Solution Overview

Problem

Existing systems for fixing photovoltaic panels above the ground are bulky and require significant space for supporting structures and stays, limiting the use of land below for activities like agriculture due to the need for extensive posts and cables that cause structural stress and deformation.

Innovation Solution

A system utilizing a gantry structure with uprights and beams to support cables, allowing for efficient use of space by reducing the need for additional stays and enabling the use of land below for agricultural activities, with the gantries designed to accommodate photovoltaic panels and allow passage of agricultural machinery.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If photovoltaic panels are fixed to structures positioned on the ground close to the ground, then easy access for maintenance and replacement is achieved, but the ground surface is occupied and cannot be used for other purposes

Engineering Contradiction:
Improveaccessibility for maintenanceVSAvoidground surface availability
Core Design Contradiction:
Ease of operationVSArea of stationary object

Solution Approach 1:

The patent elevates photovoltaic panels from ground level to an aerial position using carrier cables suspended between supports, transitioning the installation from a two-dimensional ground plane to a three-dimensional spatial arrangement. This allows the ground surface to be freed for agricultural or other uses while panels remain accessible at elevated heights.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)

2Area of stationary object

If photovoltaic panels are fixed to structures at a determined distance from the ground, then ground surface is freed for other uses, but bulky structures with significant quantity of poles are required which limit space utilization

Engineering Contradiction:
Improveground surface availabilityVSAvoidquantity of supporting poles
Core Design Contradiction:
Area of stationary objectVSDevice complexity

Solution Approach 1:

The patent extracts the supporting function from traditional bulky pole structures and transfers it to tensioned carrier cables anchored at endpoints. This removes the need for intermediate vertical poles, freeing ground space while maintaining panel elevation and reducing structural complexity.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent replaces the mechanical pole-based support system with a cable-based suspension system. Instead of rigid vertical structures, flexible tensioned cables carry the photovoltaic panels, achieving the same support function with minimal ground interference.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Area of stationary object

If carrier cables and panels fixed on the carrier cables are used, then photovoltaic panels can be positioned above ground, but the assembly is relatively heavy causing significant force on posts which deforms them

Engineering Contradiction:
Improveground surface availabilityVSAvoidstructural integrity of supports
Core Design Contradiction:
Area of stationary objectVSStrength

Solution Approach 1:

The patent distributes the heavy load of panels and cables across multiple anchor points and uses tensioned cable systems that leverage mechanical advantage. The force is counterbalanced through proper anchoring and cable routing, preventing deformation of support structures.

Inventive Principle:
Principle #8Anti-weight (Counterweight)

4Stability of the object's composition

If additional cables in the form of guy wires are used to prevent deformation of posts, then structural stability is improved, but a lot of space is required which is a real disadvantage

Engineering Contradiction:
Improvestability of supporting postsVSAvoidspace utilization
Core Design Contradiction:
Stability of the object's compositionVSArea of stationary object

Solution Approach 1:

The patent removes the need for guy wires by eliminating intermediate vertical posts that required lateral bracing. The cable-supported system achieves stability through tension and proper anchoring without requiring additional stabilizing cables that would consume ground space.

Inventive Principle:
Principle #2Taking out (Extraction)
