Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional single light sources are used, then the device complexity is low, but the adaptability to different surface materials and features is insufficient
Solution Approach 1:
The lighting system is divided into multiple individually addressable light sources (at least ten) arranged in specific patterns, allowing selective activation of different light sources for different inspection scenarios. Each light source can be controlled independently to optimize lighting for specific surface materials and features.
Solution Approach 2:
The lighting system is designed to provide multiple lighting functions through a single device by combining multiple light sources with different color temperatures (e.g., 6504K, 3000K, 2000K) and control capabilities, enabling the system to adapt to various inspection requirements without needing separate specialized light sources.
2Adaptability or versatility
If fixed lighting configurations are used, then the ease of operation is high, but the adaptability to different environments and inspection requirements is limited
Solution Approach 1:
The lighting system incorporates adjustable diffusers and individually addressable light sources that can be dynamically controlled to change lighting patterns, intensity, and distribution. This dynamic capability allows the system to adapt to different inspection environments and requirements while maintaining ease of operation through automated or semi-automated control.
3Reliability
If multiple individually addressable light sources are used, then the lighting quality and adaptability are improved, but the device complexity increases
Solution Approach 1:
Multiple individually addressable light sources are integrated into a single unified lighting system with common control mechanisms. The light sources are combined in specific geometric arrangements (e.g., circular, rectangular patterns) and share common power supply and control electronics, reducing overall system complexity while maintaining the benefits of individual control.
