Removable Debris Shield for Light Fixtures During Construction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light fixture devices are unable to illuminate construction sites during building construction due to airborne debris contamination, requiring temporary lighting installations to prevent damage to the lighting components.
Innovation Solution
A removable transparent or translucent debris shield with retaining projections is designed to attach to the light fixture device, allowing it to be used during construction while preventing debris entry and easily removable after the construction process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a removable cardboard cover is provided in the light source aperture to prevent construction debris from entering the light fixture device, then the lighting components are protected from contamination, but the light fixture device cannot be used to illuminate the building area during construction
Solution Approach 1:
A transparent or translucent debris shield is introduced as an intermediary component between the light source aperture and the construction environment. This shield serves dual functions: it blocks construction debris from entering the light fixture device while simultaneously allowing light to pass through, enabling the fixture to illuminate the building area during construction. The shield is removably attached to the trim ring, facilitating easy installation and removal.
2Productivity
If a debris shield is installed to allow the light fixture device to be used during construction, then illumination capability is maintained, but the device structure becomes more complex
Solution Approach 1:
The debris shield is designed to perform multiple functions simultaneously: it acts as a physical barrier against construction debris, serves as a light-transmitting window for illumination, and provides a removable attachment mechanism to the trim ring. By integrating these multiple functions into a single component, the overall device complexity is minimized while achieving continuous illumination capability during construction.
Solution Approach 2:
The debris shield is constructed as a thin, transparent or translucent barrier that can be easily attached and removed from the trim ring. This flexible, thin-film approach minimizes the added structural complexity while effectively preventing debris entry and maintaining light transmission for illumination purposes.
3Ease of operation
If a removable debris shield with retaining projections is used, then the shield can be easily attached and removed, but the retaining mechanism adds manufacturing complexity
Solution Approach 1:
The retention mechanism is segmented into discrete retaining projections that are distributed around the perimeter of the debris shield. These projections can be independently formed and engaged with corresponding features on the trim ring, allowing for simplified manufacturing processes such as injection molding or stamping. The segmented design enables easy attachment and removal while maintaining manufacturability.

AI summary
A debris shield for preventing debris from entering a light fixture device during a construction process while allowing the light fixture device to be used to illuminate an area where the construction process is taking place includes a transparent or translucent body and at least one projection arranged on or associated with the body for removably retaining the debris shield to the light fixture device. The debris shield can be removed from the trim ring after the construction process is completed by puncturing a closure covering an opening in the body of the debris shield and grasping the opening to pull the debris shield from the trim ring. Alternatively, the debris shield can be removed from the trim ring after the construction process is completed by grasping a pull tab on the body of the debris shield and using the pull tab to pull the debris shield from the trim ring.
