Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing laundry processing devices face issues with horizontal vibration damping, as solid bar vibration prevention members transfer vibrations to suspension units, leading to potential breakage and damage at connecting portions.
Innovation Solution
A stabilizer with fixing members, an elastic connecting member, and a damping member that absorbs horizontal vibrations by using a cover portion with bent ends passing through a damping portion, distributing force across supporting rods to minimize damage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a solid bar vibration prevention member is used, then the structure is simple, but the horizontal vibration is not absorbed and is transferred to the suspension unit causing potential breakage
Solution Approach 1:
The vibration prevention member changes from a solid bar form to a rod-shaped elastic body form, fundamentally changing its mechanical properties from rigid to elastic. This allows the member to absorb horizontal vibrations through elastic deformation while maintaining structural simplicity, preventing vibration transfer to the suspension unit and avoiding breakage.
Solution Approach 2:
The vibration prevention member is constructed as a composite structure with an outer circumferential surface layer having different elastic modulus characteristics than the inner core. This composite structure enables effective horizontal vibration absorption through controlled elastic deformation while maintaining overall structural integrity and simplicity.
2Reliability
If the vibration prevention member is made of elastic material, then horizontal vibration absorption is improved, but the manufacturing complexity increases
Solution Approach 1:
The invention specifies particular ranges for elastic modulus parameters (outer layer: 0.01-10 MPa, inner core: 0.1-100 MPa) to achieve effective vibration absorption. By controlling these material parameters within specific ranges, the invention balances vibration absorption performance with manufacturability, allowing standard elastic materials to be used without excessive manufacturing complexity.
Solution Approach 2:
The vibration prevention member has different material properties at different locations - the outer circumferential surface layer has lower elastic modulus for vibration absorption, while the inner core has higher elastic modulus for structural support. This local differentiation of material quality enables effective vibration absorption while maintaining overall structural integrity and ease of manufacture using layered construction methods.

This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The stabilizer effectively minimizes the risk of support rod breakage and improves vibration absorption by distributing horizontal vibrations across multiple supporting rods, reducing the likelihood of damage and enhancing overall stability.
Implementation Method 1
a connecting member which is connected to the fixing member and is elastically deformed by force in a horizontal direction which allows the tub to be vibrated in the horizontal direction
Implementation Method 2
a friction force which offsets the force in the horizontal force between the bent portion and the damping portion by the bent portion relatively moving in the horizontal direction with respect to the damping portion
