Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a light fixture uses multiple light sources arranged in a matrix to enable versatile beam configurations, then the adaptability and versatility are improved, but the device complexity increases
Solution Approach 1:
The light fixture is divided into multiple independent light sources arranged in a matrix pattern, with each source capable of being controlled individually or in groups. This segmentation allows versatile beam configurations (hot-spot, uniform, partial beam) while maintaining manageable complexity through modular design and systematic control grouping.
2Adaptability or versatility
If an optical mixing element is introduced to adjust beam uniformity, then the adaptability is improved, but the device complexity and manufacturing cost increase
Solution Approach 1:
The optical mixing element is made movable along the optical axis between different positions (first position for hot-spot configuration, second position for uniform configuration). This dynamic positioning allows the system to switch between different beam patterns without requiring multiple fixed optical systems, thereby reducing overall device complexity while maintaining high adaptability.
3Measurement precision
If precise control of optical element position is implemented to switch between beam configurations, then the measurement precision is improved, but the device complexity increases
Solution Approach 1:
The control system uses pre-programmed position commands that correspond to predetermined optical element positions for different beam configurations. Instead of requiring complex real-time calculation and adjustment mechanisms, the system employs stored control data (copies of optimal settings) that simplifies the control architecture while maintaining precise positioning for hot-spot and uniform beam modes.
