thickness. Furthermore, the connecting protrusions 21 on the first arched plate 2 of the first-layer mechanical memory unit can be designed larger to provide a more stable connection with the pressure-bearing member 4 and transfer load.

[0086] Alternatively, as Figure 13 As shown, the pressure-bearing member 4 is in a plate shape, and a limiting slot 41 is provided on the plate body. The limiting slot 41 is used to fit and engage with the connecting protrusion 21 of the first layer of mechanical memory unit.

[0087] In this optional embodiment, the pressure-bearing member 4 adopts a plate-type structural design, and a limiting slot 41 is provided on the plate body. The slot is connected to the connecting protrusion 21 of the first-layer mechanical memory unit, preferably an interference fit connection, to achieve precise positioning and load transfer.

[0088] Alternatively, as Figure 14 As shown, the support seat 5 includes a frame 51 and a third arch plate 52. The two ends of the third arch plate 52 are respectively fixed on a pair of sides of the frame 51. The arch top of the third arch plate 52 is provided with a limiting protrusion 53. The limiting protrusion 53 is adapted to fit in the connecting groove 31 of the n-th layer mechanical memory unit.

[0089] In this optional embodiment, the support seat 5 is composed of a frame 51 and a third arch plate 52. The third arch plate 52 spans between the opposite sides of the frame 51, and its arch top is provided with a limiting protrusion 53, which is connected to the connecting groove 31 of the last layer of mechanical memory unit, preferably by an interference fit connection, to achieve load transfer and structural closure.

[0090] Specifically, the structure of the third arch plate 52 can be designed to have the same structural dimensions as the first arch plate 2, and the structural dimensions of the frame 51 can be designed to have the same structural dimensions as the frame formed by connecting the first frame 11 and the second frame 12, so that the overall structure of the mechanical memory cell structure is reasonable.

[0091] It should be noted that in order to facilitate the observation of the height at the top of the mechanical memory unit, the plate-shaped pressure-bearing member 4 is located at the top, so Figure 11 and Figure 12 The mechanical memory unit in Figure 8 In the middle, the second arch plate 3 is placed upside down, that is, the second arch plate 3 is at the bottom and the first arch plate 2 is at the top. In addition, since the mechanical memory unit has a certain symmetry, the left and right states of the mechanical memory units of each layer can be the same when stacked, or they can be as follows: Figure 11 and Figure 12 The left and right states of the mechanical memory units in each layer are shown to be different.

[0092] like Figure 16 and 17 As shown, an embodiment of the present invention provides a mechanical memory device, which is characterized by comprising a base plate 6 on which a plurality of the above-mentioned mechanical memory cells are arranged.

[0093] In this embodiment, multiple mechanical memory cells are integrated on a base plate 6 to form a mechanical memory device. The information stored in each mechanical memory cell is combined to form a mechanical memory device that can store a huge amount of information to meet usage requirements.

[0094] Alternatively, as Figure 18 As shown, a plurality of concave positions 61 are provided on the bottom plate 6, and the concave positions 61 are used to place the support base 5 of the mechanical memory unit. Specifically, the concave positions 61 are adapted to fit with the surrounding frame 51 of the support base 5 to achieve the positioning of the mechanical memory unit.

[0095] Optionally, multiple mechanical memory cells are arranged in a rectangular array on the bottom plate 6 to form a high-density information storage matrix, which expands the information storage capacity exponentially. Figure 16 The structure of a 3*3 rectangular array is shown as follows: Figure 17 Shown is the structure of a 4*4 rectangular array.

[0096] It should be noted that the mechanical memory device is scalable. By increasing the size of the base plate 6 and the number of brain-like mechanical memory cells, it can achieve memory tasks for more complex and larger information. As long as the preparation methods are met, this mechanical device can also achieve memory tasks in a smaller size. Theoretically, a mechanical memory device composed of L layers, m rows and n columns of mechanical memory cells can achieve 2 L*m*n A memory property.

[0097] Optionally, the number of layers of the mechanical memory units of the plurality of mechanical memory cells is the same, that is, the mechanical memory cells are all of a standard structure, which facilitates the collection and acquisition of information.

[0098] An embodiment of the present invention provides a method for using a mechanical memory device, comprising the following steps S10-S30.

[0099] Step S10: connecting or disconnecting the first frame 11 and the second frame 12 of each layer of mechanical memory cells of each mechanical memory unit according to a predetermined setting.

[0100] Based on the target information to be stored and the encoding rules, the first and second frames 11 and 12 of each mechanical memory unit layer are selectively opened and closed to construct an initial configuration matrix. The specific connection or opening operation can be performed manually or mechanically. At this point, the mechanical memory device after pre-encoding is roughly the same as the mechanical memory device before encoding, achieving hidden target information memory.

[0101] Step S20: applying a pressing force to cause the second arched plates 3 of each layer of mechanical memory units of all mechanical memory cells to convexly deform in the reverse direction, and then removing the pressing force.

[0102] Usually, a load is applied to the pressure-bearing parts 4 of all mechanical memory cells at one time, and a precise pressure control system is used to make the second arched plates 3 of each layer of mechanical memory units of all mechanical memory cells undergo controllable reverse convex deformation, and load unloading is performed after the deformation stabilizes.

[0103] Step S30: Acquire the height information of each mechanical memory cell.

[0104] Specifically, for example, a laser displacement sensor array can be used to perform non-contact height scanning on each mechanical memory cell to generate a three-dimensional shape data set, and the pre-stored data or target information can be obtained accordingly.

[0105] Optionally, the method further includes step S40: disconnecting the first border 11 and the second border 12 of each layer of mechanical memory cells of each mechanical memory unit, erasing the memory state, so as to encode other information for use.

[0106] like Figure 19 The figure shows the encoding, activation, and erasure process of target information in a 3*3 rectangular array mechanical memory device. Each of the nine mechanical memory cells in this mechanical memory device has four layers of mechanical memory cells. After initial encoding in step S10, the number of layers of connection between the first frame 11 and the second frame 12 of each mechanical memory cell, from left to right and from top to bottom, is: 4, 2, 0, 2, 0, 2, 0, 2, 4. The corresponding initial encoding states are: 4c, 2c, 0, 2c, 0, 2c, 0, 2c, 4c. After a single press (activation in step S20), the corresponding activation states are: 4, 2, 0, 2, 0, 2, 0, 2, 4. At this point, the stored information can be retrieved using the height information of each mechanical memory cell (step S30). Subsequently, when additional information needs to be stored, the mechanical memory device erases the previously stored information (step S40). After erasure, the first frame 11 and the second frame 12 of each layer of mechanical memory cells in each mechanical memory cell are disconnected, and the corresponding initial encoding states are all 0.

[0107] like Figure 20 As shown, the process of encoding → activating → erasing target information by a mechanical memory device with a 4*4 rectangular array is demonstrated.

[0108] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
