Movable LED Lighting Elements for Wind-Resistant Displays
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Outdoor LED wall systems face a trade-off between high wind resistance and resolution, as mesh systems with openings for wind resistance have reduced LED density and resolution, while solid systems without openings provide higher resolution but lack wind resistance.
Innovation Solution
A display device with movable lighting elements that can be positioned to either fill openings for high resolution or retract to allow wind flow, controlled by a unit responsive to weather conditions, allowing a dual solid or mesh structure selection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mesh LED wall systems with openings are used to improve wind resistance, then wind resistance is improved, but resolution is reduced
Solution Approach 1:
The patent applies the dynamics principle by making the lighting elements movable rather than fixed. The lighting elements can dynamically change position between a first position (filling openings for high resolution) and a second position (retracting to create openings for wind resistance). This transforms a static structure into a dynamic one that can adapt to different environmental conditions, resolving the contradiction between wind resistance and resolution by allowing the system to optimize for each condition separately.
2Manufacturing precision
If solid LED wall systems without openings are used to improve resolution, then resolution is improved, but wind resistance is reduced
Solution Approach 1:
The patent applies the dynamics principle by making the lighting elements movable rather than fixed. The lighting elements can dynamically change position between a first position (filling openings for high resolution) and a second position (retracting to create openings for wind resistance). This transforms a static structure into a dynamic one that can adapt to different environmental conditions, resolving the contradiction between wind resistance and resolution by allowing the system to optimize for each condition separately.
3Adaptability or versatility
If movable lighting elements are added to enable position change, then adaptability is improved, but device complexity is increased
Solution Approach 1:
The patent applies the universality principle by designing lighting elements that serve multiple functions: they provide illumination and simultaneously act as movable structural components that define the openings. The same lighting element can fill openings to create a solid structure for high resolution or retract to create openings for wind resistance. This multi-functionality reduces the need for separate mechanical structures, thereby limiting the increase in device complexity while achieving adaptability.
