Abstract

This invention proposes an adaptive facade system and integration method for flexible membrane structure buildings that dynamically responds to user and environmental needs. The system, through the collaborative operation of a data acquisition module, a deformation control module, a motion execution module, and the flexible membrane structure, collects real-time ambient light data and user distance data. The deformation control module processes and analyzes the data using a preset algorithm to generate control commands, which are input to the motion execution module via electrical signals. The motion execution module, through servo motors and lightweight aluminum alloy rods, drives the aluminum ribs to bend and extend, thereby influencing the morphological changes of the flexible membrane structure. Based on the physical properties resulting from the deformation of the flexible membrane structure, the system achieves effects such as adjusting lighting, ventilation, and heat insulation on the facade, responding to environmental changes and user needs, and optimizing the comfort and energy efficiency of the building's interior. This system not only improves indoor environmental comfort but also saves energy and provides a dynamically changing building facade effect, combining aesthetics and functionality.

Description

Technical Field

[0001] This invention relates to the field of building skin systems, and in particular to a flexible membrane structure building adaptive skin system and integration method that dynamically responds to user and environmental needs. Background Technology

[0002] Building skins play a crucial role in the overall performance and user experience of buildings. Their initial function focused primarily on protecting the building's internal structure and mitigating the adverse effects of external natural factors. The continuous evolution of building technology has driven the development of building skins towards a fusion of aesthetics and functionality. Building skins serve as a medium for heat and mass transfer between indoor and outdoor environments, and are an important system for reducing building energy consumption, improving building green performance, and creating a healthy living environment. Adaptive building skins further enhance the accuracy and flexibility of building skin systems in responding to dynamic demands, and have become a forward-looking area of ​​development for building envelopes in the digital age.

[0003] However, in this development process, early building skin designs were mostly based on single functional requirements or purely aesthetic considerations, lacking a coordinated response to the objective environment and user needs. While existing adaptive skin systems have achieved a certain degree of environmental responsiveness, they suffer from deficiencies in data acquisition, adjustment precision, and aesthetic integration. Data acquisition is not accurate or comprehensive enough to obtain real-time information such as user status and building interior and exterior environmental characteristics; adjustment precision is limited, making it difficult to achieve refined control of the building skin and accurately meet the personalized needs of different areas and users. Summary of the Invention

[0004] The purpose of this invention is to address the problems in existing technologies by proposing a flexible membrane structure building adaptive skin system and integration method that dynamically responds to user and environmental needs. This system integrates multiple modules working collaboratively to achieve real-time perception and precise coordinated response to environmental data and user demands, effectively improving the quality of the building's indoor environment, optimizing building energy efficiency, and creating a dynamically aesthetic building facade.

[0005] This invention is achieved through the following technical solution: This invention proposes a flexible membrane structure building adaptive skin system that dynamically responds to user and environmental needs. The adaptive skin system includes a data acquisition module, a deformation control module, several motion execution modules, and a flexible membrane structure. The motion execution modules are tightly connected to the flexible membrane structure using Velcro straps 7, and bolted to L-shaped steel columns 13 via L-shaped steel 12. The channel steel columns 13 are fixed to the outer facade of the building 14 via adapters and embedded parts. A servo motor 1 is installed on each motion execution module. The control end of the servo motor 1 is electrically connected to the signal output end of the deformation control module via a wired connection, and the signal input end of the deformation control module is communicatively connected to the output end of the data acquisition module. After receiving the motion command from the deformation control module, the motion execution module changes accordingly. The built-in components rotate via the servo motor 1, driving the linkage system to complete the linkage, ultimately causing the flexible membrane structure to change according to the algorithm results. The tension, expansion, and contraction deformation of the flexible membrane structure achieves the effect of regulating ventilation and lighting.

[0006] Furthermore, several motion execution modules are equipped with m*n servo motors 1 and drive gears 2 mounted on the rotating shafts of the servo motors 1. The servo motors 1 are arranged in a plane parallel to the building facade at horizontal distances x and vertical distances y. There are n motion execution modules in each row and m motion execution modules in each column. m and n are arbitrary natural numbers, and the values ​​of m and n can be adjusted according to the building facade. The horizontal distance x is determined according to the expected tensioning effect, and the vertical distance y is set to an initial value based on the operational safety distance between the rods and the length of the rods themselves.

