Module Connector Locking Sequence for Leak-Tight Bulk Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bulk material handling systems face challenges in securely docking and undocking container modules without fluid leakage or contamination of the surroundings, particularly for powders and hazardous materials, where the movement of bulk material into the environment during docking/undocking is a concern.
Innovation Solution
A docking device with a blocking assembly and actuating mechanism that ensures the valve body can only be opened after correct locking, featuring a failsafe design where the actuating pin moves downward to lock and then open the valve during docking, and upward to close and release the lock during undocking, preventing fluid flow unless the locking position is achieved, and utilizing sealing surfaces and seal elements to minimize contamination.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the valve body is opened during docking/undocking operations, then fluid flow is enabled, but bulk material may leak into the surroundings
Solution Approach 1:
The blocking means is actuated before the valve body to ensure the docking segments are securely locked together before fluid flow begins. This preliminary locking action prevents bulk material leakage by establishing mechanical connection integrity before opening the valve, resolving the contradiction between enabling fluid flow and preventing leakage.
Solution Approach 2:
The blocking means acts as an intermediary mechanism between the docking segments and the valve body. It mediates the docking process by providing a secure mechanical lock that must be established before the valve can be opened, thereby preventing bulk material from escaping into the surroundings during the docking/undocking operation.
2Reliability
If the docking segments are securely locked together, then leak-tight connection is achieved, but the valve body cannot be opened
Solution Approach 1:
The blocking means is actuated in advance to establish secure locking of the docking segments before the valve body is opened. This preliminary action ensures connection security is achieved first, then enables fluid flow capability in a controlled sequence, resolving the contradiction between reliable connection and productivity.
Solution Approach 2:
The actuating assembly provides dynamic control over the docking process by enabling sequential actuation of the blocking means and valve body. This dynamic mechanism allows the system to transition from a locked state (high reliability) to an open state (high productivity) in a controlled manner, resolving the contradiction between connection security and fluid flow capability.
3Productivity
If the actuating assembly allows valve opening during undocking, then fluid flow is enabled, but bulk material may escape into the environment
Solution Approach 1:
The system inverts the conventional sequence by requiring the blocking means to be actuated before the valve body can be opened, even during undocking operations. This inverted logic ensures that fluid flow capability is only enabled when the docking segments are securely locked, preventing bulk material contamination while maintaining productivity when properly configured.
Solution Approach 2:
The blocking means serves as an intermediary that controls and mediates the valve opening process. It ensures that bulk material cannot escape into the environment by requiring secure locking of the docking segments as a prerequisite for enabling fluid flow, thereby eliminating contamination while preserving productivity.

AI summary
A docking device for mechanically connecting an upper and a lower container module of a multipart container. The docking device includes an upper docking segment which is fastenable on an opening of the upper container module, and a lower docking segment which is fastenable on an opening of the lower container module. Fluid is configured to move from the upper container module into the lower container module. An upper docking region of an upper channel section and/or an upper docking segment and a lower docking region of a lower channel section and/or the lower docking segment can be arranged in such a way that the fluid flows through an externally leak-tight channel in an open valve body position. An actuating assembly is arranged in the upper channel section and/or in the lower channel section.
