Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the driving mechanism is arranged on the axis of rotation of the moisture absorption disk, then the moisture absorption disk can be driven to rotate, but the structural size along the axis of rotation increases, resulting in increased height or thickness of the washer-dryer machine
Solution Approach 1:
The patent moves the driving mechanism from the axial dimension (center of the disk) to the radial dimension (outer peripheral edge), changing the spatial arrangement from central to peripheral. This dimensional shift allows the drive system to be positioned where it does not increase the axial height of the machine, while still effectively driving the moisture absorption disk through belt or gear transmission.
2Device complexity
If the connecting position between the moisture absorption disk and the driving mechanism is disposed at the center of the moisture absorption disk, then the driving mechanism can be compactly arranged, but the structure at the central area hinders the uniform passage of airflow through the disk
Solution Approach 1:
The patent extracts the driving mechanism from the central area of the moisture absorption disk and relocates it to the outer peripheral edge. This removal of the driving structure from the airflow path eliminates the obstruction caused by central connecting components, allowing air to flow uniformly through the entire surface of the disk without being blocked by belts, gears, or connecting rods at the center.
3Length of stationary object
If the driving mechanism is positioned at the outer peripheral edge of the moisture absorption disk, then the axial size of the assembly is reduced and airflow can pass uniformly, but the transmission distance for power delivery increases
Solution Approach 1:
The patent introduces a belt or gear as an intermediary transmission element that bridges the power source and the moisture absorption disk at the outer peripheral edge. This intermediary mechanism efficiently transmits power over the increased radial distance through the belt or gear system, which is designed with appropriate tension and engagement to minimize power loss while enabling the peripheral driving arrangement that reduces axial height and improves airflow.

AI summary
A drying module includes a moisture absorption and removal assembly. The moisture absorption and removal assembly includes a moisture absorption rotary wheel component, a rotary wheel shell, and a rotary wheel driving mechanism for driving the moisture absorption rotary wheel component to rotate. The moisture absorption rotary wheel component is rotatably arranged inside the rotary wheel shell and includes an outer peripheral shell member. A power input member configured to introduce power from the rotary wheel driving mechanism for rotating the moisture absorption rotary wheel component is arranged at an outer peripheral edge of the outer peripheral shell member. The power input member is driven by the rotary wheel driving mechanism at an outer peripheral edge of the power input member.