[0007] Furthermore, the servo motor 1 is fixed to the plastic bracket 10 by bolts. The plastic bracket 10 is connected and fixed to the L-shaped steel 12. The driven rack 3 is placed in the sliding groove of the plastic bracket 10 and meshes with the driving gear 2. A lightweight aluminum ring 4 with rounded square holes is welded to the end of the driven rack 3, and a lightweight telescopic aluminum strip 5 is fixed in the lightweight aluminum ring 4 by bolts.

[0008] Furthermore, the flexible membrane structure includes a flexible membrane 6 and nylon fasteners 7 connected flexibly. The nylon fasteners 7 at the edge of the flexible membrane 6 are continuously arranged and fixed to the outer aluminum frame. Several lightweight aluminum alloy rods are welded to the aluminum frame rods 8 at one end and to the building 14 by welding through embedded parts at the other end. In the flexible membrane 6, the nylon fasteners 7 fixed on the inner side are distributed in a dotted pattern. The nylon fasteners 7 are connected to the lightweight aluminum rings 4 and are distributed in a wavy pattern along the edge of the membrane surface. The flexible membrane 6 is in contact with the lightweight telescopic aluminum strips 5 but is not fixed. It deforms according to the characteristics of the aluminum strips themselves and produces corresponding dynamic changes.

[0009] Furthermore, the data acquisition module includes an indoor illuminance sensor 15 installed inside the building 14 at the user's working plane, and n distance sensors 16 installed inside the building 14 in the vertical plane of the surface; the indoor illuminance sensor 15 has a measurement accuracy of ±0.1 lux and a measurement range of 0-1000 lux; the distance sensors 16 have a measurement accuracy of ±0.01 meters and a measurement range of 0-10 meters.

[0010] Furthermore, the deformation control module is communicatively connected to the data acquisition module, and is used to receive indoor illuminance data and user distance data, analyze and judge the ambient lighting conditions and user status according to a preset algorithm, and generate control commands. The deformation control module includes a data processing unit and a control command generation unit. The data processing unit is used to preprocess the acquired indoor illuminance data and user distance data, and input the preprocessed data into the preset algorithm for analysis. The control command generation unit is used to generate control commands based on the processing results. The control commands include precise control parameters for the rotation angle and rotation direction of the servo motor 1.

[0011] Furthermore, the rotation amplitude of the servo motor 1 directly affects the forward and backward movement length of the driven rack 3. Each servo motor 1 will perform precise angular rotation according to the control command generated by the deformation control module, with a rotation accuracy of ±0.1 degrees and a response time of no more than 1000 milliseconds, thereby accurately controlling the direction and length of the rack movement, thereby driving the accurate deformation of the lightweight telescopic aluminum strip 5 and realizing precise control of the deformation of the flexible membrane 6; the flexible membrane 6 in each area is individually tensioned to meet the personalized ventilation, lighting and behavioral needs of each area.

[0012] The present invention also proposes an integration method based on the aforementioned building adaptive skin system, the method comprising the following steps:

[0013] Installation and fixing structure: Pre-embed channel steel columns 13 on the outer side of the building facade, with the spacing determined according to the building structure strength and surface system load; connect L-shaped steel 12 to channel steel columns 13 with bolts through adapters, ensuring rust prevention treatment at the connection; fix plastic brackets 10 to L-shaped steel 12, adjust the horizontal distance x to 0.3m and the vertical distance y to 0.3m to form an m×n servo motor matrix layout;

[0014] Motion execution module assembly: Servo motor 1 is vertically fixed to plastic bracket 10 by bolts to ensure precise meshing between drive gear 2 and driven rack 3; lightweight aluminum ring 4 is welded to the end of driven rack 3 and bolted to lightweight telescopic aluminum strip 5 to form a continuous XY plane transmission frame;

[0016] Data acquisition and deformation control module integration: Indoor illuminance sensors 15 are installed at the height of the user's working plane, one per 10㎡; distance sensors 16 are installed at 1m intervals along the vertical direction of the building facade, at a height of 1m above the ground; the deformation control module communicates with the sensors via Bluetooth 4.0 protocol and has a preset hierarchical control algorithm.

