Laundry Drawer Rail Structure for Vibration and Noise Reduction
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 efficiently load and unload laundry and maintain the devices effectively.
Innovation Solution
A laundry apparatus design featuring a cabinet with separate spaces for treating parts, a drawer for easy access, and a rail unit to limit movement, along with shock-absorbing and vibration-reducing components, such as the shock preventing part and rear lock, to enhance productivity and reduce noise and vibration.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If an auxiliary laundry device is installed in the stand of a front loading laundry apparatus, then the user convenience for loading and unloading laundry is improved, but the device complexity and manufacturing difficulty increase due to limited space
Solution Approach 1:
The auxiliary laundry device is nested within the stand structure of the front loading laundry apparatus. The stand is not merely a support but contains the auxiliary device with its treating part, drawer, and rail unit, effectively placing one functional system inside another to maximize space utilization while maintaining user convenience
Solution Approach 2:
The stand serves multiple functions: it provides structural support for the main laundry apparatus, offers additional storage or support functionality, and houses the auxiliary laundry device. This multi-functionality reduces the need for separate components and simplifies manufacturing
2Shape
If various components are installed in a relatively small space of the auxiliary laundry device, then the profile is maintained, but the manufacturing precision and design difficulty worsen
Solution Approach 1:
The auxiliary laundry device is divided into distinct functional segments: the treating part for laundry treatment, the drawer for removable access, and the rail unit for guided movement. This segmentation allows each component to be manufactured and assembled separately with standardized interfaces, reducing overall manufacturing complexity despite compact dimensions
Solution Approach 2:
The drawer is designed to be movable rather than fixed, allowing it to slide along the rail unit. This dynamic design enables flexible space utilization and easier maintenance access while maintaining a compact profile when closed, balancing structural requirements with operational needs
3Productivity
If the auxiliary laundry device is installed in the stand, then space utilization is improved, but vibration and noise increase
Solution Approach 1:
The shock preventing part is installed beforehand between the auxiliary laundry device and the stand structure to cushion and absorb vibrations generated during laundry treatment. This preventive measure reduces noise and vibration transmission to the main apparatus and surrounding structures before they can propagate

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.
