Solution Overview

Problem

Existing electrical installation devices lack the ability to provide variable and adaptable lighting, which is visually appealing and can meet different lighting requirements at various installation locations without requiring device-specific changes.

Innovation Solution

Integration of an adjustable lighting element that can be axially adjusted within the front element, featuring a translucent area for light emission, allowing for customizable lighting intensity and distribution, and incorporating a spring-loaded latching mechanism for easy actuation, along with a light-guiding body for uniform illumination and additional information display.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If a fixed lighting device is integrated into the front element, then the lighting function is provided, but the lighting cannot be adapted to different installation requirements and locations

Engineering Contradiction:
Improvelighting adaptabilityVSAvoiddevice structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lighting element is made adjustable and movable within the front element, allowing it to be positioned at different locations and orientations. This dynamic capability enables the same device to adapt to various lighting requirements at different installation locations without requiring device-specific changes, thus resolving the contradiction between adaptability and device complexity.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The installation device incorporates a universal lighting element that can serve multiple lighting functions across different installation locations. The adjustable lighting element can be configured to provide full lighting, orientation lighting, or complete covering, making the device versatile and adaptable to various requirements without needing multiple specialized devices.

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

2Adaptability or versatility

If the lighting element is made adjustable, then variable lighting can be provided, but the device structure becomes more complex

Engineering Contradiction:
Improvelighting variabilityVSAvoidadjustable mechanism
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lighting element incorporates adjustable components that allow variation in lighting intensity, distribution, and positioning. The mechanism enables the lighting element to be moved to different positions and orientations within the front element, providing variable lighting while maintaining a manageable device structure through integrated design.

Inventive Principle:
Principle #15Dynamics

3Ease of manufacture

If the light exit surface is visible when not in use, then the lighting function is apparent, but the surface of the front element is interrupted and aesthetics are reduced

Engineering Contradiction:
Improvelighting integrationVSAvoidsurface continuity
Core Design Contradiction:
Ease of manufactureVSShape

Solution Approach 1:

The lighting element is designed to be movable and adjustable within the front element, allowing it to be positioned in locations that minimize visual interruption of the surface. When not in use, the lighting element can be retracted or positioned to maintain surface continuity, while still providing apparent lighting functionality when activated.

Inventive Principle:
Principle #15Dynamics
