Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional open-loop cutting and slitting methods are used, then the manufacturing process is simple, but the manufacturing precision of electrode plates deteriorates due to accumulated errors in tab and slitting positions
Solution Approach 1:
The patent implements closed-loop feedback control by using visual detection mechanisms to measure actual tab positions and slitting positions, then feeding this information back to deviation correcting mechanisms that adjust subsequent cutting and slitting operations. This feedback loop eliminates accumulated errors in traditional open-loop systems, achieving consistent electrode plate dimensions across multiple pieces without requiring overly complex equipment.
Solution Approach 2:
The patent replaces traditional mechanical measurement and adjustment methods with visual detection mechanisms (cameras or sensors) and automated deviation correcting mechanisms. This substitution of mechanical systems with optical/electronic systems enables precise, non-contact measurement and automated correction of positional deviations, improving manufacturing precision while keeping the overall system complexity manageable.
2Measurement precision
If manual measurement and adjustment methods are used, then the device complexity is low, but the measurement precision of tab and slitting positions deteriorates
Solution Approach 1:
The patent replaces manual measurement with automated visual detection mechanisms that use cameras or sensors to capture images of tab positions and slitting positions. This substitution provides objective, high-precision measurement without the subjectivity and limited accuracy of manual methods, while the automated image processing and deviation calculation keep the system complexity manageable.
Solution Approach 2:
The patent uses visual detection to create digital copies (images) of the physical electrode plate features (tabs and slitting lines). These digital copies are then processed to calculate deviations from standard positions, enabling precise measurement without direct physical contact. This copying approach maintains measurement precision while avoiding the complexity of elaborate mechanical measurement systems.
3Manufacturing precision
If closed-loop feedback control is implemented, then the manufacturing precision of electrode plates is improved, but the device complexity increases due to additional detection and correction mechanisms
Solution Approach 1:
The patent implements closed-loop feedback control where visual detection mechanisms measure actual positions of tabs and slitting lines, the control unit calculates deviations from standard positions, and deviation correcting mechanisms adjust subsequent operations based on this feedback. This feedback loop systematically eliminates accumulated errors, achieving consistent electrode plate dimensions while managing system complexity through automated control algorithms.
Solution Approach 2:
The system performs self-correction by automatically detecting positional deviations and adjusting subsequent cutting and slitting operations without external intervention. The deviation correcting mechanisms use the measured deviation information to self-adjust, eliminating the need for manual measurement and adjustment while maintaining high precision, thus managing complexity through automation rather than human operation.
4Stability of the object's composition
If deviation correcting mechanisms are used, then the consistency of insulating and active material areas is improved, but the ease of manufacture deteriorates due to additional adjustment steps
Solution Approach 1:
The deviation correcting mechanisms automatically adjust tab cutting and slitting positions based on measured deviations, eliminating the need for manual measurement and adjustment steps. The system performs self-correction, maintaining consistent insulating and active material areas without requiring operators to intervene, thus preserving ease of manufacture while achieving high composition stability.
Solution Approach 2:
The patent replaces manual measurement and adjustment operations with automated visual detection and deviation correction systems. This substitution eliminates the need for operators to physically measure and adjust each electrode plate, maintaining material area consistency through automated control while keeping the manufacturing process simple and easy to operate.
