Problem
Existing portable projection and display systems are complex to set up, take down, store, and transport, and lack stability and adjustability, making them less desirable for easy use and versatility.
Innovation Solution
A portable projection and display system featuring a foldable frame assembly with trusses, adjustable boom, and counterweight mechanism that allows for easy setup, adjustment, and stability, including hinged vertical support members, latching hitch pins, and a counterweight bar for projector alignment and stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If existing portable projection and display systems are used, then projection and display functions are provided, but setup and takedown processes are complex and time-consuming
Solution Approach 1:
The display system is divided into separate modular components including a display frame assembly, projector support assembly, and screen assembly. Each component can be independently assembled, positioned, and disassembled, significantly reducing setup and takedown time while maintaining system functionality.
Solution Approach 2:
The projector support assembly incorporates an adjustable boom with movable sections that can be extended, retracted, and repositioned. This dynamic structure allows quick adaptation to different projection distances and screen sizes without requiring complete system disassembly or complex reconfiguration.
2Reliability
If existing portable projection and display systems are used, then projection functions are provided, but stability and adjustability are insufficient
Solution Approach 1:
The boom assembly includes adjustable sections with locking mechanisms that provide both stability when locked in position and adjustability when reconfigured. This allows the system to maintain reliability during operation while offering versatility for different projection scenarios.
Solution Approach 2:
The display frame assembly serves multiple functions: supporting the screen, providing structural stability, and offering mounting points for the projector support assembly. This multi-functional design enhances both stability and adaptability without requiring additional components.
3Ease of operation
If existing portable projection and display systems are used, then projection functions are provided, but transportation and storage are difficult
Solution Approach 1:
The system is divided into discrete assemblies (display frame, projector support, screen) that can be separated for compact storage and easy transportation. Each segment is self-contained and can be handled independently, reducing the complexity of logistics and storage requirements.
Solution Approach 2:
The collapsible boom assembly with hinged sections allows the projector support structure to be folded into a compact configuration for transportation and storage, while maintaining full functionality when deployed. This dynamic folding mechanism reduces spatial requirements without sacrificing structural capability.

AI summary
A portable projection and display system can include a frame assembly having one or more folding trusses, a counterweight bar arranged on a rearward bottom portion of the frame to help provide a stable base, and an adjustable boom. A projector can be mounted on one end of an adjustable boom. The boom can adjust a distance between the projector and the display screen. The boom can be mounted to the frame with a hinged connection to permit it to act as a lever to raise and lower the projector. An adjustable boom bar can be attached to an end of the boom opposite the projector such that adjustment of the boom bar raises and lowers the projector via a lever action about a fulcrum.
