Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If 360 LEDs are arranged on the outer ring periphery to achieve a luminous effect, then the luminous effect is improved, but the device complexity and production cost increase
Solution Approach 1:
The patent introduces light-guiding ribs as intermediary elements between the LEDs and the outer ring periphery. These ribs guide light from a small number of LEDs arranged on the central disc portion to the outer ring periphery, achieving uniform illumination without requiring 360 LEDs. This intermediary structure resolves the contradiction by enabling the luminous effect with fewer components.
Solution Approach 2:
The patent replaces the mechanical arrangement of numerous LEDs with an optical guidance system. Instead of mechanically positioning 360 LEDs around the periphery, the invention uses light-guiding ribs made of light-guide material to transmit and distribute light optically, thereby achieving the same illumination effect with fewer components and reduced structural complexity.
2Illumination intensity
If 360 LEDs are arranged on the outer ring periphery to achieve a luminous effect, then the luminous effect is improved, but the production cost increases
Solution Approach 1:
The light-guiding ribs serve as cost-effective intermediaries that enable uniform illumination around the outer ring using only a handful of LEDs. This approach significantly reduces the bill of materials compared to arranging 360 LEDs, thereby lowering production cost while maintaining the desired luminous effect.
Solution Approach 2:
The light-guiding ribs act as optical copies or replicas of the light source, distributing the light from a small number of LEDs to multiple locations around the outer ring periphery. This copying mechanism allows the system to achieve the appearance of many light sources while actually using only a few, thus reducing production cost.
3Illumination intensity
If 360 LEDs are arranged on the outer ring periphery, then the luminous effect is improved, but the practicability decreases
Solution Approach 1:
The light-guiding ribs provide a practical solution by enabling the frisbee to achieve uniform illumination with fewer LEDs, which simplifies the overall structure and improves maintainability. This intermediary approach makes the product more adaptable and versatile for practical use, as fewer components mean easier assembly, maintenance, and potential customization.
