Trompe-l'oeil Skylight Elevator Frame Shadow Elimination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for creating a trompe-l'oeil skylight fail to convincingly replicate a real skylight, especially in non-rectangular shapes, and often produce unwanted shadows due to the T-bar ceiling grid, making them impractical for interior spaces without roof exposure.
Innovation Solution
A system utilizing an elevator frame that raises a translucent panel above the T-bar grid, eliminating shadows and creating an illusion of a casement window frame, allowing for non-rectangular shapes and unified recessed mounting with a rectangular flush plate, thus eliminating the internal grid system.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a translucent panel is deployed as a diffuser panel in a hung ceiling grid, then the system is easy to install and maintain, but unwanted shadows are created by the T-bar grid
Solution Approach 1:
The translucent panel is elevated from the plane of the T-bar grid to a higher dimension, creating a shadow-free zone between the panel and the grid structure. This dimensional separation eliminates the shadow problem while preserving the ease of installation through the elevator frame mechanism.
Solution Approach 2:
An elevator frame structure serves as an intermediary element between the T-bar grid and the translucent panel. This intermediary supports the panel above the grid, blocking the grid from casting shadows on the panel while maintaining structural support and ease of installation.
2Adaptability or versatility
If a trompe-l'oeil skylight is created using a translucent panel in a hung ceiling, then the environment becomes more pleasant, but the illusion of a real skylight is not achieved
Solution Approach 1:
The translucent panel displays an image of the sky that replicates the appearance of a real skylight view. By combining this visual copy with the elevator frame that mimics a casement window frame structure, the system creates a convincing trompe-l'oeil effect that enhances the environment while maintaining realism.
Solution Approach 2:
The translucent panel utilizes color and optical properties to replicate the appearance of the sky and clouds. By manipulating the visual characteristics of the panel to match natural sky conditions, the system creates a realistic illusion that enhances the environmental atmosphere.
3Adaptability or versatility
If a non-rectangular trompe-l'oeil skylight is created, then design flexibility is improved, but manufacturing and installation difficulty increases
Solution Approach 1:
The non-rectangular translucent panel is divided into manageable segments that can be manufactured using standard rectangular panels and then assembled or trimmed to create the desired shape. The elevator frame is also segmented to accommodate the non-rectangular configuration, simplifying manufacturing while maintaining design flexibility.
Solution Approach 2:
The elevator frame structure serves multiple functions: it supports the translucent panel, creates the shadow-free zone, provides the casement window frame illusion, and accommodates various panel shapes. This multi-functionality reduces overall system complexity while enabling design flexibility for non-rectangular configurations.