[0017] The present invention also proposes an electronic device, including a memory and a processor, wherein the memory stores a computer program, and the processor executes the computer program to implement the control algorithm.

[0018] The present invention also proposes a computer-readable storage medium for storing computer instructions, which, when executed by a processor, implement the control algorithm.

[0019] The beneficial effects of this invention are:

[0020] 1. Precise environmental regulation: Through comprehensive and accurate data collection and precise control algorithms, the system can sense changes in the environment and user needs in real time, and precisely adjust environmental parameters such as indoor lighting, ventilation and temperature, significantly improving indoor comfort.

[0021] 2. Energy saving and consumption reduction: The surface condition is automatically optimized according to environmental conditions, effectively utilizing natural energy and reducing artificial energy consumption. For example, when there is sufficient sunlight, the flexible membrane structure is adjusted to increase lighting and reduce lighting energy consumption; when ventilation is appropriate, the ventilation volume is increased to reduce the load on the air conditioning system.

[0022] 3. Integration of Aesthetics and Function: The dynamic changes of flexible membrane structures give buildings a unique appearance, creating a dynamic architectural aesthetic effect while meeting functional requirements, and enabling buildings to better integrate with the environment.

[0034] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Combination Figures 1-9This invention proposes a flexible membrane structure building adaptive skin system that dynamically responds to user and environmental needs. The adaptive skin system includes a data acquisition module, a deformation control module, several motion execution modules, and a flexible membrane structure. After the motion execution modules are connected to the flexible membrane structure, they are bolted to L-shaped steel and channel steel columns and are stably fixed to the outside of the building facade through adapters and embedded parts. Moreover, the fixed flexible membrane structure is welded to the embedded parts on the building facade by lightweight aluminum alloy rods as an auxiliary fixing method. Specifically, several motion execution modules are tightly connected to the flexible membrane structure using Velcro straps 7, and bolted to L-shaped steel 12 and channel steel columns 13. The channel steel columns 13 are fixed to the outer facade of the building 14 via adapters and embedded parts. A servo motor 1 is installed on each motion execution module. The control end of the servo motor 1 is electrically connected to the signal output end of the deformation control module via a wired connection. The signal input end of the deformation control module is communicatively connected to the output end of the data acquisition module. After receiving the motion command from the deformation control module, the motion execution module changes accordingly. The built-in components rotate through the servo motor 1, driving the rod system to complete the linkage, ultimately causing the flexible membrane structure to change according to the algorithm results. The tension, expansion, and contraction deformation of the flexible membrane structure achieves the effect of regulating ventilation and lighting.

[0036] Several motion execution modules are equipped with m*n servo motors 1 and drive gears 2 mounted on the rotating shafts of the servo motors 1. The servo motors 1 are arranged in a plane parallel to the building facade at horizontal distances x and vertical distances y. Each row of motion execution modules is n, and each column of motion execution modules is m. m and n are arbitrary natural numbers, and their values ​​can be adjusted according to the building facade. That is, the value range of m is determined based on the height of the building facade and the required adjustment accuracy, and the value range of n is determined based on the width of the building facade and the division of the adjustment area. The horizontal distance x is determined based on the expected tensioning effect and has a value range of 0.2-0.4m. The vertical distance y is set with an initial value based on the safe operating distance between the rods and the length of the rods themselves. In this invention, the distance y is set with an initial value based on an operating safe distance of not less than 0.25m between the rods.

