Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If LED lights are used in laser lighting systems, then the system can operate without a laser unit, but the color rendering is insufficient and the lights appear washed out
Solution Approach 1:
The patent combines LED lights with optical fibers to create a hybrid lighting system. The LED unit provides the light source while the optical fibers transmit and enhance the light, merging the simplicity of LED operation with the superior color rendering of optical fiber-based lighting.
Solution Approach 2:
The optical fiber acts as an intermediary between the LED light source and the final illumination. It receives light from the LED and transforms it into high-quality, vibrant lighting output, mediating between the simple LED source and the desired high-color-rendering performance.
2Device complexity
If conventional lighting methods are used, then the system structure remains simple, but the lighting cannot penetrate water effectively
Solution Approach 1:
The patent replaces conventional mechanical lighting systems with an optical fiber-based system. The optical fibers are specifically designed to transmit light effectively through water, substituting traditional lighting mechanisms with an optical transmission medium that overcomes the water penetration barrier.
Solution Approach 2:
The optical fibers are designed with specific optical parameters (transmission properties, wavelength characteristics) that enable effective light penetration through water. By changing the optical parameters of the light transmission medium, the system achieves water penetration capability without increasing structural complexity.
3Illumination intensity
If laser lights are used, then vibrant colors and water penetration are achieved, but the system becomes expensive and complex
Solution Approach 1:
The patent creates a simplified copy of the laser lighting effect using optical fibers and LED lights. Instead of using actual laser light sources, the system copies the desirable optical properties (vibrant colors, water penetration) through optical fiber transmission, achieving similar effects with simpler, less expensive components.
Solution Approach 2:
The system replaces expensive laser units with more economical LED lights and optical fibers. The optical fiber-based approach uses cheaper, more durable components that can be easily replaced if needed, eliminating the need for expensive laser hardware while maintaining the desired optical performance.
4Illumination intensity
If optical fibers are used to transmit light, then water penetration and color vibrancy are improved, but the system becomes more complex
Solution Approach 1:
The optical fibers serve multiple functions: they transmit light, enable water penetration, and maintain color vibrancy. By making the optical fiber system multi-functional, the patent achieves water penetration capability without proportionally increasing system complexity, as the same components handle multiple performance requirements.
