Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a traditional puncher is used for notching electrode plates, then the notching process can be completed, but scraps generated during notching cannot be efficiently discharged
Solution Approach 1:
The invention extracts the scrap discharge function from the traditional puncher by introducing a separate scrap pusher mechanism. The pusher blade is specifically designed to enter the punch hole and push scraps outward, separating the cutting function (puncher) from the scrap removal function (pusher), thereby solving the inefficiency of scrap discharge in traditional notching processes
Solution Approach 2:
The pusher blade acts as an intermediary element between the puncher and the scrap. It enters the punch hole created by the puncher and mechanically pushes the scraps outward through the discharge hole, serving as a mediating component that enables efficient scrap removal without requiring external power sources or complex mechanisms
2Productivity
If a scrap pusher mechanism is added to discharge scraps, then scrap discharge efficiency improves, but the device complexity increases
Solution Approach 1:
The scrap pusher mechanism is designed to be self-actuating through the elastic deformation of the electrode plate during the notching process. As the electrode plate bends during punching, it automatically drives the pusher blade to move and push scraps outward, eliminating the need for external motors, sensors, or control systems. This self-service approach maintains high scrap discharge efficiency while minimizing device complexity
Solution Approach 2:
The pusher blade is designed with rotational freedom and elastic connection to the support body, allowing it to dynamically adapt its position and movement based on the punching process. The blade can rotate to follow the motion of the electrode plate and automatically return to its initial position after scrap discharge, providing dynamic scrap removal capability without complex mechanical linkages
3Productivity
If the pusher blade continuously contacts the scrap, then scrap discharge is effective, but wear on contact surfaces increases
Solution Approach 1:
The pusher blade engages in periodic contact with scraps rather than continuous contact. It pushes scraps outward during the punching phase, then returns to its initial position where the restoring force prepares it for the next cycle. This periodic action reduces cumulative wear on the blade and contact surfaces while maintaining effective scrap discharge during each punching operation
Solution Approach 2:
The pusher blade applies force to scraps only when necessary (during the punching phase), rather than maintaining constant contact. The restoring force ensures the blade returns to a non-contact position after scrap discharge, providing just enough action to achieve effective scrap removal while minimizing unnecessary contact and associated wear on surfaces
