Snap-Lock Cable Conduit for Tool-Free Rooftop Cable Protection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cable management systems for outdoor facilities, such as solar panel applications, face challenges with protection against environmental hazards, ease of access for maintenance, and tool-free assembly, as they often require screws that can damage cables and are not waterproof or efficient in managing cable bends.
Innovation Solution
A cable protector system featuring a conduit with removably coupled top and bottom channels using cam surfaces for tool-free assembly and disassembly, an adhesive base for secure mounting, and aerodynamic design to reduce wind resistance, allowing easy access and protection against physical and environmental damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If screws are used to secure the conduit to a base, then the conduit is firmly fixed and protected, but the cables can be damaged by the screws and the assembly requires tools
Solution Approach 1:
The conduit is divided into separate sections that can be assembled without screws. The engaging edges feature interlocking mechanisms with cam surfaces that allow tool-free assembly while maintaining structural integrity and protecting cables from damage.
Solution Approach 2:
The screw-based mechanical fastening system is replaced with a cam-based latching mechanism. The cam surfaces convert linear motion into rotational locking action, providing secure fixation without requiring screws or tools that could damage the cables.
2Ease of operation
If all top cable layers and separating sheets are removed to access bottom layer cables, then complete access is achieved, but the separating sheets and lid can be lost or damaged and the process is extremely inconvenient
Solution Approach 1:
The conduit lid is designed to be removably coupled rather than permanently fixed. This dynamic design allows the lid to be easily removed for cable access and then securely reattached, preventing loss or damage while maintaining convenient access to all cables including the bottom layer.
Solution Approach 2:
The removable lid serves multiple functions: it provides protective coverage when installed, allows complete access when removed, and can be securely reattached to maintain system integrity. This multi-functional design eliminates the need for separate retaining mechanisms.
3Adaptability or versatility
If a complicated apparatus with defined spaces for each cable is used, then organization is achieved, but the system requires matching cable count to slot count, increases manufacturing costs, and needs numerous screws for assembly
Solution Approach 1:
The conduit provides a universal organizing structure where cables can be arranged flexibly without requiring a predetermined number of slots. The engaging edges and cam-based latching mechanism work regardless of cable quantity or type, eliminating the need to match cable count to slot count while maintaining organization.
Solution Approach 2:
The conduit is segmented into modular sections with standardized engaging edges. This segmentation allows flexible configuration and easy expansion without requiring a complete redesign or matching of specific cable counts to slot configurations, reducing manufacturing complexity.
4Strength
If the conduit is secured with numerous screws, then firm fixation is achieved, but the assembly method is not suitable for cold and snowy rooftops and requires tools
Solution Approach 1:
The screw-based fastening system is replaced with a cam-based latching mechanism that requires no tools for assembly. The cam surfaces enable tool-free engagement and locking, making the installation process suitable for cold and snowy rooftop conditions where carrying and using tools would be cumbersome and dangerous.
Solution Approach 2:
The cam-based latching mechanism is designed to be self-assembling without requiring external tools or complex procedures. The engaging edges automatically lock together through the cam action, enabling installers to work efficiently in harsh weather conditions without tool handling.
5Strength
If the conduit relies on a screw penetrating the trough to secure it, then fixation is achieved, but the enclosure is not waterproof
Solution Approach 1:
The conduit is designed as separate engaging sections with interlocking edges rather than a single screw-penetrated structure. This segmentation allows for continuous sealing along the joints without compromising structural strength, achieving both secure fixation and waterproofing.
Solution Approach 2:
The screw-penetration fixation method is replaced with a cam-based latching system that maintains enclosure integrity. The interlocking engaging edges with cam surfaces provide secure fixation without penetrating the trough, preserving waterproofing while achieving strong securing.

AI summary
A cable protector including a conduit having a top channel having at least one engaging edge and a bottom channel having at least one engaging edge adapted to be removably coupled to the engaging edge of the top channel. The pair of removably coupled engaging edges includes an outer portion having a profile including a projection extending from a step to a tip and an inner portion having a profile including a locking step. When urged against the inner portion, the outer portion is slidingly coupled to the inner portion until the step becomes locked in the locking step to form a cavity within the conduit to accommodate the cables. When pulled from the inner portion, the outer portion is slidingly decoupled from the inner portion after the step becomes dislodged from the locking step to provide access to cables disposed within the cavity.
