Sanitary Wall Connection Box Sealing Membrane for Cable Feedthrough
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary wall-mounted connection box units face challenges in providing a fluid-tight electrical cable bushing and efficient assembly, often requiring separate seals and increased manufacturing effort due to the lack of liquid-tightness and complex cable routing.
Innovation Solution
A sanitary wall-mounted connection box unit with a base section made from sealingly flexible material, featuring a closure membrane for the electrical cable feedthrough opening, which allows for easy and reliable fluid-tight sealing without additional seals, and a design that integrates both fluid and electrical line connections for a compact configuration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional electrical cable penetration methods are used through housing walls, then cable routing is possible, but fluid-tightness is compromised and additional separate seals are required
Solution Approach 1:
The patent combines the sealing function and cable routing function into a single integrated closure membrane structure. The closure membrane is a pre-formed sealing element with an integrated cable opening, eliminating the need for separate seals and cable glands. This merging of functions maintains fluid-tightness while simplifying the overall sealing structure.
Solution Approach 2:
The closure membrane is pre-formed with the cable opening already integrated into its structure before installation. This preliminary preparation of the sealing element with built-in cable access eliminates the need for post-installation modifications or additional sealing components, ensuring fluid-tightness is maintained from the outset.
2Ease of operation
If separate seals are used for cable penetration, then cable routing is possible, but manufacturing effort and assembly complexity increase
Solution Approach 1:
The closure membrane integrates multiple functions (sealing, cable routing, and structural support) into a single component. This reduces the number of parts that need to be manufactured, stored, and assembled, directly lowering manufacturing effort and assembly complexity while maintaining ease of operation.
Solution Approach 2:
The closure membrane serves multiple purposes simultaneously: it provides fluid-tight sealing, creates cable access openings, and acts as a structural element of the housing. This multi-functionality reduces the total component count and simplifies assembly procedures without compromising operational ease.
3Ease of manufacture
If conventional cable routing methods are used, then cable access is possible, but additional seals and increased manufacturing effort are required
Solution Approach 1:
The closure membrane combines the sealing material and cable access feature into a single integrated component. This eliminates the need for multiple separate sealing elements and cable glands, reducing both the quantity of sealing components and the manufacturing effort required to produce and assemble them.
