Solution Overview

Problem

Conventional light panels are heavy, leading to increased stress on mounting means and surfaces, and they often suffer from non-uniform light intensity due to the lack of inherent stability and torsional rigidity in their front panels, which complicates mounting and installation, especially on fragile surfaces.

Innovation Solution

A self-supporting translucent light panel structure with cross-linking walls that separate the front and rear panels, incorporating a light scattering medium to achieve uniform light intensity and reduce weight, allowing for flexible design and mounting options using adhesive bonding, bolting, or snapping onto a carrier.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Stability of the object's composition

If heavy acrylic plastic panels are used to provide structural stability and torsional rigidity, then the front panel stability is improved, but the overall weight of the light panel increases

Engineering Contradiction:
Improvefront panel stabilityVSAvoidlight panel weight
Core Design Contradiction:
Stability of the object's compositionVSWeight of moving object

Solution Approach 1:

The patent combines a lightweight aluminum frame structure with a translucent plastic front panel to create a composite construction that provides the necessary structural stability and torsional rigidity without the weight penalty of heavy acrylic plastic panels. The aluminum frame acts as a supporting skeleton that stabilizes the inherently unstable plastic panel.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The light panel is divided into distinct functional components: a lightweight aluminum frame structure providing structural stability and a separate translucent plastic front panel providing the light transmission surface. This segmentation allows each component to be optimized independently - the frame for strength-to-weight ratio and the panel for translucency and light diffusion.

Inventive Principle:
Principle #1Segmentation

2Device complexity

If light sources are positioned internally in channels of a channeled plastic sheet, then the light panel structure is simplified, but the light intensity becomes non-uniform across the panel area

Engineering Contradiction:
Improvelight panel structureVSAvoidlight intensity uniformity
Core Design Contradiction:
Device complexityVSIllumination intensity

Solution Approach 1:

The patent introduces a light diffusing layer as an intermediary component between the light sources and the front panel. This diffusing layer scatters and redistributes the light uniformly across the entire front panel surface, eliminating the non-uniform intensity patterns that would result from direct internal channel lighting.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The light diffusing layer is strategically positioned only in the regions where light intensity needs to be equalized, allowing different parts of the light panel to have different optical properties - the channels provide structured light paths while the diffusing layer ensures uniform output across the viewing surface.

Inventive Principle:
Principle #3Local quality

3Strength

If the front panel is made from thick and heavy acrylic plastic to provide stability, then the structural rigidity is improved, but the mounting demands on surfaces and mounting means increase

Engineering Contradiction:
Improvestructural rigidityVSAvoidmounting load
Core Design Contradiction:
StrengthVSForce

Solution Approach 1:

The patent uses a composite construction combining an aluminum frame with a plastic front panel. The aluminum frame provides the necessary structural rigidity and strength to support the panel, while the plastic panel provides the light transmission function. This composite approach achieves the required structural performance with significantly reduced weight compared to solid thick acrylic plastic.

Inventive Principle:
Principle #40Composite materials

Solution Approach 2:

The lightweight aluminum frame structure acts as a counterbalancing support system that compensates for the inherent instability of thin plastic panels without requiring heavy counterweights or thick plastic sections. The frame's structural geometry and material properties provide the necessary rigidity with minimal weight.

Inventive Principle:
Principle #8Anti-weight (Counterweight)
