Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If a diffuser is used with LEDs to direct light in defined directions, then light directionality is improved, but the design versatility and effectiveness are limited
Solution Approach 1:
The diffuser is divided into multiple distinct regions (first region with asymmetrical optical elements, second region with symmetrical optical elements, third region with interspersed elements) that can independently direct light in different patterns, enabling both defined light directionality and design versatility simultaneously
Solution Approach 2:
Different regions of the diffuser have different optical element configurations tailored to specific lighting requirements - asymmetrical elements in some regions for directional control, symmetrical elements in others for uniform distribution, creating localized optical qualities that achieve both directionality and versatility
2Manufacturing precision
If multiple optical elements are integrated into the diffuser, then light pattern definition and homogenization are improved, but manufacturing complexity increases
Solution Approach 1:
Multiple optical elements with different functions (asymmetrical, symmetrical, interspersed) are merged into a single integrally formed diffuser component, achieving precise light pattern definition while simplifying manufacturing by eliminating the need to assemble separate optical components
Solution Approach 2:
The diffuser serves multiple functions simultaneously - directing light in defined directions, homogenizing light patterns, and creating distinct visual effects through different optical element regions, all within a single universal component that reduces overall system complexity
