Solution Overview
Problem
In closed cycle and air-condensation laundry dryers, high-speed cooling air discharged from the condenser causes vibration and noise by hitting the side panels, which existing designs fail to adequately mitigate.
Innovation Solution
A guide is positioned at the base of the dryer, connecting two openings at different perpendicular planes, forming a closed tube to direct the cooling air from the condenser discharge point to an outer opening, preventing it from spreading into the gap between the drum and the body, thereby reducing noise and vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the cooling air is discharged directly from the condenser without guidance, then the discharge structure is simple, but the cooling air hits the side panels causing high noise and vibration
Solution Approach 1:
A guide structure is introduced as an intermediary component between the condenser and the external environment. This guide channels the cooling air through a controlled path, preventing direct impact on the side panels and thereby reducing noise and vibration while managing the airflow effectively
Solution Approach 2:
The guide structure utilizes three-dimensional spatial arrangement to redirect cooling air. By creating a guided passage that extends in multiple dimensions, the airflow is directed toward the rear wall opening rather than horizontally toward the side panels, eliminating the harmful impact while maintaining structural efficiency
2Object-affected harmful factors
If the guide structure is added to channel cooling air, then noise and vibration are reduced, but the device complexity increases
Solution Approach 1:
The guide structure is integrated with the base unit and rear wall as a unified assembly. By merging these components into a cohesive structure, the noise-reduction function is achieved without proportionally increasing overall device complexity, as the guide utilizes existing structural elements
Solution Approach 2:
The guide structure employs thin-walled tubular formations that are lightweight yet effective at channeling airflow. These thin-film-like structures provide the necessary guidance function while minimizing material usage and structural complexity
3Temperature
If the cooling air flow rate is increased to improve cooling efficiency, then the cooling performance improves, but the noise and vibration from air impact on side panels increase
Solution Approach 1:
The guide structure serves as a mediator that allows high-flow cooling air to be transported efficiently from the condenser to the external environment. The guided passage maintains high airflow rates for effective cooling while preventing the air from directly impacting the side panels, thus eliminating noise and vibration even at high flow rates
Solution Approach 2:
The harmful impact effect is extracted and eliminated by redirecting the cooling air through the guide structure. The high-velocity airflow is taken out from its direct path toward the side panels and channeled through the guide to exit at the rear wall, preserving cooling efficiency while removing the noise-generating impact

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The solution effectively silences the dryer by ensuring all cooling air is discharged externally, reducing noise and vibration caused by the cooling air's impact on the side walls, resulting in a more silent operation.
