Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dryer is used to dry the active material layer, then the adhesive properties are improved, but the drying uniformity deteriorates due to air stream variations
Solution Approach 1:
A sensor measures the degree of dryness of the active material layer in real-time, and the processor adjusts the dryer operation based on this feedback to achieve uniform drying across the entire layer, compensating for air stream variations
Solution Approach 2:
The drying process is made dynamic by continuously adjusting the dryer operation based on real-time dryness measurements, transitioning from a static fixed-parameter drying process to an adaptive dynamic control process
2Productivity
If the active material layer is dried quickly, then the productivity is improved, but the drying uniformity deteriorates
Solution Approach 1:
The sensor provides real-time feedback on the degree of dryness, allowing the system to optimize drying speed while maintaining uniformity by adjusting parameters based on actual drying progress rather than relying on fixed time or temperature settings
Solution Approach 2:
The drying parameters (temperature, air flow) are dynamically changed based on the measured degree of dryness, allowing the system to accelerate drying when uniformity is achieved in certain regions while continuing to dry other regions
3Manufacturing precision
If additional drying is performed on all electrode plates, then the drying uniformity is improved, but the energy consumption increases
Solution Approach 1:
Instead of uniformly drying all electrode plates, the system applies additional drying only to specific plates or regions that require it, based on individual dryness measurements, thereby reducing unnecessary energy consumption while maintaining uniformity where needed
Solution Approach 2:
The system performs partial drying action only on electrode plates that require additional drying based on sensor feedback, rather than applying excessive drying to all plates, optimizing energy usage while achieving the required uniformity
