Description
Technical Field
[0001] The present invention belongs to the interdisciplinary field of mechanics and computer science, and specifically relates to a mechanical logic operation system based on multi-order buckling instability of bilaterally constrained beams. Background Art
[0002] For thousands of years, computing and information processing were based on mechanical mechanisms. Representative mechanical analog computers include knots, abacus, planimeter, harmonic analyzer, and differential analyzer. In recent years, electronic computers have gradually replaced mechanical analog computers with their advantages of miniaturization and integration. However, electronic computers rely on a well-defined operating platform that requires certain computing resources and power consumption, and lack reconfigurability and reprogrammability. Furthermore, electronic computers cannot respond to the environment, that is, they cannot sense environmental information such as force and temperature to make decisions. Therefore, it is meaningful to enhance traditional electronic computers and develop intelligent computers with reconfigurable, reprogrammable, and environmentally interactive capabilities.
[0003] In recent years, scientists have proposed an unconventional mechanical computational strategy. This strategy integrates ideas from computer science, structural engineering, and materials science, utilizing mechanical mechanisms to process information. Beyond traditional mechanical simulation computers and electronic computers, this new mechanical computational system utilizes various subtle mechanisms to sense and process information about the external environment. Its structural responses or mechanical properties, such as deformation configuration, stiffness, and Poisson's ratio, serve as the medium for information processing. This mechanical computational strategy holds promise for the development of intelligent computers with reconfigurable, reprogrammable, and environmentally interactive capabilities. Under axial compression, a bilaterally constrained beam can achieve higher buckling modes than an unconstrained beam. As axial pressure or displacement increases, an unconstrained beam remains in the first-order buckling mode, with increasing lateral deflection. However, a bilaterally constrained beam, due to the bilateral constraints limiting its lateral deflection, will transition from the first-order buckling mode to a higher-order buckling mode (i.e., the third-order buckling mode). The buckling mode step response of a bilaterally constrained beam is well-suited as a physical foundation for information processing, enabling the construction of mechanical computational systems capable of performing complex computations and information processing, such as logical operations.
[0004] In the present invention, considering the lack of reconfiguration, reprogrammability and environmental interaction capabilities of traditional electronic computers, the present invention proposes a mechanical logic operation system based on the multi-order buckling instability of a double-sided constrained beam under axial compression. The problem solved by the present invention is that the system is based on the buckling mode step of the double-sided constrained beam under axial compression. Through ingenious structural design, it utilizes conventional materials such as polylactic acid and polylactic acid / carbon fiber composite materials to realize the logic operation function under the mechanical von Neumann architecture, providing a method for building an intelligent mechanical computer with reconfiguration, reprogrammability and information processing capabilities. The innovation of the present invention lies in the realization of the logic operation function under the von Neumann architecture through structural and material innovation and the utilization of the multi-order buckling instability mechanical response of the double-sided constrained beam; the mechanical input module and digital output module based on the double-sided constrained beam switch and LED light are easy to disassemble and assemble, giving the system excellent reconfiguration and reprogrammability; the signal input of the double-sided constrained beam switch is controlled by axial pressure or compression displacement. Therefore, the system also provides a strategy for realizing an intelligent mechanical computer that interacts with the pressure environment (i.e., processes pressure information in the environment). Summary of the Invention
[0005] Aiming at the problem that traditional electronic computers lack reconfigurability, reprogrammability and environmental interaction capabilities, the present invention proposes a mechanical logic operation system based on multi-order buckling instability of bilaterally constrained beams under axial compression.
[0006] The object of the present invention is achieved through the following technical solutions: a mechanical logic operation system based on multi-order buckling instability of bilaterally constrained beams, the system comprising a mechanical input module, a digital output module, a battery, and a wire;

[0008] The two-side restraint beam switches 1 and 2, as well as the base, are all manufactured in an integrated manner using dual-nozzle 3D printing technology. The number and combination of the two-side restraint beam switches 1 and 2 are determined by pre-implemented logical operation functions. The base is made of polylactic acid.
