Solution Overview

Problem

Existing electrical installation devices with integrated lighting require complete replacement of the socket for retrofitting, making it difficult and costly to implement universal lighting in a simpler and faster manner.

Innovation Solution

A central cover with an integrated lighting device and connecting contacts that automatically make electrical contact with the device insert, allowing for easy retrofitting by replacing only the central cover, utilizing a standard device insert and incorporating a twilight sensor for automatic lighting control.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If lighting components are integrated into the device insert (base part), then lighting functionality is achieved, but retrofitting requires complete replacement of the socket

Engineering Contradiction:
Improvelighting functionalityVSAvoidretrofitting simplicity
Core Design Contradiction:
Adaptability or versatilityVSEase of manufacture

Solution Approach 1:

The patent divides the electrical installation device into two separate functional modules: the device insert (base part) containing the electrical connection components, and the central cover containing the lighting device. This segmentation allows the lighting functionality to be added or replaced by changing only the central cover, enabling simple retrofitting without replacing the entire socket or dismantling the device insert.

Inventive Principle:
Principle #1Segmentation

2Ease of manufacture

If electroluminescent film is used with lateral plug-in contacts, then lighting is achieved, but connection assembly becomes difficult

Engineering Contradiction:
Improvelighting implementationVSAvoidconnection assembly
Core Design Contradiction:
Ease of manufactureVSEase of operation

Solution Approach 1:

Instead of inserting contacts laterally into the insulating part as in prior art, the patent inverts the connection approach by having the connecting contacts protrude from the central cover in the joining direction (toward the device insert). This allows the contacts to automatically engage with the contact elements of the device insert during assembly, making the connection process simpler and more intuitive.

Inventive Principle:
Principle #13The other way round (Inversion)

3Ease of manufacture

If standard device insert is used with customized central cover, then retrofitting is simplified, but connecting contacts must be adapted to existing contact elements

Engineering Contradiction:
Improveretrofitting simplicityVSAvoidcontact compatibility
Core Design Contradiction:
Ease of manufactureVSAdaptability or versatility

Solution Approach 1:

The patent designs the connecting contacts on the central cover to be adaptable to different contact element configurations in the device insert. The contacts are positioned and configured to work with standard device inserts while maintaining the ability to accommodate variations, ensuring broad compatibility across different socket types and enabling universal retrofitting application.

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