Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a condensing duct is used to condense moisture in the air during drying, then moisture condensation is achieved, but the tub and drum capacities are reduced and the machine size increases
Solution Approach 1:
The condensing plate is integrated directly onto the inner wall of the tub, merging the condensation function with the existing tub structure. This eliminates the need for a separate condensing duct, thereby maintaining tub and drum capacities while achieving moisture condensation during the drying process
Solution Approach 2:
The condensing plate is positioned within the existing tub structure, nesting the condensation function inside the available space of the tub interior. This allows the condensation system to be embedded without increasing the overall machine size or reducing the functional capacity of the tub and drum

3Reliability
If a condensing duct is used to condense moisture in the air during drying, then moisture condensation is achieved, but flow resistance increases leading to inefficient drying
Solution Approach 1:
The invention extracts the condensation function from the separate condensing duct system and relocates it directly to the tub interior wall. This removes the unnecessary flow path through a dedicated duct, thereby reducing flow resistance and improving air circulation and drying efficiency while maintaining effective moisture condensation
Solution Approach 2:
Instead of using a separate duct to transport air for condensation, the invention inverts the approach by placing the condensing surface directly in the path of the drying air within the tub. This direct contact approach reduces flow resistance and improves drying efficiency while maintaining effective moisture condensation
