Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing multi-coupling systems for chemical plant containers face challenges in simplifying the coupling process, particularly due to imprecise positioning and alignment requirements, which can lead to cumbersome and inefficient handling of bulky and heavy containers during filling and emptying operations.
Innovation Solution
A holding frame with a mounting device and compensating devices that allow for adjustable positioning and angular alignment of the multi-coupling, including linear, rotational, and tilt compensation, enabling flexible and adaptable coupling without precise alignment, and incorporating a curved delivery hose design to prevent kinking and wear.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a multi-coupling system is used for filling and emptying chemical plant containers, then the coupling capability is improved, but the positioning and alignment precision requirements increase, making the operation more complex
Solution Approach 1:
The holding frame incorporates compensating devices with slot-guided arms that allow dynamic adjustment of the multi-coupling position and orientation. The slots enable the coupling to adapt to positional deviations through guided movement, transforming a static rigid structure into a dynamic system that self-adjusts during operation.
Solution Approach 2:
The system changes geometric parameters (position coordinates and angular orientation) of the multi-coupling relative to the container through the compensating mechanism. By allowing continuous variation of these parameters within the slot constraints, the system accommodates imprecise positioning while maintaining coupling functionality.
2Reliability
If precise alignment is required for coupling, then the coupling reliability is improved, but the handling time and operational complexity increase
Solution Approach 1:
The compensating device with slot-guided arms enables the system to self-align automatically. When the multi-coupling approaches the container, the slots guide the arms into the correct positional and angular configuration without requiring external alignment operations, thus maintaining reliability while reducing handling time.
Solution Approach 2:
The holding frame is pre-configured with compensating devices that are ready to accommodate any positional deviation before coupling occurs. The slot geometry is designed in advance to provide the necessary adjustment range, so when misalignment is detected, the system can immediately compensate without additional alignment steps.
3Stability of the object's composition
If the multi-coupling is rigidly fixed to the holding frame, then the structural stability is improved, but the ability to compensate for positional deviations is lost
Solution Approach 1:
The connection between the multi-coupling and holding frame is made dynamic through the slot-guided arm mechanism. The arms can pivot and slide within the slots, providing controlled degrees of freedom that maintain structural integrity during normal operation while enabling position compensation when needed.
Solution Approach 2:
The rigid connection is segmented into multiple components: the holding frame, the slot-guided arms, and the multi-coupling. This segmentation allows each component to perform its specific function - the frame provides stable support, the arms provide adaptive positioning, and the coupling ensures secure connection - resolving the contradiction between rigidity and flexibility.

AI summary
The invention relates to a retaining frame (12) for a multicoupling (14) for filling and/or draining a chemical plant container, comprising an mounting device (20) for fastening the retaining frame in a substantially stationary manner and at least one compensation device (32, 38, 42) that can be coupled indirectly or directly to the multicoupling for varying a position of the multicoupling relative to the mounting device in a vertical direction and/or in a horizontal direction and/or for varying an angular position of the multicoupling relative to the mounting device about a vertical and/or horizontal rotational axis. Simple coupling of a multicoupling is thus enabled.
