Projector Lamp Access via Sliding Tray and Modified Filter Door
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In image projection lighting devices, the existing LX650 projector device requires complete removal from the lamp housing and opening of the filter door to access and replace the projector lamp, which is inconvenient and prone to handling damage.
Innovation Solution
A modified LX650 projector device allows the lamp door to be opened without opening the filter door, utilizing a tray device that enables the projector to be partially slid out for lamp access, eliminating the need for complete removal and minimizing handling risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the projector device is completely removed from the lamp housing to access the lamp door, then the lamp can be accessed and replaced, but the operation becomes inconvenient and increases handling damage risk
Solution Approach 1:
The patent divides the access operation into segments: the projector device remains partially in the lamp housing while only the necessary portion (lamp door area) is made accessible. The filter door is segmented to allow independent access to the lamp door screw without requiring complete projector removal, thus maintaining reliability while improving operational ease.
Solution Approach 2:
The patent introduces an intermediary mechanism (modified filter door with opening or removable portion) that mediates between the closed filter door and the lamp door screw. This intermediary allows access to the lamp door screw without requiring complete projector removal, resolving the contradiction between ease of operation and handling safety.
2Ease of operation
If the filter door is opened to access the lamp door screw, then the lamp door can be opened, but the filter door opening is unnecessary and complicates the procedure
Solution Approach 1:
The patent extracts the lamp door screw from behind the filter door by providing an opening or removable portion in the filter door itself. This allows the lamp door screw to be accessed directly without opening the filter door, simplifying the access procedure and reducing operational complexity.
Solution Approach 2:
Instead of requiring access through the filter door (traditional approach), the patent inverts the approach by creating a direct access path through the filter door structure itself (opening or removable portion), allowing lamp door screw access without filter door removal. This reverses the traditional access sequence and simplifies the procedure.
3Productivity
If the projector device is designed with traditional access methods, then structural integrity is maintained, but lamp replacement becomes cumbersome and time-consuming
Solution Approach 1:
The patent segments the filter door structure to provide direct access to the lamp door screw while maintaining the overall structural integrity of the projector device. This segmentation allows rapid lamp replacement (improved productivity) without requiring complete projector removal, thus maintaining ease of operation.

AI summary
An image projection lighting device including a base housing, a yoke, a lamp housing, and a video projector located inside the lamp housing, is disclosed. The video projector includes a video projector housing. The video projector housing can be moved into a first position and a second position in relation to the lamp housing. The first position is a video projector operating position in which the video projector cannot be serviced. The video projector can be serviced in the second position. A projector lamp cannot be accessed in the first position but can be accessed in the second position.
