Engineering Contradictions & Design Principles
Engineering 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
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.
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.
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
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.
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.
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
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.
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.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The apparatus enables efficient varnish removal from copper wires during conveyance, improving safety and efficiency by allowing precise control over scraping depth and collection of varnish scraps, preventing accumulation and ensuring a clean operation.
Implementation Method 1
The bottom plate is mounted on an assembly line such that the linear motor carries along the bottom plate to move linearly
Implementation Method 2
The first motor propels the screw rod to rotate through the transmission of the synchronous belt such that the lead screw nut on the screw rod carries along the moving platform to reciprocate
Implementation Method 3
The second motor propels the two-way screw rod to rotate, thus making the upper blade holder and the lower blade holder move in the same direction or opposite directions
Implementation Method 4
The apparatus enables efficient varnish removal from copper wires during conveyance, improving safety and efficiency by allowing precise control over scraping depth and collection of varnish scraps

AI summary
A copper wire varnish stripping apparatus, comprising a bottom plate II (61), wherein a bottom surface of the bottom plate II is provided thereon with a linear motor (112), a top surface of the bottom plate II is provided thereon with a scraper mechanism (4000), and two sides of the scraper mechanism are respectively provided with a pressing mechanism (5000). By means of mounting the linear motor on the bottom plate II, the bottom plate II may be mounted on an assembly line such that the linear motor carries along the bottom plate II to move linearly. The bottom plate II will be provided thereon with a copper wire that has been conveyed over. The two ends of a section of the copper wire are tightly pressed by the pressing mechanisms, and the copper wire has been conveyed over is scraped by the scraper mechanism arranged between the pressing mechanisms. The present varnish stripping apparatus may directly perform a varnish scraping operation on copper wire that is being conveyed, thus saving time and providing a good scraping effect. The present varnish stripping apparatus further collects the varnish coating such that the apparatus is tidy, has good safety, has complete overall functions, and has strong practicability.
