Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washer-dryer machines with moisture absorption disks driven by a central mechanism increase structural size, hinder airflow, and reduce moisture absorption efficiency due to airflow non-uniformity.
Innovation Solution
A moisture absorption and removal assembly with a rotary wheel component driven at its outer peripheral edge, utilizing space efficiently and allowing uniform airflow passage, reducing the axial size and enhancing moisture absorption efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the driving mechanism is arranged at the center of the moisture absorption disk, then the power transmission is direct and simple, but the axial size increases and the structure becomes bulky
Solution Approach 1:
The patent moves the driving mechanism from the axial direction (center of the disk) to the radial direction (outer peripheral edge). This dimensional shift allows the power transmission to occur at the periphery rather than through the center, reducing the axial projection and making the structure flatter while maintaining effective power transmission to the rotating component.
2Shape
If the driving mechanism is arranged at the center of the moisture absorption disk, then the structure is compact in radial direction, but the transmission structure hinders uniform airflow passage
Solution Approach 1:
The patent extracts the driving mechanism from the central region of the moisture absorption disk and relocates it to the outer peripheral edge. This removal of the transmission structure from the center creates an unobstructed central passage, allowing airflow to pass through the disk uniformly without being blocked by gears, belts, or other transmission components that would be present in a center-driven configuration.
3Power
If the driving mechanism is arranged at the center, then the power input is direct, but the airflow cannot uniformly reach the moisture absorption disk surface
Solution Approach 1:
The patent relocates the power input from the axial dimension (center drive) to the radial dimension (peripheral drive). This allows the power transmission to occur at the outer edge where it does not interfere with the central airflow passage, enabling both effective power transmission and uniform airflow distribution across the moisture absorption disk surface.
Applied Scientific Principles
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 results in a flatter washer-dryer machine design with improved airflow distribution and continuous moisture absorption capability, enhancing drying efficiency while minimizing structural height and thickness.
Implementation Method 1
a moisture absorption disk formed by a moisture absorption material is rotatably arranged in a shell. An inner cavity of the shell is divided into a moisture absorption area and a moisture removal area. The moisture absorption disk absorbs moisture when rotating to the moisture absorption area and removes the moisture when rotating to the moisture removal area

AI summary
A drying module and a laundry dryer of a washing-drying integrated machine. The drying module (D) comprises a moisture absorption and removal assembly (D1). The moisture absorption and removal assembly (D1) comprises a moisture absorption rotary wheel component (D11), a rotary wheel shell (D12), and a rotary wheel driving mechanism (D13) for driving the moisture absorption rotary wheel component (D11) to rotate. The moisture absorption rotary wheel component (D11) is rotatably arranged inside the rotary wheel shell (D12); the moisture absorption rotary wheel component (D11) comprises an outer peripheral shell member (D112), wherein a power input member (D114), which is used for introducing power for rotating the moisture absorption rotary wheel component (D11) from the rotary wheel driving mechanism (D13), is arranged at an outer peripheral edge of the outer peripheral shell member (D112), and the power input member (D114) is driven by means of the rotary wheel driving mechanism (D13) at the outer peripheral edge thereof. The drying module can contribute to the reduction of the overall height or thickness of the washing-drying integrated machine, such that no transmission structure which hinders an airflow from flowing therethrough is arranged at a central area of a wheel disk, which is also beneficial for guiding the airflow to pass through the wheel disk more uniformly.
