Concealed Installation Body Cable Duct for Leak-Tight Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Sealing the cable bushing of flush-mounted installation bodies is complex and prone to errors, which poses a challenge in ensuring the protection of the surrounding environment against water leakage.
Innovation Solution
A flush-mounted installation body design featuring a plate attached to the housing that forms a cable channel with the outer wall, creating a defined space for the cable bushing, allowing for easier sealing and protection against moisture ingress, using a cable duct and sealant to ensure a liquid-tight receiving space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the cable entry is sealed using conventional methods, then water leakage protection is achieved, but the sealing process becomes complex and error-prone
Solution Approach 1:
The sealing function is segmented into two parts: the cable bushing itself and the separate plate with integrated cable duct. The plate is fastened to the housing to form a defined cable channel that guides the cable from the cable leadthrough to the functional unit, separating the sealing function from the cable routing function and simplifying the overall sealing process
Solution Approach 2:
The plate acts as an intermediary element between the housing and the cable. It forms a cable duct that provides a defined pathway for the cable, and its integration with the housing creates a sealed environment without requiring complex sealing mechanisms at the cable entry point
2Reliability
If the cable entry is sealed using conventional methods, then water leakage protection is achieved, but the error rate in sealing increases
Solution Approach 1:
The plate is pre-fastened to the housing to form the cable duct before the cable is routed through it. This preliminary action creates a defined and stable cable pathway, ensuring proper sealing positioning and reducing errors during the cable installation process
Solution Approach 2:
By separating the sealing structure (housing with cable bushing) from the cable guidance structure (plate with cable duct), the invention reduces the complexity of achieving precise sealing, as each component can be manufactured and assembled independently with standard tolerances
3Ease of manufacture
If a plate is attached to form a cable duct, then sealing complexity is reduced, but the device structure becomes more complex
Solution Approach 1:
The plate serves multiple functions: it forms the cable duct for cable routing, provides a sealing surface when fastened to the housing, and creates a defined cable channel. This multi-functionality justifies the additional component while simplifying the sealing process
Solution Approach 2:
The plate is attached only at the specific location where cable routing and sealing are needed (the outer wall of the housing), rather than modifying the entire housing structure. This localized approach minimizes the increase in overall device complexity while achieving the sealing objective
