Walkable Clean Room Ceiling Beam and Light Fixture
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current walkable ceiling systems in clean rooms face structural weaknesses due to the installation of traditional fluorescent fixtures, which create tripping hazards and require robust, costly construction to support the weight and maintain structural integrity, while also being inflexible for changes in lighting plans.
Innovation Solution
A structural beam and light fixture system that integrates a flush design with extruded aluminum components, allowing for a seamless ceiling surface and load transfer between panels, eliminating the need for factory-cut holes and enhancing structural strength and flexibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional fluorescent fixtures are installed by penetrating ceiling panels, then lighting function is achieved, but structural strength of the ceiling is reduced and tripping hazards are created
Solution Approach 1:
The lighting system is segmented into separate functional components: the ceiling panels maintain their structural integrity while the lighting fixtures are installed in discrete locations without penetrating the panels. The fixtures are positioned to provide illumination while maintaining the continuous structural surface of the ceiling.
Solution Approach 2:
An intermediary mounting structure is introduced that allows lighting fixtures to be installed without directly penetrating the ceiling panels. This intermediary system enables the fixtures to be positioned for optimal lighting while preserving the structural continuity and strength of the ceiling panels.
2Weight of stationary object
If ceiling panels are made thinner for reduced weight and cost, then material cost and weight are reduced, but structural robustness is compromised
Solution Approach 1:
The ceiling system utilizes composite construction with steel panels bonded to an aluminum honeycomb core, creating a lightweight yet structurally robust panel. This composite material approach allows the ceiling to achieve both reduced weight and maintained structural strength, resolving the contradiction between thinning panels for cost/weight reduction and maintaining structural robustness.
3Ease of operation
If holes are cut in ceiling panels to support fluorescent fixtures, then lighting installation is enabled, but manufacturing complexity and cost increase
Solution Approach 1:
The ceiling system is segmented into modular panels that are manufactured without openings, maintaining simple factory production. Lighting fixtures are installed as separate modular units that interface with the completed panels, enabling flexible lighting installation without complicating panel manufacturing.
Solution Approach 2:
The ceiling panels are pre-manufactured in their complete form without openings or cutouts at the factory, simplifying manufacturing. The lighting installation is performed as a subsequent step using pre-designed mounting interfaces, separating the manufacturing and installation processes to optimize both.

AI summary
A structural beam and light fixture for a walkable ceiling of a clean room is composed of an elongated channel and a lamp disposed in the elongated channel. The lamp is configured to direct light through the bottom side of the elongated channel. The structural beam and light fixture is attached to adjoining ceiling components and is configured to support a load applied to the adjoining ceiling components. The structural beam and light fixture, combined with other walkable ceiling components, define ceiling top and bottom sides that are flush.
