Transport Unit Force-Absorbing Structure for Coil Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Coils of collapsible container blanks with differing densities cause instability and damage during transport due to interleaving and 'upsetting', leading to increased costs and environmental issues, as they cannot be stacked securely and the burden of proof for damage is difficult to establish.
Innovation Solution
A transport unit comprising a load carrier with a load distributing element and a tightening strap that forms a force-absorbing structure, where the tightening strap encloses this structure in the longitudinal direction of the deckboards, preventing vertical force from being absorbed by the container blanks and allowing multiple coils to be stacked without damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If coils of container blanks with differing densities are stacked on top of each other during transport, then transport efficiency is improved, but instability and interleaving of turns occur causing damage to the container blanks
Solution Approach 1:
A transport device with a support surface and securing element is introduced as an intermediary between the coils and the transport environment. The support surface provides a stable base for stacking, while the securing element actively prevents interleaving and movement, allowing reliable stacking despite density differences in the container blanks
Solution Approach 2:
The transport device provides preliminary support and protection to the coils before damage can occur. The support surface prevents initial instability, and the securing element is positioned to prevent interleaving before it can cause damage during transport
2Reliability
If coils are transported one by one in separate boxes to prevent damage, then stability and protection of container blanks are improved, but packing costs and environmental impact increase
Solution Approach 1:
Multiple coils that would traditionally require separate boxing are merged into a single transport unit. The common transport device with its support surface and securing element provides collective protection, eliminating the need for individual boxes while maintaining protection against damage
Solution Approach 2:
The transport device serves multiple functions simultaneously: it provides a support surface for stacking, incorporates securing elements to prevent interleaving, and acts as a protective structure. This multi-functionality replaces multiple separate packing solutions
