Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If conventional LED lighting fixtures are used, then general illumination is provided, but precise control over beam angles and field angles is not achieved
Solution Approach 1:
The lens is divided into three distinct functional segments: a collimator portion for initial light direction control, an air gap for light separation and angle definition, and a core portion for final beam shaping. Each segment independently contributes to achieving the precise beam angle and field angle control required, while allowing modular design and manufacturing.
2Ease of operation
If a narrow beam angle is achieved through lens design, then lighting control is improved, but manufacturing complexity increases
Solution Approach 1:
Different portions of the lens structure have specialized geometries optimized for their specific functions: the collimator has a first geometry for initial collimation, the air gap provides a controlled separation distance, and the core has a second geometry for final beam shaping. This local optimization allows each portion to be manufactured using appropriate techniques while achieving precise overall lighting control.
3Reliability
If precise beam angle control is implemented, then lighting effectiveness is enhanced, but structural complexity increases
Solution Approach 1:
The air gap serves as an intermediary element between the collimator and the core, providing a controlled space that allows light to transition between the two optical components. This intermediary structure enables precise beam angle control by defining the optical path and separating the functions of collimation and beam shaping, while maintaining a manageable overall structure.
