Pivotable Receptacle for Container Suspension Wear Reduction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing container suspension devices for coupling containers to transporter set-down arms require frequent adjustments in chain length, leading to wear and increased production costs due to complex configurations and materials.
Innovation Solution
A container suspension device with a pivotable receptacle system formed by two parallel traverse plates and laterally protruding arms, allowing the chain to pass through the pivot axis, reducing wear and enabling easy length adjustment with a securing mechanism to prevent chain detachment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a continuous bolt is used to mount the receptacle, then the mounting is robust and secure, but the chain strand cannot be guided directly between the mounting components, requiring additional length and complicating the design
Solution Approach 1:
The continuous bolt is segmented into two separate arms that project laterally from the mounting bracket. These arms create a defined space between them through which the chain strand can be guided directly, eliminating the need for the chain to dip in front of or be guided over a continuous bolt. This segmentation resolves the contradiction by enabling direct chain guidance while maintaining mounting robustness through the arm-container bracket connection.
Solution Approach 2:
The mounting design transitions from a single-dimensional continuous bolt to a multi-dimensional structure with laterally projecting arms. This dimensional change creates a three-dimensional space between the arms that allows the chain strand to pass through in the longitudinal direction, simplifying chain guidance and reducing the overall mounting length in the direction of pull.
2Device complexity
If the chain strand is guided over a continuous bolt, then the mounting is simple, but the chain strand dips in front of the bolt increasing the required length and causing wear
Solution Approach 1:
By segmenting the continuous bolt into two separate laterally projecting arms, the invention creates a through-path for the chain strand. This allows the chain to be guided between the arms rather than over them, eliminating the dip in front of the mounting component and reducing the required chain strand length.
3Adaptability or versatility
If chain length adjustments are made frequently using traditional shortening elements, then the desired length can be achieved, but wear occurs on the shortening elements and production costs increase
Solution Approach 1:
The receptacle is made pivotable relative to the crossbeam, allowing dynamic adjustment of the chain strand length. The receptacle can be rotated to different angular positions around the pivot axis, enabling flexible chain length adaptation without requiring complex shortening elements with moving parts that are subject to wear. This dynamic pivoting mechanism maintains reliability while providing adaptability.
4Ease of manufacture
If the receptacle is fixed relative to the crossbeam, then the structure is simple and robust, but the chain length cannot be easily adjusted
Solution Approach 1:
The receptacle is designed with pivotable mounting relative to the crossbeam, introducing a single degree of freedom for rotation. This dynamic element allows easy chain length adjustment by rotating the receptacle to different angular positions, while the overall structure remains simple and robust with minimal moving parts. The pivotable connection is achieved through a straightforward hinge or pivot mechanism that maintains structural integrity.
