Retractable Axle Stub Lashing Strap Mounting Socket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing attachment or lashing points require high effort for heavy-duty connections, limit access for welding, and complicate painting and corrosion protection, making them difficult to assemble, disassemble, and maintain.
Innovation Solution
A retractable axle stub system in the lashing strap and fastening base allows for easy assembly and disassembly, separate painting and galvanizing, and protection from damage, with features like axial retraction, spring-loaded locking, and pivotable designs to reduce structural volume and enhance load capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a heavy-duty connection is made between the load and the attachment point using known methods (screwing and welding), then the connection strength is improved, but the assembly effort and complexity increase significantly
Solution Approach 1:
The attachment point is divided into separate components: a mounting base that can be fixed to the load, and a separate attachment strap with a retractable axle stub. This segmentation allows the mounting base to be securely fixed while the attachment strap can be easily connected and disconnected, reducing assembly complexity while maintaining connection strength.
Solution Approach 2:
The retractable axle stub is nested within the mounting base, allowing it to be stored inside the base when not in use. This nesting mechanism enables the attachment strap to be compact during storage while providing easy access when needed, simplifying the overall assembly process.
2Reliability
If the attachment point structure is made complete and accessible for welding, then the connection reliability is improved, but the access for welding and painting is limited
Solution Approach 1:
The mounting base is pre-fixed to the load structure before the attachment strap is connected. This preliminary action allows welding and painting operations to be performed on the mounting base while it is in its final position, ensuring connection reliability while maintaining ease of access for finishing operations.
3Strength
If the attachment point is made permanent and robust, then the load capacity is improved, but the ease of disassembly and repair is reduced
Solution Approach 1:
The attachment strap incorporates a retractable axle stub that can dynamically transition between extended and retracted positions. When extended, it provides secure attachment for full load capacity; when retracted, it allows easy disassembly for repair or replacement, combining robustness with maintainability.
Solution Approach 2:
The attachment strap is designed as a replaceable component that can be easily discarded and replaced without affecting the mounting base. The retractable axle stub mechanism allows for quick release and replacement of the attachment strap, simplifying repair operations while maintaining the permanent, robust mounting base.
4Ease of operation
If the lashing strap is left exposed and accessible, then the ease of operation is improved, but the risk of damage and safety hazards increases
Solution Approach 1:
The retractable axle stub is nested within the mounting base when not in use, protecting it from damage and eliminating it as a safety hazard. The attachment strap remains accessible when needed for operation, while the retracted components are safely stored inside the mounting base structure.

AI summary
The invention relates to a stop or lashing strap (2), a mounting base (10) for such a stop or lashing strap (2), and a stop or lashing point (1) with such a stop or lashing strap (2) and a mounting base (10). The stop or lashing strap (2) and the mounting base (10) are connected to each other via at least one axle stub (14, 16). According to the invention, the at least one axle stub (16) is retractable so that the stop or lashing strap (2) and the mounting base (10) can be locked together. This means that the stop or lashing strap (2) can only be attached to the mounting base (10) when the latter is fully assembled. This facilitates the attachment of the mounting base (10) to a support (9) or load (9) as well as subsequent work steps, such as corrosion protection or painting of the support (9) or load (9).Furthermore, in this embodiment, the stop or lashing tab (2) can be easily removed when not in use. Further advantageous embodiments relate to the pivotable mounting of the stop or lashing tab (2) relative to the mounting base (10) around the at least one axle stub (16), as well as the slidability of the stop or lashing tab (2) relative to the mounting base (10).
