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 as the gap between the casing and the outer tub decreases to maximize space.
Innovation Solution
The implementation of a pair or four horizontal vibration buffering devices arranged to form opposite angles relative to each other, which couple with the outer tub and provide attenuation forces through displacement, utilizing a combination of springs and dampers to mitigate 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 improved, but the horizontal vibration increases causing collision between the outer tub and the casing
Solution Approach 1:
The vibration buffering function is segmented into multiple independent horizontal vibration buffering devices arranged at opposite angles, with each device handling specific vibration components. This segmentation allows targeted mitigation of horizontal vibrations while preserving the reduced gap configuration for maximizing outer tub volume.
Solution Approach 2:
Horizontal vibration buffering devices are introduced as intermediary elements between the outer tub and the casing. These devices include buffers and dampers that absorb and dissipate horizontal vibration energy, preventing direct collision between the outer tub and casing while allowing the outer tub to maintain its optimized volume.
2Device complexity
If the outer tub is allowed to vibrate horizontally, then the structure remains simple, but collision with the casing occurs increasing noise and reducing durability
Solution Approach 1:
Horizontal vibration buffering devices are installed in advance between the outer tub and casing to provide preemptive cushioning against horizontal vibrations. The buffers and dampers are pre-positioned to absorb vibration energy before it can cause collision, thereby protecting the system and preventing noise and durability issues while maintaining structural simplicity.
