Solution Overview

Problem

Large outdoor LED displays face challenges with heat management and weatherproofing, as traditional cabinet-based systems require air conditioning for cooling and are prone to damage from rain and weather, leading to increased costs and maintenance complexities.

Innovation Solution

A modular multi-panel display system with hermetically sealed LED panels that use a mechanical support structure without cabinets, featuring a heat sink for passive cooling and an IP67 rating for waterproofing, allowing for easy installation and maintenance, and enabling the display of high-resolution images without the need for air conditioning or heating units.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional cabinet-based systems are used for outdoor LED displays, then the display structure is protected from weather, but the system requires air conditioning for cooling and is prone to damage from rain and weather, leading to increased costs and maintenance complexities

Engineering Contradiction:
Improveweather resistanceVSAvoidsystem complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The display system is divided into modular LED panels that can be independently assembled and configured. Each panel is a self-contained unit with integrated cooling and weatherproofing features, eliminating the need for complex centralized cabinet systems and air conditioning infrastructure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The LED panels incorporate passive cooling features and hermetic sealing that enable them to operate independently in outdoor environments without requiring external air conditioning units or complex weather protection systems. The panels self-regulate their thermal management through design features like heat sinks and convection channels.

Inventive Principle:
Principle #25Self-service

2Temperature

If air conditioning units are installed for cooling LED displays, then the display can operate in various weather conditions, but the operational costs increase and the system becomes more complex

Engineering Contradiction:
Improvecooling capabilityVSAvoidenergy consumption
Core Design Contradiction:
TemperatureVSUse of energy by stationary object

Solution Approach 1:

The active mechanical cooling system (air conditioning units) is replaced with passive thermal management features integrated into the LED panel structure, including heat sinks, convection channels, and thermally conductive materials that dissipate heat without requiring external power sources.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The LED panels self-manage their thermal dissipation through built-in passive cooling features, eliminating the need for externally powered air conditioning systems and reducing overall energy consumption of the display system.

Inventive Principle:
Principle #25Self-service

3Reliability

If cabinet-based systems are used to protect LED displays from weather, then the components are protected, but the system requires more materials and becomes heavier

Engineering Contradiction:
Improveweather protectionVSAvoiddisplay weight
Core Design Contradiction:
ReliabilityVSWeight of stationary object

Solution Approach 1:

The LED panels utilize thin, lightweight protective coatings and sealed enclosures that provide weatherproofing without the bulk and weight of traditional cabinet structures. The protective features are integrated directly into the panel housing rather than adding separate protective enclosures.

Inventive Principle:
Principle #30Flexible shells and thin films

4Strength

If traditional cabinet-based systems are used, then the display structure is robust, but installation and maintenance become more difficult and time-consuming

Engineering Contradiction:
Improvestructural strengthVSAvoidinstallation ease
Core Design Contradiction:
StrengthVSEase of operation

Solution Approach 1:

The display system is divided into modular LED panels that can be independently handled, transported, and installed. This segmentation allows for easier installation and maintenance compared to large monolithic cabinet systems, as individual panels can be replaced or serviced without affecting the entire display structure.

Inventive Principle:
Principle #1Segmentation
