Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a physical barrier is disposed between the operator and the logistics transporting device to provide safety protection, then operator safety is improved, but the logistics transporting device is prone to losing control and colliding with the barrier
Solution Approach 1:
The system performs preliminary actions by detecting the logistics transporting device's approach in advance through detectors positioned at the barrier base. The controller receives detection signals and activates the braking mechanism before collision occurs, preventing the harmful effect while maintaining the protective barrier structure.
Solution Approach 2:
The system establishes a feedback loop where detectors continuously monitor the logistics transporting device's position and send signals to the controller. When the device approaches the barrier, the controller receives feedback and automatically activates the braking mechanism, creating a closed-loop safety system that responds to real-time conditions.
2Ease of operation
If the operation window is positioned above the tote to allow operator interaction, then picking and placing operations are enabled, but the logistics transporting device may still collide with the barrier at normal operating speeds
Solution Approach 1:
The braking mechanism acts as an intermediary between the logistics transporting device and the barrier base. When the detector identifies approaching equipment, the controller activates the brake to intervene and stop the device before collision occurs, allowing the operation window to remain in its optimal position for operator interaction without compromising safety.

AI summary
The present disclosure provides a workstation and a warehousing system, and relates to the field of warehousing and logistics technologies. The workstation includes a workstation body, a barrier base, and a monitoring assembly. The barrier base is disposed in the workstation body to divide the workstation body into a traveling area and an operation area, the barrier base is provided with an operation window, and the operation window is located above a tote on a logistics transporting device. The monitoring assembly includes a first detectorand a controller, the first detector is disposed on a detection section in the traveling area, and the detection section corresponds to the operation window. The first detector is configured to detect identity information of the logistics transporting device entering the detection section, and the controller is configured to control the logistics transporting device to brake when a speed of the logistics transporting device entering the detection section is greater than or equal to a first preset speed. When the logistics transporting device exceeds a speed limit in the detection section, the controller may control the logistics transporting device to brake, and a height of the operation window is used for blocking, thereby ensuring safety of the workstation.
