Description

Technical Field

[0001] This invention relates to the field of logistics packaging, and more particularly to a fragile goods logistics packaging kit with a breakage warning function. Background Technology

[0002] Currently, the transportation of high-value, fragile items (such as precision instruments, works of art, and high-end industrial components) mainly relies on enhanced passive protective packaging solutions, such as customized thickened foam, solid wood reinforced boxes, or mechanical suspension shock absorption systems. Although these solutions can provide a certain degree of physical cushioning, they are essentially still black box transportation. Throughout the entire logistics process, the actual stress, posture changes, impact vibration spectrum, and other key physical parameters of the items inside the packaging are completely unknown.

[0003] This lack of status information leads to serious management and liability dilemmas: when the shipment ends and the damaged goods are discovered upon opening the package, it is impossible to trace the specific time point when the damage occurred (such as during loading and unloading in the warehouse, long-distance transportation, or the final sorting stage) and the direct cause (whether it was dumping, violent impact, or resonance fatigue). This uncertainty often leads to long-term liability disputes between the shipper, carrier, insurance company, and consignee, and the claims process is lengthy and difficult.

[0004] Therefore, existing technologies have significant shortcomings in the logistics of high-value, fragile goods: on the one hand, they cannot accurately perceive and digitally record the true physical state of assets in transit in real time and from multiple dimensions; on the other hand, they are even less able to provide proactive early warnings in the early stages of risk accumulation, failing to provide logistics managers with a basis for timely intervention. This leaves the entire transportation process in an uncontrollable risk blind spot, making it difficult to meet the high standards of transparency, traceability, and proactive risk management required by modern supply chains. Summary of the Invention

[0005] To address the aforementioned technical problems, this invention aims to provide a fragile goods logistics packaging kit with a damage warning function, thereby resolving the technical issues that existing passive packaging cannot monitor, warn, and record the transportation environment in real time, leading to unclear liability for damage and uncontrollable risks.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A fragile goods logistics packaging kit with a breakage warning function includes a composite cushioning chamber, a main control circuit chamber, and a lid. The composite cushioning chamber includes a flexible inner liner, an inflatable support pad, and a box body from the inside out. The inflatable support pad is symmetrically arranged between the flexible inner liner and the inner side of the box body. A hollow columnar connector is fixedly connected to the center of the bottom surface inside the box body. An item carrying platform is fixedly connected to the top of the hollow columnar connector. A sensor sealing chamber is suspended in the internal cavity of the hollow columnar connector.

[0007] An inertial measurement unit and a broadband vibration sensor are rigidly installed inside the sensor sealed chamber. The inertial measurement unit is used to measure the motion posture and impact acceleration of the item carrying platform. The broadband vibration sensor is used to capture vibration signals during transportation. A thin-film pressure sensor array is provided on the bearing surface of the item carrying platform to monitor the pressure distribution at the bottom of the protected item.

[0008] The main control circuit compartment is equipped with a data processing and communication module and a power supply module. The power supply module is electrically connected to the data processing and communication module, the inertial measurement unit, the broadband vibration sensor, and the thin-film pressure sensor array, and provides them with operating power. The data processing and communication module is used to receive and process the data transmitted by the inertial measurement unit, the broadband vibration sensor, and the thin-film pressure sensor array.

[0009] The sensor sealed chamber is connected to the hollow columnar connector through a shock-absorbing structure. The surface of the item carrying platform has perforations for threading straps. The outer surface of the inflatable support pad has an inflation nozzle and is fixed to the inner side of the box through a detachable connector.

[0010] Furthermore, the shock-absorbing structure is a silicone shock-absorbing pad fitted onto the outer wall of the sensor sealed chamber. The sensor sealed chamber is interference-fitted with the hollow cylindrical connector through the shock-absorbing pad and fixed to the hollow cylindrical connector by bolts to achieve suspended installation. This not only ensures the motion coupling between the sensor and the protected object to achieve high-fidelity measurement, but also isolates the sensor from external vibration interference, thereby improving measurement accuracy.

