Video Display Truss with Integrated Air Channels
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional video display systems require large installation footprints due to support structures, audio and video equipment, and separate cooling systems, which occupy valuable space and pose challenges in aesthetics and installation flexibility, especially in retail environments where they can extend over 36 inches in depth and suffer from decreased cooling efficiency due to turbulent airflow.
Innovation Solution
A video display system featuring a truss structure with air channels and apertures to direct airflow efficiently, a diffuser to discharge air upwardly across the screen, and a compact design that positions the video display cantilevered forward of the truss, reducing the overall footprint and enhancing aesthetics while improving cooling efficiency by minimizing airflow diversion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If conventional support structures and separate cooling systems are used, then structural stability is ensured, but the installation footprint increases significantly
Solution Approach 1:
The patent combines the support structure and cooling system into a single integrated truss assembly. The truss contains internal air channels that serve as cooling pathways, eliminating the need for separate cooling equipment and reducing the overall installation footprint while maintaining both structural support and thermal management functions
Solution Approach 2:
The truss structure performs multiple functions simultaneously: it provides mechanical support for the video display, serves as a cooling system through integrated air channels, and acts as a mounting framework. This multi-functionality reduces the number of separate components needed and minimizes the space required for installation
2Area of stationary object
If separate cooling systems are used, then cooling capacity is sufficient, but the system occupies valuable space
Solution Approach 1:
The cooling air channels are nested within the truss structure itself. The air channels are positioned inside the truss beams, utilizing the existing structural space for dual purposes: structural support and thermal management. This nesting eliminates the need for external cooling equipment and reduces space occupation
3Temperature
If conventional cooling systems are used, then heat dissipation is achieved, but turbulent airflow decreases cooling efficiency
Solution Approach 1:
The truss structure incorporates localized features such as apertures and diffusers at specific positions to control airflow characteristics. These localized elements create laminar flow zones where needed, directing cool air efficiently across the display surface and improving heat dissipation without requiring complex system-wide airflow control
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution achieves a compact, aesthetically pleasing, and efficient cooling system that reduces the video display system's footprint, maintains effective heat dissipation, and enhances user comfort by directing airflow away from individuals, thus addressing the limitations of conventional systems.
Implementation Method 1
an air channel within at least one of the first or second beams... configured to discharge air along the rear of the video display modules
Implementation Method 2
a diffuser coupled to the supply air duct and disposed below the video display and configured to discharge air upwardly across the screen of the video display
