Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminaire systems are costly, time-consuming, and lack flexibility in designing light distribution patterns, as they require specific PCBs and optical elements for each application, making it difficult to adjust light distribution accurately and efficiently for both large and small systems with limited components.
Innovation Solution
A luminaire system with a first support and a movable second support, featuring cut-out regions that allow elastic bending, enabling precise control of optical elements' position relative to light sources, allowing for adjustable light distribution without the need for multiple optical components, achieved through a moving mechanism that alters the position of optical elements relative to the light sources.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If specific PCBs and optical elements are designed for each luminaire application, then the desired light distribution shape is achieved, but the system becomes costly, time-consuming, and requires extensive stock keeping
Solution Approach 1:
The patent applies universality by designing a single standardized PCB structure that can serve multiple luminaire applications. The optical element plate is made adjustable and interchangeable, allowing one PCB design to achieve various light distribution shapes by simply changing the optical element position or type, rather than designing custom PCBs for each application.
Solution Approach 2:
The patent implements dynamics by making the optical element plate adjustable relative to the PCB. The optical elements can be repositioned along the PCB surface using movable mounting structures, allowing dynamic adaptation of light distribution patterns without requiring new PCB designs for different applications.
2Adaptability or versatility
If optical elements are made adjustable on an individual basis, then flexibility in light distribution is improved, but the system becomes relatively complex and accurate control of movement is difficult to achieve
Solution Approach 1:
The patent applies segmentation by dividing the optical element plate into modular units that can be independently adjusted. Each optical element or group of elements can be positioned separately along predefined tracks or guides on the PCB, enabling flexible light distribution control while maintaining manageable system complexity through standardized modular components.
3Device complexity
If a limited amount of different components is used to build both large and small luminaire systems, then stock keeping is reduced, but the ability to achieve accurate light distribution control is limited
Solution Approach 1:
The patent applies parameter changes by enabling the same optical elements to produce different light distribution patterns through positional adjustment. By changing the position parameter of optical elements on the PCB, various light distribution shapes and intensities can be achieved using a limited set of standard components, maintaining manufacturing precision without increasing component variety.
