Solution Overview

Problem

Large-area display apparatuses face cooling efficiency challenges, particularly when installed outdoors, as they generate high temperatures due to backlight assemblies, leading to accelerated degradation and requiring numerous fans that can cause malfunctions and noise.

Innovation Solution

A display apparatus with a cooling device that includes a flux augmentation guide with a first and second fluid passage, enhancing air flux through a fan, which is obliquely disposed to discharge air parallel or at an angle towards the display, reducing the need for multiple fans and noise.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If multiple fans are used to cool large-area displays, then cooling coverage is improved, but device complexity and noise increase

Engineering Contradiction:

Improvedisplay temperatureVSAvoidfan quantity

Core Design Contradiction:

TemperatureVSDevice complexity

Solution Approach 1:

The cooling system is segmented into multiple fluid passages (first fluid passage and second fluid passage) that distribute cooling air to different regions of the display. The second fluid passage introduces air from the periphery of the first fluid passage, creating segmented cooling zones that collectively cover the entire large-area display without requiring multiple physical fans.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The flux augmentation guide acts as an intermediary component that amplifies the cooling air flux generated by a single fan. By incorporating fluid passages and peripheral air introduction, the guide mediates between the fan's limited output and the large display's cooling requirements, multiplying the effective cooling coverage through fluid dynamics rather than mechanical multiplication.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If multiple fans are deployed for large-area cooling, then cooling efficiency is improved, but noise and malfunction risk increase

Engineering Contradiction:

Improvecooling efficiencyVSAvoidnoise

Core Design Contradiction:

ProductivityVSObject-generated harmful factors

Solution Approach 1:

The flux augmentation guide serves as a mediator that enhances cooling efficiency through fluid passage design rather than mechanical means. The guide's structure with first and second fluid passages creates efficient air flow patterns that cool large areas using minimal fan power, thereby reducing noise generation while maintaining high cooling productivity.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The invention replaces the mechanical approach of using multiple fans with a fluid dynamics-based flux augmentation guide. Instead of mechanically adding more fan units, the system uses carefully designed fluid passages that leverage air flow physics to multiply cooling effectiveness, eliminating the noise and complexity associated with multiple mechanical fan assemblies.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Temperature

If fans are used to cool large-area displays, then temperature control is improved, but reliability decreases due to malfunction risk

Engineering Contradiction:

Improvedisplay temperatureVSAvoidfan reliability

Core Design Contradiction:

TemperatureVSReliability

Solution Approach 1:

The cooling air flow is segmented into multiple controlled pathways within the flux augmentation guide. The first fluid passage carries primary cooling air while the second fluid passage introduces peripheral air, creating redundant cooling pathways that ensure reliable temperature control even if one pathway is partially blocked or less efficient.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The flux augmentation guide acts as a reliable intermediary that passively manages air distribution through its fluid passage structure. This passive fluidic design has no moving parts within the guide itself, eliminating the risk of mechanical failure in the air distribution system while ensuring consistent temperature control across the large display area.

Inventive Principle:

Principle #24Intermediary (Mediator)
