Solution Overview

Problem

Existing mounting solutions for solar panels on roofs, particularly those with insulation, are expensive and not suitable for all applications, and often fail to provide adequate support for heavy structures due to reliance on threaded bolts or nuts.

Innovation Solution

A cost-effective attachment member with a massive connection member and lower attachment elements, such as tapered metal rods, that can be securely screwed into underlying construction elements like rafters or concrete decks, providing a stable and torsionally rigid anchoring system.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Strength

If threaded bolts or nuts are used to attach mounting brackets to underlying structures, then the attachment can be secured, but the system may not be sufficient to support heavy structures like solar panels adequately

Engineering Contradiction:
Improvesupport capacityVSAvoidadequacy for heavy structures
Core Design Contradiction:
StrengthVSReliability

Solution Approach 1:

The attachment member is divided into distinct functional segments: an upper bracket portion for mounting solar panels and a lower anchor portion for securing to the underlying structure. This segmentation allows each part to be optimized for its specific function, with the lower portion designed specifically for high-strength anchoring

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The attachment member combines different material properties within a single integrated component. The upper bracket portion can be made from materials suitable for structural support, while the lower anchor portion incorporates features (such as expanded metal or specialized geometry) optimized for anchoring strength in concrete or masonry, creating a composite structure that exceeds the capabilities of simple threaded bolts

Inventive Principle:
Principle #40Composite materials

2Ease of manufacture

If existing mounting brackets are used, then solar panels can be mounted, but the production costs are high and the installation process is complex

Engineering Contradiction:
Improveproduction costVSAvoidmounting system complexity
Core Design Contradiction:
Ease of manufactureVSDevice complexity

Solution Approach 1:

The invention merges multiple components into a single integrated attachment member. Instead of requiring separate brackets, anchors, bolts, and nuts, the design combines the mounting bracket and anchor into one piece that can be installed as a single unit, reducing both manufacturing steps and installation complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The lower anchor portion is designed to be self-installing into the underlying structure. The expansion mechanism or anchor geometry allows the lower portion to secure itself into concrete or masonry without requiring additional fasteners, threading operations, or complex assembly steps, making the product install-ready and reducing labor costs

Inventive Principle:
Principle #25Self-service

3Ease of operation

If multiple separate components are used for mounting, then attachment can be achieved, but the installation process becomes time-consuming and complicated

Engineering Contradiction:
Improveinstallation easeVSAvoidinstallation time
Core Design Contradiction:
Ease of operationVSLoss of time

Solution Approach 1:

By combining the bracket and anchor into a single pre-assembled unit, the invention eliminates the need for on-site assembly of multiple components. The integrated design allows installers to simply position and secure one component rather than coordinating multiple parts, significantly reducing installation time and complexity

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The attachment member is pre-assembled and pre-configured during manufacturing. The upper bracket and lower anchor are connected before delivery to the installation site, with all necessary alignment features and connection points already in place. This preliminary action transfers complexity from the installation phase to the manufacturing phase, where it can be more efficiently resolved

Inventive Principle:
Principle #10Preliminary action
