Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If conventional lighting fixtures are assembled with fixed components, then structural stability is improved, but adaptability to different applications deteriorates
Solution Approach 1:
The patent implements adjustable rod positioning mechanisms that allow the lighting fixture to dynamically change its configuration. The rods can be repositioned along the flexible LED circuit board to different locations, enabling the same physical fixture to adapt to various lighting applications while maintaining structural integrity through controlled mechanical adjustments.
Solution Approach 2:
The lighting fixture is divided into modular components including separate rods, flexible LED circuit board segments, and adjustable mounting mechanisms. This segmentation allows individual components to be repositioned and reconfigured independently, providing adaptability while each component maintains its structural stability.
2Adaptability or versatility
If rod positioning is made adjustable to enable customization, then adaptability is improved, but device complexity increases
Solution Approach 1:
The adjustable rod positioning system serves multiple functions: it defines the shape of the flexible LED circuit board, determines LED spacing, controls light distribution patterns, and adapts to different mounting configurations. This multi-functionality reduces the need for separate adjustment mechanisms for each parameter, thereby limiting the increase in overall device complexity.
3Adaptability or versatility
If LED spacing is varied to achieve different light distribution patterns, then light distribution customization is improved, but manufacturing precision requirements increase
Solution Approach 1:
The flexible LED circuit board is pre-fabricated with LEDs mounted at specific spacings before being installed in the fixture. This preliminary action allows for precise LED placement during manufacturing, while the subsequent adjustable rod positioning provides post-manufacturing customization of light distribution patterns without requiring additional precision in the LED mounting process.

AI summary
Techniques are disclosed for designing light fixtures for flexible LED circuit boards. The flexible LED circuit boards include an array of LED packages and the surface of the flexible circuit boards is highly reflective. A flexible LED circuit board may be shaped to conform to a rigid preform and the preform may be concave, convex, corrugated, or have any other custom shape. The shape of the preform, as well as the location of the LEDs within the flexible LED circuit may determine the light distribution of the light fixture. Alternatively, the lighting fixture may have multiple rods held in place with side plates and a flexible LED circuit board may be woven between the rods. A set of hole patterns in the side plates determine the location of the rods and the rods will determine the shape of the flexible LED circuit.
