Solution Overview

Problem

Existing point-like effect lighting systems require one-to-one correspondence with light sources, leading to high production costs and times, and often necessitate panel perforation for source placement, lacking optimization in both cost and efficiency.

Innovation Solution

A production process involving extrusion or injection molding with a nailed scoring roller to create zones on the panel surface for light diffusion, eliminating the need for individual light element application and reducing thickness to achieve luminous effects without perforation, using LED or fluorescent modules.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Illumination intensity

If one-to-one correspondence with light sources is used, then luminous effect is achieved, but production costs and times increase

Engineering Contradiction:

Improveluminous effectVSAvoidproduction time

Core Design Contradiction:

Illumination intensityVSProductivity

Solution Approach 1:

The patent merges multiple light sources into a single continuous light strip that runs along the panel. Instead of placing individual light sources at each point, a continuous LED strip provides illumination that, when viewed from the front, creates the perception of multiple luminous points through the patterned translucent zones, significantly reducing production time and complexity.

Inventive Principle:

Principle #5Merging (Combining)

Solution Approach 2:

The patent segments the panel surface into multiple translucent zones with different light transmission properties. These zones are created by varying the thickness or material properties of the panel in specific patterns, allowing a single continuous light source to create differentiated luminous effects when viewed from the front.

Inventive Principle:

Principle #1Segmentation

2Ease of manufacture

If panel perforation is performed for light source placement, then light sources can be positioned, but manufacturing complexity increases

Engineering Contradiction:

Improvelight source placementVSAvoidmanufacturing process

Core Design Contradiction:

Ease of manufactureVSDevice complexity

Solution Approach 1:

Instead of creating holes in the panel to insert light sources, the patent inverts the approach by placing the light sources on the rear surface and using the panel's translucent zones to project light forward. This eliminates the need for perforation and complex assembly operations.

Inventive Principle:

Principle #13The other way round (Inversion)

Solution Approach 2:

The panel structure itself serves the dual function of both structural support and light diffusion. The translucent zones are integrated into the panel material, eliminating the need for separate light source mounting components and simplifying the manufacturing process.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If multiple individual light elements are applied, then precise luminous control is achieved, but production costs increase

Engineering Contradiction:

Improveluminous controlVSAvoidnumber of light sources

Core Design Contradiction:

Ease of operationVSQuantity of substance

Solution Approach 1:

The single continuous LED strip performs multiple functions: it provides continuous illumination, works in conjunction with the patterned translucent zones to create point-like effects, and can be controlled to produce various luminous patterns. This universal light source replaces numerous individual light elements.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent changes the optical parameters of the panel by creating zones with different light transmission properties (different thicknesses or materials). This allows a single light source to create varied luminous effects by modulating light transmission rather than requiring multiple light sources with different intensities.

Inventive Principle:

Principle #35Parameter changes
