Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing boundary-mounted lighting systems lack versatile control over light direction and easy access for servicing, such as adjustments and component replacements, due to limited directional control and complex internal component access.
Innovation Solution
The lighting system incorporates a pan assembly with a pinion gear and central fixed gear for rotational control, a tilt assembly with a tilt adjustment screw and leadscrew for vertical adjustment, and a universal joint assembly for combined tilt and pan movements, along with a support assembly for adjustable mounting, enhancing directional control and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a boundary-mounted lighting system is designed with fixed mounting, then installation is simple, but directional control of light emission is limited
Solution Approach 1:
The patent applies dynamics by transforming the fixed mounting structure into a dynamic adjustable system. The pan assembly with pinion gear and sector gear enables rotational movement, while the tilt assembly with leadscrew and adjustment screw provides vertical angle adjustment. This allows the lighting system to dynamically change light direction while maintaining secure boundary mounting.
2Ease of repair
If the lighting system has a sealed enclosure, then protection is improved, but access for servicing and component replacement becomes difficult
Solution Approach 1:
The patent applies segmentation by dividing the enclosure into modular sections. The pan assembly and tilt assembly are separable components that can be independently accessed. The adjustment mechanisms are designed with accessible interfaces that allow servicing without completely disassembling the enclosure, maintaining protection while enabling maintenance.
3Adaptability or versatility
If the lighting system uses fixed position mounting, then installation is straightforward, but adaptability to different mounting locations is reduced
Solution Approach 1:
The patent applies universality by designing a multi-functional adjustment mechanism that handles both pan (horizontal) and tilt (vertical) movements. The combined pan and tilt assemblies provide universal adaptability to various boundary mounting locations and orientations, while the modular design prevents excessive complexity through standardized components.
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 system provides improved directional control and ease of maintenance by allowing for extensive rotational and vertical adjustments, as well as secure mounting options, thereby optimizing light emission and facilitating servicing.
Implementation Method 1
a pan assembly having a pan ring, a pinion gear, and a central fixed gear. Further in this example of the lighting system, rotating the pinion gear may cause the pan ring to be rotated around a pan axis through a range of rotation around the central fixed gear
Implementation Method 2
a tilt assembly including a tilt adjustment screw, a leadscrew, and two spaced-apart panels each having an arcuate slot, the arcuate slots being mutually concentric and collectively defining an arcuate tilt path, the heat-sink being movably attached to the arcuate slots. Additionally in this example of the lighting system, the tilt adjustment screw may be configured for driving the leadscrew to cause movement of the heat-sink to a selected position along the tilt path
Implementation Method 3
a heat-sink being attached to the visible-light source
Implementation Method 4
a universal joint assembly. Further in this example of the lighting system, the universal joint assembly may include a gimbal and a swing bar having swing arms