[0037] Both the driving gear and the driven rack are made of lightweight aluminum. The driving gear has 36 teeth, and the driven rack's tooth pitch matches it. The length is determined within 0.3-0.5m according to actual transmission requirements. The servo motor is fixed to a plastic bracket with bolts, and the plastic bracket is connected to an L-shaped steel. The driven rack is placed in the sliding groove of the plastic bracket and meshes with the driving gear. After receiving a motion command, the servo motor rotates, driving the driving gear to rotate and thus driving the driven rack to reciprocate back and forth. Specifically, the servo motor 1 is fixed to the plastic bracket 10 with bolts, and the plastic bracket 10 is connected and fixed to the L-shaped steel 12. The driven rack 3 is placed in the sliding groove of the plastic bracket 10 and meshes with the driving gear 2. A lightweight aluminum ring 4 with rounded square holes is welded to the end of the driven rack 3, and a lightweight telescopic aluminum strip 5 is fixed inside the lightweight aluminum ring 4 with bolts. The sliding groove cross-section of the plastic card holder meshes with the cross-section of the driven rack, with an overlap of 0.15m in length. The driven rack, driven by a servo motor and a drive gear, reciprocates within the sliding groove, with a friction coefficient of 0.1. A lightweight aluminum ring with rounded square holes is welded to the end of the driven rack. The ring has an inner diameter of 3*70mm and an outer diameter of 5*80mm. A lightweight telescopic aluminum strip is bolted inside the lightweight aluminum ring. The lightweight telescopic aluminum strip has a cross-sectional dimension of 2*65mm and inherent elasticity. It can deform in a curve in the XY plane according to the endpoint fixed to the lightweight aluminum ring. When there is a positional difference in the X direction between two adjacent driven racks, the fixing point of the lightweight telescopic aluminum strip and the lightweight aluminum ring will change position in the X direction, causing tension in the lightweight telescopic aluminum strip between the two fixing points. The curve in the XY plane will change from the initial curve to a new curve. The driven rack continuously transmits power, driving the lightweight telescopic aluminum strip to move continuously, and the planar curve follows the changes.

[0038] The flexible membrane structure includes a flexible membrane 6 and nylon fasteners 7 connected flexibly. The nylon fasteners 7 on the edge of the flexible membrane 6 are continuously arranged and fixed to the outer aluminum frame. Several lightweight aluminum alloy rods are welded to the aluminum frame rods 8 at one end and to the building 14 by welding through embedded parts at the other end. In the flexible membrane 6, the nylon fasteners 7 fixed on the inner side are distributed in a dotted pattern. The nylon fasteners 7 are connected to the lightweight aluminum rings 4 and are distributed in a wavy pattern along the edge of the membrane surface. The flexible membrane 6 is in contact with the lightweight telescopic aluminum strips 5 but is not fixed. It deforms according to the characteristics of the aluminum strips themselves and produces corresponding dynamic changes. The deformation effect is not affected by excessive or insufficient friction. Specifically, the flexible membrane structure includes a flexibly connected flexible membrane and Velcro straps; the light transmittance of the flexible membrane material is 35%-65%, exhibiting semi-transparency, and its light transmittance changes with the degree of tension, achieving light environment regulation; the Velcro straps on the edge of the flexible membrane are continuously arranged and connected to the outer aluminum frame; several lightweight aluminum alloy rods are welded at one end to the aluminum frame rods and at the other end to the building through pre-embedded parts. The Velcro straps fixed on the inner side of the flexible membrane are distributed in a dotted pattern, connected to lightweight aluminum rings, and distributed in a wavy shape along the edge of the membrane surface. The flexible membrane has strong elasticity and plasticity, and exhibits significant changes in light and air transmission characteristics after tensioning. After the flexible membrane and the lightweight aluminum ring are fixed together with Velcro, the driven rack drives the lightweight aluminum ring at the end to reciprocate back and forth in the X direction. The contact point is directly tensioned, causing the flexible membrane to deform. Moreover, the lightweight telescopic aluminum strip that is in spatial contact with the flexible membrane serves as the supporting skeleton of the flexible membrane. During the transmission deformation process, the lightweight telescopic aluminum strip drives the flexible membrane to make up for the deformation in appearance, resulting in a variety of flexible membrane shapes.

[0039] The data acquisition module includes an indoor illuminance sensor 15 installed inside the building 14 at the user's working surface, and n distance sensors 16 installed inside the building 14 and on the vertical plane of the building's surface. The indoor illuminance sensor 15 has a measurement accuracy of ±0.1 lux and a measurement range of 0-1000 lux, enabling it to accurately collect indoor light intensity data. The n distance sensors 16 are installed inside the building and on the vertical plane of the building's surface at 1m intervals and at a height of 1m from the ground. The distance sensors 16 have a measurement accuracy of ±0.01 meters and a measurement range of 0-10 meters, enabling them to accurately obtain distance information between the user and the surface, providing data support for the precise adjustment of the system.

