Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the focal length of the lens is adjusted to change the beam angle, then the beam angle can be changed, but the structure becomes complex and manufacturing cost increases
Solution Approach 1:
The lens is divided into multiple independent lens elements (first lens element, second lens element, third lens element) with different focal lengths. Each lens element can be independently selected and positioned, allowing beam angle adjustment without requiring a complex variable focal length lens mechanism. This segmentation simplifies the overall structure while maintaining adaptability.
Solution Approach 2:
The lens assembly is configured to be movable relative to the light source assembly, allowing dynamic selection of different lens elements. The movable lens assembly can shift position to bring different lens elements into the optical path, enabling real-time beam angle adjustment without complex mechanical mechanisms.
2Adaptability or versatility
If the focal length of the lens is adjusted to change the beam angle, then the beam angle can be changed, but manufacturing cost increases
Solution Approach 1:
The lens system uses multiple discrete lens elements instead of a single complex variable focal length lens. Each lens element can be manufactured independently using standard lens manufacturing processes, reducing overall manufacturing cost while providing multiple beam angle options.
Solution Approach 2:
The lens assembly serves multiple functions: it acts as both a protective cover and an optical element. The same lens assembly structure is used across different lighting scenarios by simply changing which lens element is positioned in the optical path, reducing the need for multiple specialized components.
3Adaptability or versatility
If multiple lighting scenarios are supported with different beam angles and color temperatures, then adaptability improves, but device complexity increases
Solution Approach 1:
The lighting system is divided into independent modules: light source assembly with multiple color temperature LEDs, lens assembly with multiple beam angle lens elements, and control assembly. This modular segmentation allows each module to be optimized independently and simplifies the overall device structure while supporting multiple lighting scenarios.
Solution Approach 2:
The lens assembly and light source assembly are designed to work together in multiple configurations. The same physical assemblies support both spot lighting and flood lighting modes, as well as multiple color temperature combinations, reducing the need for separate dedicated components for each lighting scenario.
4Manufacturing precision
If accurate beam angle adjustment is achieved, then illumination precision improves, but structure complexity increases
Solution Approach 1:
The lens assembly is designed to be movable, allowing precise positioning of different lens elements. The movability enables accurate alignment of each lens element with the light source, achieving precise beam angle control without requiring complex adjustment mechanisms. The simple movable design maintains structural simplicity while improving precision.
