Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Light fixture assemblies face issues with glare due to smaller apertures, difficulty in horizontal movement of heat sinks, and the need for continuous ceiling surfaces without trim, while maintaining access for component replacement.
Innovation Solution
A light fixture assembly design featuring a carriage with a spring mechanism allowing horizontal and vertical movement of the heat sink, coupled with a baffle and glare mask to reduce glare, and a flexible baffle for easy access and installation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Shape
If the aperture size is reduced to achieve a continuous ceiling appearance, then the aesthetic quality is improved, but the access to internal components becomes more difficult
Solution Approach 1:
The baffle is designed to be movable rather than fixed, allowing it to be easily removed and repositioned. The spring mechanism enables the baffle to move horizontally and vertically, providing access to internal components while maintaining the continuous ceiling appearance when in position.
Solution Approach 2:
The baffle is separated from the heat sink and mounted independently on the carriage, allowing it to be moved and removed separately. This segmentation enables easy access to the heat sink and other internal components without damaging the ceiling finish.
2Stability of the object's composition
If multiple springs are used to hold components in place, then the stability is improved, but the horizontal movement capability is reduced
Solution Approach 1:
The spring mechanism is segmented into multiple independent spring bands (first spring band and second spring band) that can move and compress independently. This allows the heat sink to be held stably in the vertical direction while maintaining horizontal movement capability through the coordinated action of the segmented spring structure.
Solution Approach 2:
Different portions of the spring mechanism have different functional properties - the spring bands provide vertical retention force while the carriage structure enables horizontal movement. The localized compression of spring bands allows selective constraint in the vertical direction while preserving horizontal mobility.
3Stability of the object's composition
If the heat sink is constrained to prevent angled movement, then the stability is improved, but the ease of maintenance is worsened
Solution Approach 1:
The heat sink is mounted on a carriage with a spring mechanism that allows dynamic movement in horizontal and vertical directions. The spring bands can be compressed to hold the heat sink in position during operation, but the entire carriage can be moved to access the heat sink for maintenance, combining stability with ease of maintenance.
Solution Approach 2:
The carriage acts as an intermediary between the fixed mounting structure and the heat sink. It provides a movable platform that can be positioned to access the heat sink while the spring mechanism maintains stable positioning during normal operation, separating the functions of constraint and accessibility.
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 enables reduced glare, facilitates easy access for component replacement, and maintains a continuous ceiling appearance by allowing horizontal and vertical movement of the heat sink, while minimizing glare and providing access for maintenance.
Implementation Method 1
A spring is fixedly coupled to the second side wall extending between the second side wall and the light assembly. The spring is partially compressed by the light assembly while allowing horizontal and vertical movement of at least a portion of the light assembly.
