Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing luminaire head assemblies are not modular, limiting their adaptability to different configurations and applications, requiring multiple components and molds for various orientations and illumination needs, which increases manufacturing costs and reduces modularity.
Innovation Solution
A modular luminaire head assembly system using identical bodies and supports with interchangeable components such as skirts and protection and connection assemblies, allowing for easy adjustment between side-entry and post-top configurations, and enabling customization of light effects and distributions without the need for new housings.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If luminaire heads are designed for specific configurations (post-top or side-entry), then the structural integrity and performance for that configuration is optimized, but the number of different components and molds increases, reducing manufacturing efficiency
Solution Approach 1:
The patent applies universality by designing a single luminaire head body that can serve multiple configurations (post-top and side-entry). The body includes multiple mounting interfaces and attachment points that allow it to be adapted to different pole orientations and mounting methods, eliminating the need for separate dedicated components for each configuration type.
Solution Approach 2:
The luminaire head is segmented into modular components including the body, photometric unit, skirt, and various attachment mechanisms. This segmentation allows individual components to be independently manufactured and then assembled in different configurations, enabling the same body to serve multiple purposes while maintaining configuration-specific optimization.
2Adaptability or versatility
If different components are used for different configurations and applications, then the adaptability to specific applications is improved, but the device complexity and number of components increases
Solution Approach 1:
The luminaire head body incorporates universal mounting features including multiple attachment points, adjustable brackets, and standardized interfaces that enable the same component to be adapted to various applications (street lighting, pathway lighting, architectural lighting) without requiring application-specific custom components.
Solution Approach 2:
The design includes adjustable and reconfigurable elements such as adjustable mounting brackets, rotatable photometric units, and flexible skirt attachments that allow the luminaire head to be dynamically reconfigured for different applications and orientations, providing adaptability without increasing component count.
3Ease of manufacture
If luminaire heads are designed with fixed configurations, then the manufacturing cost per configuration is reduced, but the ability to upgrade and modify existing installations is limited
Solution Approach 1:
The modular segmentation of the luminaire head into interchangeable components (photometric unit, skirt, mounting mechanisms) allows individual components to be upgraded or replaced without replacing the entire assembly. The standardized interfaces and attachment points enable cost-effective manufacturing of individual upgrade components while maintaining upgradeability.
4Adaptability or versatility
If multiple specialized luminaire heads are maintained in stock for different applications, then the suitability for specific applications is improved, but the inventory complexity and manufacturing costs increase
Solution Approach 1:
By maintaining a core inventory of universal luminaire head bodies with standardized interfaces and mounting features, the system can serve multiple applications by combining the universal body with different photometric units, skirts, and attachment components. This approach reduces the total number of components that need to be stocked while maintaining application-specific suitability through modular combinations.
