Projection Screen Bottom Rail Camera Integration
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projection screens often interfere with the placement of video cameras and controllers, leading to undesirable camera angles and 'dead spots' in presentation rooms due to the need to position these devices above, below, or to the side of the screen to avoid obstruction.
Innovation Solution
Integration of interactive devices such as cameras and controllers with the bottom rail of projection screens, allowing for communicative coupling via wireless or wired connections, ensuring they are not blocked by the screen and can be centrally positioned for effective coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the video camera is placed above, below, or to the side of the projection screen to avoid obstruction, then the camera is not blocked by the screen, but the camera angles become undesirable or portions of the room lack camera coverage
Solution Approach 1:
The patent combines the video camera with the projection screen assembly by mounting the camera on the screen housing or frame. This integration allows the camera to be positioned in proximity to the screen without requiring separate mounting locations above, below, or to the side, thereby achieving both complete room coverage and optimal camera angles simultaneously.
Solution Approach 2:
The patent positions the video camera in a different spatial dimension relative to the screen - specifically, mounting the camera on the screen assembly itself creates a new positioning dimension that allows the camera to capture the entire room including areas that would otherwise be obscured by traditional side or top mounting positions.
2Reliability
If the controller receiver is placed above, below, or to the side of the projection screen to avoid obstruction, then the receiver is not blocked by the screen, but dead spots are created where the controller is less than effective
Solution Approach 1:
The patent integrates the controller receiver with the projection screen assembly, mounting the receiver on the screen housing or frame. This combination eliminates the need for separate positioning above, below, or to the side of the screen, allowing the receiver to be centrally located and eliminate dead spots while maintaining unobstructed signal reception.
3Reliability
If interactive devices are placed separately from the projection screen, then the devices can be positioned to avoid obstruction, but the placement leads to dead spots and incomplete room coverage
Solution Approach 1:
The patent merges interactive devices such as video cameras and controller receivers with the projection screen assembly into a unified system. This integration allows the devices to be optimally positioned relative to the screen while maintaining complete room coverage and eliminating dead spots, thereby enhancing both functionality and adaptability.
Solution Approach 2:
The patent creates a multi-functional projection screen assembly that combines the projection screen with interactive devices. This universal assembly serves multiple purposes - projection display, video capture, and controller reception - all in one integrated unit, eliminating the need for separate device placement and maximizing room coverage.

AI summary
Systems and methods for more effectively locating cameras, controllers, and other interactive devices in conjunction with projection screens. A projection screen includes a screen presenting a surface suitable for projecting an image thereon, the screen having a bottom rail and an interactive device operably coupled to the bottom rail of the screen, the interactive device communicatively coupled to a communicating device. The interactive device may be a video camera, a sensor, or a controller.
