Movable Light Sockets with Joystick Platform
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Recessed wall light fixtures with multiple lamps are typically not adjustable, limiting their ability to direct light in various primary directions, especially when mounted on angled ceilings or walls.
Innovation Solution
A light fixture design featuring a cover with movable light sockets, a joystick, and a movable platform that allows each light socket to adjust its primary direction in multiple dimensions without altering the fixture's position, using a combination of spherical and sliding movements facilitated by shafts and ball-and-socket joints.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If recessed wall light fixtures are designed with multiple lamps in a fixed configuration, then the fixture structure is simple and stable, but the light direction cannot be adjusted to adapt to different mounting angles and lighting needs
Solution Approach 1:
The fixture is divided into independent modular components: a stationary cover and multiple movable light sockets, each capable of independent adjustment. This segmentation allows each socket to be adjusted individually without affecting others, providing versatile light direction control while keeping the overall structure manageable through modular design
Solution Approach 2:
The light sockets are designed with movable joints (ball-and-socket connections) that enable dynamic adjustment of light direction. The sockets can rotate and tilt independently within their openings, transforming the fixed configuration into a dynamic system that adapts to various mounting angles and lighting requirements
2Ease of operation
If standing lamps and desk lamps include adjustment mechanisms for primary beam direction, then light direction is adjustable, but recessed wall fixtures lack such mechanisms and remain fixed
Solution Approach 1:
Ball-and-socket joints are employed at critical connection points, enabling spherical movement of the light sockets. This spherical mechanism allows adjustment in multiple directions (up/down, left/right, tilting) through simple rotational motions, providing ease of operation similar to portable lamps while maintaining a compact recessed fixture structure
Solution Approach 2:
The movable platform acts as an intermediary mechanism that translates small adjustments at the joystick control into larger movements of the light sockets. This mechanical advantage system makes it easier to adjust light direction with minimal effort while maintaining precise control
3Adaptability or versatility
If the primary beam direction is fixed perpendicular to the mounting wall, then the fixture structure is simple and stable, but it cannot adapt to angled ceilings or walls
Solution Approach 1:
The fixture separates the stationary mounting component (cover) from the adjustable lighting components (sockets). This segmentation allows the cover to remain firmly mounted on angled surfaces while the sockets can be independently oriented to achieve the desired light direction, adapting to various mounting angles without compromising structural stability
Solution Approach 2:
The invention combines the stability of a fixed recessed mounting structure with the adjustability of movable light sockets. The cover provides stable mounting on angled surfaces, while the movable sockets combine with this stable base to create a system that maintains structural integrity while achieving adaptability to different lighting requirements

AI summary
A light fixture has a cover, a joystick, a plurality of light sockets, a movable platform, and a plurality of shafts. The cover has a plurality of openings receiving the plurality of light sockets, each light socket spherically movable within its opening. The joystick is from a first side of the cover, and has a distal end. The movable platform engages the distal end of joystick to move in at least two dimensions responsive to movement of the joystick. Each of the plurality of shafts has a first end spherically engaging the movable platform and a second end rigidly coupled to a corresponding light socket. Spherical movement of the joystick causes movement of the movable platform, and movement of the platform causes movement of the second end of the shafts. Movement of the second end of the shafts causes spherical movement of the light sockets.
