Modular Cable Penetration Frame With Normal-Direction Bush Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable entry systems and grommets are prone to errors in handling and assembly, require dismantling of the frame for maintenance, and restrict the flexible use of grommets of different diameters.
Innovation Solution
A frame with separated strips of lower height and connecting devices that allow cable grommets to be mounted only in a normal direction, accommodating various grommet sizes without requiring a specific frame for each size, and enabling easy installation and maintenance by allowing individual grommet replacement without disassembling the frame.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If cable grommets are installed before assembling the frame, then the frame structure is stable, but the assembly process becomes complex and time-consuming
Solution Approach 1:
The frame is divided into separate modular sections with strips that can be assembled independently. Cable grommets are integrated into these modular sections rather than requiring pre-installation, allowing the frame to be assembled in a simplified sequence while maintaining structural stability through the modular design.
2Ease of manufacture
If the frame is designed with fixed structure, then manufacturing is simple, but maintenance work becomes difficult
Solution Approach 1:
The frame is segmented into modular sections that can be independently accessed and maintained. Individual cable grommets are integrated into these modular sections, allowing a single grommet to be replaced by accessing only its specific module rather than dismantling the entire frame, thus maintaining manufacturing simplicity while enabling easy maintenance.
Solution Approach 2:
The frame incorporates dynamic access mechanisms that allow individual modular sections to be opened or accessed without dismantling the entire structure. This enables maintenance workers to reach specific cable grommets locally, combining the simplicity of a fixed frame structure with the flexibility needed for easy maintenance.
3Ease of manufacture
If connecting devices are arranged with equal distances, then manufacturing is simple, but assembly precision is reduced
Solution Approach 1:
The connecting devices are arranged with varying distances according to the specific positioning requirements of each cable grommet. This local customization of spacing allows precise alignment and positioning for each grommet while maintaining relatively simple manufacturing processes, as the varying distances are built into the modular frame sections during production rather than requiring complex post-assembly adjustments.

AI summary
The invention relates to a frame (1, 1a, 1b) for a cable penetration system. Said frame, which is used for receiving a plurality of bushes (20, 120, 220), comprises at least one strip (2, 12) that is arranged at a distance from the frame and is lower than the adjacent frame. Connection devices (3, 3', 3") suitable for receiving suitable mating pieces (23, 123, 223) for the connection devices are disposed on the strip (2, 12), the mating pieces being disposed on bushes (20, 120, 220). The connection devices (3, 3', 3") are arranged in such a way that bushes can be mounted in the frame essentially only in the direction normal to the frame. The invention further relates to a bush (20, 120, 220) for a cable penetration system. Said bush, which is to be received in a frame, comprises a main body, inside which a through-hole (21, 121, 221) is provided from a top side to a bottom side in the normal direction in order to receive a cable. The bush comprises at least one strip (22, 122, 132, 222, 232, 322) which is arranged at a distance from the main body and is lower than the adjacent main body. Connection devices (23, 123, 223) suitable for receiving suitable mating pieces (3, 3', 3") for the connection pieces are disposed on the strip, the mating pieces being disposes on a frame. The connection devices (23, 123, 223) are arranged in such a way that the bush can be mounted in the frame essentially only in the direction normal to the frame, at least two connection devices (3, 3', 3") being arranged on the strip (2, 12) for each bush that is to be mounted.
