Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
There is a need for thin lighting fixtures that can be hidden in ceilings, providing a discreet source of light without the visible body of the light source.
Innovation Solution
A light fixture design featuring a body with a cavity and an opening at the bottom, equipped with tracks for bar hangers, a source of light, a reflector, and a plate with a central opening to allow light passage, all constructed from materials like aluminum and steel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Length of moving object
If the light fixture body is made thin to be hidden in ceiling, then the visibility of the light source is reduced, but the structural strength and heat dissipation capability deteriorate
Solution Approach 1:
The light fixture body uses aluminum material that combines adequate structural strength with thin profile capability, allowing the fixture to maintain both mechanical integrity and a slim form factor suitable for ceiling recess installation
2Length of moving object
If the light fixture body is made thin to be hidden in ceiling, then the visibility of the light source is reduced, but the heat dissipation capability deteriorates
Solution Approach 1:
The reflector uses a curved parabolic surface that efficiently directs and distributes light while also serving as a heat reflection surface, helping to manage thermal energy within the constrained thin fixture volume
Solution Approach 2:
The aluminum body material provides inherent thermal conductivity properties that enable effective heat dissipation even in a thin profile, complemented by the reflective surfaces that manage thermal radiation
3Length of moving object
If a plate is added to close the cavity opening for discreet installation, then the hiding effect is improved, but the light passage capability is restricted
Solution Approach 1:
The plate is segmented with a central opening that separates the light passage function from the structural closing function, allowing the plate to provide both discreet installation appearance and adequate light transmission capability
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The design allows for a thin, discreet lighting solution that can be easily attached to ceilings, providing effective light distribution while maintaining a slim profile.
Implementation Method 1
a reflector inside of the cavity below the source of light
Implementation Method 2
The trim can be attached to the plate with magnets. The trim can comprise a plurality of magnets with exposed surfaces for attachment to the plate
