Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing shading devices for LED displays are difficult to remove and repair due to their firm attachment using hard connections, which leads to irregular mechanical fitting and non-uniform display performance.

Innovation Solution

A shading device is mechanically connected to an LED display system using a plurality of soft connections, such as fixing elements like cavities or slots on the light source unit, allowing for easy attachment and detachment without damaging the system, and distributing the load evenly to prevent deformation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If the shading device is firmly connected to the LED PCB using hard connections (clips), then the mechanical attachment strength is improved, but the ease of repair and removability deteriorates

Engineering Contradiction:

Improvemechanical attachment strengthVSAvoidremovability for repair

Core Design Contradiction:

StrengthVSEase of repair

Solution Approach 1:

The shading device is divided into multiple independent connection points distributed across its surface. Each connection point provides individual mechanical attachment to the LED PCB, allowing the shading device to be securely fixed while maintaining uniform load distribution that prevents damage during removal and reattachment operations.

Inventive Principle:

Principle #1Segmentation

2Strength

If hard connections (clips) are used to firmly attach the shading device, then the mechanical fixation is improved, but the device complexity and manufacturing difficulty increase

Engineering Contradiction:

Improvemechanical fixationVSAvoidcomplexity of connection structure

Core Design Contradiction:

StrengthVSDevice complexity

Solution Approach 1:

The LED PCB structure itself serves as the fixing mechanism for the shading device. The existing LED package bodies and PCB features are utilized as attachment points, eliminating the need for separate complex clipping mechanisms. This self-service approach simplifies the overall device structure while providing robust mechanical fixation.

Inventive Principle:

Principle #25Self-service

3Ease of manufacture

If a few hard connections (clips) are used to attach the shading device, then the ease of manufacture is improved, but the uniformity of mechanical fitting deteriorates

Engineering Contradiction:

Improvesimplicity of attachment methodVSAvoiduniformity of mechanical fitting

Core Design Contradiction:

Ease of manufactureVSManufacturing precision

Solution Approach 1:

The connection system is segmented into numerous distributed attachment points across the shading device surface. This segmentation enables uniform load distribution and consistent mechanical fitting across the entire display area, achieving high manufacturing precision through multiple simple connection points rather than fewer complex ones.

Inventive Principle:

Principle #1Segmentation
