Lashing Aid Device for IBC Frame Fixation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for securing intermediate bulk containers (IBCs) during transport often result in damage due to inadequate lashing devices that are not strong or stable enough, leading to leakage or material loss, and require additional aids for proper fixation.
Innovation Solution
A lashing aid device that attaches to the frame of IBCs using frame fixation means for frictional or clamping engagement, featuring a securing surface with aligned rims to guide straps and prevent slipping, allowing for secure attachment to horizontal bars and absorption of lashing forces without additional tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If straps are applied directly to IBCs during lashing, then lashing is achieved, but container damage occurs with leakage or material loss
Solution Approach 1:
The lashing aid device acts as an intermediary between the lashing strap and the IBC container. The device includes a protective element that contacts the container surface while the strap contacts the device, preventing direct strap-to-container contact and distributing pressure away from vulnerable container points.
Solution Approach 2:
The device incorporates cushioning or protective elements positioned in advance at locations where straps will contact the container. This pre-positioned protection prevents damage before it occurs during the lashing process, addressing the harmful effect of concentrated strap pressure.
2Manufacturing precision
If additional aids are used for fixation during lashing, then strap positioning is improved, but device complexity increases
Solution Approach 1:
The device combines multiple functions into a single integrated unit: it provides protective cushioning, defines strap positioning through built-in guides or ridges, and ensures fixation stability through its attachment mechanism to the container frame. This eliminates the need for separate additional aids for each function.
Solution Approach 2:
The lashing aid device is designed as a multi-functional component that simultaneously protects the container, positions the strap at the correct height, and maintains stability during lashing. This universal design reduces the total number of components needed while achieving multiple objectives.
3Object-affected harmful factors
If known edge protectors are used, then some protection is provided, but they are not strong or stable enough when straps are applied
Solution Approach 1:
The device employs composite construction combining rigid structural elements for strength and stability with softer protective elements for cushioning. This composite approach enables the device to withstand strap loading forces while maintaining protection capabilities and positional stability.
Solution Approach 2:
The device incorporates curved or arcuate geometric features that distribute strap forces more effectively across its structure. The curved design provides structural strength while accommodating the container corners and distributing pressure, enhancing stability under load compared to straight-edged protectors.
4Object-affected harmful factors
If load is divided over two bands, then pressure on container is reduced, but additional positioning aids are required
Solution Approach 1:
The device is designed to accommodate and position multiple lashing bands simultaneously through integrated guides or channels. This merging of positioning functions for multiple bands into a single device eliminates the need for separate positioning aids for each band while maintaining proper spacing and alignment.
