Solution Overview

Problem

Existing holders for installation boxes are ineffective in inhomogeneous stone walls, such as lightweight concrete or perforated bricks, as they can slip and fail to provide a reliable fixation, and also cause deformation of the installation box.

Innovation Solution

A holder design featuring a ring-like holding element with adjustable holding arms and anchoring elements that can deform to form a barb in the wall, providing secure fixation and reduced deformation, suitable for various wall types.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional holders are used in inhomogeneous stone walls, then installation is simple, but the holder slips and reliable fixation cannot be guaranteed

Engineering Contradiction:
Improvefixation reliabilityVSAvoidwall type adaptability
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The holder is divided into a ring-like holding element and separate holding arms with anchoring elements. This segmentation allows the anchoring elements to be independently positioned and distributed along the holding arms, enabling effective anchoring in inhomogeneous wall structures while maintaining overall holder integrity and reliability across different wall types.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The anchoring elements are designed with specific local properties to penetrate and anchor into the wall structure. By distributing multiple anchoring elements along the holding arms at different positions, the holder creates localized anchoring points that adapt to varying wall densities and structures, ensuring reliable fixation regardless of wall homogeneity.

Inventive Principle:
Principle #3Local quality

2Manufacturing precision

If holding arms are fixed in position, then manufacturing is simple, but the installation box deforms during installation

Engineering Contradiction:
Improveinstallation box shape accuracyVSAvoidholder structure complexity
Core Design Contradiction:
Manufacturing precisionVSDevice complexity

Solution Approach 1:

The holding arms are designed to be movable relative to the ring-like holding element, transitioning from a folded position during installation to an extended position during use. This dynamic capability allows the holding arms to flex and adapt during the installation process, preventing deformation of the installation box while maintaining structural integrity, without requiring complex additional components.

Inventive Principle:
Principle #15Dynamics

3Reliability

If multiple anchoring elements are distributed along holding arms, then anchoring in inhomogeneous walls improves, but device complexity increases

Engineering Contradiction:
Improveanchoring reliabilityVSAvoidholder component complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Multiple anchoring elements are integrated directly onto the holding arms as a unified structure rather than being separate components. This merging approach distributes anchoring functionality along the length of the holding arms, improving anchoring reliability in inhomogeneous walls while avoiding the complexity of additional separate parts or assembly steps.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

The invention relates to a holder (1) for a junction box (2) in a wall opening (4), comprising a ring-shaped retaining element (6) which surrounds a receiving space (7) for receiving the junction box (2) and at least two retaining arms (8) which project from the ring-shaped retaining element (6). Anchoring elements (11) are arranged on the respective outer sides (9) of the retaining arms (8), which, in a mounted state, fix the holder (1) in the wall opening (4). Furthermore, at least one stop element (12) is provided for abutting the holder (1) against a wall surface (5) surrounding the wall opening (4).
