Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing suspended tile light ceiling assemblies with T-bar grids are limited by standardized dimensions, restricting the versatility and flexibility of lighting patterns and luminaire types, as they require specific dimensions for tile light luminaires and mineral fiber ceiling tiles, limiting adaptability across different grid dimensions.

Innovation Solution

A tile light luminaire with a housing periphery smaller than the T-bar grid cell, featuring complementary periphery sections for abutment with both the grid and ceiling tiles, allowing interchangeability across different grid dimensions and enabling complex lighting patterns through straight and curved designs, with support rails and mounting pins for secure installation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If tile light luminaires are designed with standardized dimensions matching T-bar grid cells, then they can be properly installed in the grid, but they limit versatility and flexibility for different grid dimensions and lighting patterns

Engineering Contradiction:

Improveadaptability to different grid dimensionsVSAvoidluminaire housing structure

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The luminaire housing is designed with a universal periphery structure that can adapt to different T-bar grid dimensions (600x600mm, 625x625mm, 675x675mm, and rectangular grids). The housing includes a first periphery section for abutment with the T-bar grid and a second periphery section for abutment with ceiling tiles, allowing the same luminaire design to be used across multiple grid standards without requiring dimension-specific variants.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The luminaire housing periphery is segmented into distinct functional sections: a first periphery section configured for abutment with the T-bar grid cell and a second periphery section configured for abutment with the ceiling tile. This segmentation allows each section to be optimized for its specific interaction while maintaining overall adaptability to different grid dimensions and configurations.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If the luminaire housing periphery matches the T-bar grid cell inner periphery exactly, then it provides stable support, but it prevents interchangeability across different grid dimensions

Engineering Contradiction:

Improveinterchangeability across grid dimensionsVSAvoidmounting stability

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

Inventive Principle:

Principle #6Universality (Multi-functionality)

3Area of stationary object

If the luminaire occupies the full T-bar grid cell area, then it maximizes lighting coverage, but it limits the use of complementary ceiling tiles for acoustic and aesthetic functions

Engineering Contradiction:

Improvelighting coverage areaVSAvoidlighting pattern flexibility

Core Design Contradiction:

Area of stationary objectVSAdaptability or versatility

Solution Approach 1:

The luminaire housing periphery is segmented into distinct functional sections: a first periphery section configured for abutment with the T-bar grid cell and a second periphery section configured for abutment with the ceiling tile. This segmentation allows the luminaire to occupy part of the grid cell while leaving space for complementary ceiling tiles, enabling flexible lighting patterns and acoustic tile integration.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The luminaire housing is designed with different periphery sections having different functions: the first periphery section interacts with the T-bar grid for structural support, while the second periphery section interacts with the ceiling tile for acoustic and aesthetic purposes. This local differentiation allows the system to optimize both lighting coverage and acoustic tile functionality simultaneously.

Inventive Principle:

Principle #3Local quality

AI summary

According to a first example of the disclosure, a tile light luminaire (120) is proposed, which suitable for laying in the T-bar grid (11) of a suspended ceiling assembly (10), the tile light luminaire (120) having a luminaire housing (220) with an outer housing periphery (120z) being smaller than the inner periphery (10z) of a T-bar grid cell, and wherein a first periphery section (120z1) of the housing periphery (120z) of the tile light luminaire is structured for abutment with a section part of the periphery of the T-bar grid cell, and a second periphery section (120z2) of the housing periphery (120z) of the tile light luminaire is structured for abutment with a section part (130z2) of the periphery of a ceiling tile (130). As the tile light luminaire (120) has an outer periphery dimension (120z), which is smaller than the inner periphery dimension (10z) of a T-bar grid cell of a suspended ceiling assembly (10), such tile light luminaire is suitable to be interchanged between T-bar grids having different dimensions, either square or rectangular.
