Solution Overview

Problem

Conventional solar tables for photovoltaic systems are not suitable for large spans due to their weight and design, leading to high manufacturing and assembly costs, limited usable area, and inefficient use of space underneath.

Innovation Solution

A solar table system with asymmetrical support and module support units, featuring lightweight, one-piece main beams and module carriers with positive-locking connections, allowing for greater spans and easier assembly, and eliminating the need for screws or clamps.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If conventional C-profiles made of zinc-coated steel are used for supports, beams, and mounting brackets, then the structural strength is sufficient, but the weight becomes considerable making installation difficult and manufacturing costs high

Engineering Contradiction:
Improvestructural strengthVSAvoidweight of solar table components
Core Design Contradiction:
StrengthVSWeight of stationary object

Solution Approach 1:

The patent changes the material parameter from conventional zinc-coated steel to plastic-coated steel profiles, and modifies the cross-sectional geometry parameters of the profiles. This combination allows achieving the required structural strength with reduced wall thicknesses and overall weight, while maintaining durability through the protective coating

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs composite construction by combining steel profiles with plastic coating layers. The steel provides the structural strength and load-bearing capacity, while the plastic coating provides corrosion protection and reduces the overall density of the component, thereby reducing weight without compromising strength

Inventive Principle:
Principle #40Composite materials

2Stability of the object's composition

If supports are spaced close together to ensure structural stability, then the stability is improved, but the usable area underneath the solar table becomes very limited

Engineering Contradiction:
Improvestructural stabilityVSAvoidusable area underneath solar table
Core Design Contradiction:
Stability of the object's compositionVSArea of stationary object

Solution Approach 1:

The patent modifies the geometric parameters of the support profiles, using optimized cross-sectional shapes with increased moment of inertia. This allows the profiles to maintain structural stability and resistance to bending forces while being spaced further apart, thereby increasing the usable area underneath the solar table structure

Inventive Principle:
Principle #35Parameter changes

3Length of stationary object

If the wall thickness of profiles is increased to achieve large spans, then the structural integrity is maintained, but the manufacturing and assembly costs increase disproportionately

Engineering Contradiction:
Improvespan lengthVSAvoidmanufacturing and assembly cost
Core Design Contradiction:
Length of stationary objectVSEase of manufacture

Solution Approach 1:

The patent optimizes the wall thickness parameter by combining it with improved profile geometry and plastic coating protection. This allows achieving the required structural integrity for large spans with thinner, more economical walls, reducing material costs and improving ease of manufacture and assembly

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent divides the solar table structure into modular components (supports, beams, mounting brackets) that can be manufactured separately with optimized wall thicknesses and assembled on-site. This segmentation allows for more economical manufacturing of individual components while achieving the required span lengths through proper structural design and connection methods

Inventive Principle:
Principle #1Segmentation
