Rotating Multi-Socket Light Fixture for Ladder-Free Bulb Replacement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing recessed light fixtures require difficult ladder access for bulb changes due to their installation within ceiling hollows, necessitating a solution for easy and efficient bulb replacement.
Innovation Solution
A rotating multi-socket light fixture with a wheel-mounted bulb sockets system, driven by a rotational motor and vertical drive system, allowing for remote operation and easy bulb access through a ceiling panel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a recessed light fixture is installed within a ceiling hollow, then the light provides concentrated illumination in a downward direction, but changing the light bulb becomes extremely difficult requiring ladder access
Solution Approach 1:
The light fixture is divided into multiple segments: a rotating wheel with multiple light bulb sockets arranged circumferentially, allowing the bulb to be accessed from different positions around the ceiling opening rather than requiring direct access from below
Solution Approach 2:
The wheel is made rotatable by a drive motor, enabling dynamic repositioning of the light bulb sockets. This allows the system to bring a bulb to an accessible position at the ceiling level for easy replacement without requiring ladder access
2Stability of the object's composition
If the light bulb is mounted within the ceiling panel, then the light fixture provides stable installation, but accessing the bulb requires climbing a ladder which creates safety risks
Solution Approach 1:
The rotating wheel acts as an intermediary mechanism between the ceiling-mounted fixture and the user. It provides a safe, automated method to bring the bulb to an accessible position without requiring the user to climb a ladder, thus eliminating safety hazards while maintaining stable installation
3Ease of manufacture
If a single light bulb socket is used in a recessed fixture, then the installation is simple, but the fixture cannot provide multiple lighting options or efficient bulb replacement
Solution Approach 1:
The wheel incorporates multiple light bulb sockets in addition to the primary ceiling-mounted socket, providing multiple lighting options and functions within a single fixture. The system can illuminate from different positions around the ceiling opening, enhancing versatility while maintaining relatively simple installation through modular design

AI summary
The rotating multi-socket light fixture may be used in combination with a ceiling panel or the like, allowing for changing of light bulbs for a recessed light, for example. The rotating multi-socket light fixture includes a plurality of light bulb sockets mounted circumferentially on a wheel for respectively removably receiving a plurality of light bulbs. The wheel is mounted on, and rotationally driven by, a rotational drive motor. The rotational drive motor is mounted on a vertical support such that the rotational drive motor may be vertically adjusted with respect to the vertical support. A vertical drive motor may be mounted on an upper end of the vertical support for selectively driving vertical translation of the rotational drive motor with respect to the vertical support. A lower end of the vertical support is mounted on an upper surface of the ceiling panel, such that the vertical support extends upwardly therefrom.