[0011] Furthermore, the flexible inner lining layer is made of polyurethane slow-rebound foam and is filled between the protected item and the inflatable support pad to disperse local stress and prevent the protected item from being damaged due to excessive local force. The enclosure is assembled and welded from aluminum alloy profiles, which has the characteristics of high strength and impact resistance. Its wall surface has wiring holes and an integrated radio frequency transparent skylight. The wiring holes are used for the wiring between the sensor and the data processing and communication module, and the radio frequency transparent skylight is used to ensure the normal transmission of wireless communication signals and avoid the shielding of signals by the metal material of the enclosure.

[0012] Furthermore, the data processing and communication module incorporates a risk assessment model, which includes an impact spectrum analysis model, an attitude safety domain model, and a pressure distribution equilibrium model. The data processing and communication module also includes a storage unit and a wireless communication unit. The storage unit is used to record the raw data or feature data of all sensors and form a logistics record. The wireless communication unit includes a low-power wide-area network communication module (such as an NB-IoT module) that supports remote transmission and a Bluetooth communication module that supports near-field interaction, which respectively realize remote early warning information reporting and near-field data reading.

[0013] Furthermore, the data processing and communication module performs frequency domain analysis on the vibration signals collected by the broadband vibration sensor using the impact spectrum analysis model, extracts the vibration energy spectral density, and compares it with a preset threshold to assess resonance risk. The data processing and communication module also compares the three-dimensional attitude angle and angular velocity data collected by the inertial measurement unit with a preset safe tilt angle and angular velocity envelope using the attitude safety domain model to determine the risk of tipping or instability. Finally, the data processing and communication module analyzes the pressure data collected by the thin-film pressure sensor array using the pressure distribution uniformity model, calculates the variance or range of the pressure distribution, and compares it with a preset threshold to identify local stress concentration risks. Through multi-model collaborative analysis, a comprehensive and accurate identification of risks in the transportation of fragile goods is achieved.

[0014] Furthermore, the power supply module adopts a modular battery compartment, which contains at least two lithium iron phosphate batteries connected in series. These batteries have the characteristics of large capacity, long life, and high safety. The modular design also facilitates replacement and maintenance. The bearing surface of the item carrying platform is also equipped with an anti-slip silicone cushioning pad. The thin-film pressure sensor array is laminated and encapsulated between the anti-slip silicone cushioning pad and the item carrying platform. The anti-slip silicone cushioning pad can prevent the protected item from sliding and also protect the thin-film pressure sensor array.

[0015] The technical solution provided in this disclosure has the following advantages compared with the prior art: 1. Through an innovative hollow cylindrical connector structure, the sensor is coupled to the protected item and combined with a multi-dimensional sensor network to achieve accurate and digital perception and full-process recording of the real physical state (impact, vibration, posture, and force) of the item inside the packaging. This completely breaks down the information barrier of traditional black box transportation. Furthermore, through various sensors, it can identify risks such as resonance, tipping, and local stress concentration in real time during transportation, providing logistics managers with a basis for timely intervention and decision-making, achieving proactive risk management, and effectively reducing the breakage rate of fragile items.

[0016] 2. The kit adopts a robust, reusable modular design, combined with intelligent monitoring and leasing service models, which can spread costs over multiple cycles of use, providing a cost-effective proactive risk management solution for the high-end logistics market and demonstrating significant commercial viability.

[0017] 3. Complete logistics data provides an objective and reliable electronic chain of evidence for potential cargo damage disputes after transportation, which can clearly identify the damaged links and responsible parties, and simplify the claims process. Attached Figure Description

Detailed Implementation

[0022] To better understand the above-mentioned objectives, features, and advantages of this disclosure, the solutions disclosed herein will be further described below. It should be noted that, unless otherwise specified, the embodiments and features described herein can be combined with each other.

