Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable management systems for photovoltaic and similar systems are inefficient in routing cables, leading to interference and potential de-rating issues, and often require complex installations.
Innovation Solution
A cable management system comprising snap-together cable-retaining spacer blocks and brackets that allow for easy assembly without tools, featuring cylindrical passages and semi-cylindrical channels to maintain appropriate spacing and support cables, which can be suspended from support cables and mounted on structures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional cable management systems are used, then cable routing is possible, but cable interference occurs and de-rating is required
Solution Approach 1:
The cable management system divides cables into separate modular units (cable trays, cable ladders, cable ducts) that can be independently configured. Each module handles specific cables, preventing interference between adjacent cables while maintaining organized routing throughout the system.
Solution Approach 2:
The system provides different spacing and configuration options for different cable types and locations. Critical cables receive greater spacing and protection in high-interference zones, while less sensitive cables use standard configurations, optimizing performance where needed without unnecessary complexity elsewhere.
2Ease of operation
If complex cable management systems are used, then cable organization is improved, but installation difficulty increases
Solution Approach 1:
The cable management system is divided into standardized modular components (trays, ladders, ducts, supports) that can be independently installed and configured. This segmentation allows installers to work with simple, repeatable units rather than complex integrated systems, reducing installation difficulty while maintaining excellent cable organization capabilities.
Solution Approach 2:
The modular components are designed with universal mounting interfaces and configuration options that adapt to various cable types and routing requirements. A single basic module can serve multiple functions through different arrangements, eliminating the need for specialized components for each situation and simplifying the overall installation process.
3Reliability
If adequate cable spacing is provided to prevent interference, then cable performance is maintained, but space efficiency decreases
Solution Approach 1:
The system utilizes three-dimensional space efficiently by arranging cables in vertical and horizontal planes using stacked trays, ladder structures, and suspended ducts. Adequate spacing is maintained between cables through vertical stacking and lateral separation, allowing high cable density without compromising performance by exploiting multiple spatial dimensions rather than only horizontal expansion.
Solution Approach 2:
Smaller cable trays and ducts are nested within or alongside larger structural supports and routing channels. This nesting approach allows multiple cable groups with appropriate spacing to be consolidated into compact arrangements, maintaining performance requirements while maximizing space utilization through hierarchical organization.

AI summary
A cable management system includes a cable-retaining spacer block (110) defining a plurality of cylindrical passages (118) arranged to define a rectangular array. Each cylindrical passage is configured to receive a transmission cable (T). Brackets (120) are configured to support ends of the cable-retaining spacer block and enable suspension from a support cable (S). Another cable management system (300) includes a center base (310), first and second intermediate wings (320) configured to operably couple to the center base to define a first plurality of cylindrical passages (328) configured to retain transmission cables therein, and first and second outer wings (330) configured to operably couple to the first and second intermediate wings to define a second plurality of cylindrical passages (340) configured to retain transmission cables therein. These cable management systems enable snap-together engagement without the use of tools, thus facilitating assembly.