[0009] The double-sided restraint beam switch 1 is composed of a conductive beam, a conductive part 1 of switch 1, a conductive part 2 of switch 1, and a non-conductive part of switch 1. The double-sided restraint beam switch 2 is composed of a conductive beam, a conductive part 1 of switch 2, a conductive part 2 of switch 2, and a non-conductive part of switch 2. The conductive part is made of a polylactic acid / carbon fiber composite material, and the non-conductive part is made of polylactic acid.
[0010] Furthermore, the first-order buckling mode and the third-order buckling mode of switch 1 and switch 2 of the bilaterally constrained beam are abstracted as binary bits 0 and 1, respectively;
[0011] Furthermore, for the double-sided constrained beam switch 1 under axial compression, when the conductive beam is in the first-order buckling mode, the conductive beam contacts the non-conductive part of the switch 1, and the double-sided constrained beam switch 1 is in the open state; when the conductive beam is in the third-order buckling mode, the conductive beam connects the conductive part 1 and the conductive part 2 of the switch 1, and the double-sided constrained beam switch 1 is in the closed state;
[0012] Furthermore, for the double-sided constrained beam switch 2 under axial compression, when the conductive beam is in the first-order buckling mode, the conductive beam connects the conductive part 1 and the conductive part 2 of the switch 2, and the double-sided constrained beam switch 2 is in a closed state; when the conductive beam is in the third-order buckling mode, the conductive beam contacts the non-conductive part of the switch 2, and the double-sided constrained beam switch 2 is in an open state.
[0013] Furthermore, the digital output module is composed of LED lights plugged into the jacks of the breadboard; the off and on states of the LED lights are defined as digital signals 0 and 1 respectively; the number of LED lights is determined by the pre-implemented logic operation function;
[0014] Furthermore, by connecting the mechanical input module, digital output module and battery to build a circuit through wires, eight basic logic gates can be realized, namely Buffer, NOT, AND, OR, NAND, NOR, XOR and XNOR gates;
[0015] Furthermore, a buffer gate can be realized by constructing a mechanical input module using a single double-sided constrained beam switch.
[0016] Furthermore, a NOT gate can be realized by constructing a mechanical input module using a single double-sided constrained beam switch.
[0017] Furthermore, by using two double-sided constraint beam switches connected in series or in parallel to construct a mechanical input module, AND and OR gates can be realized respectively.
[0018] Furthermore, by using two double-sided constraint beam switches connected in parallel or series to construct a mechanical input module, NAND and NOR gates can be realized respectively;
[0019] Furthermore, unlike AND, OR, NAND, and NOR gates, XOR and XNOR gates require two bilaterally constrained beam switches 1 and two bilaterally constrained beam switches 2 to construct two parallel branches of the mechanical input module;
[0020] Furthermore, by combining the above eight basic logic gates, we can construct arbitrarily complex logic circuits and implement arbitrarily complex logic operations, such as half adders and full adders.
[0021] Beneficial effects of the present invention: Taking into account the lack of reconfigurable, reprogrammable and environmental interactive capabilities of traditional electronic computers, the present invention proposes a mechanical logic operation system based on the multi-order buckling instability of a bilaterally constrained beam under axial compression. The innovation of the present invention lies in that through structural and material innovation, the multi-order buckling instability mechanical response of the bilaterally constrained beam is utilized to realize the logic operation function under the von Neumann architecture; the mechanical input module and digital output module based on the bilaterally constrained beam switch and the LED light are easy to disassemble and assemble, giving the system excellent reconfigurable and reprogrammable performance; the signal input of the bilaterally constrained beam switch is controlled by axial pressure or compression displacement, so the system also provides a strategy for realizing an intelligent mechanical computer that interacts with the pressure environment (i.e., processes pressure information in the environment). Based on the buckling mode step of the bilaterally constrained beam under axial compression, the present invention realizes the logic operation function under the von Neumann architecture at the mechanical level through ingenious structural design and the use of conventional materials such as polylactic acid and polylactic acid / carbon fiber composite materials, providing a method for constructing an intelligent mechanical computer with reconfigurable, reprogrammable and information processing capabilities.

DETAILED DESCRIPTION
[0036] The specific embodiments of the present invention are further described in detail below with reference to the accompanying drawings.
[0037] like Figures 1 to 13 As shown, the present invention provides a mechanical logic operation system based on multi-order buckling instability of bilaterally constrained beams, including a mechanical input module 1, a digital output module 2, a battery 3 and a wire 4.