[0023] Numerous specific details are set forth in the following description in order to provide a full understanding of this disclosure, but this disclosure may also be implemented in other ways different from those described herein; obviously, the embodiments in the specification are only some, and not all, of the embodiments of this disclosure.

[0024] This invention provides a fragile goods logistics packaging kit with a breakage warning function, which is described below in conjunction with the attached... Figures 1 to 3 The specific embodiments of the present invention will be described in detail below.

[0025] like Figures 1 to 3As shown, the fragile goods logistics packaging kit with damage warning function in this embodiment has an overall rectangular box structure. Its outermost layer is the box 3, which provides the main load-bearing frame. The top of the box 3 is covered with a box cover 6. At the center of the box 3, a material carrying platform 8 is rigidly connected by a hollow columnar connector 7. After the protected item is placed on the material carrying platform 8, the gaps around it are filled with a flexible inner lining layer and pressed and fixed by inflatable support pads 4 symmetrically arranged on the four inner sides of the box 3. This makes the protected item, the material carrying platform 8 and the hollow columnar connector 7 approximately a moving whole, ensuring that the sensor measurement data can accurately reflect the state of the protected item. The hollow columnar connector 7 has a sensor sealed chamber 12 suspended inside, which is equipped with the core measurement sensor. The main control circuit chamber 2 and the modular battery chamber are located on both sides of the bottom of the box 3, respectively realizing data processing, communication warning and power supply functions.

[0026] The enclosure 3, serving as a rigid protective frame, is assembled and welded from aluminum alloy profiles using angle bracket connectors. It features high strength, impact resistance, and corrosion resistance, effectively resisting external impacts during transportation. A threaded blind hole is pre-embedded at the center of the bottom inner side of the enclosure 3, used to achieve a rigid connection with the hollow columnar connector 7 via bolts. The connection is secure and easy to disassemble and maintain. The walls of the enclosure 3 have wiring holes and an integrated radio frequency transparent skylight. The wiring holes are used for the routing of lines between the sensor and the data processing and communication modules. The radio frequency transparent skylight is made of polypropylene plastic, ensuring the normal transmission of wireless communication signals and avoiding signal shielding interference from the metal material of the enclosure 3.

[0027] Four inflatable support pads 4 serve as lateral protection and limiting mechanisms. They are fixed to the center of the four inner sides of the housing 3 via Velcro (detachable connectors) for easy installation, disassembly, and replacement. Each inflatable support pad 4 is made of high-strength TPU film material through heat sealing, providing good sealing performance and strong pressure resistance. Its outer surface is equipped with an inflation nozzle 5 that opens towards the top of the housing 3 for easy inflation and deflation. After inflation, it can laterally compress the flexible inner lining layer, allowing the flexible inner lining layer to adaptively fill the gap between the protected item and the inflatable support pad 4. The flexible inner lining layer is made of polyurethane slow rebound sponge, which has good cushioning and shock absorption performance, can disperse local stress on the surface of the protected item, and prevent the item from being damaged due to compression.

[0028] The hollow cylindrical connector 7 is an aluminum alloy round tube with a flange with a through hole welded to its bottom end. It is rigidly connected to the threaded blind hole at the bottom of the box 3 by bolts, resulting in high connection strength. A circular carbon fiber plate serving as an item carrying platform 8 is coaxially welded to the top of the connector 7. The carbon fiber plate is lightweight and high-strength, effectively supporting the weight of the protected item without increasing the overall weight of the kit. A layer of anti-slip silicone cushioning pad 9 is glued to the surface of the item carrying platform 8. The anti-slip silicone cushioning pad 9 can prevent the protected item from sliding during transportation and also play an auxiliary cushioning role. The item carrying platform 8 has evenly spaced perforations near the edge for threading straps, which facilitates the secure fixing of the protected item to the item carrying platform 8 using the double cross binding method, increasing the fixing strength and preventing the item from shaking.

