Liner Clip and Cord Mounting for Taut Container Sheet Securing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing sheet materials in shipping containers and similar structures face challenges due to varying lashing point locations and spacings, leading to difficulties in achieving a tight fit and preventing sagging, which can compromise temperature protection and cargo integrity.
Innovation Solution
A mounting combination using folded sheet material with integrated cords and clips, along with cable ties and hooks, allows for adjustable and secure attachment to lashing points, ensuring the sheet material remains taut and upright.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If fixed attachment hooks are used on the liner, then the liner can be attached to lashing points, but the varying locations and spacing of lashing points make satisfactory installation difficult or impossible
Solution Approach 1:
The patent applies the dynamics principle by making the attachment hooks movable along the webbing straps instead of fixed. The hooks can slide to different positions on the webbing, allowing the liner to adapt to varying lashing point locations and spacings. This dynamic adjustment capability enables the same liner to be installed on different container types and configurations.
2Ease of operation
If a single piece of webbing is used on each side of the container with hooks threaded through, then attachment is possible, but the liner sags to an unacceptable extent
Solution Approach 1:
The patent applies segmentation by dividing each side webbing into multiple separate webbing pieces, each with its own attachment hook. This allows independent tensioning of each webbing segment, enabling the liner to be pulled taut and secured firmly without sagging, while still maintaining ease of attachment through the same hook-lashing point mechanism.

AI summary
A mounting is disclosed for securing in place a sheet (56) which constitutes a liner, cover or curtain. The sheet has an elongate attachment zone (60) which is thicker than the material of the sheet. The mounting including a clip (10.2) which is formed with an elongate hollow portion (12) having a longitudinal slit (14) along the length thereof. The attachment zone of the sheet is in the hollow portion of the clip with the sheet emerging from the clip through the slit. A cord (62) is connected to a lashing point (64). The clip (10.2) has a passageway (40) through which the cord (62) passes thereby to attach the clip and the attachment zone to the lashing point.
