Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If press notching is used to cut the secondary battery electrode, then manufacturing cost is reduced, but manufacturing precision and reliability deteriorate due to inability to achieve precise and continuous cutting
Solution Approach 1:
A jig is introduced as an intermediary device between the press notching system and the secondary battery electrode. The jig includes a first plate that supports the electrode and a second plate with a laser passage that presses the electrode, creating a controlled environment for precise cutting while maintaining the simplicity of press notching manufacturing
Solution Approach 2:
The pressing device is segmented into two separate plates (first plate and second plate) with a gap between them, allowing the laser beam to pass through the laser passage in the second plate and reach the electrode for precise cutting while the plates provide structural support and positioning
2Reliability
If the laser beam path is not properly controlled, then device complexity is reduced, but reliability deteriorates due to interrupted laser irradiation
Solution Approach 1:
The jig acts as an intermediary structure that ensures continuous laser beam delivery to the electrode. The first plate supports the electrode while the second plate with the laser passage maintains proper positioning and alignment, preventing interruptions in laser irradiation without requiring complex control systems
Solution Approach 2:
The jig is designed to pre-position the secondary battery electrode on the first plate and maintain proper alignment before laser cutting begins. This preliminary positioning ensures the laser beam continuously irradiates the electrode throughout the cutting process without interruptions

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 jig improves the quality and reliability of laser notching by maintaining the electrode in a flat, unbent state and allowing for precise control over laser exposure, facilitating easy changes in notching patterns and optimal performance.
Implementation Method 1