[0040] The deformation control module is communicatively connected to the data acquisition module and is used to receive indoor illuminance data and user distance data. It analyzes and judges the ambient lighting conditions and user status according to a preset algorithm and generates control commands. The deformation control module includes a data processing unit and a control command generation unit. The data processing unit performs preprocessing such as filtering and noise reduction on the collected indoor illuminance data and user distance data, and inputs the preprocessed data into the preset algorithm for analysis. The control command generation unit generates control commands based on the processing results. The control commands include precise control parameters such as the rotation angle and rotation direction of the servo motor 1. Specifically, the deformation control module and the data acquisition module are connected via Bluetooth, using Bluetooth 4.0 as the communication protocol. It receives indoor illuminance data and user distance data and analyzes and judges them using a preset algorithm. This algorithm is based on a large amount of experimental data and theoretical research, comprehensively considers multiple factors, and generates precise control commands through complex calculations and logical judgments. The control commands include parameters such as the rotation angle and rotation direction of the servo motor.

[0041] The rotation amplitude of the servo motor 1 directly affects the forward and backward movement length of the driven rack 3. Each servo motor 1 will perform precise angular rotation according to the control command generated by the deformation control module, with a rotation accuracy of ±0.1 degrees and a response time of no more than 1000 milliseconds, thereby accurately controlling the direction and length of the rack movement, thereby driving the accurate deformation of the lightweight telescopic aluminum strip 5 and realizing precise control of the deformation of the flexible membrane 6. The control degree of the servo motor 1 in each area can be adjusted accurately and instantly, and the flexible membrane 6 in each area is individually tensioned, thereby realizing the personalized ventilation, lighting and behavioral needs of each area.

[0042] The working principle and control process of the building adaptive skin system are as follows: The data acquisition module continuously collects indoor illuminance data and user distance data, and transmits them to the deformation control module. The data processing unit in the deformation control module analyzes the data, classifies the illuminance into three categories: weak light (illuminance < 150 lux), normal light (150-450 lux), and strong light (> 450 lux); and classifies the distance between the user and the nearest facade into two categories: close distance (distance < 1m) and far distance (distance ≥ 1m). The control command generation unit generates control commands according to a preset algorithm. The algorithm adopts hierarchical control logic: it prioritizes responding to user distance signals. When the user enters within 1m, the generated command will ultimately drive several servo motors in the control area to ultimately drive the membrane surface to concave inward to form a shading area. At the same time, it adjusts the concavity depth (10-30cm) and membrane surface tilt angle (0°-45°) in conjunction with the illuminance. When the user is far from the facade, the facade's shape and angle (0-30 degrees) are adjusted according to indoor illuminance. The control commands are electrically transmitted to individual servo motors in the motion execution module. Each individual servo motor rotates precisely according to the corresponding command, with a rotation accuracy of ±0.1 degrees and a response time of no more than 1000 milliseconds. Each servo motor drives the drive gear to rotate, which in turn drives the driven rack meshing with the drive gear to move back and forth along the X direction in the XY plane. The movement distance is precisely controlled by the rotation angle of the servo motor. The driven rack drives a lightweight telescopic aluminum strip within a lightweight aluminum ring welded to its end to move in the XY plane. The fixed point of the lightweight telescopic aluminum strip and the driven rack is subjected to force and moves in the X direction. Each lightweight telescopic aluminum strip extends and retracts in the XY plane. The corresponding curve deformation; the lightweight telescopic aluminum strip contacts the flexible membrane, and the force of traction or thrust is generated at the fixed point between the two to form the force point of deformation. In the linear contact area, the lightweight telescopic aluminum strip acts as a supporting skeleton to guide the flexible membrane structure to undergo tension and expansion. During the tensioning process, the thickness and texture density of the flexible membrane change, thereby producing changes in shading and ventilation characteristics, so as to realize the functions of facade lighting adjustment, ventilation and heat insulation to adapt to environmental changes and user needs; moreover, since the control command can control the tensioning of the flexible membrane in the area individually, it can meet the personalized ventilation, lighting and behavioral needs of each area.

