Solution Overview

Problem

The existing methods for electrically coupling solar shingles are unsightly and interfere with the installation and water sealing of shingles, as they require exposed wires and cables, which deter homeowners and complicate the stacking of shingles on roofs.

Innovation Solution

A connector assembly that electrically couples solar shingles by engaging conductive members in recesses of the supporting sections, with a protective cover encasing the contact to prevent exposure and ensure seamless installation and water sealing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If wires and cables are used to electrically couple solar shingles, then electrical coupling is achieved, but the wires and cables become exposed above the shingles which is unsightly and interferes with shingle stacking

Engineering Contradiction:
Improveelectrical couplingVSAvoidshingle stacking and water sealing
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent extracts the electrical coupling function from the visible exterior by placing contacts and conductive members inside recesses of the shingles. The contacts are received within recesses that extend from upper to lower surfaces, hiding the electrical coupling components beneath the shingle surface while maintaining electrical connectivity between adjacent shingles.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent implements nesting by placing contacts within recesses of the shingles. The contacts are nested inside the recesses rather than protruding outward, allowing the shingles to be stacked or staggered without interference from exposed wiring components while maintaining electrical coupling functionality.

Inventive Principle:
Principle #7Nested doll (Nesting)

2Reliability

If wires and cables are used for electrical coupling, then electrical connection is established, but the exposed wires prevent proper shingle overlap for water sealing

Engineering Contradiction:
Improveelectrical connectionVSAvoidwater seepage
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The electrical connection components (contacts and conductive members) are extracted from the exterior surface and placed within recesses of the shingles. This extraction allows shingles to overlap properly for water sealing without exposed wires interfering with the waterproofing function.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent moves the electrical coupling components from a two-dimensional surface arrangement to a three-dimensional configuration utilizing the depth of recesses. Contacts are positioned within recesses that extend through the shingle thickness, allowing electrical connection without occupying surface space that would interfere with water sealing overlap.

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

3Ease of operation

If contacts are placed in recesses of supporting sections, then aesthetic appeal and installation ease are improved, but protective measures are needed to ensure reliable electrical contact

Engineering Contradiction:
Improveinstallation ease and aestheticsVSAvoidelectrical contact reliability
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent applies beforehand cushioning by providing a protective cover that receives the contact within the recess. The protective cover prevents damage to the contact and ensures reliable electrical connection by protecting the contact components from environmental factors and installation damage before they are exposed to service conditions.

Inventive Principle:
Principle #11Beforehand cushioning (Prior cushioning)

Solution Approach 2:

The protective cover serves multiple functions: it protects the contact from damage, ensures reliable electrical connection, and maintains the aesthetic appearance by concealing the electrical components. The recess structure itself provides both mechanical support and protective enclosure for the contact.

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

AI summary

A connector assembly (100) for electrically coupling solar shingles (102, 104) is provided. The solar shingles (102, 104) include photovoltaic sections (106) that convert light into electricity and supporting sections (108) having upper surfaces to which additional solar shingles are mounted. The connector assembly (100) includes a contact (300) and a protective cover (308). The contact (300) electrically couples the photovoltaic sections (106) of adjacent solar shingles (102, 104) by engaging conductive members (302, 304) disposed in recesses (114, 116) of the supporting sections (108) of the solar shingles (102, 104). The protective cover (308) is disposed in the recesses (114, 116) of the solar shingles (102, 104). The protective cover (308) encloses the contact (300) between the protective cover (308) and the conductive members (302, 304).
