Solution Overview

Problem

Existing solutions for internal lighting in cabinets, bookcases, and refrigerators integrate the lighting device with the shelf or its supports, limiting their separate use and flexibility in application.

Innovation Solution

A compact light source with LED modules housed in a flexible structure featuring upper and lower arms and a rear wall, allowing easy mounting and removal on various flat objects, including shelves and information panels, with adjustable LED placement for even illumination and light diffusion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If the lighting device is integrated with the shelf or its supports, then the lighting function is achieved, but the flexibility and separate use of the lighting device is limited

Engineering Contradiction:
Improveflexibility and separate useVSAvoidintegrated structure
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The lighting device is segmented from the shelf structure, allowing independent installation and removal. The LED module is housed in a separate compact housing that can be mounted on shelf edges without being permanently integrated, enabling flexible reconfiguration and separate use while maintaining lighting functionality.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The lighting device is designed with universal mounting capabilities that allow it to be applied to different shelf configurations and objects. The housing can be mounted on various shelf types (glass, acrylic, wooden) and the device can be repositioned or removed as needed, providing multi-functional adaptability across different applications.

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

2Adaptability or versatility

If LED sources are mounted in a fixed housing structure, then the lighting function is stable, but the adaptability to different objects and configurations is reduced

Engineering Contradiction:
Improveapplication to different objectsVSAvoidlighting function stability
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The housing incorporates adjustable mounting mechanisms that allow dynamic reconfiguration. The LED module can be positioned at different locations along the shelf edge, and the housing can be adjusted to fit various shelf thicknesses and configurations, providing adaptability while maintaining stable lighting function through secure mounting.

Inventive Principle:
Principle #15Dynamics

Solution Approach 2:

The device allows parameter changes in mounting position, orientation, and configuration to adapt to different objects. The housing can be installed in various positions (front edge, rear edge, side edges) and the LED orientation can be adjusted, enabling the same device to reliably illuminate different shelf types and configurations.

Inventive Principle:
Principle #35Parameter changes

3Illumination intensity

If multiple LED sources are distributed in upper arm, lower arm and rear wall, then uniform illumination is achieved, but the device complexity increases

Engineering Contradiction:
Improveuniform illuminationVSAvoidhousing structure complexity
Core Design Contradiction:
Illumination intensityVSDevice complexity

Solution Approach 1:

Different LED sources are positioned at specific locations (upper arm, lower arm, rear wall) to address local illumination needs. Each LED group targets specific areas to create uniform overall illumination, with the housing structure optimized to distribute light evenly across the shelf surface while maintaining a relatively simple integrated design.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

Multiple LED sources and their mounting structures are merged into a single integrated housing unit. The upper arm, lower arm, and rear wall form a unified structure that houses all LED components, simplifying installation and maintenance while achieving uniform illumination through the coordinated arrangement of multiple LEDs within the combined housing.

Inventive Principle:
Principle #5Merging (Combining)

AI summary

Light source configured to be mounted on a shelf, preferably a glass or acrylic shelf. The light source comprising a housing (1) having an upper arm (2), a lower arm (3) and a rear wall (4), each having a cavity (5, 6, 7) for fixing a printed circuit board (8, 9, 10), and an aperture (11, 12, 13) for transmission of light emitted by a LED source (14, 15, 16). The rear wall (4) joins the upper arm (2) and the lower arm (3) at their proximal ends (2p, 3p), respectively. A distance (Dp) between these two proximal ends (2p, 3p) is greater than a distance (Dd) between distal ends (2d, 3d) of the upper arm (2) and the lower arm (3), respectively. At least one LED source (14, 15, 16) is mounted in the upper arm (2) and/or the lower arm (3), and/or the rear wall (4).
