Integrated Dome Screen Projector Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional dome screen projection systems require additional steel support structures and catwalks, leading to integration uncertainties, increased space occupation, longer installation times, and safety hazards during maintenance.
Innovation Solution
A dome screen projection system design that integrates projectors directly onto the dome screen unit, eliminating the need for extra steel support structures and catwalks, using platforms and ladders for access, and optimizing projector placement for improved image fusion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If additional steel support structures and catwalks are provided, then projectors can be properly positioned and supported, but device complexity and space occupation increase
Solution Approach 1:
The patent merges the projector support function directly into the dome screen structure by integrating side walls that extend upward to support projectors. This eliminates the need for separate steel support structures and catwalks, reducing device complexity while maintaining reliable projector positioning through the integrated structural design.
2Reliability
If additional steel support structures and catwalks are provided, then projectors can be properly positioned, but installation time increases
Solution Approach 1:
By combining the support structure and projector mounting into a single integrated dome screen assembly, the patent eliminates multiple installation steps required for separate steel structures and catwalks. The projectors can be directly mounted to the integrated side walls, significantly reducing installation time while ensuring proper positioning.
3Ease of operation
If catwalks are provided for projector placement, then projectors can be accessed for maintenance, but safety hazards increase
Solution Approach 1:
The patent integrates projector support directly into the dome screen structure, allowing projectors to be positioned at the sides of the dome where they are naturally accessible. This eliminates the need for dangerous catwalks while maintaining ease of operation, as projectors can be serviced from ground level or through simple access points in the integrated structure.
4Ease of manufacture
If separate structures for dome screen and catwalk are used, then each component can be independently constructed, but coordination difficulty increases
Solution Approach 1:
The patent merges the dome screen and projector support into a single integrated structure with side walls that serve both functions. This eliminates the need for coordination between separate dome screen and catwalk designs, simplifying the overall design process while maintaining manufacturing ease through a unified structural approach.

AI summary
A dome screen projection system includes a dome screen unit and two sets of projectors. The dome screen unit includes a top side, two opposite lateral sides extending downward from two opposite ends of the top side, and a curved projection surface extending downwardly from the top side between the opposite lateral sides. Each of the two sets of projectors are disposed on the top side proximally to one of the lateral sides. The two sets of projectors are directed toward the curved projection surface.
