Cargo Beam Fastening Tip with Rotating Stopping Plate
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing fastening systems for connecting cargo support beams to tracks in containers are prone to damage from external forces and are inconvenient to operate, with limited manipulation space and difficulty in disassembly.
Innovation Solution
A fastening tip with an L-shaped stopping plate, torsional spring, and obliquely arranged operating fins, which allows for rotation and locking of the stopping plate within positioning holes, enabling easy assembly and disassembly while protecting against damage from external forces.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the manipulation portion of the barrier strip is located on the top and higher than the upper surfaces of the fasteners, then it is convenient to operate by finger, but the manipulation portion is easy to be bent or damaged by the cargos and the support beam cannot be disassembled smoothly
Solution Approach 1:
The manipulation portion is moved from a vertical position (on top of the fastener) to a horizontal position (extending laterally from the side). This dimensional change allows the manipulation portion to be accessed from the side rather than from above, avoiding damage from overhead cargos while maintaining finger accessibility for operation.
2Ease of operation
If the manipulation portion is provided on the top of the barrier strip, then it is convenient to operate, but the manipulation space is small and it is inconvenient for manipulation
Solution Approach 1:
The manipulation portion extends laterally from the side of the fastener body rather than vertically from the top. This dimensional relocation creates additional manipulation space by utilizing the lateral dimension, allowing fingers to access and operate the manipulation portion more easily without spatial constraints from above.
3Reliability
If the stopping plate top surface is located within the positioning hole and resists against the inner edge, then the structure is protected from damage, but the assembly and disassembly operations become more complex
Solution Approach 1:
The manipulation portion serves as an intermediary element that transmits the operator's force to the stopping plate, enabling control of the stopping plate's rotation and positioning without requiring direct manipulation of the stopping plate itself. This intermediary mechanism simplifies the assembly and disassembly operations while maintaining the protective positioning of the stopping plate within the positioning hole.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution provides a secure and convenient method for connecting and disconnecting cargo support beams, preventing damage from external forces and enhancing operational ease by allowing the stopping plate to rotate and disengage from positioning holes, thus improving the structural integrity and usability of the fastening system.
Implementation Method 1
a torsional spring for enabling the top portion of the stopping plate to rest against the edge of the positioning hole
Implementation Method 2
a torsional spring for enabling the top portion of the stopping plate to rest against the edge of the positioning hole

AI summary
The present invention discloses a fastening tip for connecting a cargo support beam to a track, which comprises a first side plate (1), a second side plate (2), a stopping plate (3), a torsional spring (5) and a lining plate (4), characterized in that, the top surface of the top portion of the stopping plate (3) is flat, and the stopping plate (3) has an operating fin (32) exposed outside; the lining plate (4) engages the stopping plate (3) when the top portion of the stopping plate (3) tightly resists against the edge of the positioning hole (100). In the present invention, the damage due to the extrusion of cargos or by an external force is effectively prevented from; in addition, the manual operation space is increased, and the operation is more convenient.