[0029] The sensor sealing chamber 12 is a cylindrical 304 stainless steel sealed shell with good sealing and anti-interference performance, which can protect the internal sensor from dust and moisture. Its outer wall is covered with silicone shock-absorbing pads 11. By pressing the sensor sealing chamber 12 with silicone shock-absorbing pads 11 into the top opening of the connector 7, the sensor is suspended at the geometric center position inside the connector 7 by the interference fit between the silicone shock-absorbing pads 11 and the inner wall of the hollow cylindrical connector 7. The sensor sealing chamber 12 is then fixed to the hollow cylindrical connector 7 by bolts. The silicone shock-absorbing pads 11 can isolate the interference of external vibration on the sensor, while ensuring the synchronization of the movement of the sensor and the object carrying platform 8, so as to achieve high-fidelity measurement.

[0030] Inside the sensor sealed chamber 12, the inertial measurement unit 13 is rigidly connected to the center of the chamber by screws. It is used to measure the three-dimensional attitude angle, angular velocity and linear impact acceleration of the item carrying platform 8, and to capture the attitude changes and impact conditions of the item in real time. The broadband vibration sensor 14 is rigidly connected to the sensor sealed chamber 12 by screws and is installed in parallel with the inertial measurement unit 13. It is used to capture medium and high frequency vibration signals during transportation and to provide data support for resonance risk assessment. The thin film pressure sensor array 10 is composed of multiple FSR sensor units integrated on a flexible printed circuit board. The circuit board is laminated and encapsulated between the item carrying platform 8 and the anti-slip silicone buffer pad 9 above it. It is used to monitor the pressure distribution at the bottom of the protected item and identify the risk of local stress concentration. Each sensor is connected to the data processing and communication module by wiring. The wiring passes through the wiring holes on the hollow columnar connector 7 and the wall of the box 3, which is neatly arranged and does not affect the normal use of the kit.

[0031] The main control circuit compartment 2 is an aluminum alloy shielded box fixed inside the bottom wall of the housing 3, which can effectively shield external electromagnetic interference and protect the normal operation of the internal circuit. It contains a data processing and communication module, which includes a microcontroller and a large-capacity memory. The microcontroller is used to run risk assessment algorithms, process data collected by sensors, and control the operation of communication and alarm units. The large-capacity memory is used to continuously record the raw data or feature data of all sensors to form logistics records for easy data traceability. The dual-mode communication antenna is integrated on a flexible circuit board and is attached to the inside of the radio frequency transparent skylight on the inner side wall of the housing 3. The dual-mode communication antenna includes a long-range low-power wide area network communication unit (NB-IoT communication module in this embodiment) and a short-range high-speed interaction unit (Bluetooth communication module in this embodiment), which respectively realizes remote early warning information reporting and short-range data reading. The main control circuit compartment 2 is also equipped with a local sound and light alarm unit, which can trigger sound and light alarms when a risk event is detected to remind on-site personnel to deal with it in time.

[0032] The power supply module adopts a modular battery compartment, which is fixed inside the bottom wall of the housing 3 and arranged in parallel with the main control circuit compartment 2. The battery compartment holds two lithium iron phosphate batteries connected in series, providing stable power for the entire system. Lithium iron phosphate batteries have large capacity, long cycle life, and high safety, which can meet the needs of long-term transportation monitoring. The modular design facilitates battery replacement and maintenance. When the battery is depleted, the battery compartment can be quickly replaced without affecting the normal use of the kit. The power supply module is electrically connected to the data processing and communication module, inertial measurement unit 13, wideband vibration sensor 14, thin film pressure sensor array 10, and audible and visual alarm unit through the wiring, providing suitable operating voltage for each component.

