Flush-Mount Solar Panel Hull Integration for Watercraft
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Watercraft, especially lighter ones like kayaks and paddleboards, face challenges with battery power storage due to limited space and buoyancy, leading to drained batteries during offshore trips, which can endanger operators and increase risks during low light or nighttime operations.
Innovation Solution
Integration of solar panels into the hull of watercraft, which are designed to float with the solar panels flush with the surface, providing continuous charging during daylight hours and reducing the need for heavy batteries, along with a rudder to optimize sunlight exposure and a pedal-powered generator for additional energy generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If batteries are used to power watercraft electronics and propulsion, then power storage is provided, but the watercraft weight increases and buoyancy is reduced
Solution Approach 1:
The solar panel is integrated directly into the hull structure of the watercraft, merging the power generation function with the structural component. This eliminates the need for separate battery compartments and reduces overall weight while providing continuous power generation capability.
Solution Approach 2:
The solar panel continuously charges the battery during daylight hours while the watercraft is in use, providing self-sustaining power generation. This self-charging mechanism reduces the initial battery size needed and maintains power storage without adding excessive weight.
2Duration of action of moving object
If larger batteries are installed to ensure sufficient power for offshore trips, then power duration is extended, but the watercraft stability decreases due to reduced buoyancy
Solution Approach 1:
The solar panel is structurally integrated into the hull, combining power generation with the stability-providing hull structure. This eliminates the need for separate heavy battery installations that would compromise stability.
Solution Approach 2:
The solar panel provides continuous charging during daylight hours, ensuring the battery remains charged throughout the trip without needing oversized capacity. This continuous power generation maintains adequate power duration while keeping battery size and weight minimal.
3Use of energy by moving object
If solar panels are added to the watercraft surface, then power generation is increased, but the watercraft hydrodynamics are disrupted
Solution Approach 1:
The solar panel is integrated into the hull structure itself, merging the power generation surface with the hydrodynamic form. This eliminates the need for separate add-on panels that would create drag and disrupt water flow.
Solution Approach 2:
The solar panel is positioned on specific portions of the hull where it can generate power without significantly impacting the overall hydrodynamics. The integration allows for optimized placement that balances power generation with water flow characteristics.

AI summary
A system for providing solar power to a watercraft includes a hull having an outer surface, defining a recess extending inward and offset from the outer surface by a distance, and configured to float on water. The system further includes a solar panel configured to fit within the recess and having a thickness that is substantially equal to the distance such that an outer edge of the solar panel is substantially aligned with the outer surface of the hull.
