Solution Overview

Problem

Floating solar energy systems, particularly pontoons, face durability issues due to wind, waves, water currents, UV radiation, and saltwater wear, leading to potential system failure and high repair costs.

Innovation Solution

A pontoon design combining a non-floating structural element made of solidified material, such as reinforced concrete, with a floating element like expanded polystyrene, where the structural element is moulded around the float to create a durable and stable structure with a protected cavity for the float, enhancing strength and reducing mechanical handling during manufacturing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a floating solar energy system uses traditional pontoons made of multiple parts, then the system can be assembled, but the pontoons are vulnerable to wear and damage from wind, waves, water currents, UV radiation, and saltwater

Engineering Contradiction:
Improvedurability of pontoonVSAvoidwear from environmental factors
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines the float and structural element into a single integrated pontoon component. The float is positioned in a cavity of the structural element, creating a unified structure that eliminates interfaces between separate parts. This integration reduces vulnerability to wear and damage by removing potential failure points at connection interfaces, while still providing protection against environmental factors like wind, waves, water currents, UV radiation, and saltwater.

Inventive Principle:
Principle #5Merging (Combining)

2Strength

If the structural element is made strong and durable to resist environmental wear, then the pontoon stability improves, but the manufacturing complexity and mechanical handling requirements increase

Engineering Contradiction:
Improvestrength of structural elementVSAvoidmanufacturing process complexity
Core Design Contradiction:
StrengthVSEase of manufacture

Solution Approach 1:

The patent positions the float in the cavity of the structural element before the concrete material is poured and solidified. This preliminary positioning allows the float to be integrated into the structural element during the manufacturing process itself, rather than requiring complex assembly operations after manufacturing. The structural element is moulded around the float, creating a strong integrated structure while simplifying manufacturing by performing the integration action during the forming process.

Inventive Principle:
Principle #10Preliminary action

3Weight of moving object

If the float is exposed to provide sufficient buoyancy, then the floating capability is maximized, but the float becomes more vulnerable to wear and damage from environmental factors

Engineering Contradiction:
Improvebuoyancy of pontoonVSAvoidresistance to wear and damage
Core Design Contradiction:
Weight of moving objectVSReliability

Solution Approach 1:

The patent nests the float within a cavity of the structural element. The float is positioned in the cavity such that it provides sufficient buoyancy for the pontoon to float on water surfaces, while the structural element cavity protects the float from direct exposure to environmental wear factors. The structural element acts as a protective shell around the float, allowing the float to maintain its buoyancy function while being shielded from wind, waves, water currents, UV radiation, and saltwater damage.

Inventive Principle:
Principle #7Nested doll (Nesting)
