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 uneven drying occurs due to air stream circulation
Solution Approach 1:
The drying system is divided into multiple independent drying units (first drying unit and second drying unit) with separate air streams. This segmentation allows each unit to operate independently, preventing the uneven drying caused by a single circulated air stream while maintaining effective drying for adhesive properties.
Solution Approach 2:
Different regions of the electrode plate are exposed to different air stream conditions through the first and second drying units. The first drying unit provides drying from one side while the second drying unit provides drying from the other side, ensuring uniform drying quality across the entire electrode plate surface.
2Strength
If drying conditions are adjusted to improve adhesive properties, then bonding strength increases, but process complexity increases
Solution Approach 1:
The drying process is segmented into two independent drying units that can be controlled separately. This segmentation simplifies the control of drying conditions for each unit, making it easier to optimize adhesive properties without significantly increasing overall process complexity.
Solution Approach 2:
Two drying units are combined in the apparatus, where the first drying unit and second drying unit work together to dry both sides of the electrode plate simultaneously. This merging approach achieves uniform drying and improved adhesive properties while maintaining a relatively simple integrated structure.
3Manufacturing precision
If additional drying is performed to ensure uniform dryness, then quality is improved, but energy consumption increases
Solution Approach 1:
The first drying unit and second drying unit are combined to dry both sides of the electrode plate simultaneously. This merging of drying operations achieves uniform dryness across the entire electrode plate while minimizing energy consumption by eliminating the need for sequential drying or excessive additional drying.
