Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a fixed reflector geometry is used, then the manufacturing precision and structural simplicity are improved, but the adaptability and flexibility in light emission are worsened
Solution Approach 1:
The system is divided into two independent functional modules: a fixed reflector arrangement for structural simplicity and an adjustable optical arrangement for light guidance. This segmentation allows each component to optimize its specific function - the reflector maintains fixed geometry for ease of manufacture while the optical arrangement provides adjustable asymmetry for flexible light emission patterns.
Solution Approach 2:
The optical arrangement is designed to be adjustable relative to the fixed reflector, enabling dynamic modification of light guidance without changing the reflector geometry. This allows the system to adapt light emission patterns to different application requirements while maintaining the structural simplicity of the fixed reflector design.
2Adaptability or versatility
If an adjustable optical arrangement is added, then the adaptability and flexibility in light distribution are improved, but the device complexity increases
Solution Approach 1:
The optical arrangement acts as an intermediary element between the light source and the fixed reflector. This mediator component enables flexible light guidance and asymmetric illumination patterns without requiring modifications to the reflector structure itself, thus adding adaptability while isolating the complexity to a single adjustable module rather than the entire system.
3Illumination intensity
If asymmetric light guidance is implemented, then the targeted light distribution is improved, but the scattering losses increase
Solution Approach 1:
The optical arrangement enables controlled modification of light parameters (direction, asymmetry, distribution pattern) to achieve targeted illumination. By adjusting the optical arrangement's position and orientation, the system optimizes light guidance to minimize scattering losses while achieving the desired asymmetric light distribution patterns on the target surface.
