Washing Machine Suspension Module for Horizontal Vibration Buffering
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines are ineffective in attenuating horizontal vibrations, leading to operational disruptions when eccentricity occurs in the interior container, as the existing suspension systems primarily focus on vertical vibration reduction.
Innovation Solution
The washing machine incorporates a suspension module with both vertical and horizontal suspension systems, along with a holder mechanism that utilizes a reduction member to buffer vibrations and reduce noise by providing elastic force, allowing relative movement between the vertical and horizontal suspensions to effectively manage vibrations in multiple directions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If the suspension system is optimized for vertical vibration reduction, then vertical stability is improved, but adaptability to horizontal vibrations deteriorates
Solution Approach 1:
The suspension system achieves multi-functionality by incorporating both vertical and horizontal suspension units that work together. The system can now handle both vertical and horizontal vibrations, making it adaptable to various vibration conditions including eccentricity events, while maintaining vertical stability through the dedicated vertical suspension unit.
2Device complexity
If a simple vertical suspension system is used, then device complexity is reduced, but vibration buffering effectiveness in multiple directions deteriorates
Solution Approach 1:
The suspension system is divided into modular vertical and horizontal units, each with a specific function. This segmentation makes the overall complex system manageable through standardized, independent components that can be manufactured and assembled separately.
Solution Approach 2:
The invention extends the suspension system from one dimension (vertical) to two dimensions (vertical and horizontal) by adding the horizontal suspension unit. This dimensional expansion enables multi-directional vibration buffering while maintaining a relatively simple structural approach.

AI summary
A washing machine includes a casing, an exterior container disposed within the casing, configured to store washing water for washing, and supported to the casing, and a suspension module disposed between the exterior container and the casing and configured to buffer a vibration transferred from the exterior container to the casing. The suspension module includes a holder disposed between a horizontal suspension and a vertical suspension and configured to generate a relative movement in a length direction and to perform buffering on a vibration in a direction that crosses the length direction when the vibration is reduced.
