Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional cylindrical tube lights have limitations in flexibility and adaptability for illuminating various areas, as they are fixed in a vertical position and lack the ability to adjust their lighting angle or arrangement.
Innovation Solution
A lamp design featuring pivotably connected lighting elements that form a cylindrical or polygonal lighting surface, allowing for adjustable positions and angles, including a base element with pivotable LEDs that can be folded to create a 360° lighting surface, and a holding device with a displaceable connecting element and fixing mechanism for secure positioning.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional cylindrical tube lights are used with fixed vertical position, then simple structure is maintained, but flexibility and adaptability for illuminating various areas is limited
Solution Approach 1:
The lamp is divided into multiple individual lighting elements that can be independently positioned. Each lighting element can be separately adjusted to different angles and orientations, allowing the system to adapt to various illumination requirements while maintaining a relatively simple overall structure.
Solution Approach 2:
The lighting elements are made dynamically adjustable through pivotable connections to the base element. This allows the lamp to change its configuration from a fixed cylindrical shape to various dynamic arrangements, enabling flexible illumination of different areas while keeping the structural design straightforward.
2Ease of operation
If lighting elements are made fixed in vertical position, then manufacturing simplicity is maintained, but ability to adjust lighting angle or arrangement is lost
Solution Approach 1:
By segmenting the lamp into individual adjustable lighting elements rather than a single fixed structure, the patent enables easy adjustment of lighting angles and arrangements. Each element can be independently positioned without complicating the manufacturing process, as each component remains relatively simple.
Solution Approach 2:
The pivotable connection mechanism provides dynamic adjustability for lighting elements, allowing users to easily change lighting angles and arrangements. This dynamic capability is achieved through simple mechanical joints that are straightforward to manufacture and assemble.
3Adaptability or versatility
If pivotable lighting elements are added to base element, then illumination flexibility is improved, but structural complexity increases
Solution Approach 1:
The lamp structure is segmented into a base element and multiple independent lighting elements with pivotable connections. This segmentation allows each component to remain structurally simple while the overall system gains illumination flexibility through the ability to independently position each lighting element.
4Manufacturing precision
If holding device with displaceable connecting element is implemented, then positioning precision is improved, but device complexity increases
Solution Approach 1:
A holding device with a displaceable connecting element acts as an intermediary mechanism between the base element and lighting elements. This intermediary component enables precise positioning of lighting elements through controlled displacement, while the modular design keeps the overall device complexity manageable.

AI summary
A luminaire comprises a base element (10) and several light elements (12) pivotably connected to the base element (10). In a folded position, the light elements (12) form a light surface that is at least partially cylindrical. In particular, at least one sliding element (42, 50) is provided for pivoting the light elements.
