Modular Cable-Entry Device with Adjustable Sliding Housing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wall-mounted cable passage systems for doors and windows are visible and accessible, prone to crushing or pinching, and require multiple lengths to accommodate different sizes, lacking adaptability and protection for electric cables.
Innovation Solution
A modular cable passage device with a recessed box and adjustable casing consisting of male and female parts that slide axially to accommodate varying hose lengths, featuring removable end pieces with locking mechanisms for secure attachment and length adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wall-mounted cable passage systems are used, then cable protection is provided, but the system is visible and easily accessible for tampering or damage
Solution Approach 1:
The cable passage device is nested within a recessed box that is embedded in the door or window frame. The flexible hose containing the cables is nested within the protective casing, which itself is nested within the recessed box structure. This multi-level nesting makes the cables invisible and inaccessible when the door is closed, eliminating the vulnerability to tampering while maintaining cable protection.
2Ease of manufacture
If fixed-length cable passage devices are used, then installation is simplified, but adaptability to different door sizes is reduced
Solution Approach 1:
The protective casing is segmented into a male casing part and a female casing part that can be assembled together. The flexible hose is also segmented into multiple sections that can be connected. This segmentation allows the cable passage device to be customized for different lengths and configurations while maintaining simple installation through modular assembly.
Solution Approach 2:
The cable passage device incorporates dynamic elements including a flexible hose that can bend and extend, and end pieces with adjustable positioning. The male and female casing parts can be assembled in different configurations to accommodate varying door sizes and cable lengths, providing adaptability without complicating the installation process.
3Ease of operation
If the flexible hose is made accessible for installation, then installation is easier, but the hose becomes vulnerable to crushing or pinching when the door closes
Solution Approach 1:
The flexible hose is pre-installed within the protective casing and recessed box structure before the door is assembled. The hose is routed through the male and female casing parts and secured with end pieces during the preliminary assembly stage. This preliminary action ensures the hose is protected from crushing or pinching when the door closes, while still allowing easy installation through the open recessed box during assembly.

AI summary
The present invention relates to a modular cable passage device for a door or window comprising at least one opening sash pivotally mounted on a frame, said device comprising a housing (4) adapted to be recessed and fixed in a cavity made in the frame and a flexible cable (3) for protecting the electrical cables. The housing (4) consists of two housing parts (7) and (7'), namely a male housing part (7) and a female housing part (7'), adapted to be fitted longitudinally into one another, by means of sliding means (8), relative to each other, so as to be able to adjust the length of the housing (4) according to the length of the flexible cable (3) to be received.
