Solution Overview

Problem

Existing floating photovoltaic installations face challenges with complex and costly logistics due to the need for intricate support structures that are not suitable for floating applications, require significant transportation and assembly efforts, and do not effectively manage panel shading or water aeration.

Innovation Solution

A modular photovoltaic panel support system comprising sealed plastic envelopes with built-in flotation capabilities, featuring elastomer fixing profiles and aeration channels, allowing for easy assembly, cost-effective manufacturing, and efficient cooling and oxygenation of the water surface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If traditional metal frame support structures with plastic floats are used, then photovoltaic panels can be supported on water, but the structure becomes complex and requires significant logistics for manufacturing, transportation, and assembly

Engineering Contradiction:
Improvepanel support stabilityVSAvoidsupport structure complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines the support function and flotation function into a single integrated plastic casing structure. The casing itself provides both mechanical support for the photovoltaic panel and buoyancy through its sealed hollow design, eliminating the need for separate metal frames and plastic floats that were required in traditional solutions.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The plastic casing serves multiple functions simultaneously: it acts as the structural support framework, provides flotation through its sealed hollow design, offers protection against water ingress, and enables modular assembly through standardized connection elements. This multi-functionality reduces overall system complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Reliability

If framed or unframed panels are fixed using traditional methods, then panels can be secured, but the fixation process becomes costly and complex

Engineering Contradiction:
Improvepanel fixation securityVSAvoidfixation cost and complexity
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The retaining means are integrated directly into the plastic casing structure rather than being separate components. The casing includes built-in features such as recesses, protrusions, or channels that directly retain the photovoltaic panel, eliminating the need for additional fixation hardware and simplifying the overall manufacturing process.

Inventive Principle:
Principle #5Merging (Combining)

3Productivity

If panels are installed in rows without intermediate spacing, then space is maximized, but panels cast shadows on successive rows reducing efficiency

Engineering Contradiction:
Improvespace utilizationVSAvoidpanel efficiency
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent introduces intermediate rows of connection elements that physically separate adjacent rows of support devices. This segmentation creates maintenance corridors and prevents shadow casting between rows while maintaining efficient space utilization through the modular nature of the connection elements.

Inventive Principle:
Principle #1Segmentation

4Ease of manufacture

If modular plastic casing devices are used, then manufacturing and transportation become easier, but the devices must withstand swell conditions and prevent water projection onto panels

Engineering Contradiction:
Improvemanufacturing and transport easeVSAvoidweather resistance
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The patent uses sealed plastic casings that function as flexible yet durable shells resistant to water ingress. The plastic material provides both the necessary flexibility for modular assembly and the durability to withstand swell conditions, while the sealed design prevents water projection onto the photovoltaic panels.

Inventive Principle:
Principle #30Flexible shells and thin films
