Solution Overview

Problem

Electronic displays in outdoor or high-temperature environments face cooling challenges, as ingesting ambient air can introduce dust and contaminants, leading to premature failures, and existing mounting systems are not optimized for large public installations.

Innovation Solution

A method for mounting an electronic display to a vertical surface using a hybrid rear cover and mounting bracket with a thermal plate and plenum system, where external air is forced through a channel to extract heat and prevent dust entry, utilizing hooks and rods for hanging and latches for secure attachment, and fans for airflow within a sealed plenum.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Temperature

If ambient air is ingested for cooling the display, then the display temperature is reduced, but dust and contaminants enter the display causing premature failures

Engineering Contradiction:
Improvedisplay temperatureVSAvoiddisplay reliability
Core Design Contradiction:
TemperatureVSReliability

Solution Approach 1:

A sealed plenum chamber is introduced as an intermediary between the ambient environment and the display's internal components. This plenum allows air to be drawn in for cooling purposes while preventing direct ingress of dust and contaminants into the display's sensitive electronic components. The plenum acts as a buffer zone that mediates the cooling function while protecting against contamination.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The mounting system is segmented into distinct functional zones: a sealed plenum chamber for air intake and cooling, a protected internal cavity for housing electronic components, and a sealed interface between them. This segmentation allows the cooling function to be separated from the protected internal environment, enabling air flow for temperature reduction while maintaining reliability by preventing contaminant entry.

Inventive Principle:
Principle #1Segmentation

2Stability of the object's composition

If a secure mounting system is used for large displays in public areas, then the display installation stability is improved, but the installation complexity increases

Engineering Contradiction:
Improveinstallation stabilityVSAvoidmounting system complexity
Core Design Contradiction:
Stability of the object's compositionVSDevice complexity

Solution Approach 1:

The mounting bracket and rear cover are merged into a single integrated hybrid structure. This combination eliminates the need for separate mounting brackets and covers, simplifying the overall assembly while providing both secure wall mounting capabilities and protected housing for internal components. The integrated design reduces the number of parts and assembly steps while maintaining installation stability.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The hybrid rear cover and mounting bracket serves multiple functions simultaneously: it provides structural support for wall mounting, houses and protects internal electronic components, manages airflow through the plenum system, and secures the display panel. This multi-functionality reduces the need for separate specialized components, simplifying the overall mounting system while ensuring installation stability.

Inventive Principle:
Principle #6Universality (Multi-functionality)
