Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Marine docks and pilings pose safety hazards at night due to invisibility in waterways, and traditional lighting solutions are costly and logistically challenging, especially in areas where electrical power is not readily available.
Innovation Solution
A solar-powered lighted piling cap equipped with high-powered LED lights, a sealed lithium polymer battery, and a dusk-to-dawn sensor, providing 360-degree illumination without the need for electrical wiring, constructed from durable, impact-resistant materials to withstand harsh marine environments.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If traditional electrical lighting systems are installed on docks and pilings, then illumination is provided, but installation cost and complexity increase due to wiring requirements
Solution Approach 1:
The patent extracts the lighting function from the dock structure itself and implements it through removable, self-contained LED light fixtures that can be independently installed and removed without modifying the dock's electrical infrastructure. This eliminates the need for complex wiring while providing effective illumination.
Solution Approach 2:
The patent replaces the electrical wiring system with a mechanical mounting system using clamp-style fixtures that attach to pilings and posts. This mechanical approach substitutes the complex electrical installation with a simple mechanical attachment that requires no wiring, achieving the same lighting function with reduced complexity.
2Illumination intensity
If electrical wiring is installed near water, then lighting is provided, but corrosion and safety hazards increase
Solution Approach 1:
The patent extracts the lighting function from water-prone areas by mounting lights on vertical pilings above the water line. This positioning removes the lighting system from direct water exposure, eliminating corrosion risks while maintaining effective illumination of the dock area.
Solution Approach 2:
The patent replaces electrical wiring (which is vulnerable to water corrosion) with a mechanical clamp-style mounting system. This mechanical approach eliminates the need for electrical conduits and wiring near water, removing the corrosion hazard entirely while providing the same lighting function through weather-resistant LED fixtures.
3Illumination intensity
If lighting systems are installed on remote docks, then visibility is improved, but installation and maintenance cost increase due to logistical distance
Solution Approach 1:
The patent extracts the lighting function into self-contained, plug-and-play fixtures that require no electrical infrastructure. This allows independent installation on remote docks without needing to run wiring from shore or existing power sources, dramatically reducing installation and maintenance costs for remote locations.
Solution Approach 2:
The patent replaces complex electrical installation with simple mechanical mounting using clamp-style fixtures. This mechanical approach allows anyone to install lights on remote docks without requiring licensed electricians or complex wiring infrastructure, reducing both installation and maintenance costs for remote locations while providing effective nighttime visibility.
4Illumination intensity
If multiple LED bulbs are used, then illumination coverage is improved, but device complexity and power consumption increase
Solution Approach 1:
The patent segments the lighting system into multiple independent LED bulb modules that can be individually installed in clamp-style fixtures. Each bulb is a separate, replaceable component that provides focused illumination in specific directions, allowing coverage of larger areas through strategic placement rather than increasing the complexity of single fixtures.
