Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If unique lens designs are created for specific lighting purposes, then beam shaping performance is optimized, but logistics and part management complexity increases
Solution Approach 1:
The patent applies universality by designing a single lens that can be used across multiple fixture types and light source configurations. The lens incorporates an array of protrusions with varying angles and spacings that can adapt to different lighting requirements, eliminating the need for multiple specialized lens designs and simplifying inventory management.
Solution Approach 2:
The patent applies local quality by creating protrusions with different local properties (varying angles, spacings, and heights) within a single lens structure. This allows different regions of the lens to optimize for specific beam shaping needs while maintaining a unified component design that can serve multiple purposes.
2Adaptability or versatility
If multiple specialized lens designs are maintained, then specific lighting requirements are met, but manufacturing complexity and costs increase
Solution Approach 1:
The patent reduces manufacturing complexity by consolidating multiple lens designs into a single universal lens that can be produced using one mold or manufacturing process. The array of protrusions with varying characteristics is integrated into one component, eliminating the need to manufacture, inventory, and manage multiple specialized lens types.
3Device complexity
If a single lens design is used across various fixtures, then logistics are simplified, but beam shaping adaptability may be compromised
Solution Approach 1:
The patent maintains beam shaping adaptability within a single lens design by incorporating protrusions with locally varied properties. Different regions of the lens have protrusions with different angles, spacings, and heights, allowing the lens to adapt to various lighting requirements while remaining a single universal component that simplifies logistics.

Data Source
AI summary
A lens for a light fixture has a plurality of protrusions for spreading a beam of light from a light source of the light fixture. The protrusions enable the lens to be used in different light fixtures while providing similar beam characteristics. In some configurations, the lens comprises texturing to further shape the beam.
