Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional light sources and reflector designs are used in obstruction lights, then the device can be manufactured with simpler materials and processes, but the light efficiency is low and the beam spread is wide
Solution Approach 1:
The reflector is designed with a parabolic curvature profile that precisely focuses light from the LED array into a narrow beam. The curved surface geometry optimizes light reflection angles to achieve high directional intensity while maintaining manufacturability through standard forming processes.
Solution Approach 2:
The patent transitions from traditional incandescent or fluorescent light sources to LED technology, fundamentally changing the light generation parameters. This enables higher light efficiency and longer lifespan while allowing for more precise optical control through the parabolic reflector design.
2Reliability
If durable materials meeting IP66 standards are used to ensure reliability in harsh environments, then the obstruction light can withstand dust and water, but the cost increases
Solution Approach 1:
The housing incorporates sealed designs with gaskets and protective coatings that provide IP66 dust and water resistance. These thin film barrier layers protect internal components without requiring厚重的 materials, maintaining cost-effectiveness while achieving the required environmental durability.
3Illumination intensity
If arrays of LED light sources are used to achieve high light intensity and narrow beam spread, then the light efficiency improves, but the device complexity increases
Solution Approach 1:
The light source is divided into multiple LED elements arranged in an array within the parabolic reflector. Each LED contributes to the overall beam intensity, and the segmented structure allows for modular assembly and replacement, reducing operational complexity despite the increased number of components.
