Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Use of energy by moving object

If traditional solar roofing systems are used, then solar energy conversion is achieved, but installation complexity and time increase significantly

Engineering Contradiction:
Improvesolar energy conversionVSAvoidinstallation complexity
Core Design Contradiction:
Use of energy by moving objectVSDevice complexity

Solution Approach 1:

The solar roofing system is divided into individual shingle units, each containing photovoltaic cells integrated into traditional shingle structures. This segmentation allows for modular installation where each shingle is a self-contained functional unit, simplifying the overall installation process compared to large custom panel systems.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The solar shingles are designed to serve dual functions: they provide traditional roofing protection while simultaneously generating solar energy. The standardized design with universal connectors allows the same shingle type to be used across different roof configurations, eliminating the need for custom panel fabrication for each installation.

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

2Use of energy by moving object

If traditional solar roofing systems are used, then solar energy conversion is achieved, but installation time increases to several weeks

Engineering Contradiction:
Improvesolar energy conversionVSAvoidinstallation time
Core Design Contradiction:
Use of energy by moving objectVSLoss of time

Solution Approach 1:

The solar shingles are pre-manufactured with integrated photovoltaic cells, connectors, and roofing materials in standardized units. All necessary components are prepared in advance during factory production, allowing for rapid on-site assembly without the need for time-consuming custom panel fabrication and data collection processes.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

By segmenting the solar roofing system into individual pre-fabricated shingle units, the installation process becomes a matter of assembling standardized components rather than installing large custom panels. This segmentation enables parallel installation workflows and significantly reduces the overall installation timeline from weeks to days.

Inventive Principle:
Principle #1Segmentation

3Use of energy by moving object

If custom solar panels are used, then solar energy conversion is achieved, but manufacturing and design costs increase

Engineering Contradiction:
Improvesolar energy conversionVSAvoidmanufacturing cost
Core Design Contradiction:
Use of energy by moving objectVSEase of manufacture

Solution Approach 1:

The solar shingles utilize standardized designs that can be mass-produced using conventional manufacturing processes. The universal connectors and modular architecture allow the same basic shingle design to be used across different applications, enabling economies of scale in manufacturing and reducing per-unit costs compared to custom panel systems.

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

Solution Approach 2:

The invention merges traditional roofing materials with photovoltaic cells into a single integrated product. This combination eliminates the need for separate manufacturing processes for roofing materials and solar panels, streamlining production and reducing overall manufacturing costs through integrated fabrication processes.

Inventive Principle:
Principle #5Merging (Combining)

4Use of energy by moving object

If traditional solar roofing systems are used, then solar energy conversion is achieved, but the appearance does not conform to traditional roofing

Engineering Contradiction:
Improvesolar energy conversionVSAvoidroofing appearance
Core Design Contradiction:
Use of energy by moving objectVSShape

Solution Approach 1:

The solar shingles combine traditional roofing materials such as asphalt, fiberglass, and granules with photovoltaic cells to create a hybrid product that maintains the conventional appearance of traditional shingles. The photovoltaic cells are integrated beneath the outer layers, allowing the shingles to mimic the visual characteristics of conventional roofing while providing solar energy conversion functionality.

AI summary

A solar shingle having a substrate positioned beneath an upper material layer and at least one photovoltaic cell coupled to the substrate. A first terminal can be electrically coupled to the at least one photovoltaic cell and positioned adjacent to a first sidewall of the solar shingle, and a second terminal can be electrically coupled to the at least one photovoltaic cell and positioned adjacent to a second sidewall of the solar shingle. An upper surface of the upper material layer can have one or more recesses positioned between the first sidewall and the second sidewall and adjacent to the at least one photovoltaic cell. Further, the upper surface can have a variety of imparted surface characteristics, among other aesthetics and coloring, that can provide the solar shingle with outwardly appearance that is at least similar to traditional, non-solar shingles.
