Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If traditional wiring and connector positioning methods are used, then electrical connection between PV modules and inverters is achieved, but cable management becomes complex and installation difficulty increases

Engineering Contradiction:
Improveinstallation easeVSAvoidcable management complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The patent positions connector ports at the corner vertices of PV modules rather than on flat edges, utilizing the vertex dimension to enable diagonal cable routing. This dimensional change in connector placement allows cables to exit at angles that simplify routing through mounting structures and reduce cable management complexity.

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

Solution Approach 2:

The patent applies different connector port configurations to different locations on the module frame, specifically placing ports at corner vertices where they provide optimal routing angles. This localized optimization at critical connection points simplifies cable management without requiring changes to the entire module design.

Inventive Principle:
Principle #3Local quality

2Adaptability or versatility

If connector ports are positioned on module edges, then electrical connection is established, but cable routing flexibility is limited and access in limited spaces becomes difficult

Engineering Contradiction:
Improvecable routing flexibilityVSAvoidaccess in limited areas
Core Design Contradiction:
Adaptability or versatilityVSEase of operation

Solution Approach 1:

By moving connector ports from edge positions to corner vertex positions, the patent enables cables to exit at diagonal angles rather than being constrained to edge-parallel routing. This dimensional repositioning provides multiple routing directions and improves access in limited installation spaces.

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

Solution Approach 2:

The corner vertex positioning creates asymmetric routing opportunities that allow cables to exit at varied angles depending on the specific corner location. This asymmetric placement provides greater routing flexibility compared to symmetric edge positioning, adapting to different installation configurations.

Inventive Principle:
Principle #4Asymmetry

3Adaptability or versatility

If multiple cable routing directions are needed, then array configuration flexibility improves, but traditional edge ports require complex cable management

Engineering Contradiction:
