Distributor Box Eyelet Element for External Cable Routing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing junction boxes with eyelet elements for cable guides often obstruct access during assembly work, as the cable guides are typically inside the box and do not allow for easy routing of cables from above without impeding access.
Innovation Solution
A distribution box design that allows the eyelet element to be attached to the vertical side, enabling cable guides to be routed externally from above, with a connecting device on the box bottom or side wall, and the eyelet element can be rotated or offset to form both inner and outer guides, allowing for adaptable cable routing without obstructing access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If the eyelet element is positioned inside the distribution box to form a cable guide, then cable management is improved, but access to the distribution box is obstructed during assembly work
Solution Approach 1:
The eyelet element is made movable between an inner position (inside the distribution box) and an outer position (outside the distribution box). This dynamic repositioning allows the cable guide to be moved from an obstructing position to a non-obstructing position during assembly work, while still providing cable management when needed.
Solution Approach 2:
The eyelet element can be positioned in different spatial locations relative to the distribution box - either inside the box or outside the box. This dimensional flexibility allows the same component to serve different functions depending on its position, resolving the contradiction between cable management and access.
2Device complexity
If the eyelet element is fixed in one position, then the structure is simple, but the cable guide cannot be adapted between inner and outer routing
Solution Approach 1:
The eyelet element incorporates a movable connection mechanism that allows it to be repositioned between inner and outer locations. This dynamic feature provides adaptability while maintaining relatively simple construction through the use of a movable connection device.
Solution Approach 2:
The same eyelet element serves multiple functions by being positionable in different locations - it can form a cable guide inside the distribution box or outside the distribution box. This multi-functionality increases versatility without requiring multiple separate components.

AI summary
The distribution box (1) comprises an eyelet element (8) for formation of a cable guide (14,15). A mounting unit is provided for mounting the eyelet element at the distribution box formed under the cable guide outside the box. The eyelet element forms the cable guide by rotating at 180 degree outside the box or around the eyelet width, which is attached displaceable at the distribution box.
