Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing solar panel mounting systems are not leakproof, obstruct photovoltaic surfaces, and lack easy panel removal and customization, relying on the underlying structure for weatherproofing.

Innovation Solution

A panel support framework with angularly oriented beams and clamps secures solar panels in a vertically offset, non-overlapping arrangement, using seals to prevent leakage and allowing unimpeded water flow, with customizable sizing for various panel sizes and structures.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing solar panel mounting systems are used, then panels can be mounted on the roof, but the system is not leakproof and relies on the underlying structure for weatherproofing

Engineering Contradiction:

Improveleakproof capabilityVSAvoidindependence from underlying structure

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The mounting system is divided into separate functional components: the framework provides structural support while seals and flashing provide weatherproofing. This segmentation allows each component to be optimized independently, with the framework being customizable for different panel sizes and the sealing components providing reliable leak prevention.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Seals and flashing are introduced as intermediary elements between the solar panels and the roof structure. These intermediaries create a weatherproof barrier that prevents water infiltration while allowing the framework to remain independent from the underlying roof structure.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If existing mounting techniques are used, then panels can be secured to the structure, but connectors are externally visible and affect aesthetic appearance

Engineering Contradiction:

Improveaesthetic appearanceVSAvoidvisibility of connectors

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The connectors and fastening elements are extracted from visible positions and concealed within the framework structure or behind the solar panels. This allows the mounting system to function effectively while maintaining clean, aesthetic exterior surfaces without exposed hardware.

Inventive Principle:

Principle #2Taking out (Extraction)

3Ease of repair

If existing mounting systems are used, then panels can be installed on the structure, but individual panels cannot be easily removed for maintenance or replacement

Engineering Contradiction:

Improvepanel removabilityVSAvoidstructural integrity

Core Design Contradiction:

Ease of repairVSStability of the object's composition

Solution Approach 1:

The mounting system employs dynamic fastening mechanisms that provide secure attachment during normal operation but allow for easy release and removal when needed. This enables individual panels to be quickly removed for maintenance or replacement while maintaining structural integrity when panels are in place.

Inventive Principle:

Principle #15Dynamics

4Reliability

If existing mounting systems are used, then panels can be secured to the structure, but the system does not encourage rainwater shedding and may cause leakage

Engineering Contradiction:

Improveweather resistanceVSAvoidwater flow management

Core Design Contradiction:

ReliabilityVSEase of manufacture

Solution Approach 1:

The framework and panel arrangement create asymmetric positioning that promotes natural water shedding. Panels are positioned at angles and heights that encourage rainwater to flow off the structure efficiently, while seals and flashing are strategically placed to capture and redirect water away from vulnerable areas.

Inventive Principle:

Principle #4Asymmetry

5Ease of operation

If existing mounting systems are used, then panels can be mounted on the structure, but connectors are externally visible and do not provide clean external appearance

Engineering Contradiction:

Improveexternal appearanceVSAvoidconnector visibility

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

Inventive Principle:

Principle #2Taking out (Extraction)

AI summary

Systems for forming a pitched wall or roof section with solar panels on an underlying subframe include a panel support framework extending angularly upwardly over at least part of the subframe. In some embodiments, one or more clamps secures a first solar panel to the framework closer to the lower end than the upper end of the subframe and one or more other clamps secures a second solar panel to the framework at least partially adjacent and offset upwardly relative to the first solar panel between the first solar panel and upper end of the subframe.