[0038] like Figure 1 As shown, the mechanical input module 1 is composed of a double-sided constraint beam switch 1 101 and a switch 2 102 embedded in a groove 104 of a base 103 .
[0039] The first and second bilateral restraint beam switches 101 and 102, as well as the base 103, are all fabricated using dual-nozzle 3D printing technology. The number and combination of the first and second bilateral restraint beam switches 101 and 102 is determined by pre-implemented logic operations. The base 103 is made of polylactic acid.
[0040] like Figure 2 As shown, double-sided restraint beam switch 101 comprises a conductive beam 105, switch 1 conductive portion 1 106, switch 1 conductive portion 2 107, and switch 1 non-conductive portion 108. Double-sided restraint beam switch 2 102 comprises a conductive beam 105, switch 2 conductive portion 1 109, switch 2 conductive portion 2 110, and switch 2 non-conductive portion 111. The conductive portion is made of a polylactic acid / carbon fiber composite material, while the non-conductive portion is made of polylactic acid.
[0041] like Figure 3 As shown, the first-order buckling mode and the third-order buckling mode of the double-sided constrained beam switch 1 101 and the switch 2 102 are abstracted as binary bits 0 and 1, respectively.
[0042] For the double-sided constrained beam switch 101 under axial compression, when the conductive beam 105 is in the first-order buckling mode, the conductive beam 105 contacts the non-conductive part 108 of the switch 1, and the double-sided constrained beam switch 101 is in the disconnected state; when the conductive beam 105 is in the third-order buckling mode, the conductive beam 105 connects the conductive part 106 of the switch 1 and the conductive part 2 107, and the double-sided constrained beam switch 101 is in the closed state.
[0043] For the double-sided constrained beam switch 2 102 under axial compression, when the conductive beam 105 is in the first-order buckling mode, the conductive beam 105 connects the conductive part 1 109 and the conductive part 2 110 of switch 2, and the double-sided constrained beam switch 2 102 is in a closed state; when the conductive beam 105 is in the third-order buckling mode, the conductive beam 105 contacts the non-conductive part 111 of switch 2, and the double-sided constrained beam switch 2 102 is in an open state.
[0044] like Figure 4 As shown, the digital output module 2 is composed of an LED lamp 201 inserted into a socket 203 of a breadboard 202.
[0045] The off and on states of the LED lamp 201 are respectively defined as digital signals 0 and 1. The number of the LED lamps 201 is determined by the pre-implemented logic operation function.
[0046] like Figures 5 to 12 As shown, the mechanical input module 1, the digital output module 2 and the battery 3 are connected by wires 4 to construct a circuit, which can realize eight basic logic gates, namely Buffer, NOT, AND, OR, NAND, NOR, XOR and XNOR gates.
[0047] like Figure 5 As shown, a single double-sided constrained beam switch 101 is used to construct a mechanical input module 1, which can realize a buffer gate.
[0048] When the conductive beam 105 of the double-sided constraint beam switch 101 is in the first-order buckling mode (i.e., the Buffer gate input signal is 0), the double-sided constraint beam switch 101 is disconnected, causing the circuit to be disconnected, and the LED light 201 is not lit (i.e., the Buffer gate output signal is 0); conversely, when the conductive beam 105 of the double-sided constraint beam switch 101 is in the third-order buckling mode (i.e., the Buffer gate input signal is 1), the double-sided constraint beam switch 101 is closed, causing the circuit to be connected, and the LED light 201 is lit (i.e., the Buffer gate output signal is 1).
[0049] like Figure 6 As shown, a single double-sided constrained beam switch 102 is used to construct a mechanical input module 1, which can realize a NOT gate.
[0050] When the conductive beam 105 of the double-sided constraint beam switch 102 is in the first-order buckling mode (i.e., the NOT gate input signal is 0), the double-sided constraint beam switch 102 is closed, causing the circuit to be turned on, and the LED light 201 is on (i.e., the NOT gate output signal is 1); conversely, when the conductive beam 105 of the double-sided constraint beam switch 102 is in the third-order buckling mode (i.e., the NOT gate input signal is 1), the double-sided constraint beam switch 102 is disconnected, causing the circuit to be disconnected, and the LED light 201 is not on (i.e., the NOT gate output signal is 0).
