Solution Overview
Problem
The lighting industry faces challenges with the need to stock a large number of pre-assembled lighting units due to varying LED circuit board sizes and power classes, requiring quick interchangeability, sustainability, and safety, while maintaining high light quality and ease of handling.
Innovation Solution
The inner ring is integrated into a light-directing component, allowing for a reduction in components and enabling pre-assembly, with fastening methods like bayonet connections and self-locking frictional engagement, ensuring stable and tool-free attachment and minimizing light beam loss.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple pre-assembled lighting units are stocked to meet varying LED circuit board sizes and power classes, then customer requirements can be met, but inventory costs and complexity increase significantly
Solution Approach 1:
The connection element is designed with a universal interface that can accommodate multiple LED circuit board sizes and power classes through a standardized mounting structure. The adjustable contact spring mechanism allows the same connection element to work with different board configurations, eliminating the need for multiple specialized units in inventory.
Solution Approach 2:
The connection element is divided into separable components including an outer ring, inner ring, and contact spring assembly. This modular design allows the light-directing component to be pre-assembled with the connection element, creating a standardized module that can be quickly interchanged while maintaining adaptability to different LED configurations.
2Adaptability or versatility
If multiple pre-assembled lighting units are stocked for different configurations, then various luminaire types can be supplied, but assembly time and operational complexity increase
Solution Approach 1:
The light-directing component is pre-assembled with the connection element in a standardized configuration before delivery to the customer. This preliminary assembly creates a ready-to-install module that requires minimal on-site assembly, reducing installation time while maintaining the ability to configure different luminaire types through component selection rather than full pre-assembly.
3Ease of operation
If the inner ring is separated from the light-directing component, then assembly flexibility is maintained, but the number of components and assembly steps increases
Solution Approach 1:
The inner ring is integrated directly into the light-directing component as a unified structure. This merging eliminates the need for separate assembly steps to attach the inner ring, reducing the total component count and simplifying the assembly process while maintaining the functional flexibility needed for different configurations.
4Ease of manufacture
If conventional connection elements are used without light-directing integration, then manufacturing simplicity is maintained, but light efficiency and quality are compromised
Solution Approach 1:
The light-directing component is integrated with the connection element structure, combining optical functionality with mechanical mounting in a single manufactured unit. This integration maintains manufacturing simplicity through standardized production processes while optimizing light efficiency by ensuring proper alignment and minimizing light loss at the connection interface.