[0033] The workflow is as follows: Place the fragile item to be protected on the anti-slip silicone cushioning pad 9 of the item carrying platform 8, adjust the item's position to the center, take two nylon webbing straps, the first webbing strap passes through a set of diagonal perforations on the item carrying platform 8 from bottom to top, crosses around the protected item, and then passes back to the bottom through another set of diagonal perforations and locks it, the second webbing strap is tied in the same way along the vertical direction, and the item is firmly fixed by the double cross binding method, the flexible inner lining layer made of polyurethane slow rebound sponge is filled between the protected item and the four inflatable support pads 4, and each inflatable support pad 4 is inflated through the air nozzle 5 until the support pad 4 presses the flexible inner lining layer, so that the item is stably clamped, close the box lid 6 and lock it with the buckle, start the whole system, the power supply module starts to supply power to each component, and the system enters the standby state.

[0034] After the system starts, the inertial measurement unit 13, the broadband vibration sensor 14, and the thin-film pressure sensor array 10 continuously collect data at a frequency of 10Hz. The inertial measurement unit 13 collects the three-dimensional attitude angles (pitch angle, roll angle, yaw angle), angular velocity, and linear impact acceleration data of the object carrying platform 8 in real time. The broadband vibration sensor 14 collects the vibration signals during transportation in real time (frequency range 10Hz-1000Hz). The thin-film pressure sensor array 10 collects the pressure distribution data at the bottom of the protected object in real time. Each sensor transmits the raw data collected to the data processing and communication module in real time through the line.

[0035] The microcontroller in the data processing and communication module processes the collected data in real time and identifies risks using a built-in risk assessment model, specifically including: The microcontroller performs a Fast Fourier Transform (FFT) on the vibration signal acquired by the broadband vibration sensor 14 using an impact spectrum analysis model, converting the time-domain signal into a frequency-domain signal, extracting the vibration energy spectral density at different frequencies, and preset a resonance risk threshold (e.g., 5 × 10⁻⁶). - If the vibration energy spectral density at a certain frequency exceeds the threshold and the duration is ≥5s, it is judged as a resonance risk. At this time, the protected item may suffer fatigue damage due to resonance. The microcontroller analyzes the three-dimensional attitude angle data collected by the inertial measurement unit 13 through the attitude safety domain model and presets a safe tilt angle (e.g., 30°). If the attitude tilt angle (pitch angle or roll angle) exceeds the safe tilt angle and the duration is ≥2s, it is judged as a risk of tipping / instability. At this time, the item may be damaged by collision due to tipping. The microcontroller processes the pressure data of each unit collected by the thin-film pressure sensor array 10 through the pressure distribution uniformity model and calculates the variance of the pressure distribution (the preset threshold is 100 kPa²). If the variance exceeds the threshold, it indicates that the item is subject to local stress concentration due to loose fixation or posture deviation, which is judged as a risk of local stress concentration. At this time, the item may be damaged due to excessive force in some areas. In this embodiment, the preset thresholds can be individually adjusted according to the material, weight, and fragility level of the protected precision instrument, and the adjusted thresholds are remotely written into the memory of the data processing and communication module via the Bluetooth communication module.

[0036] If any risk is identified, the data processing and communication module immediately alerts on-site personnel (such as logistics sorters and drivers) to check the status of the equipment and take intervention measures (such as adjusting the transportation posture and slowing down). At the same time, the data processing and communication module reports the risk information (including risk type, occurrence time, and real-time data) to the cloud management platform through the NB-IoT communication module. Logistics managers can view the risk situation in real time and remotely dispatch interventions through the cloud platform. During this process, the storage unit continuously records the raw data, data processing results, and risk assessment results of all sensors, forming a logistics process data record. The recording interval is consistent with the collection frequency to ensure the integrity and traceability of the data.

[0037] After transportation is completed, the consignee and the carrier jointly open the box for inspection. If no damage occurs, the logistics process data records in the storage unit can be read through the Bluetooth communication module of the mobile phone Bluetooth connection kit to confirm that there are no abnormal risks in the transportation process. If damage occurs, the relevant parties (shipper, carrier, insurance company) can be authorized to retrieve the complete data records in the storage unit. Through data analysis, the specific time node of the damage (such as impact on a certain transportation section, spillage in the sorting process) and direct cause can be determined, the damaged link and responsible party can be clearly defined, and the claims process can be simplified.
