Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing lamps are difficult to adjust as they require loosening or tightening screws to change the light exit angle, which is cumbersome and often requires additional tools.
Innovation Solution
An angle-adjustable lamp design where the lamp body is rotatably mounted in an accommodating cavity with a damping fit, allowing for easy adjustment of the light exit angle without the need for screws or tools.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the lamp body is rotatably mounted with a damping fit in the accommodating cavity, then the ease of operation is improved, but the device complexity increases
Solution Approach 1:
The patent replaces the traditional screw-based mechanical fastening system with a damping fit mechanism. The damping member (such as a rubber ring or elastic element) provides friction-based holding force without requiring threads, nuts, or other complex mechanical fasteners. This substitution eliminates the need for screw loosening/tightening operations while maintaining the ability to hold the lamp body at adjusted positions, thereby improving ease of operation without proportionally increasing device complexity.
Solution Approach 2:
The patent utilizes changes in friction parameters through the damping member to achieve the desired functionality. By selecting materials with appropriate friction coefficients and designing the damping member with specific elasticity and contact surface areas, the system achieves sufficient holding force to maintain the lamp body at various angles without requiring additional mechanical fastening components. This parameter-based approach simplifies the overall structure while enabling easy adjustment.
2Adaptability or versatility
If the axis of the rotating shaft is not perpendicular to the light exit surface, then the adaptability is improved, but the manufacturing precision requirements increase
Solution Approach 1:
The patent employs a rotatable lamp body mounted on a rotating shaft that allows dynamic adjustment of the light exit angle. The non-perpendicular arrangement of the rotating shaft relative to the light exit surface enables the lamp to achieve a broader range of illumination angles by rotating around the shaft axis. This dynamic configuration provides greater adaptability compared to a fixed perpendicular arrangement, allowing the lamp to cover more directional requirements without needing multiple fixed-position lamps.

Function Achieved in This Case
The lamp body can be adjusted to any desired position and stay there due to the damping fit, providing a convenient and smooth adjustment mechanism for the light exit angle.

AI summary
An angle-adjustable lamp is provided, including a base shell and a lamp body. The base shell is provided with an accommodating cavity. The lamp body is rotatably mounted in the accommodating cavity and is in a damping fit with the accommodating cavity. The lamp body includes a lamp body main body and a rotating shaft having one end connected with the lamp body main body. The lamp body main body has a light exit surface for emitting light. An axis of the rotating shaft is not perpendicular to the light exit surface. An end of the rotating shaft away from the lamp body main body runs through the base shell and extends to an outside of the base shell. According to the present disclosure, the lamp body is rotatably mounted in the accommodating cavity, so that a light exit angle of the lamp body is adjustable.
