Rotatable Conduit Cap for Multi-Orientation Cable Sealing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing roof-mounted cable securing systems for lightning protection lack a reliable and adaptable mechanism to securely fasten cables in both vertical and horizontal orientations while maintaining a watertight seal.
Innovation Solution
A conduit cap system comprising a metal cast cap with a central threaded axial blind opening, an outer clamp member with angularly spaced shoulders and recesses, and a bolt for clamping the cable, allowing for secure cable retention in various orientations through a rotatable clamp mechanism.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a conventional cable securing system is used, then the cable can be fastened in one orientation, but the system cannot adapt to both vertical and horizontal orientations while maintaining a watertight seal
Solution Approach 1:
The clamp member is designed to be rotatable relative to the cap, allowing the cable securing system to dynamically adjust between vertical and horizontal orientations. The rotatable connection maintains the watertight seal throughout the rotation, enabling the system to adapt to different mounting orientations without compromising the seal integrity.
Solution Approach 2:
The conduit cap assembly is designed as a multi-functional unit that can secure cables in multiple orientations (vertical and horizontal) while maintaining a consistent watertight seal. The combination of the cap, clamp member, and rotatable connection creates a universal mounting solution that eliminates the need for separate vertical and horizontal mounting components.
2Adaptability or versatility
If a rotatable clamp mechanism is added to achieve multi-orientation capability, then the adaptability improves, but the device complexity increases
Solution Approach 1:
The rotatable connection is integrated as an inherent feature of the cap and clamp member assembly, merging the rotation mechanism with the existing structural components. This integration avoids adding separate, complex rotation devices and maintains simplicity while enabling multi-orientation capability.

AI summary
The conduit cap includes a cap, an outer clamp member, and a bolt. The cap defines a central first threaded axial blind opening and has a top and an interior cylindrical rim coaxial with the central threaded opening and has an outer clamp defining a transverse second threaded opening and has two outwardly projecting angularly spaced shoulders. The outer clamp member defines a third opening alignable with the transverse second opening and a pair of parallel recesses. The outer clamp member has two pairs of opposed wings. Each pair of wings at least defining a recess dimensioned to receive a shoulder. The bolt is insertable though the third opening and threadably engageable in the transverse opening to clamp the outer clamp member to the first clamp.