[0051] like Figure 7 and 8 As shown, the mechanical input module 1 is constructed by using two double-sided constraint beam switches 101 connected in series or in parallel, and AND and OR gates can be realized respectively.
[0052] For the AND gate, only when the conductive beams 105 of both bilaterally constrained beam switches 101 are in the third-order buckling mode (i.e., both inputs of the AND gate are signal 1), the circuit is connected and the LED light 201 is on (i.e., the AND gate outputs signal 1). For the OR gate, only when the conductive beams 105 of at least one bilaterally constrained beam switch 101 are in the third-order buckling mode (i.e., at least one input of the OR gate is signal 1), the circuit is connected and the LED light 201 is on (i.e., the OR gate outputs signal 1).
[0053] like Figure 9 and 10 As shown, the mechanical input module 1 is constructed by using two double-sided constraint beam switches 102 connected in parallel or in series, which can respectively realize NAND and NOR gates.
[0054] For a NAND gate, the circuit is conductive and the LED 201 is illuminated (i.e., the NAND gate outputs a signal of 1) only when at least one of the two-sided constrained beam switches 102 is in the first-order buckling mode (i.e., at least one of the NAND gate inputs is a signal of 0). For a NOR gate, the circuit is conductive and the LED 201 is illuminated (i.e., the NOR gate outputs a signal of 1) only when both conductive beams 105 of the two two-sided constrained beam switches 102 are in the first-order buckling mode (i.e., both of the NOR gate inputs are signals of 0).
[0055] like Figure 11 and 12 As shown, unlike AND, OR, NAND and NOR gates, XOR and XNOR gates require two double-sided constraint beam switches 101 and two double-sided constraint beam switches 102 to construct two parallel branches of the mechanical input module 1.
[0056] For the XOR gate, one branch of the mechanical input module 1 consists of a series connection between the left-side double-side restraint beam switch 101 and the right-side double-side restraint beam switch 2 102. The other branch consists of a series connection between the left-side double-side restraint beam switch 2 102 and the right-side double-side restraint beam switch 1 101. Only when the left and right switches are in different buckling modes (i.e., when the XOR gate input signals are 01 or 10), the circuit is connected and the LED 201 illuminates (i.e., when the XOR gate outputs a signal of 1).
[0057] For the XNOR gate, one branch of the mechanical input module 1 consists of two bilaterally constrained beam switches 101 connected in series, while the other branch consists of two bilaterally constrained beam switches 102 connected in series. Only when the left and right switches are in the same buckling mode (i.e., XNOR gate input signal 00 or 11) will the circuit be conductive and LED 201 illuminate (i.e., XNOR gate output signal 1).
[0058] By combining the above 8 basic logic gates, we can construct arbitrarily complex logic circuits and implement arbitrarily complex logic operations, such as half adders, full adders, etc.
[0059] like Figure 13 As shown, the half adder is formed by a combination of AND and XOR gates, its mechanical input module 1 is composed of the mechanical input modules 1 of the AND and XOR gates connected in parallel, and its digital output module has two LED lights 201, which are respectively connected to the mechanical input modules 1 of the AND and XOR gates.
[0060] When the conductive beams 105 of the left and right switches are both in the first-order buckling mode (i.e., half-adder input signal 00), both LED lights 201 are off (i.e., half-adder output signal 00); when the left and right switches are in different buckling modes (i.e., half-adder input signals 01 or 10), the LED lights 201 corresponding to the AND gate are off, and the LED lights 201 corresponding to the XOR gate are on (i.e., half-adder output signal 01); when the conductive beams 105 of the left and right switches are both in the third-order buckling mode (i.e., half-adder input signal 11), the LED lights 201 corresponding to the AND gate are on, and the LED lights 201 corresponding to the XOR gate are off (i.e., half-adder output signal 10).
[0061] When the system of the present invention performs logical operations within the von Neumann architecture, the number and combination of switches 101 and 102 for the bilateral restraining beam, as well as the number of LEDs 201, are determined based on the pre-implemented logical operations. Then, by connecting the mechanical input module 1, digital output module 2, and battery 3 via wires 4 to form a circuit, the specific logical operations can be performed.
[0062] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
