Adjustable Light Fixture Sloped Ceiling Rotation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional recessed lighting fixtures are typically designed for specific ceiling slopes, making them inflexible for installation on sloped ceilings, where achieving perpendicular lamp orientation is challenging.
Innovation Solution
An adjustable light fixture design featuring a frame and lamp assembly that can be rotatably connected about two axes, allowing for directional adjustment to accommodate varying ceiling slopes, with a mounting hanger system for secure attachment and a pivot mechanism for precise angle control.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional recessed lighting fixtures are designed for specific ceiling slopes, then the lamp orientation can be maintained perpendicular to the floor, but the fixture lacks flexibility for installation on varying ceiling slopes
Solution Approach 1:
The patent applies dynamics by making the lamp assembly rotatable relative to the frame about a second axis that is offset from the first axis. This rotational capability allows the lamp orientation to be dynamically adjusted to remain perpendicular to the floor regardless of the ceiling slope, thereby resolving the contradiction between adaptability to varying ceiling slopes and maintaining simple fixture structure.
Solution Approach 2:
The patent segments the fixture into two main components: a frame that connects to the support and a lamp assembly that can rotate relative to the frame. This segmentation allows independent adjustment of the lamp assembly orientation while keeping the frame structure simple, thus enabling adaptability to different ceiling slopes without significantly increasing overall device complexity.
2Adaptability or versatility
If the lamp assembly is made adjustable with dual-axis rotation, then flexibility for different ceiling slopes is improved, but the device complexity increases
Solution Approach 1:
The lamp assembly is made rotatable relative to the frame about a second axis offset from the first axis, creating a dynamic adjustment mechanism. This allows the lamp orientation to be independently adjusted from the frame orientation, providing flexibility for different ceiling slopes while maintaining a relatively simple mechanism through the use of offset rotational axes rather than complex multi-stage adjustments.
