Projector with Segmented Enclosures for Ceiling Mounting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector installation methods, such as hanging from a ceiling, are cumbersome and do not allow for easy placement behind a ceiling or in other locations, as they require heavy enclosures that complicate the installation process.
Innovation Solution
A projector design with separate enclosures for the projection and power supply sections, where the power supply enclosure is fixed to a support member, allowing the projection enclosure to be lightweight and easily installed on a ceiling or partitioning surface, with adjustable positioning to accommodate different environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the projector is installed as a single integrated unit hanging from the ceiling, then the installation structure is simple, but the weight is large and the installation process becomes cumbersome
Solution Approach 1:
The projector is divided into two separate enclosures: a first enclosure containing the projection section and a second enclosure containing the power supply section. The second enclosure is fixed to the ceiling while the first enclosure is suspended from it, allowing the heavy power supply to be anchored independently while keeping the projection unit lighter and easier to install and position.
2Reliability
If the projector enclosure is made heavy to ensure stability, then the installation is reliable, but it becomes difficult to install behind the ceiling
Solution Approach 1:
By separating the projector into two enclosures with different functions, the heavy power supply section can be securely anchored to the ceiling structure for stability, while the lighter projection section can be easily suspended and positioned. This segmentation allows each part to be optimized for its specific installation requirements.
Solution Approach 2:
The second enclosure acts as an intermediary between the ceiling structure and the first enclosure. It provides a stable mounting point on the ceiling and simultaneously supports the first enclosure through suspension, enabling both stability and ease of installation.
3Ease of operation
If the projection enclosure is made lightweight for easy installation, then it can be readily mounted on the ceiling, but it may compromise structural strength
Solution Approach 1:
The structural strength requirement is transferred to the second enclosure which contains the heavy power supply and is directly fixed to the ceiling. The first enclosure, which is lightweight and suspended, only needs to support its own weight and the projection components, reducing its structural strength requirements while maintaining overall system integrity.
Solution Approach 2:
The second enclosure serves as a structural intermediary that bears the main load on the ceiling. It provides strong mounting points and supports the first enclosure through suspension mechanisms, allowing the first enclosure to be lightweight without compromising the overall structural strength of the installation.

AI summary
A projector including a projection section that projects image light, a power supply section that supplies the projection section with electric power, a first enclosure that accommodates the projection section, and a second enclosure that accommodates the power supply section, wherein the second enclosure is fixed to a ceiling joist receiver that serves as a support member that supports a ceiling plate that partitions a space into a living room space and a space behind a ceiling, and the first enclosure and the second enclosure are configured to be separate from each other.
