Combiner Cabinet Multi-Layer Layout for Shorter Wiring Paths
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In existing combiner cabinets, the long distances between electrical elements at the ends result in lengthy wiring requirements, making operations inconvenient for workers.
Innovation Solution
The combiner cabinet design arranges the positive and negative electrode portions in a first direction, with a compact layout using multiple shelves and integrated circuit breakers and fuses, reducing wiring distances and enhancing safety through dual circuit breakers for each electrode portion.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If electrical elements are arranged in one layer along the length direction of the combiner cabinet, then the cabinet can accommodate all necessary electrical elements, but the distances between electrical elements at two ends become long, resulting in lengthy wiring requirements and inconvenient operation
Solution Approach 1:
The patent transitions from a one-dimensional linear arrangement of electrical elements to a two-dimensional multi-layer arrangement. Electrical elements are distributed across multiple layers along the width direction of the cabinet, allowing workers to access elements on different layers simultaneously and reducing the maximum wiring distance between any two elements from the full length of the cabinet to much shorter distances within each layer or between adjacent layers.
Solution Approach 2:
The patent divides the single-layer arrangement into multiple separate layers, segmenting the electrical elements into different groups. This segmentation allows each layer to be independently accessed and wired, reducing the overall wiring complexity and distance. Each layer can be treated as a separate working zone, improving operational convenience.
2Adaptability or versatility
If a large number of electrical elements are arranged in one layer, then all electrical functions can be integrated, but the wiring distance increases and operation becomes inconvenient
Solution Approach 1:
The patent maintains full integration of electrical functions by distributing electrical elements across multiple layers rather than consolidating them in a single layer. This multi-layer arrangement preserves all necessary electrical connections and functions while organizing them in a three-dimensional space that improves accessibility and reduces wiring distances, thereby enhancing operational convenience without sacrificing functional integration.
