Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treatment apparatuses fail to effectively reduce horizontal vibration of the outer tub, leading to potential collisions with the casing and increased noise, especially in compact designs where space is maximized.
Innovation Solution
The implementation of horizontal vibration buffering devices that connect the outer tub to the casing using a combination of dampers and springs, providing attenuation forces to counteract the displacement caused by vibrations, thereby reducing the impact of horizontal vibrations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the gap between the casing and the outer tub is decreased to maximize the volume of the outer tub, then the volume of the outer tub is increased, but the horizontal vibration causes collision between the outer tub and the casing
Solution Approach 1:
The patent introduces a horizontal vibration buffering device as an intermediary element between the outer tub and the casing. This device includes a damper that provides attenuation force to reduce horizontal vibrations of the outer tub, preventing collision with the casing while allowing the outer tub to be positioned closer to the casing to maximize volume.
Solution Approach 2:
The patent changes the vibration attenuation parameters by introducing a damper with specific damping characteristics. The damper provides an attenuation force that corresponds to the displacement of the supporting member connecting part, effectively controlling the horizontal vibration amplitude to prevent collision while maintaining compact design.
2Device complexity
If the outer tub is allowed to vibrate horizontally, then the supporting structure remains simple, but collision with the casing occurs and noise increases
Solution Approach 1:
The horizontal vibration buffering device acts as an intermediary between the simple supporting structure and the harmful effects of collision and noise. The damper within this device provides attenuation force to reduce horizontal vibrations at the source, preventing collision with the casing and reducing noise generation while maintaining relative simplicity of the overall supporting structure.

AI summary
A laundry treatment apparatus includes a casing; an outer tub; a supporting member coupling the outer tub to the casing; and at least one horizontal vibration buffering device connecting the supporting member with a side surface of the casing. The horizontal vibration buffering device includes a casing connecting part coupled to the casing; a supporting member connecting part coupled to the supporting member, and a damper. The supporting member connecting part has a displacement relative the casing connecting part as the outer tub vibrates. The damper provides an attenuation force corresponding to the displacement of the supporting member connecting part relative the casing connecting part.
