Divided Base Ring Element for Secure Lashing Attachment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lashing or attaching devices are limited in their ability to securely attach strips or ropes and can only transmit restricted lateral forces due to their open structure, making them unsuitable for applications requiring high force transmission.
Innovation Solution
A ring element with a base divided by an attachment channel that leads into the ring opening, allowing for easy insertion of loops and secure closure, and featuring form-fit elements and a rotatable installation mechanism to enhance force transmission and compatibility with high-strength textile materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If connection elements such as shackles, snap hooks or ring loops are used to attach chain links or loops, then attachment is possible, but the structure becomes complex and lateral force transmission is restricted
Solution Approach 1:
The patent merges the attachment channel and the base into a single integrated component. The attachment channel is formed as an integral part of the base, eliminating the need for separate connection elements like shackles or snap hooks. This unified structure allows direct insertion and attachment of loads while maintaining structural simplicity and enabling effective lateral force transmission through the monolithic design.
2Ease of operation
If an open structure like fork crown is used, then attachment is possible, but lateral force transmission is restricted
Solution Approach 1:
The base is segmented into two parts by the attachment channel, creating a divided base structure. This segmentation allows the attachment channel to be formed as a distinct feature within the base, enabling direct insertion of attachment elements while the surrounding base material provides structural support for lateral force transmission. The divided base maintains structural integrity while facilitating attachment operations.
3Force
If a divided base with attachment channel is used, then force transmission and attachment capability are improved, but manufacturing complexity increases
Solution Approach 1:
The attachment channel is formed as a pre-integrated feature during the base manufacturing process. By incorporating the attachment channel formation into the base fabrication step (through casting, molding, or machining operations), the divided base structure is created in a single manufacturing sequence. This preliminary integration of the attachment channel eliminates the need for separate assembly operations, reducing overall manufacturing complexity despite the enhanced force transmission capability.

AI summary
The invention relates to a ring element (1) for a lashing or attachment device (40), with a base (10) and with a ring section (2) that is closed in an opposite position to the base (10) and that forms a ring opening (4). In order to be able to attach in particular loop-shaped ropes or strips, but also attachment devices such as shackles, hanging elements, loop hooks, in a simpler way, the base (10) is divided according to the invention by an attachment channel that reaches into the ring opening (4). A closing element (42) that is formed in a way as to be insertable in the attachment channel (8) preferably fits flush with the base (10).