[0043] The present invention also proposes an integration method based on the aforementioned building adaptive skin system, the method comprising the following steps:

[0044] Installation and fixing structure: Pre-embed channel steel columns 13 on the outer side of the building facade, with the spacing determined according to the building structure strength and surface system load; connect L-shaped steel 12 to channel steel columns 13 with bolts through adapters, ensuring rust prevention treatment at the connection; fix plastic brackets 10 to L-shaped steel 12, adjust the horizontal distance x to 0.3m and the vertical distance y to 0.3m to form an m×n servo motor matrix layout;

[0045] Motion execution module assembly: Servo motor 1 is vertically fixed to plastic bracket 10 by bolts to ensure precise meshing between drive gear 2 and driven rack 3; lightweight aluminum ring 4 is welded to the end of driven rack 3 and bolted to lightweight telescopic aluminum strip 5 to form a continuous XY plane transmission frame;

[0046] Flexible membrane structure laying: The edge of the flexible membrane 6 is fixed to the aluminum frame with continuous nylon fasteners 7; the aluminum frame is welded to the building embedded parts with lightweight aluminum alloy rods to ensure uniform initial tension of the flexible membrane 6; the nylon fasteners 7 distributed in a dotted pattern on the inner side of the flexible membrane 6 are connected to the lightweight aluminum rings 4 to form a wavy edge.

[0047] Data acquisition and deformation control module integration: Indoor illuminance sensors 15 are installed at the user's working plane height (1.2m), one per 10㎡; distance sensors 16 are installed at 1m intervals along the vertical direction of the building facade, at a height of 1m above the ground; the deformation control module communicates with the sensors via Bluetooth 4.0 protocol and has a preset hierarchical control algorithm.

[0048] Taking the south facade of an office building as an example, the system was installed and tested:

[0049] Reference Figure 1 The flexible membrane structure building adaptive skin system, which dynamically responds to the needs of users and the environment, has an initial state preset, that is, the initial extension and contraction position of the driven rack on the XY plane is zero, and the relative displacement of the driven rack in the groove of the plastic base is also zero. Before each adjustment of the flexible membrane shape change, the control command generation unit in the deformation control module will use the current relative position of the driven rack with respect to the initial state as part of the calculation data, and input it into the preset algorithm to generate control commands.

[0050] Reference Figures 1 to 5 This invention proposes a flexible membrane structure building adaptive skin system that dynamically responds to user and environmental needs. It mainly consists of a data acquisition module, a deformation control module, several motion execution modules, and a flexible membrane structure. This invention adjusts the external shape of the flexible membrane structure by receiving real-time indoor illuminance data and user distance data, thereby achieving adaptive skin regulation of the building's indoor light and heat environment and interaction with users. In this embodiment, the skin system has 24 motion execution modules arranged in four closely spaced rows, with six control modules in each row. Each motion execution module is system-numbered, with letters AF from left to right and numbers 1-4 from top to bottom. The module numbers are combinations of letters and numbers, i.e., A1 to F4.

[0051] Reference Figure 6In this embodiment, the skin system is in its initial state. The indoor illuminance data collected during the first time period is 200 lux, and the user's distance from the third-column motion execution module is 0.8m. The data is transmitted to the deformation control module. The control command generation unit calculates according to the pre-designed data processing method, determines that the current environment is low light and that there are user activity characteristics in some areas, simulates the most appropriate adjustment mode through an algorithm, and transmits it to the deformation control module.

[0052] Reference Figure 6 After the deformation control module sends a control command to the motion execution module, the servo motors in motion execution modules B1, B3, C2, C4, D1, and D3 rotate 720 degrees clockwise, and the driving gear drives the driven rack to move forward 0.25m along the X-axis. The servo motors in motion execution modules B2, B4, C1, C2, D2, and D4 remain stationary, and the driven rack does not change in the X-axis direction. The servo motors in motion execution modules A1-A4 and E1-E4 rotate 360 ​​degrees clockwise, and the driving gear drives the driven rack to move forward 0.125m along the X-axis. The servo motors in motion execution modules F1-F4 remain stationary, and the driven rack does not change in the X-axis direction. The X-coordinate of the driven rack in the XY plane changes, and the X-coordinate of the junction point of the lightweight telescopic aluminum strip fixed in the lightweight aluminum ring at its end also changes. The lightweight telescopic aluminum strip is stretched to different degrees at different positions, forming several different and special curves.

