Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing floating subsurface illumination systems for pools and bodies of water face challenges in providing reliable, self-contained energy and stability, especially in turbulent conditions, and require frequent replacement of energy sources and lack effective waterproofing to prevent water ingress.
Innovation Solution
A leak-proof enclosure with a rechargeable DC electric source and LED light source, where the enclosure's design allows for adjustable dimensions and placement of subsystems to enhance stability and facilitate recharging, ensuring the center of gravity is near the lowest point of the narrower lower portion for increased stability and efficient energy use.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a floating subsurface illumination system uses a rechargeable energy source, then operation costs are reduced by eliminating frequent replacement, but the system requires waterproofing to prevent water ingress into electrical subsystems
Solution Approach 1:
The patent separates the electrical subsystems from the aquatic environment by extracting them into a dedicated waterproof enclosure. The rechargeable battery and LED components are completely isolated from water contact through this enclosed structure, allowing reliable operation in wet environments without water ingress risks.
Solution Approach 2:
The waterproof enclosure acts as an intermediary barrier between the electrical subsystems and the aquatic environment. This protective shell enables the system to function in water-related applications by mediating the interaction between electrical components and moisture, preventing harmful water contact while allowing light transmission.
2Stability of the object's composition
If the enclosure uses a wider upper portion and narrower lower portion, then stability against turbulence is improved, but the system complexity increases due to tailored dimensions
Solution Approach 1:
The enclosure employs asymmetric geometry with a wider upper portion and narrower lower portion, creating an unstable base that intentionally lowers the center of gravity. This asymmetric design provides stability against turbulence by ensuring the system rights itself when tilted, rather than capsizing, while maintaining manageable structural complexity.
Solution Approach 2:
The patent addresses stability by transitioning from considering only horizontal dimensions to incorporating vertical dimension considerations. By adjusting the height and vertical positioning of components within the enclosure, the system achieves enhanced stability through three-dimensional configuration rather than relying solely on base width.
3Use of energy by moving object
If LED light sources are used, then light intensity per watt is improved, but the system requires precise waterproofing to protect electrical components
Solution Approach 1:
The patent merges the LED light source, rechargeable battery, and control electronics into a single integrated waterproof enclosure. This consolidation allows for comprehensive sealing of all electrical components together, simplifying the waterproofing requirement from multiple separate sealed connections to a single unified enclosure, thereby reducing manufacturing precision demands.
