Recessed Projection Screen Housing With Independent Motor Assembly Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional recessed projection screen systems require the entire housing and screen motor assembly to be installed and removed from the ceiling simultaneously, making separate installation and servicing cumbersome and potentially damaging.
Innovation Solution
A projection screen system with a housing that can be installed recessed in a ceiling independently of the screen and motor assembly, which can be mounted and removed separately, using opposed mounting features and a method that includes installing the housing first and then mounting the screen and motor assembly within it.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the entire housing and screen motor assembly are installed simultaneously from the ceiling, then the structural integrity is maintained, but the installation and servicing become cumbersome and potentially damaging
Solution Approach 1:
The projection screen system is divided into two independent modules: a housing module and a screen motor assembly module. The housing can be installed recessed in the ceiling first, and the screen motor assembly can be mounted separately within the housing channel. This segmentation allows each component to be handled and installed independently, reducing installation complexity and potential damage while maintaining structural integrity.
2Ease of repair
If the entire system is removed from the ceiling for servicing, then complete access is achieved, but the ceiling structure is potentially damaged and installation time is increased
Solution Approach 1:
The screen motor assembly is designed as a separate removable module that can be extracted from the housing without removing the housing itself. The mounting features allow the screen motor assembly to be detached and reattached, enabling servicing of the motor and screen mechanism while leaving the ceiling-mounted housing in place, thus avoiding ceiling damage and reducing service time.
3Stability of the object's composition
If heavy components are installed simultaneously, then structural stability is maintained, but installation difficulty and safety risks increase
Solution Approach 1:
The heavy housing and screen motor assembly are separated into independent installation stages. First, the housing is installed recessed in the ceiling, establishing a stable structural base. Then, the screen motor assembly is mounted within the housing channel using mounting features. This staged approach distributes the weight and complexity across separate installation operations, improving safety and ease of operation while maintaining overall system stability.

AI summary
A projection screen system includes a housing defining a channel, a screen and motor assembly including a projection screen and a tubular motor, and first and second opposed mounting features configured to hold the screen and motor assembly in the channel of the housing. The housing is configured to be installed recessed in a ceiling and the screen and motor assembly is configured to be mounted in the housing of the installed housing such that the installation of the housing and the mounting of the screen and motor assembly are performed independently.
