Solution Overview

Problem

Existing methods for mounting lead-through assemblies in walls require a double wall construction for stability, which is not always desirable, and disrupt the moisture barrier when multiple elements protrude through the wallboard.

Innovation Solution

A method using a mounting bracket that secures the lead-through device with a retainer, allowing for clamping force between the support section and retainer to fix the assembly in a single wallboard, with securing means inserted directly through the wall from the opposite side, minimizing protrusions and facilitating installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If a double wall construction with plywood sheet is used to provide stable mounting support for the lead-through device, then the stability and support capability is improved, but the device complexity and installation complexity increases

Engineering Contradiction:
ImprovestabilityVSAvoidcomplexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The patent extracts the mounting bracket as a separate, removable component that can be installed independently within the wall cavity. This allows the bracket to provide stable support without requiring a complex double wall construction, as the bracket itself becomes the stable mounting platform for the lead-through device

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The mounting system is segmented into distinct components: the mounting bracket that attaches to the wall structure, and the lead-through device that attaches to the bracket. This segmentation allows each component to be optimized independently and simplifies installation, as the bracket can be installed first to provide stable support before the lead-through device is mounted

Inventive Principle:
Principle #1Segmentation

2Ease of operation

If multiple elements (guiding plate, washer, securing means) protrude through the wallboard to facilitate installation, then the ease of operation is improved, but the moisture barrier integrity is compromised

Engineering Contradiction:
Improveease of installationVSAvoidmoisture barrier disruption
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The mounting bracket is installed preliminarily within the wall cavity before the lead-through device is mounted. The bracket extends through the wallboard with its support section positioned to receive the lead-through device, allowing subsequent installation without requiring additional protruding elements that would disrupt the moisture barrier

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The mounting bracket acts as an intermediary component that facilitates the connection between the lead-through device and the wall structure. It provides the necessary support and alignment functions that would otherwise require multiple protruding elements, thereby simplifying the installation process while maintaining moisture barrier integrity

Inventive Principle:
Principle #24Intermediary (Mediator)

3Device complexity

If a mounting bracket with support section is used to secure the lead-through device within a single wallboard, then the device complexity is reduced, but the mounting stability may be compromised

Engineering Contradiction:
ImprovecomplexityVSAvoidstability
Core Design Contradiction:
Device complexityVSStability of the object's composition

Solution Approach 1:

The mounting bracket utilizes the third dimension (depth) of the wall cavity to provide stable support. By extending the support section into the wall cavity and positioning it against the back side of the wallboard, the bracket creates a stable mounting platform without requiring additional wall layers, thus maintaining stability while reducing complexity

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

AI summary

A method for mounting a lead-through assembly (1) in a wall (5), the lead-through assembly being adapted to provide a fluid communication through the wall in a direction of extension from a first side (7) of the wall to a second side (9) of the wall, the lead-through assembly comprising: - a lead-through device (3) comprising a passage portion (11) configured to extend through an opening in the wall to the second side of the wall and being adapted to provide the fluid communication, - at least one support section (14, 14') comprising an abutment surface (16, 16') configured to abut a first wall surface (17) of the wall, the first wall surface being located on the first side of the wall, - a retainer (19) being adapted to be attached to passage portion, the retainer comprising a contact surface (21) adapted to press against a second wall surface (23) located on the second side of the wall when the retainer is attached to the passage portion, the method comprising: - arranging (101) the passage portion of the lead-through device through the opening in the wall, such that the abutment surface abuts the first wall surface, - securing (102) the at least one support section to the first wall surface, - fixing (103) the lead-through assembly in the wall by attaching the retainer to the passage portion on the second side of the wall, such that the contact surface presses against the second wall surface of the second side of the wall, thereby creating a clamping force between the abutment surface of the at least one support section and the contact surface of the retainer. The present invention also relates to a lead-through assembly adapted to provide fluid communication through a wall in a direction of extension from a first side of the wall to a second side of the wall, which assembly can be mounted using the above method.
