Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If hot air is used to dry the electrode active material, then the drying process can be performed, but it takes a long time to dry the electrode significantly deteriorating productivity
Solution Approach 1:
The patent replaces the conventional hot air drying method with direct contact heating using a heating roller. The heating roller directly contacts the electrode and transfers heat through thermal conduction, eliminating the need for hot air circulation and significantly reducing drying time while improving productivity
Solution Approach 2:
The heating roller acts as an intermediary between the heat source and the electrode. It directly contacts the electrode surface and transfers heat efficiently through thermal conduction, serving as a mediator that accelerates the drying process compared to indirect hot air heating
2Productivity
If the notching process and drying process are performed separately, then each process can be optimized, but work efficiency is significantly deteriorated
Solution Approach 1:
The patent merges the notching process and drying process into a single integrated operation. The heating roller serves dual functions: it performs the notching operation while simultaneously drying the electrode through direct thermal contact, thereby improving work efficiency without significantly increasing device complexity
