Rotatable Lamp Modules with Pillar-Groove Hinges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing hanging lamps are limited to either a stable holder or an adjustable hanging wire for installation, lacking the ability to adjust light emitting module angles once installed, which can hinder achieving optimal illumination in small interior spaces.
Innovation Solution
A hanging lamp design featuring rotatable light emitting modules hinged to end frames with convex pillars and curved grooves, allowing for adjustable emission angles and dual installation options using both a holder and a hanging wire.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a holder is used to secure the hanging lamp to the ceiling, then the lamp is more stable and less subject to waggling movement, but the installation position is limited and the height is not adjustable
Solution Approach 1:
The lamp holder is designed with both holder mounting holes and hanging wire mounting holes, enabling the same lamp to be installed using either a holder or a hanging wire. This multi-functional design allows users to choose the appropriate installation method based on their specific needs, whether they prioritize stability or adjustability.
2Adaptability or versatility
If a hanging wire is used to secure the hanging lamp to the ceiling, then the height is adjustable to reach preferable illumination effect, but the lamp is less stable and more subject to waggling movement
Solution Approach 1:
The lamp holder incorporates both holder mounting holes and hanging wire mounting holes, allowing the lamp to be installed using either method. Users can select the hanging wire installation when height adjustability is needed, while accepting reduced stability, or choose the holder installation for maximum stability with fixed position.
3Device complexity
If the light emitting modules are fixed in position, then the structure is simpler, but the emission angle cannot be adjusted once installed
Solution Approach 1:
The light emitting modules are hinged to the end frames through hinge shafts, allowing them to rotate around the hinge shaft axis. This dynamic design enables the emission angle to be adjusted after installation by rotating the modules to different positions, while the hinge structure maintains relative simplicity.
Solution Approach 2:
The lamp is divided into modular components where each light emitting module can be independently rotated and positioned. The modules are connected to the end frames through hinge shafts, allowing individual adjustment of each module's emission angle without affecting the entire lamp structure.
4Device complexity
If the installation position is limited due to small interior room space, then the lamp structure is simpler, but favorable illuminating condition is difficult to achieve
Solution Approach 1:
The hinged light emitting modules can be rotated to different angles to direct light precisely where needed in small spaces. This dynamic positioning capability allows optimal illumination distribution even when the lamp's installation position on the ceiling is constrained by room geometry.
Solution Approach 2:
Each light emitting module can be independently positioned to provide localized illumination in specific areas of the room. This allows different parts of the room to receive appropriate lighting even when the overall lamp position is limited by small interior space.

AI summary
The lamp includes a plurality of light emitting modules each having a protruding pillar at both ends, and a lamp holder with two end frame each having a curved groove. The light emitting modules are rotatably coupled to the lamp holder through a shaft attached to the end frames, such that each protruding pillar is received in one of the curve grooves. Each one of the light emitting modules being rotatable about the shaft with the pillar sliding within the groove, to adjust the direction of emitted light.
