Solution Overview
Problem
Existing drying devices face challenges in rapidly raising the temperature of a medium for efficient drying while minimizing the risk of excessive heating, which can lead to medium deterioration.
Innovation Solution

Engineering Contradiction Analysis
1Speed
If the set temperature of the heating section is high, then the temperature of the medium rises rapidly, but the medium may be excessively heated and deteriorated
Solution Approach 1:
The heating section is divided into multiple heating mechanisms (first, second, third heating mechanisms) arranged in the transport direction. Each heating mechanism has different set temperatures and distances from the medium, allowing staged heating that rapidly raises temperature while preventing excessive heating through progressive temperature reduction downstream
Solution Approach 2:
Different heating mechanisms are assigned different local heating characteristics: the first heating mechanism operates at a higher set temperature with a smaller distance to the medium for rapid heating, while subsequent mechanisms operate at progressively lower temperatures with larger distances to maintain and complete drying without causing deterioration
2Device complexity
If a single heating mechanism is used, then the device structure is simple, but the temperature control precision is insufficient to prevent medium deterioration
Solution Approach 1:
The heating section is segmented into multiple independent heating mechanisms with different set temperatures and positions. This segmentation enables precise temperature control at different stages of the drying process, ensuring the medium is heated effectively without exceeding safe temperature thresholds that would cause deterioration
