Innovation Solution
A flexible supporting structure with adjustable connections, including rods and connectors, is designed to securely attach to a funnel-shaped reflector, allowing for compatibility with multiple light sources and reflector sizes, and includes pivotable rods and variable socket spacing for enhanced adaptability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a fixed supporting structure is used with a reflector, then the reflector is stable and prevented from collapsing, but the lighting device cannot accommodate various light sources and reflector types
Solution Approach 1:
The supporting structure is divided into multiple separate rods (first rods, second rods) and connectors that can be independently assembled and configured. This segmentation allows the structure to be adapted to different light source sizes and reflector types while maintaining stability, as each rod can be positioned and connected according to specific requirements.
Solution Approach 2:
The supporting structure incorporates adjustable and pivotable connections between rods and connectors, enabling dynamic reconfiguration. The rods can be pivoted and repositioned to accommodate different light source configurations, transforming a static structure into a dynamic one that adapts to various lighting applications without requiring complete structural redesign.
2Adaptability or versatility
If a single supporting structure design is used, then manufacturing is simplified, but flexibility to accommodate different light source sizes is reduced
Solution Approach 1:
The supporting structure uses universal connectors and standardized rod designs that can serve multiple functions with different reflector types and light source configurations. The same basic components (rods, connectors, sockets) can be assembled in various arrangements to support different reflector sizes, eliminating the need for multiple specialized supporting structure designs while maintaining ease of manufacture through component standardization.
3Stability of the object's composition
If rigid connections are used in the supporting structure, then structural stability is improved, but adaptability and ease of assembly for different configurations is reduced
Solution Approach 1:
The supporting structure employs pivotable connections and adjustable joints that allow easy assembly and reconfiguration during setup, then maintain stability during operation. The connections can be easily adjusted to achieve the desired configuration for different light sources, yet provide sufficient rigidity once positioned to ensure reflector stability during use.
Solution Approach 2:
The supporting structure allows changes in geometric parameters (rod angles, connector positions, spacing) during assembly to accommodate different configurations, while maintaining structural integrity. The ability to adjust these parameters during setup provides ease of operation, while the overall structural design ensures stability is achieved once the configuration is established.
