Storage Tray Surface Structure for Cable Adhesion Prevention
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Cable processing devices face issues with incomplete production batches due to cable adhesion to storage trays, particularly with small cross-section cables, leading to production disruptions caused by electrostatic charging and increased adhesion of soft insulation materials.
Innovation Solution
The storage tray's cable-facing surface is structured with ribs, nubs, or beads to reduce adhesion, allowing cables to rest on these elevations rather than the smooth surface, ensuring they slide into the removal tray without sticking, with optimal rib height and spacing designed for small cross-section cables.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a smooth storage tray surface is used, then cables can slide easily, but small cross-section cables adhere to the tray due to electrostatic charging and soft insulation material adhesion
Solution Approach 1:
The storage tray surface is equipped with elevations (ribs, nubs, or beads) that create locally different properties: smooth areas where cables rest and elevated areas that prevent adhesion. This local differentiation allows cables to be supported on smooth surfaces while avoiding electrostatic adhesion on the elevated portions, solving the contradiction between easy sliding and complete transfer reliability
2Reliability
If elevations are added to the storage tray surface, then cable adhesion is reduced, but the tray structure becomes more complex
Solution Approach 1:
The storage tray surface is segmented into multiple elevations (ribs, nubs, or beads) distributed across the surface. This segmentation approach prevents cable adhesion by creating multiple small contact points rather than a continuous smooth surface, reducing the overall adhesion effect while maintaining a relatively simple overall tray structure
3Productivity
If the storage tray is pivoted to transfer cables, then production batches can be moved to the removal tray, but cables with small cross-sections stick to the tray and prevent complete transfer
Solution Approach 1:
The elevations on the storage tray create local quality differences that prevent cables from making continuous contact with the tray surface during pivoting. Small cross-section cables rest on the elevated portions rather than the flat areas, reducing adhesion forces and ensuring complete transfer to the removal tray during the pivoting motion
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This surface structure prevents cable adhesion, ensuring complete transfer of production batches and maintaining production efficiency, particularly for cables with small cross-sections, while larger cables do not experience adhesion issues.
Implementation Method 1
Cables with a small cross-section and therefore low weight per length unit often have the property of sticking to the storage tray

AI summary
The cable processing device includes processing stations for fabrication of a processed cable (3), a tray (13) for receiving the cables, a storage tray (13.1), and a removal trough (13.2). The storage tray is arranged facing a surface structure in elevated manner. The cables are selectively rested over the surface structure, such that the cables stored in the storage tray are moved into the removal trough, when the storage tray is pivoted using the elevated ribs, knobs or beads.
