Engineering Contradictions & Design Principles
Engineering 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
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.
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.
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
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.
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.
3Adaptability or versatility
If multiple cable routing directions are needed, then array configuration flexibility improves, but traditional edge ports require complex cable management
Solution Approach 1:
The corner vertex positioning of connector ports enables cables to route in multiple diagonal directions from each corner, providing inherent multi-directional routing capability. This dimensional advantage allows flexible array configurations without requiring complex cable management systems.
