Display Assembly Unobstructed Zone Framework
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital out-of-home (DOOH) advertising units with monolithic structures obstruct airflow, visibility, and radio signal transmission, posing challenges for pedestrian safety, structural integrity, and thermal management.
Innovation Solution
The design features a framework with unobstructed zones, where electronic displays are mounted in an elevated position, allowing for airflow and visibility while wiring and components are routed within or along framework members, and additional unobstructed areas are created using support members, maintaining structural integrity and shielding sensitive components from harsh weather and vandalism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a monolithic structure is used for DOOH advertising units, then structural integrity and seamless appearance are improved, but airflow obstruction and visibility blockage worsen
Solution Approach 1:
The monolithic structure is segmented into modular components including side assemblies, framework members, and unobstructed zones. This allows the structure to maintain structural integrity through proper connection of segments while creating openings for airflow and visibility without compromising overall strength
Solution Approach 2:
Different regions of the structure are assigned different qualities: solid enclosed sections provide structural support and protection, while unobstructed zones provide airflow and visibility. This local differentiation resolves the contradiction by allowing both strong construction and open areas to coexist in appropriate locations
2Ease of operation
If electronic displays are positioned at elevated height, then ergonomic viewing and regulatory compliance are improved, but structural complexity and wiring complexity worsen
Solution Approach 1:
The framework utilizes vertical dimension effectively by elevating displays to optimal viewing height while maintaining structural support through vertical members. This dimensional approach allows ergonomic positioning without proportionally increasing overall structural complexity
Solution Approach 2:
Framework members are designed to serve multiple functions: providing structural support, routing wiring, and defining unobstructed zones. This multi-functionality reduces overall complexity by consolidating multiple requirements into single structural elements
3Object-affected harmful factors
If unobstructed zones are created for airflow and visibility, then pedestrian safety and thermal management are improved, but protection of electronic components from weather and vandalism worsens
Solution Approach 1:
The structure is divided into protected enclosed sections for electronic components and unobstructed open zones for airflow and visibility. This segmentation allows components to be shielded from weather and vandalism while maintaining open areas for safety and thermal management functions
Solution Approach 2:
Framework members and cladding serve as intermediary elements that separate protected component areas from exposed unobstructed zones. These intermediaries provide physical protection for electronics while allowing the unobstructed zones to fulfill their safety and airflow functions

AI summary
Display assemblies are provided. One or more electronic display subassemblies are mounted to a framework at an elevated position. An unobstructed zone is located below each of the electronic display subassemblies and within said framework. Wiring and electronic components may extend along some of the framework and may be covered by cladding.
