Sanitary Connection Box Sealing for Electric Line Feed-Through
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing sanitary wall installation connection box units face challenges with non-liquid tightness during electric cable feed-throughs, requiring additional seals that compromise fluid conduit functionality.
Innovation Solution
The connection box unit incorporates a base portion made of sealing resilient material for the electric line feed-through region, with a closure membrane providing a fluid-tight seal without needing a separate seal, allowing for reliable electric line feed-through while maintaining fluid conduit functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate seal is added to achieve fluid-tight electric line feed-through, then sealing reliability is improved, but device complexity and installation difficulty increase
Solution Approach 1:
The sealing function is merged with the base portion material itself. The base portion is made of sealing resilient material that inherently provides fluid-tight sealing at the electric line feed-through opening, eliminating the need for separate seal components.
Solution Approach 2:
The base portion material serves multiple functions simultaneously: it provides structural support, creates the feed-through opening, and provides fluid-tight sealing. The material's inherent resilience to sealing enables it to self-seal around the electric line without additional sealing components.
2Reliability
If additional seals are installed for electric cable feed-through, then sealing reliability is improved, but installation time and complexity increase
Solution Approach 1:
The base portion automatically provides fluid-tight sealing through its material properties. When an electric line is inserted through the feed-through opening, the sealing resilient material inherently seals around it without requiring separate seal installation steps, significantly reducing installation time.
Solution Approach 2:
The sealing function is extracted from the list of installation steps and integrated into the base portion material itself. This eliminates the separate action of installing seals during assembly, streamlining the installation process.
3Reliability
If a closure membrane is used for electric line feed-through, then fluid-tight sealing is achieved, but manufacturing complexity increases
Solution Approach 1:
The closure membrane function is merged with the base portion. The base portion is made of sealing resilient material that inherently provides the closure and sealing functions, eliminating the need for a separate membrane component and simplifying manufacturing.
Solution Approach 2:
The base portion utilizes sealing resilient material with composite properties that combine structural integrity, flexibility, and sealing capability. This material composition enables the base portion to perform multiple functions that would otherwise require separate components.

AI summary
A sanitary wall installation connection box unit, including a box housing body having a rear-side base portion and a sleeve portion projecting to the front from the base portion, which sleeve portion peripherally surrounds a sanitary component mounting space, which space is accessible via an open front end face of the sleeve portion, and a connector body disposed on the base portion of the box housing body, which connector body includes a sanitary component connection contour facing the sanitary component mounting space, a fluid line connection interface structure accessible on an outer side of the box housing body, a fluid conduit structure for fluid connection of the fluid line connection interface structure to the sanitary component connection contour and at least one electric line feed-through opening leading from an outer side of the connector body through the connector body to the sanitary component mounting space. Illustratively, the base portion of the box housing body is made of a sealing resilient material at least in an electric line connection region adjacent to the electric line feed-through opening of the connector body, and the electric line feed-through opening of the connector body is covered on an outer side by a closure membrane made of the sealing resilient material of the electric line connection region of the base portion.
