Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If conventional solar powered LED lawn lights use simple illumination design, then they achieve basic lighting function, but they lack aesthetically pleasing design and varied lighting effects
Solution Approach 1:
The LED lighting fixture is divided into multiple LED lamps (first, second, third, and fourth LED lamps) arranged in a geometric pattern, each contributing to different aspects of the lighting effect. This segmentation allows for varied lighting effects while maintaining a structured design approach.
Solution Approach 2:
The lamp shade incorporates an uneven surface with specific optical properties that differ from flat surfaces. This local quality enhancement creates refraction effects that add aesthetic value and varied lighting patterns without requiring complete redesign of the entire fixture.
2Adaptability or versatility
If LED lamps are arranged in geometric pattern with controller, then varied lighting effects are created, but device complexity increases
Solution Approach 1:
The controller enables dynamic adjustment of luminous intensity for different LED lamps, allowing the lighting fixture to adapt to various lighting scenarios. This dynamic control provides versatility in lighting effects while using a standardized controller component.
Solution Approach 2:
The combination of geometric LED arrangement with asymmetric uneven surface on the lamp shade creates visually interesting lighting patterns. The asymmetry in surface texture works with the symmetric geometric arrangement to produce varied refraction effects.
3Illumination intensity
If lens is added to concentrate light, then illumination intensity is improved, but device complexity and number of components increase
Solution Approach 1:
The lens performs preliminary light concentration before light reaches the LED lamps and uneven surface. This preliminary action of concentrating light ensures maximum utilization of light energy and enhances the subsequent refraction effects without requiring additional active components.
Solution Approach 2:
The lens acts as an intermediary optical element between the light source and the LED lamps, concentrating and directing light in a controlled manner. This intermediary component simplifies the overall system by providing a passive optical solution rather than requiring active light control mechanisms.
4Shape
If uneven surface lamp shade is used for refraction effects, then aesthetic appeal is improved, but manufacturing precision requirements increase
Solution Approach 1:
The lamp shade deliberately incorporates an uneven asymmetric surface rather than追求 perfect uniformity. This asymmetric design is intentionally manufactured to create refraction effects, transforming what could be a manufacturing tolerance issue into a deliberate aesthetic feature.
Solution Approach 2:
The uneven surface of the lamp shade creates variations in light refraction that produce different lighting patterns and visual effects. While not directly changing color, the surface variations create perceived color and brightness variations through optical refraction.
