Notched MC Cable Assembly Tape for Easy Manual Tearing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing adhesive tapes on armored and Metal-Clad cables are difficult to tear during installation and removal due to their high strength, necessitating tool-assisted tearing which complicates the process.
Innovation Solution
A notched assembly tape is used that is wrapped around the conductors, featuring non-adhesive inner and outer surfaces, with notches along the edges to facilitate manual tearing without compromising the tape's tensile strength.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a high-strength adhesive assembly tape is used to wrap the conductors, then the cable assembly maintains strong structural integrity and keeping cables together, but the tape becomes difficult to tear manually during installation and removal
Solution Approach 1:
The assembly tape incorporates notches or perforations that segment the tape structure, creating predetermined weak points that allow manual tearing while the rest of the tape maintains its high-strength adhesive properties for securing conductors
Solution Approach 2:
The tape has different properties at different locations: the majority of the tape surface maintains high-strength adhesive characteristics for secure bonding, while specific localized regions contain notches or reduced-adhesive zones that facilitate easy manual tearing
