Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing large LED displays for outdoor environments require portable and lightweight structures that can be easily erected and dismantled, while supporting the weight of the display without destabilizing the framework, and preventing overheating.
Innovation Solution
An air-supported framework with upper, lower, and side segments, additional support structures that bend away from the display plane, and vent seals to maintain high air pressure, along with a back covering for ventilation and light blocking.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If traditional aluminum or steel trusses are used to support LED displays, then structural strength and stability are improved, but portability and ease of erection are worsened
Solution Approach 1:
The patent uses an air-supported framework where inflated air beams provide structural support. The air beams are inflated through vents connected to blowers, creating a pneumatic structure that replaces traditional rigid trusses. This allows the framework to be lightweight and portable when deflated, yet provide sufficient structural strength when inflated, directly resolving the contradiction between strength and portability.
Solution Approach 2:
The framework employs flexible air beams made from thin-walled tubes that can be inflated to provide structural support. These flexible elements can be easily stored and transported in a deflated state, then quickly erected by inflation, solving the contradiction between ease of operation and structural strength.
2Ease of operation
If the framework is made lightweight and portable, then ease of transport is improved, but ability to support heavy LED displays is worsened
Solution Approach 1:
The framework transitions from a static rigid structure to a dynamic pneumatic structure. The air beams can be inflated to the required pressure to support the LED display load, then deflated for easy transport. This dynamic capability allows the same structure to provide high load bearing capacity during operation while maintaining ease of transport during storage and relocation.
Solution Approach 2:
The internal air pressure within the air beams provides an outward force that counteracts the gravitational load of the LED display. The pressurized air acts as a counterbalancing force, allowing the lightweight framework to support heavy displays without requiring heavy structural materials.
3Stability of the object's composition
If vent seals are added to maintain higher air pressure, then structural stability is improved, but device complexity is worsened
Solution Approach 1:
The framework is divided into multiple air beams with individual vent seals at each end. This segmentation allows each beam to be independently sealed and pressurized, maintaining structural stability while keeping each individual component relatively simple. The modular approach distributes the sealing requirements across multiple simple components rather than requiring a single complex sealing system.

AI summary
An air supported frame is provided for supporting a large LED display wherein the frame includes upper, lower and side segments and has a front portion and a rear portion and the LED display is positioned when in use within the frame substantially midway between the front portion and rear portion. Further, an additional support structure may be attached to the upper and lower segments of the air supported frame wherein the additional support structure bends, curves, or angles away from the plane of the display so as to provide support to the upper segment without interfering with the display. In addition, the air supported frame may include vent seals that allow greater air pressure to be held within the air supported frame.
