Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If different lenses are attached to LED light strips to achieve different light patterns and angles, then light distribution requirements are met, but physical component changes are required which are inconvenient and time-consuming
Solution Approach 1:
The light fixture is divided into multiple independently powered LED arrays, where each array can be controlled separately. This segmentation allows different combinations of arrays to be activated to achieve various light patterns and angles without physically changing components.
Solution Approach 2:
The system enables dynamic adjustment of light distribution by electronically controlling which LED arrays are activated. The light fixture can transition between different lighting configurations in real-time through electrical control rather than mechanical lens changes.
2Adaptability or versatility
If multiple lenses with different heights are provided for different arrays, then different beam angles are achievable, but device complexity increases
Solution Approach 1:
Each LED array is designed with multi-functionality, capable of producing different beam angles and light patterns through electronic control. The same physical array can serve multiple lighting functions by adjusting activation combinations, reducing the need for multiple specialized components.
Solution Approach 2:
The system achieves different beam angles by changing the activation state of LED arrays rather than physically changing lens parameters. By controlling which arrays are powered and at what intensity, the effective light distribution parameters are adjusted without modifying the physical structure.
