Clip-On Cable Joint Tool for Simple Support Tube Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing tools for extracting support tubes from electrical cable junctions are not ergonomic, complex to operate, environmentally harmful, and costly, failing to meet the needs of simplicity, sustainability, and cost-effectiveness.
Innovation Solution
A tool with a central gripping part and L-shaped arms that clip onto support tube lugs, allowing easy extraction with a 'clip and pull' action, made from recycled plastic and a single molded piece, minimizing manufacturing complexity and environmental impact.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If existing tools for extracting support tubes are used, then the support tube can be removed, but the tool is not ergonomic and complex to operate
Solution Approach 1:
The tool is divided into distinct functional segments: a gripping element with opening that clips onto the support tube lug, a lever arm extending from the gripping element, and a handle at the end of the lever arm. This segmentation allows each part to perform its specific function efficiently while keeping the overall structure simple and easy to operate.
Solution Approach 2:
The opening in the gripping element acts as an intermediary mechanism that connects the operator's manual force to the support tube lug. By clipping onto the lug through this opening, the tool creates a simple mechanical connection that translates pulling force directly to the support tube extraction without complex transmission mechanisms.
2Ease of manufacture
If existing tools for extracting support tubes are used, then the support tube can be removed, but the tool has high environmental impact and manufacturing cost
Solution Approach 1:
The tool combines multiple functions into a single integrated structure: the gripping element, lever arm, and handle are formed as one piece through injection molding. This merging eliminates the need for separate components, reducing manufacturing steps, material waste, and assembly operations, thereby lowering both cost and environmental impact.
Solution Approach 2:
The tool is designed to be made from recycled plastic materials, changing the material parameter from virgin plastic to post-consumer recycled content. This parameter change reduces environmental impact by diverting plastic waste from landfills while maintaining the structural integrity and functionality required for support tube extraction.
