Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If incandescent light bulbs are used in underwater fixtures, then bright illumination is achieved, but electrical safety risks increase due to high voltage connections in water
Solution Approach 1:
The patent replaces the traditional incandescent bulb mechanical-electrical system with an LED-based system operating at low voltage (5V). This substitution eliminates the need for high-voltage electrical connections in the underwater environment, thereby removing the electrical safety hazard while maintaining illumination functionality through electro-optical conversion of LEDs
Solution Approach 2:
The patent changes the operating voltage parameter from standard high voltage (110V/220V) to low voltage (5V) for the underwater lighting system. This parameter change fundamentally alters the safety characteristics of the system, allowing electrical components to operate safely in the conductive aquatic environment while still providing sufficient light output through efficient LED technology
2Object-affected harmful factors
If LED lighting assemblies are used, then electrical safety is improved through low voltage operation, but brightness intensity decreases compared to incandescent bulbs
Solution Approach 1:
The patent combines multiple red, green, and blue LEDs in an array configuration within a single fixture. By merging these different colored LEDs and controlling them in various combinations, the system achieves both high brightness intensity and full color variability (256,000 colors) while operating safely at low voltage, overcoming the brightness limitation of individual low-power LEDs
3Adaptability or versatility
If manual color adjustment is implemented by replacing bulbs or lenses, then color variety is achieved, but operational complexity increases and continuous color variation is not possible
Solution Approach 1:
The patent implements dynamic color control through electronic means rather than static manual adjustment. The controller can vary the intensity and combination of red, green, and blue LEDs in real-time, enabling continuous color variation and transitions without requiring physical intervention. This dynamic electronic control allows the lighting system to adapt colors programmatically or via remote control
Solution Approach 2:
The patent incorporates a microprocessor-based controller that enables the lighting system to operate autonomously with pre-programmed color sequences, patterns, and transitions. The system can self-regulate color changes without manual intervention, and users can remotely control or program color variations, eliminating the need for physical bulb or lens replacements to achieve color variety
4Illumination intensity
If incandescent lamps with high intensity are used, then illumination brightness is improved, but pool surface imperfections become more visible due to light diffusion
Solution Approach 1:
The patent employs multiple individual LEDs arranged in an array rather than a single high-intensity point source. Each LED emits light in a specific direction with controlled intensity, creating localized illumination zones. This distributed light source approach provides even illumination across the pool surface without the harsh diffusion patterns of incandescent bulbs, thereby reducing the visibility of surface imperfections while maintaining overall brightness
