Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional recessed lighting systems lack the ability to provide additional lighting effects beyond standard downward illumination, limiting their versatility for special occasions like entertaining.
Innovation Solution
A light unit with a movable light module that can switch between a retracted position for standard downward lighting and an extended position for radial lighting, featuring a cylindrical design with separate lighting devices for downward and radial emission, and a motor-driven mechanism for position adjustment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a standard recessed light is used, then the lighting structure is simple and reliable, but the lighting functionality is limited to downward illumination only
Solution Approach 1:
The light module is made movable between retracted and extended positions. When retracted, it provides standard downward lighting. When extended, it exposes the side light emitting surface for radial lighting effects. This dynamic positioning allows a single device to perform multiple lighting functions.
Solution Approach 2:
The light module integrates two different light emitting surfaces (downward and radial) into a single component. By moving the light module between retracted and extended positions, the system can switch between standard downlighting and special effect radial lighting, making one device serve multiple purposes.
2Adaptability or versatility
If additional lighting fixtures are installed to provide radial lighting effects, then the lighting versatility is improved, but the device complexity and installation requirements increase
Solution Approach 1:
The patent combines two different lighting functions (downward illumination and radial lighting effects) into a single light module. The light module includes both a downward light emitting surface and a radial light emitting surface, eliminating the need for separate fixtures and reducing overall system complexity.
Solution Approach 2:
A single light module performs the functions of multiple fixtures by integrating different light emitting surfaces. The downward surface provides standard illumination while the radial surface provides special effects lighting, allowing one device to replace what would traditionally require multiple fixtures.
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
Enables the light unit to function as both a standard downlight and a feature-rich lighting system capable of providing radial lighting effects, enhancing versatility and ambiance without the need for additional fixtures.
Implementation Method 1
the light module includes a third cylindrical member secured around the outer surface thereof, the third cylindrical member including a plurality of helical grooves therein to receive lugs provided on the outer surface of the second cylindrical member such that rotation of the second cylindrical member causes translational movement of the third cylindrical member
