Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamps lack the ability to adjust the light exit angle in multiple dimensions, limiting their effectiveness in illuminating various positions.
Innovation Solution
An angle-adjustable lamp design that allows the lamp body to rotate relative to a guide rail frame and the guide rail frame to rotate relative to a frame body, with non-parallel axes of rotation, enabling full directional adjustment of the light exit angle.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If existing lamps are designed with fixed or single-dimension rotation only, then the structure is simple, but the light exit angle cannot be adjusted to any direction
Solution Approach 1:
The lamp structure is divided into three main segments: frame body, guide rail frame, and lamp body. Each segment can rotate independently relative to the previous one, enabling multi-directional adjustment. The guide rail frame rotates relative to the frame body along a first axis, while the lamp body rotates relative to the guide rail frame along a second axis that is not parallel to the first axis, creating comprehensive angular coverage.
Solution Approach 2:
The patent transitions from single-dimension rotation to two-dimension rotation by introducing a second rotation axis that is not parallel to the first rotation axis. The guide rail frame provides rotation along the first axis, and the lamp body provides rotation along the second axis, together forming a two-dimensional adjustment space that enables the light exit angle to be adjusted to any direction.
2Adaptability or versatility
If the axis of rotation of the guide rail frame is made parallel to the axis of rotation of the lamp body, then the structure is simpler, but the light exit angle cannot be adjusted to any direction
Solution Approach 1:
The patent deliberately uses asymmetric arrangement of rotation axes. The first rotation axis (guide rail frame to frame body) and the second rotation axis (lamp body to guide rail frame) are designed to be non-parallel, creating an asymmetric configuration that enables full directional coverage. This asymmetric design is particularly embodied in the perpendicular arrangement where the axes intersect at right angles, maximizing the adjustment range.
Solution Approach 2:
The guide rail frame serves as an intermediary component between the frame body and the lamp body. It provides the first rotation axis relative to the frame body and supports the second rotation axis for the lamp body. This intermediary structure with non-parallel rotation axes acts as a mediator that transforms the simple single-axis rotation into complex multi-directional adjustment capability.

AI summary
An angle-adjustable lamp is provided, including a frame body, a guide rail frame and a lamp body. The frame body has a mounting space, and a bottom surface of the mounting space runs through the frame body and forms a first opening in the frame body. The guide rail frame is rotatably arranged in the mounting space, the lamp body is rotatably arranged on the guide rail frame, and an axis of rotation of the guide rail frame with respect to the mounting space is not parallel with an axis of rotation of the lamp body with respect to the guide rail frame. According to the present disclosure, by rotating the lamp body with respect to the guide rail frame, a light exit angle of the lamp body can be adjusted.
