Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current light sources with adjustable output directionality and shape often compromise on visual aesthetics and create visual clutter, as they require significant structural changes to alter the light beam direction, which is not addressed by existing solutions.
Innovation Solution
A luminaire with pivotally coupled light modules that adjust directionality without altering the spatial profile, using a housing with a coupling structure that allows light modules to pivot about a transversal axis perpendicular to the longitudinal axis, maintaining the luminaire's overall appearance and reducing visual clutter.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If light sources are made adjustable in directionality and shape, then lighting versatility is improved, but visual aesthetics and spatial profile consistency deteriorate
Solution Approach 1:
The luminaire is divided into multiple independent light modules that can be adjusted separately. Each light module contains a light source and optics assembly that can pivot independently relative to the housing, allowing directional adjustment without altering the overall spatial profile of the luminaire. This segmentation enables versatility in light output while maintaining consistent external appearance.
Solution Approach 2:
A coupling structure serves as an intermediary mechanism between the light modules and the housing. This coupling structure allows the light modules to pivot and adjust their orientation while remaining constrained within the housing boundaries. The intermediary mechanism transmits adjustment motions while preserving the overall spatial profile, resolving the contradiction between adjustability and shape consistency.
2Ease of operation
If light modules are made movable to adjust directionality, then lighting control is improved, but visual clutter increases
Solution Approach 1:
The light modules are nested within the housing structure, with adjustment mechanisms integrated into the housing itself. The light modules can pivot within the housing boundaries, and the housing may include transparent or translucent portions that allow the nested structure to be visually appreciated rather than concealed. This nesting approach provides lighting control while minimizing visual clutter by integrating movement within the overall form.
Solution Approach 2:
The adjustment mechanism operates in a dimensional space that does not compromise the external appearance. Light modules pivot about axes that allow directional change while maintaining the luminaire's overall spatial profile. The coupling structure enables movement in multiple dimensions while constraining the external dimensions to preserve aesthetic appearance, effectively separating functional adjustment from visual impact.
3Adaptability or versatility
If the luminaire structure is made complex to enable adjustment, then lighting versatility is improved, but device complexity increases
Solution Approach 1:
The coupling structure serves multiple functions simultaneously: it provides the pivot mechanism for light module adjustment, maintains the spatial profile of the luminaire, and integrates the adjustment capability into the housing itself. This multi-functionality reduces the need for separate adjustment mechanisms, thereby reducing overall device complexity while maintaining lighting versatility.
Solution Approach 2:
The luminaire incorporates dynamic elements in the form of pivotable light modules that can be adjusted during operation. The coupling structure enables these dynamic adjustments while maintaining a relatively simple overall structure. The dynamic capability is achieved through straightforward pivot mechanisms rather than complex actuation systems, balancing versatility with structural simplicity.