[0053] Lightweight telescopic aluminum strips provide spatial support through contact with the flexible membrane. Their own shape changes cause the flexible membrane to undergo morphological changes in different areas. The membrane stretches to its maximum deformation zone in areas closer to people, with a stretching depth of approximately 0.25m and a membrane surface tilt angle of 40°. At this point, users experience a significant ventilation effect from the flexible membrane, achieving optimal visual appeal to the building's exterior. In areas further away from users, the membrane stretches to a moderate deformation zone, with a stretching depth of approximately 0.125m and a membrane surface tilt angle of 20°. In these areas, indoor users perceive less change in lighting, and the ability to supplement indoor lighting from the outside is reduced.

[0054] After the deformation control module finishes operating, it continues to receive measurement data transmitted by the data acquisition module, judges data changes through the built-in data processing unit, and transmits the processed data into the control command generation unit for the next step of regulation.

[0055] Reference Figure 7The data acquisition module collects data based on an illumination level of 50 lux and the absence of personnel near the building facade. The control command generation unit calculates the current light intensity and the relative position of the driven rack to the initial position using a preset data processing method. It determines that the current environment is a low-light environment with no user activity and simulates the most appropriate adjustment method through an algorithm, which is then transmitted to the deformation control module.

[0056] After receiving the control command, the deformation control module will control the servo motors in each independent motion execution module to operate. Ultimately, the servo motors of A1-A4, C1-C4, and E1-E4 will control the corresponding driven racks to move forward 0.25m along the X-axis relative to the initial state, while the servo motors of B1-B4, D1-D4, and F1-F4 will control the corresponding driven racks to remain in the initial state. Following the same principle as the previous step, the X-coordinate of the junction point of the lightweight telescopic aluminum strips fixed at the end of the driven racks within the lightweight aluminum ring changes. The varying degrees of stretching of the lightweight telescopic aluminum strips form a special curve, pushing the flexible membrane to deform in different areas. This drives the flexible membrane to produce a large wave-like shape on the entire facade. The stretching depth of the flexible membrane in each area is approximately 0.22m, and the membrane surface tilt angle is 35°. At this time, indoor users can clearly perceive the supplemental light from the outside of the building.

[0057] After the deformation control module finishes operating, it continues to receive measurement data transmitted by the data acquisition module. The processed data is then sent to the control command generation unit to determine the next adjustment movement.

[0058] Reference Figure 8 The data acquisition module inside the building collects data based on an illumination level of 600 lux, and the distance between the two users and the motion execution modules in the second and fifth columns is 0.65m. The control command generation unit, based on the current acquired data and the relative position of the driven rack to its initial position, calculates using a preset data processing method to determine if the current environment is one of strong light and user activity. It then simulates the most appropriate adjustment method using an algorithm and transmits it to the deformation control module.

[0059] After receiving the control command, the deformation control module will control the servo motors in each independent motion execution module to operate. This will cause the servo motors B1, B4, E1, and E4 to move their corresponding driven racks forward 0.25m along the X-axis relative to their initial state; the servo motors A1, A4, B2, B3, C1, C4, D1, D4, E2, E3, F1, and F4 to move their corresponding driven racks forward 0.15m along the X-axis relative to their initial state; and the servo motors A2, A3, C2, C3, D2, D3, F2, and F3 to keep their corresponding driven racks in their initial state. Following the same principle as the previous step, from... The X-coordinate of the junction point of the lightweight telescopic aluminum strip, which is fixed at the end of the moving rack and connected to the lightweight aluminum ring, changes. The varying degrees of stretching of the lightweight telescopic aluminum strip form a special curve, causing the flexible membrane to deform in different areas. This drives the flexible membrane to produce a large wave-like shape across the entire facade. In areas close to users, the stretching depth of the flexible membrane is approximately 0.20m, with a membrane surface tilt angle of 30°. At this point, indoor users can clearly perceive the outdoor light source and have a clearer outdoor view. In areas further away from users, the stretching depth is approximately 0.10m, with a membrane surface tilt angle of 12°. At this point, indoor users have a weaker outdoor view, and less of the strong indoor light is exposed to the outside. After the deformation control module finishes operating, it continues to receive measurement data transmitted from the data acquisition module. The processed data then enters the control command generation unit to determine the next adjustment movement.
