Projector Case Duct Cover Orientation Flexibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional projector cases restrict the change in projection direction due to fixed attachment directions of the panning direction rotation element and entrance suppression cover, limiting flexibility in setting the projector for different projection scenarios such as floor, horizontal, and ceiling projections.
Innovation Solution
A projector case design featuring intake/exhaust ports with multiple attachment target holes on their circumference, allowing duct covers to be attached in various orientations, and connection openings that communicate with external openings, enabling flexible attachment and orientation of duct covers to accommodate different projection settings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the panning direction rotation element and entrance suppression cover are fixed in specific attachment directions, then the structure is simple and easy to manufacture, but the flexibility in setting the projector for different projection scenarios is limited
Solution Approach 1:
The attachment stay is designed with a universal structure that can be attached to the case at multiple different directions and angles. The stay includes a rotation element that allows it to be positioned in various orientations, enabling the projector to be mounted for different projection scenarios (ceiling, wall, floor projection) without requiring multiple specialized attachment mechanisms.
Solution Approach 2:
The attachment stay incorporates a panning direction rotation element that allows dynamic adjustment of the attachment angle. This rotation mechanism enables the stay to change its orientation relative to the case, providing adaptability for different projection directions while maintaining a single unified attachment structure.
2Adaptability or versatility
If the duct cover is fixed in a single orientation, then the manufacturing and assembly process is simpler, but the ability to accommodate different projection settings (floor, horizontal, ceiling projections) is restricted
Solution Approach 1:
The duct cover is designed with multiple attachment holes arranged in different orientations around its perimeter. This universal attachment configuration allows the duct cover to be mounted in various orientations (0°, 90°, 180°, 270°) to accommodate different projection settings. The intake/exhaust ports are also positioned to work effectively in any of these orientations.
Solution Approach 2:
The duct cover features asymmetric placement of attachment holes and intake/exhaust ports that are strategically positioned to provide functional attachment points in multiple directions. This asymmetric design enables flexible orientation while maintaining a relatively simple single-piece cover structure.
3Adaptability or versatility
If multiple attachment target holes are provided on the circumference of intake/exhaust ports, then the duct cover can be attached in multiple orientations for versatile projection settings, but the structural complexity of the case increases
Solution Approach 1:
The intake/exhaust ports are designed with multiple attachment target holes positioned at different angles around their circumference. These ports serve multiple functions: they provide structural attachment points for the duct cover in various orientations, maintain proper airflow paths regardless of duct cover orientation, and integrate seamlessly into the case structure without requiring separate mounting mechanisms.
