Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable management solutions for installation cabinets fail to achieve high packing densities while allowing easy winding and unwinding of cables, and are not easily mountable or exchangeable.
Innovation Solution
A device comprising a carrier unit with a rotatable coil former and a bobbin featuring delimiting elements, a fastening element, and a braking device, allowing for parallel alignment to maximize packing density and easy mounting on installation cabinet surfaces, with an internal storage space for cable ends and a partitionable design for adjustable capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cable holders are firmly attached to a case or floor using an integrated latch, then the cable can be wound around the winding core, but subsequent winding or unwinding of the cable is difficult
Solution Approach 1:
The device is divided into two main segments: a fixed carrier unit attached to the installation cabinet and a rotatable coil former that can be independently rotated. This segmentation allows the cable management function to be separated from the winding operation, enabling firm attachment while maintaining easy cable winding and unwinding through independent rotation of the coil former.
Solution Approach 2:
The coil former is designed to be rotatable relative to the carrier unit, transforming the static cable holder into a dynamic system. The rotatable coil former allows the cable to be wound and unwound by rotating the coil former itself, while the carrier unit remains firmly attached to the installation cabinet, resolving the contradiction between firm attachment and ease of operation.
2Quantity of substance
If various coil formers are arranged in parallel with magnetic attachment, then the system can accommodate excess cable lengths, but the packing density is limited
Solution Approach 1:
The coil former is oriented with its axis of rotation parallel or at a small angle (no more than 45°, preferably no more than 20°, particularly preferably no more than 10°) to the stop side of the carrier unit. This dimensional orientation allows multiple coil formers to be arranged in parallel with minimal space requirements, maximizing the packing density in the installation cabinet while maintaining adequate cable accommodation capacity.
3Ease of manufacture
If the axis of rotation of the coil body is arranged perpendicular to the stop side, then the coil can be mounted, but the packing density in the installation cabinet is reduced
Solution Approach 1:
The patent changes the orientation parameter of the coil former's axis of rotation from the conventional perpendicular arrangement to a parallel or near-parallel arrangement relative to the stop side. This parameter change optimizes the space utilization in the installation cabinet, allowing multiple devices to be arranged in parallel with high packing density while maintaining the mounting capability through the carrier unit's attachment to the installation cabinet.
4Area of stationary object
If a high packing density is achieved with multiple devices, then the space utilization is maximized, but the ability to wind and unwind individual cables is impaired
Solution Approach 1:
The device segments the cable management function into a fixed carrier unit for mounting and a rotatable coil former for cable winding. This segmentation allows each coil former to be independently rotated to access and wind individual cables, maintaining ease of operation even when multiple devices are densely packed in the installation cabinet.
Solution Approach 2:
The rotatable coil former provides dynamic access to individual cables within the densely packed arrangement. By rotating the coil former, operators can easily wind and unwind individual cables without disturbing adjacent devices, preserving ease of operation while achieving high packing density in the installation cabinet.
