Modular Fastener System for Safe Cable Installation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In mining environments, securing and removing cables from wire meshes using ladders poses safety risks due to the danger of ladder topples and visibility issues in dimly lit, dusty conditions.
Innovation Solution
A fastener system comprising a looped body with complementary connectors and an installation device featuring a rotatable cap and spring mechanism for easy handling and deployment of fasteners, allowing cables to be securely attached and detached without the need for ladders.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If ladders are used to secure cables to wire mesh, then cable installation can be performed, but safety risks increase due to ladder topples and visibility issues
Solution Approach 1:
The patent introduces an intermediary device (cable installation tool with magnetic attachment) that mediates between the worker and the cable fastening process. The tool attaches to the wire mesh without requiring the worker to climb ladders, thereby eliminating the safety hazard while maintaining cable installation capability
Solution Approach 2:
The patent replaces the mechanical ladder-based approach with a magnetic attachment system. The magnetic force substitutes for the mechanical support previously provided by the ladder, allowing the installation tool to be held securely against the wire mesh without physical contact from the worker
2Productivity
If ladders are used in dimly lit, dusty environments, then cable installation can proceed, but visibility of ladders decreases increasing danger
Solution Approach 1:
The installation tool serves as an intermediary that eliminates the need for ladders in difficult-to-see environments. By attaching magnetically to the wire mesh, it provides a stable platform for cable fastening without requiring the worker to position or see a ladder in dimly lit, dusty conditions
3Strength
If cable ties are used to secure cables, then cables can be fastened to mesh, but removal requires cutting with wire cutters increasing time and complexity
Solution Approach 1:
The fastening system is segmented into modular components with standardized connectors. Each fastener contains complementary male and female connectors that can be easily engaged and disengaged, allowing individual fasteners to be removed and reused without cutting or special tools
Solution Approach 2:
The connector design incorporates dynamic engagement and disengagement mechanisms. The complementary connectors can be quickly connected by pushing together and disconnected by pulling apart, providing a dynamic fastening system that is both strong when connected and easy to modify when needed
