Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current conductor cleaning methods, such as using wire brushes, are ineffective in removing corrosion products and contaminants from aluminum strands of conductors, particularly failing to clean internal strands without unstranding the conductor, which can lead to compression connector failures due to increased resistance and thermal expansion/contraction issues.
Innovation Solution
A conductor cleaning system comprising a container with a cleaning solution and a vibrator-powered agitation mechanism, using a caustic solution of sodium hydroxide and sodium fluoride, that cleans both external and internal strands without unstranding the conductor, ensuring effective removal of contaminants and corrosion products while being safe for the conductor materials.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a wire brush is used to clean aluminum strands, then the cleaning process is simple and quick, but the cleaning effectiveness is poor and internal strands cannot be cleaned
Solution Approach 1:
The patent replaces the manual mechanical wire brush cleaning system with a chemical cleaning system using a caustic solution (sodium hydroxide and sodium fluoride) applied through a container that surrounds the conductor strands. The chemical solution effectively removes corrosion products and contaminants from both outer and internal strands without requiring manual unstranding, thus improving cleaning effectiveness while maintaining operational efficiency.
Solution Approach 2:
The patent introduces a caustic cleaning solution as an intermediary substance between the cleaner and the conductor strands. This chemical intermediary penetrates around all strands including internal ones, providing effective cleaning without direct mechanical contact, thereby solving the limitation of wire brushes that cannot reach internal strands.
2Reliability
If the conductor is unstranded to clean internal strands, then complete cleaning is achieved, but the risk of strand damage increases and the process becomes impractical
Solution Approach 1:
The patent replaces the mechanical unstranding process with a chemical cleaning system. The caustic solution is delivered through a container that allows the chemical to reach internal strands through the conductor structure without requiring physical separation of strands, thus achieving complete cleaning while eliminating the risks associated with manual unstranding.
Solution Approach 2:
The caustic cleaning solution serves as an intermediary that can penetrate through and around the conductor strands including internal ones. This chemical mediator provides access to all surfaces that need cleaning without requiring physical manipulation or separation of the strands, thereby maintaining strand integrity while achieving complete cleaning.
3Reliability
If a cleaning solution is used to clean all strands, then cleaning effectiveness improves, but the risk of chemical reaction with conductor materials may increase
Solution Approach 1:
The patent carefully selects and controls the chemical parameters of the cleaning solution, specifically using a caustic solution of sodium hydroxide and sodium fluoride at controlled concentrations. This parameter optimization allows the solution to effectively remove corrosion products and contaminants from aluminum and steel strands while maintaining safety by preventing harmful chemical reactions with the conductor materials.
Solution Approach 2:
The patent optimizes the chemical composition and concentration parameters of the cleaning solution to achieve effective cleaning without harmful reactions. The specific formulation of sodium hydroxide and sodium fluoride at controlled levels provides the right balance between cleaning power and material compatibility, ensuring effectiveness while preventing damage to the conductor strands.
