Solution Overview

Problem

Existing surface-mounted switches and sockets lack enhanced functionality and flexibility, particularly in enabling additional electrical or electronic components without requiring replacement of the installation device.

Innovation Solution

A wall insert with an additional housing that can be retrofitted to existing devices, providing a sealed closure and accommodating components like lighting elements, radio adapters, or motion detectors, while maintaining protection against moisture through a sealing cover.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a standard wall insert is used for sealed closure, then the housing recess is sealed, but the functionality of the installation device remains limited

Engineering Contradiction:
ImprovefunctionalityVSAvoidstructure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent applies nesting by placing an additional housing inside the installation device housing, which contains further sub-components like lighting elements or electronic components. This nested structure allows multiple functional layers within a single device without requiring separate external components, thereby expanding functionality while maintaining a unified structural appearance.

Inventive Principle:
Principle #7Nested doll (Nesting)

Solution Approach 2:

The wall insert is designed as a multi-functional component that combines both sealing function and additional functional housing. The additional housing can accommodate various components (lighting, electronics, etc.), making the single wall insert structure serve multiple purposes: sealing the housing recess, providing structural support, and housing additional functional elements.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If additional components are integrated into the installation device, then functionality is expanded, but the original device must be replaced

Engineering Contradiction:
ImprovefunctionalityVSAvoidretrofitting cost
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The invention segments the installation device into modular components: the original installation device housing, the wall insert with sealing function, and the additional functional housing. This segmentation allows the additional functionality to be added as a separate module (the additional housing within the wall insert) rather than requiring replacement of the entire original device, enabling cost-effective retrofitting.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The wall insert with the additional housing is pre-configured during manufacturing with the capability to house various functional components. This preliminary preparation allows the device to be retrofitted with different functional elements (lighting, electronics, etc.) later without requiring complex modifications, as the structural framework is already in place.

Inventive Principle:
Principle #10Preliminary action

3Ease of operation

If components are exposed in the installation device, then functionality is accessible, but protection against moisture is reduced

Engineering Contradiction:
Improvecomponent accessibilityVSAvoidmoisture protection
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent employs sealing elements (flexible membranes/shells) that create protective barriers between the internal components and the external environment. These sealing elements allow the device to maintain protection against moisture while still enabling controlled access to components through the sealed structure, such as via removable covers or access panels that maintain the seal when closed.

Inventive Principle:
Principle #30Flexible shells and thin films
