Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional lamps are inflexible in adjusting light field and illuminance, requiring multiple fittings and increased costs when different lighting effects are needed, as the light source is fixed and cannot be easily adjusted.
Innovation Solution
A lamp design featuring radially disposed light-emitting members that rotate about a non-parallel axis, connected to a transmission mechanism allowing for adjustable light-emitting angles, with a motor and control device for remote operation, enabling users to change lighting effects without additional fittings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the light source is securely mounted in the lamp holder, then the lamp structure is simple and stable, but the light-emitting angle cannot be adjusted
Solution Approach 1:
The light-emitting assembly is designed to be rotatable relative to the lamp holder, transforming the static mounting into a dynamic adjustable structure. The transmission mechanism enables the light-emitting assembly to rotate around a rotation axis, allowing continuous adjustment of the light-emitting angle while maintaining structural integrity through the defined rotational degrees of freedom.
Solution Approach 2:
The lamp is divided into functionally independent modules: the lamp holder, the light-emitting assembly, and the transmission mechanism. This segmentation allows each component to perform its specific function independently, with the light-emitting assembly being adjustable while the lamp holder remains stable, resolving the contradiction between adjustability and structural simplicity.
2Adaptability or versatility
If multiple lamp fittings are assembled to achieve different lighting effects, then the lighting effects can be adjusted, but the cost increases and operation becomes inconvenient
Solution Approach 1:
The transmission mechanism provides universal adjustability for the light-emitting assembly, enabling a single lamp to achieve multiple lighting effects through rotation. This eliminates the need for multiple specialized lamp fittings, as one adjustable assembly can replace several fixed fittings, reducing cost and improving operational convenience while maintaining versatility.
Solution Approach 2:
The rotatable light-emitting assembly with transmission mechanism provides dynamic adjustability, allowing users to change lighting effects on-demand by rotating the assembly to different angles. This dynamic capability replaces the need for multiple static fittings, making the lamp adaptable to various lighting scenarios without requiring assembly or purchase of additional components.
3Illumination intensity
If the light source is fixed in position, then the lamp structure is simple, but the light field and illuminance cannot be adjusted
Solution Approach 1:
The light-emitting assembly is designed with rotational freedom around a rotation axis that is non-parallel to the transmission axis, creating a complex spatial motion mechanism. This dynamic configuration allows the light source to reach different spatial positions and orientations, adjusting the light field and illuminance distribution without requiring multiple fixed light sources or complex optical systems.
Solution Approach 2:
The rotation mechanism introduces an additional degree of freedom in three-dimensional space, allowing the light-emitting assembly to move not only radially but also angularly around a non-parallel rotation axis. This multi-dimensional movement capability enables comprehensive adjustment of light field coverage and illuminance intensity from a single structural configuration.

AI summary
A lamp has a base, a transmission mechanism, and multiple light-emitting assemblies. The transmission mechanism is mounted on the base and is rotatable around a transmission axis. The light-emitting assemblies is mounted on the base and is connected to the transmission mechanism. Each light-emitting assembly is rotatable around a rotation axis which is nonparallel with the transmission axis. The light-emitting assemblies can be rotated through driving the transmission mechanism, so as to adjust lighting effects of the light-emitting assemblies and an appearance of the lamp. Not only the lighting effects can be adjusted according to a user's need, but also the appearance of the lamp can be changed to adapt the lamp to the environment where the lamp is disposed, such that the lamp of the present invention can be widely used.
