Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing light fixtures lack precise and efficient mechanisms for independent adjustment of a light source relative to a reflector, limiting the ability to optimize light placement and focal point definition.
Innovation Solution
A three-directional adjustment system comprising a first inner ring, a second middle ring, and a third outer ring, where each ring is movable independently in orthogonal directions, allowing precise tilting and linear translation of the light source within the reflector, facilitated by screwing mechanisms and a rotating outer ring that interacts with a toothed wheel and frame components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If a single adjustment mechanism is used for the light source, then the device complexity is reduced, but the adjustment precision and independence in different directions deteriorates
Solution Approach 1:
The adjustment mechanism is segmented into three independent rings (first inner ring, second middle ring, third outer ring), each responsible for adjusting the light source in a specific direction. This segmentation allows precise independent control of adjustment in each direction without interfering with other directions, resolving the contradiction between adjustment precision and device complexity.
2Ease of operation
If the light source adjustment is coupled in multiple directions, then the device structure is simplified, but the ability to independently adjust each direction deteriorates
Solution Approach 1:
The adjustment system is divided into three independently operable rings, where the first inner ring adjusts one direction, the second middle ring adjusts a second direction, and the third outer ring adjusts a third direction. Each ring can be operated independently to adjust the light source position without affecting adjustments in other directions, achieving ease of operation with independent adjustment capability.
Solution Approach 2:
The three rings are nested within each other (first inner ring within second middle ring, which is within third outer ring), creating a compact structure where each nested ring provides independent adjustment functionality. This nesting arrangement achieves independent adjustment capability while maintaining a relatively compact device structure.
3Manufacturing precision
If the light source placement is not precisely adjustable, then the device structure remains simple, but the focal point definition and light optimization capability deteriorates
Solution Approach 1:
The adjustment mechanism is divided into three independently controllable rings, each capable of precise adjustment in its specific direction. This segmentation enables high-precision positioning of the light source in three-dimensional space, achieving manufacturing precision for light source placement while managing device complexity through modular independent adjustment units.
Solution Approach 2:
The patent implements three-dimensional adjustment capability by adding adjustment in multiple directions (first direction, second orthogonal direction, third orthogonal direction). This multi-dimensional adjustment approach enables precise positioning of the light source in space, achieving high manufacturing precision for light source placement relative to the reflector.

AI summary
A light fixture comprising a lamp assembly including a socket and a light source extending along a light fixture axial direction from one side of the socket. The light source is placed in a reflector such that light emitted by the light source is reflected by the reflector in the axial direction. The socket is supported by an inner ring which is supported by a middle ring and the middle ring is supporting by an outer ring. The inner ring is tiltable about a first axis that is orthogonal to the axial direction for tilting the light source, the middle ring is tiltable about a second axis that is orthogonal to both the axial direction and the first axis for tilting the inner ring, and the middle ring being movable with respect to the outer ring in the axial direction.
