Solution Overview

Problem

Conventional copper wire varnish stripping apparatuses operate inefficiently, with cumbersome paint stripping processes, poor safety performance, and difficulty in clamping and fixing the copper wire, leading to complicated operations and ineffective varnish removal.

Innovation Solution

A copper wire varnish stripping apparatus with a moving platform and reciprocating blade holders that scrape the varnish coating from all sides of the wire, combined with a pressing mechanism and air suction system for efficient collection and secondary cleaning, ensuring precise control and tidy operation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If conventional stripping apparatuses perform varnish scraping only after cutting and extrusion forming, then the copper wire can be processed through all stages, but the varnish removal operation becomes inconvenient and complicated

Engineering Contradiction:
Improvevarnish scraping operation convenienceVSAvoidoverall processing efficiency
Core Design Contradiction:
Ease of operationVSProductivity

Solution Approach 1:

The patent applies preliminary action by performing varnish scraping at the beginning of the processing sequence, before cutting and extrusion forming, rather than after these operations. This reordering allows the varnish to be removed while the copper wire is still in a convenient state for handling, making the scraping operation easier and more efficient.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent employs a movable clamping device that can dynamically adjust its position along the copper wire. This dynamic positioning capability allows the clamping mechanism to adapt to different processing stages and maintain optimal gripping force, thereby improving operational convenience and processing efficiency.

Inventive Principle:
Principle #15Dynamics

2Reliability

If the copper wire is clamped and fixed for varnish scraping, then the scraping operation can be performed, but the clamping and fixing process becomes difficult and complicated

Engineering Contradiction:
Improvecopper wire fixation stabilityVSAvoidclamping and fixing mechanism complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The clamping and fixing mechanism is segmented into multiple independent components that can operate separately. This segmentation simplifies each individual clamping element while maintaining overall fixation stability, reducing the complexity of the entire system.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent uses a movable clamping device with dynamic adjustment capabilities, allowing the clamping force and position to be adjusted based on the specific requirements of the copper wire. This dynamic approach provides reliable fixation without requiring an overly complex fixed mechanism.

Inventive Principle:
Principle #15Dynamics

3Productivity

If varnish scraping is performed on conveyed copper wire, then time is saved and scraping effect is improved, but the varnish coating needs to be collected for safety and tidiness

Engineering Contradiction:
Improvevarnish scraping efficiencyVSAvoidvarnish coating accumulation
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the varnish coating from the copper wire surface using dedicated scraping blades, and then separates and collects this removed varnish in a collection device. This extraction and separation process prevents varnish accumulation and maintains a tidy working environment while preserving high scraping efficiency.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent converts the potentially harmful accumulation of varnish coating into a beneficial collected material by implementing a varnish collection device. The removed varnish, which could be considered waste or a safety hazard, is instead captured and managed systematically, turning a harmful factor into a controlled byproduct.

Inventive Principle:
Principle #22Blessing in disguise (Convert harm into benefit)
