Solution Overview

Problem

Current light-emitting devices face challenges in improving performance and quality, particularly in the arrangement and shielding of light-emitting modules to enhance efficiency and reduce interference.

Innovation Solution

The design incorporates a light-emitting device with modules spaced apart by a gap, where a light-shielding structure partially overlaps this gap, and includes a substrate pattern that overlaps with the modules, along with a connecting element between adjacent electronic elements, facilitating improved electrical connections and reduced light interference.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If light-emitting modules are arranged closely to increase density, then productivity and area utilization are improved, but light interference between adjacent modules increases

Engineering Contradiction:

Improvemodule densityVSAvoidlight interference

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

A light-shielding structure is introduced as an intermediary element between adjacent light-emitting modules. This structure includes a first portion extending over a gap between modules and a second portion extending over at least one of the modules, creating a barrier that blocks light interference while maintaining close module arrangement for high density

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If a light-shielding structure is introduced to reduce light interference, then light interference is minimized, but device complexity increases

Engineering Contradiction:

Improvelight interferenceVSAvoidstructure complexity

Core Design Contradiction:

Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The light-shielding structure is segmented into a first portion and a second portion with different functions. The first portion addresses light blocking between modules, while the second portion provides additional shielding over specific modules. This segmentation allows targeted protection without requiring a completely complex shielding system

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The light-shielding structure partially overlaps the gap between modules rather than completely sealing it. This partial action is sufficient to block harmful light interference while avoiding the complexity of a complete enclosure, achieving the necessary protection with minimal structural complexity

Inventive Principle:

Principle #16Partial or excessive action

3Object-affected harmful factors

If modules are spaced apart by gaps to reduce interference, then light interference is reduced, but area utilization and productivity decrease

Engineering Contradiction:

Improvelight interferenceVSAvoidarea utilization

Core Design Contradiction:

Object-affected harmful factorsVSProductivity

Solution Approach 1:

Instead of solving the light interference problem by increasing horizontal spacing, the light-shielding structure extends in a vertical dimension over the gap between modules. This allows modules to remain closely spaced in the horizontal plane for high density while the vertical shielding portion blocks light interference

Inventive Principle:

Principle #17Another dimension (Dimensionality change)
