Guard Door Regional Control for Safer Warehouse Tool Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In warehousing systems, the need for users to enter for inspection or other tasks requires stopping all goods-carrying tools, leading to low efficiency and hardware loss due to frequent starting and stopping of these tools.
Innovation Solution
A method and apparatus for controlling a warehousing system that determines the state of goods-carrying tools in specific regions, allowing only those in non-operating states to be accessed by users, while keeping tools in other regions operational, thereby improving efficiency and reducing hardware loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If all goods-carrying tools are stopped when a user enters the warehousing system, then user safety is ensured, but warehousing efficiency deteriorates
Solution Approach 1:
The warehousing system is divided into multiple regions with guard doors, and goods-carrying tools are segmented into different operational zones. When a user enters through a specific guard door, only the goods-carrying tool in that specific region is stopped, while tools in other regions continue operating. This regional segmentation resolves the contradiction by limiting the safety measure to only the necessary area rather than stopping all tools system-wide.
Solution Approach 2:
The safety control is applied locally to specific regions rather than uniformly across the entire system. Each guard door corresponds to a specific target region, and the stopping action is applied only to goods-carrying tools within that target region. This local quality approach ensures user safety in the entered region while maintaining productivity in other regions.
2Reliability
If all goods-carrying tools are stopped when a user enters the warehousing system, then user safety is ensured, but hardware loss of goods-carrying tools increases due to frequent starting and stopping
Solution Approach 1:
The system segments the stopping action to affect only one goods-carrying tool in the target region rather than stopping all tools. This reduces the frequency of starting and stopping events for individual tools, thereby reducing hardware wear and loss while still ensuring safety in the entered region.
Solution Approach 2:
The safety measure is applied locally to a specific region and its corresponding goods-carrying tool, rather than system-wide. This localized approach minimizes the impact on overall tool utilization and reduces the cumulative hardware loss from repeated stopping and starting of multiple tools.
3Reliability
If goods-carrying tools are stopped in the target region when a user enters, then safety of the target region is ensured, but operational tools in other regions are unnecessarily halted
Solution Approach 1:
The system divides the warehousing area into multiple regions, each with its own guard door and corresponding goods-carrying tool. When a user enters through a specific guard door, the control system identifies the target region and stops only the goods-carrying tool in that region. Tools in other regions continue their operations uninterrupted, maintaining overall productivity while ensuring local safety.
Solution Approach 2:
The safety control mechanism applies different states to different regions: the target region enters a safety mode with the goods-carrying tool stopped, while non-target regions maintain normal operational mode. This local quality differentiation ensures that safety measures are applied only where needed, preserving operational efficiency in other areas.

AI summary
The present disclosure provides a method and apparatus for controlling a warehousing system, a guard door, and a warehousing system. The method includes: obtaining a door-opening-request signal of a guard door, and determining a target region corresponding to the guard door; determining that a state of a first goods-carrying tool in the target region is a non-operating state; and controlling a state of the guard door to be an open state. The safety of the target region where a user enters is ensured. In addition, the state of the goods-carrying tool in the target region corresponding to the guard door is controlled to be a non-operating state and a goods-carrying tool in a non-target region is kept to operate normally, and therefore, when compared with the related art of stopping all goods-carrying tools, the warehousing efficiency is improved and a hardware loss caused to the goods-carrying tool due to repeated starting and stopping is reduced.
