Solution Overview

Problem

Existing electrical/electronic flush-mounted installation devices risk damaging external lines during installation and pose challenges in cleaning and maintenance, particularly when renovating, as the sockets are susceptible to dirt and difficult to access.

Innovation Solution

An electrical/electronic flush-mounted installation device with a separate flush-mounted pot having terminals and an electrical contacting device located in the bottom area, allowing for safe connection of external lines and easy maintenance without risking damage or contamination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the socket is positioned flush with the wall for easy access, then ease of operation is improved, but susceptibility to dirt and contamination increases

Engineering Contradiction:

Improveaccessibility of socketVSAvoidcontamination of socket

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent inverts the conventional socket positioning by placing the electrical contacting device in the bottom area of the housing rather than flush with the wall. This inversion allows the socket to be positioned where it cannot be contaminated by paint or glue during wallpapering, while still maintaining accessibility for maintenance through the device box opening.

Inventive Principle:

Principle #13The other way round (Inversion)

2Ease of manufacture

If external lines are routed through the device box during installation, then ease of installation is improved, but risk of crushing or damaging lines increases

Engineering Contradiction:

Improveease of installationVSAvoidintegrity of external lines

Core Design Contradiction:

Ease of manufactureVSReliability

Solution Approach 1:

The patent extracts the external line connection point from the device box interior and relocates it to the bottom area of the housing. This extraction allows external lines to be connected to terminals in a protected location outside the device box, eliminating the risk of crushing or damaging lines while routing them through the device box during installation.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of operation

If the contacting device is positioned for easy connection during assembly, then ease of operation is improved, but susceptibility to contamination during renovation increases

Engineering Contradiction:

Improveease of connectionVSAvoiddirt from paint or glue

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent changes the spatial dimension of the contacting device positioning from the wall-facing dimension to the bottom dimension of the housing. This dimensional change allows the contacting device to be positioned in a location that is protected from wall renovation activities while still being accessible for connection purposes through the device box opening.

Inventive Principle:

Principle #17Another dimension (Dimensionality change)

AI summary

The device has a built-in pot (4) suitable for mounting into a commercial and/or standardized built-in device socket (18). The pot includes a housing (6) with a support ring (5), where connection terminals (8) for connecting external conductors are fastened in a bottom region of the housing. An electrical contacting device (9) of the pot is fastened in the bottom region of the housing. The electrical contacting device works together with another electrical contacting device of an electronic insert (1) e.g. LED module. The housing and the support ring are integrally designed.
