Projector Transparent Blocking Member for Safe Lamp Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing projector ceiling mounts do not provide a safe mechanism for users to replace lamps without exposing themselves to potential harm from exploding lamp fragments, as the interior cannot be inspected before opening the cover, risking injury from falling debris.
Innovation Solution
A projector design featuring a transparent blocking member on the casing's opening allows safe inspection and replacement of the light source module by isolating and adhering any fragments, ensuring user safety and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the cover of the projector is opened to replace the lamp, then the user can directly replace the lamp without removing the projector, but the user may be injured by lamp fragments dropping into their eyes or on their body
Solution Approach 1:
A transparent blocking member is introduced as an intermediary between the user and the lamp fragments. This blocking member allows the user to inspect the lamp condition and replace the lamp while preventing lamp fragments from reaching the user, thus resolving the contradiction between ease of operation and safety.
Solution Approach 2:
The blocking member is made transparent rather than opaque, providing local quality that allows visual inspection while still blocking harmful fragments. This resolves the contradiction by maintaining visibility for convenience while providing protection against injury.
2Loss of information
If the cover of the projector is opened to check the lamp condition, then the user can determine the reason for lamp failure, but the user is exposed to potential harm from exploding lamp fragments
Solution Approach 1:
The transparent blocking member serves as a mediator that enables the user to obtain information about the lamp condition (whether it has exploded or aged) while simultaneously protecting the user from lamp fragments. This resolves the contradiction between information access and safety.
Solution Approach 2:
The transparent blocking member allows visual inspection of the lamp condition through color or clarity changes that indicate lamp status, enabling information gathering without physical exposure to harmful fragments.
3Device complexity
If no blocking member is installed, then the projector structure remains simple, but the user cannot safely inspect the lamp condition without opening the cover
Solution Approach 1:
The blocking member is made transparent rather than opaque, adding minimal structural complexity while enabling safe inspection. The transparency allows the blocking member to be visually unobtrusive while providing essential safety functionality.
Solution Approach 2:
The blocking member can be implemented as a thin transparent film or shell that covers the opening, adding minimal structural complexity while providing the necessary safety function for lamp inspection.

AI summary
A projector being operated at a working surface is provided. The projector includes a casing, a light source module and a transparent blocking member. The casing has a first surface and a second surface. The first surface is adjacent to the working surface and opposite to the second surface. The second surface has an opening. The light source module corresponding to the opening is disposed in the casing. The light source module can be assembled and disassembled through the opening. The transparent blocking member is disposed on the second surface and covers the opening.
