FRP Crown Molding Cable Compartments for Safe Wiring and Lighting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing crown molding systems face challenges in safely routing and securing power and communications cables, particularly in preventing unsafe bends, providing secure hardware installation, and optimizing lighting efficacy, while adhering to electrical codes and facilitating the integration of advanced lighting and communication systems in buildings.
Innovation Solution
A crown molding system with segregated compartments for power and communications cables, incorporating a light reflector for improved lighting efficacy, and secure hardware installation methods that prevent unsafe bends and allow easy access for upgrades or changes, using Fiber Reinforced Polymer (FRP) for structural support and a light reflector assembly for redirecting light.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If electrical cables are routed through crown molding, then lighting can be provided, but cable damage from unsafe bends occurs
Solution Approach 1:
The crown molding is divided into multiple compartments, with separate channels for power cables and communications cables. This segmentation prevents cables from bending sharply against each other and provides dedicated protected pathways for each cable type, eliminating the harmful bending effect while maintaining lighting functionality.
Solution Approach 2:
A cable management system with bendspes and routing channels acts as an intermediary between the crown molding structure and the cables. This intermediary component guides cables through safe bending radii and prevents direct contact with sharp edges, thereby protecting cables from damage while enabling lighting installation.
2Ease of operation
If hardware is installed in crown molding, then electrical connections can be made, but installation complexity increases
Solution Approach 1:
Hardware mounting locations and cable access points are pre-configured within the crown molding structure during manufacturing. This preliminary action eliminates the need for complex field installations, as hardware can be directly mounted to pre-positioned attachment points and cables can be accessed through pre-routed channels, simplifying the overall installation process.
Solution Approach 2:
The crown molding structure incorporates universal mounting mechanisms that can accommodate various hardware types (electrical boxes, connectors, lighting fixtures) through standardized attachment points. This multi-functionality allows different electrical connections to be made using the same basic mounting system, reducing installation complexity despite the added capability.
3Reliability
If cable access is restricted for safety, then code compliance is achieved, but future upgrades become difficult
Solution Approach 1:
The cable management system features nested, removable components where cable access points are integrated within the crown molding but can be independently accessed. This nesting allows the overall structure to remain code-compliant and secure while providing controlled access points for cable management, future upgrades, and maintenance without compromising safety or requiring full disassembly.

AI summary
A crown molding assembly that enables safely incorporating electrical and communications cabling within the crown molding by providing segregated compartments for electrical and copper communications cabling, wherein the decorative face is formed of a composite of fiber reinforcing polymer (FRP) including a fiber-reinforced structure having an increased directionality of said reinforcing fibers causing the decorative face to fracture upon being pierced by a fastener in a manner that renders the damaged section of the decorative face unable to hold the fastener, protecting the electrical cables and any other equipment located behind the decorative face from damage, and enables the secure installation of hardware either concealed within the molding or securely and favorably positioned through the decorative face to view or sense a room, and enables additional cable capacity that is concealed within a light reflector to increase lighting efficacy and power and data delivery capacity.
