Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electrical installation devices with orientation lights often have a dominant and direct lighting effect, which can be excessive and lack flexibility in operation with or without the lighting feature, and may require a neutral conductor or cause noise.
Innovation Solution
An electrical installation device with a panel light integrated into a viewing frame, connected to a power box via a plug, providing indirect lighting that can be activated or deactivated, using an electroluminescent film with low power consumption and no need for a neutral conductor, and allowing color selection through filters, suitable for retrofitting standard switches.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a light guide element or electroluminescent light area is integrated into the switch to provide orientation light, then the installation device can be located in the dark, but the lighting effect becomes dominant and direct, which is excessive
Solution Approach 1:
A diffusing element is introduced as an intermediary between the light source (light guide element or electroluminescent light area) and the surrounding area. This diffusing element scatters the light to create an indirect, soft illumination effect rather than direct lighting, reducing the dominance of the orientation light while maintaining its visibility function for locating the installation device in the dark.
2Adaptability or versatility
If the electrical installation device is designed to always include orientation light functionality, then lighting is always available, but the device cannot be operated without the orientation light and requires additional conductors
Solution Approach 1:
The orientation light functionality is made dynamic and optional rather than fixed. The light guide element or electroluminescent light area is connected via a plug connection that can be selectively engaged or disengaged. This allows the installation device to operate with or without the orientation light feature, providing adaptability to different user needs and installation scenarios without requiring permanent additional conductors.
3Illumination intensity
If conventional lighting elements are used in the installation device, then sufficient illumination is provided, but power consumption is high and a neutral conductor is required
Solution Approach 1:
The lighting technology parameter is changed from conventional high-power light sources to low-power electroluminescent light areas or efficiently designed light guide elements. This parameter change enables sufficient illumination for orientation purposes while dramatically reducing power consumption and eliminating the requirement for a neutral conductor, as these lighting elements can operate with minimal current draw from the existing live and neutral lines.

AI summary
The installation device incorporates a viewing frame (14) into which is integrated a two-dimensional luminaire (18) in the form of a luminescent film. The viewing frame (14) consists of a basic frame (16) and a transparent covering frame (17) surrounding it, which encloses the two-dimensional luminaire (18). The two-dimensional luminaire (18) is connected via a plug (24) to a switch box (22) attached to the base (10) of the switch.
