Solution Overview

Problem

Existing electrical installation devices lack the ability to customize lighting color according to user preferences, national safety regulations, and technical requirements, limiting adaptability and functionality.

Innovation Solution

An electrical installation switch with a light insert featuring a light device and an electrical selector switch that allows users to choose between different colors by actuating the switch, utilizing single-color or multi-colored LEDs and pulse width modulation for color selection and dimming, integrated into a compact housing with accessible selector switch elements for easy operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a conventional light insert is used to provide lighting in an electrical installation device, then the lighting function is achieved, but the ability to customize lighting color according to user preferences and requirements is lost

Engineering Contradiction:

Improvelighting color customizationVSAvoidlight insert structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The light insert is divided into separate functional modules: a housing, a light device with multiple single-color LEDs (red, green, blue), and an electrical selector switch. This segmentation allows each component to perform its specific function independently while enabling color customization through the combination of modular elements.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The electrical selector switch enables dynamic reconfiguration of the lighting system by allowing users to select different color combinations in real-time. The switch can be actuated from outside the housing to change the lighting color without requiring disassembly or complex internal mechanisms.

Inventive Principle:

Principle #15Dynamics

2Adaptability or versatility

If multiple single-color LEDs are used to achieve color customization, then lighting adaptability is improved, but the device complexity and spatial requirements increase

Engineering Contradiction:

Improvelighting color optionsVSAvoidlight insert size

Core Design Contradiction:

Adaptability or versatilityVSVolume of moving object

Solution Approach 1:

Multiple single-color LEDs (red, green, blue) are merged into a single light device housed within one housing. This consolidation achieves color customization capabilities while maintaining a compact form factor, as the LEDs share common mounting space and electrical connections within the integrated light device assembly.

Inventive Principle:

Principle #5Merging (Combining)

3Ease of operation

If the selector switch is made accessible from outside the housing, then ease of operation is improved, but the housing design becomes more complex

Engineering Contradiction:

Improvecolor selection accessibilityVSAvoidhousing structure

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The actuating elements of the electrical selector switch are extracted and made accessible through openings in the housing. This allows users to operate the switch from outside the housing without requiring disassembly, while the housing structure itself remains relatively simple with only minimal openings needed for accessibility.

Inventive Principle:

Principle #2Taking out (Extraction)

4Volume of moving object

If a multi-colored LED is used instead of multiple single-color LEDs, then the volume of the light insert is reduced, but the precision of color selection and uniformity may be compromised

Engineering Contradiction:

Improvelight insert compactnessVSAvoidcolor uniformity

Core Design Contradiction:

Volume of moving objectVSManufacturing precision

Solution Approach 1:

Instead of using a single multi-colored LED, the invention employs multiple single-color LEDs (red, green, blue) positioned at specific locations within the housing. Each LED emits light of a specific wavelength, and their combined output can be precisely controlled through the selector switch to achieve uniform and accurate color selection, with each LED contributing its specialized function to the overall lighting performance.

Inventive Principle:

Principle #3Local quality
