Is it feasible to convert a traditional hardware warehouse into smart unattended warehouse facility?

Many large manufacturing enterprises maintain a dedicated small warehouse designated as a hardware storage facility, where screws, nuts, loose drill bits, and various commonly used consumables are centrally stored—spanning over 200 different material categories. This warehouse is staffed with full-time warehouse personnel on fixed shifts, and material requisitioning is permitted only during the day shift hours. However, during night-shift production or when unexpected equipment repairs occur at night, if the warehouse team needs to request drill bits, fasteners, or maintenance consumables but no personnel is on duty, the materials cannot be obtained promptly. This situation directly hinders the efficiency of both nighttime production operations and the response to equipment failures.

The hardware warehouse serves as a critical supply hub for factory production and equipment maintenance and operation; although it primarily stores small, discrete items, its operations directly impact the continuity of assembly production and the timeliness of equipment emergency repairs. During nighttime production line debugging or when equipment malfunctions occur, if the necessary screws, nuts, drill bits, or consumables cannot be immediately obtained, the team must wait for the day-shift warehouse keeper to arrive. Even during daytime shifts, this small hardware warehouse still faces multiple management challenges.

The warehouse stores over 200 different types of materials, ranging from large quantities of standard fasteners to small batches of drill bits and specialized consumables requested on demand; the material specifications are highly diverse, and many components closely resemble each other in appearance. The storage height of materials is determined based on the personal experience of the on-site warehouse keeper, and new employees take longer to become proficient in this role. When handling urgent production orders, material requisitioners must wait for the warehouse keeper to locate, verify, and dispense the materials; during peak periods, queues may form for material requisitioning. Should a warehouse keeper take leave or be reassigned to another position, there is a risk of discontinuities in the material storage locations.

The inbound and outbound inventory recording process is entirely manual. For discrete components such as screws and nuts, it is difficult to count each item individually; instead, these transactions are handled through manual counting and handwritten documentation. In practice, it is common for materials to be issued before the corresponding replenishment orders are submitted. Over time, this can lead to discrepancies between the system records and the actual physical inventory—often resulting in situations where the system shows that a material is available, but the warehouse cannot locate it. During the monthly physical inventory count, verifying over 200 different categories of discrete items requires significant manpower for one-by-one comparison; this constitutes a heavy workload, and once any discrepancy arises, tracing its root cause becomes extremely challenging.

Furthermore, the existing dedicated personnel management system lacked proper permission-leveling mechanisms; there were no constraints on material requisitioning by personnel in different roles; and after tools such as drill bits or consumables were issued, there was no comprehensive circulation record maintained. As a result, it was difficult to identify the specific person responsible for any abnormal material loss or waste.

Many companies have attempted to improve their operations by hiring additional night-shift warehouse staff, optimizing label tracking systems, or enhancing employee training. However, adding night-shift personnel directly drives up labor costs; relying solely on policies and human resource management often fails to fully address long-standing pain points such as slow material retrieval, accounting errors, and cumbersome inventory counting processes. Converting existing small hardware storage rooms into unmanned warehouses has become a popular option for many manufacturing enterprises.

Designed for the renovation of existing small hardware storage areas within large manufacturing facilities, this unmanned warehouse solution is compatible with over 200 categories of materials—including screws, nuts, loose-cutting tools, and commonly used consumables—and enables modular deployment directly within existing warehouse spaces, delivering a 24/7 operational unmanned warehousing solution. The entire system employs a modular intelligent shelving configuration, allowing for flexible allocation of storage locations based on the available space in the original rooms—ensuring that each item occupies a dedicated spot. Screws, nuts, cutting tools, and various consumables are stored in designated zones and at fixed locations, effectively meeting both large-volume bulk material storage and small-batch spare part storage requirements while maximizing the utilization of existing warehouse space without necessitating extensive structural modifications.

After the system upgrade, the warehouse no longer requires a custodian to be on-site at all times. Production and equipment maintenance personnel, whether working during day or night shifts, can now access the smart unmanned warehouseand retrieve materials independently after completing identity verification. The system integrates with work orders and provides corresponding light guidance for specific storage locations; upon receiving this guidance, material-retrieval personnel can quickly locate the required items without having to wait for the warehouse staff to pick or dispatch the materials – effectively addressing the pain point of lacking available materials during nighttime emergency repairs or night-shift production operations.

Each storage location is equipped with a high-precision weighing sensor unit; for discrete items such as screws and nuts, the system automatically calculates the quantity of material based on weight variations, and automatically updates inventory levels upon material withdrawal or replenishment – eliminating the need for manual documentation or manual entry into ledger records. For every material retrieval or placement operation, the system automatically logs comprehensive records—including the operator's identity, operation time, material model, and quantity—ensuring full traceability throughout the entire material flow process.

For over 200 different categories of materials, managers can set individual safety stock thresholds for each material in the backend system; when the material inventory falls below this threshold, a replenishment reminder is automatically sent out, notifying warehouse staff to restock the materials in advance and prevent supply disruptions.

在大型制造企业运营的传统硬件仓库中，主要挑战不仅在于物料种类繁多，还在于专职人员轮班所带来的时间相关障碍：这些仓库通常仅在白天开放，这阻碍了夜间紧急维修和夜间物料领用；此外，由于人工管理超过200种不同物料类别所引发的一系列问题——如拣货速度慢、账目频繁出错以及盘点劳动强度大——进一步加剧了这一状况。

Human-operated storage systems drive up labor costs, while simply optimizing management systems cannot overcome the temporal limitations imposed by manual staffing. By converting existing warehouses into unmanned facilities without altering the physical infrastructure of the premises, we transform the traditional warehouse model—which relies on the presence of warehouse staff—into a digital self-service warehousing system available 24/7.

This solution eliminates time constraints on material requisitioning, addressing the challenges associated with retrieving materials during nighttime emergency repairs or night-shift production; it also frees warehouse personnel from repetitive tasks such as material picking, manual bookkeeping, and labor-intensive inventory counting, enabling them to focus on high-value activities like material planning and inventory optimization. It ensures that inventory data for over 200 different material categories remains accurate and under tight control, providing a reliable supply chain support for the factory's round-the-clock production and operations.
