Dual-Treating Laundry Drawer Rail for Vibration-Limited Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry apparatuses with auxiliary devices face challenges in design and manufacturing due to limited space and vibration issues, leading to reduced productivity and increased noise, especially in front-loading models with low installation openings, making it difficult to load and unload laundry efficiently.
Innovation Solution
A laundry apparatus with a dual treating system, including a first and second treating part, where the second treating part is installed in a drawer with a rail unit to limit movement and guide outward movement, enhancing productivity and reducing vibration and noise by allowing efficient inner configuration in a narrow space.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an auxiliary laundry device is installed in a stand below the main laundry device, then the user convenience for loading and unloading laundry is improved, but the device complexity and manufacturing difficulty increase due to limited space and multiple components
Solution Approach 1:
The patent combines the auxiliary laundry device with the stand structure by integrating the drawer into the stand's rail unit framework. The rail unit serves dual purposes: supporting the stand structure and guiding the drawer movement, thereby merging structural support and operational guidance functions into a single integrated component that reduces overall device complexity
Solution Approach 2:
The rail unit is designed to perform multiple functions simultaneously: it provides structural support for the stand, guides the drawer's outward movement, and limits vertical and horizontal vibrations. This multi-functionality reduces the number of separate components needed, simplifying manufacturing while maintaining user convenience
2Volume of moving object
If the auxiliary laundry device is installed in a narrow space within the stand, then the profile and compactness of the laundry apparatus are improved, but the manufacturing precision and installation difficulty increase due to space constraints
Solution Approach 1:
The drawer is designed with movable capability within the constrained space of the stand. The rail unit enables the drawer to move outward smoothly while maintaining compact integration when retracted, allowing the system to adapt between compact storage and functional operation states without requiring excessive precision in fixed positioning
Solution Approach 2:
The auxiliary laundry device is segmented into the drawer and the stand as separate but integrated components. The drawer can be manufactured independently and then installed into the stand's rail unit, allowing for modular manufacturing that reduces the overall manufacturing precision requirements compared to a fully integrated monolithic structure
3Ease of operation
If the drawer is allowed to move outward freely, then the ease of access to the auxiliary laundry device is improved, but the vibration and noise increase due to uncontrolled movement
Solution Approach 1:
The rail unit is designed with vibration-limiting features that prevent excessive movement before it can generate harmful vibrations and noise. The structure inherently restricts vertical and horizontal movements through its geometric constraints and friction characteristics, cushioning against unwanted motion while allowing necessary drawer extraction

AI summary
A laundry apparatus including a cabinet; a first space provided in the cabinet, in which a first treating part provided to treat laundry is installed; a second space provided in the cabinet, in which a second treating part provided to treat laundry is installed; a drawer movably provided in the second space, in which the second treating part is installed; and a rail unit configured to limit vertical and horizontal movement of the drawer with respect to the second space and to guide the outward movement of the drawer. Therefore, laundry may be treated by using the first and second treating parts and vibration and noise generated in the second treating part may be reduced.
