Corrugated Drain Hose Coupling for Washer Pump Vibration Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Vibration noise from drain pumps in washers is transmitted to the drain hoses and frames, causing unwanted vibration and noise during operation, which existing technologies have not effectively addressed.
Innovation Solution
An anti-vibration member with a corrugation part is connected between the drain pump and the drain hose, absorbing vibration energy through deformation, reducing noise transmission. The anti-vibration member is formed of different materials than the drain hose and includes a sleeve for reinforcement, connected via heat fusion, allowing for effective vibration absorption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If a rigid connection is used between drain pump and drain hose, then structural strength is improved, but vibration noise transmission increases
Solution Approach 1:
The patent introduces an anti-vibration member as an intermediary component between the drain pump and drain hose. This member includes a pump connection part, a hose connection part, and a corrugation part that acts as a vibration-absorbing intermediary, preventing direct rigid connection while maintaining structural integrity
Solution Approach 2:
The anti-vibration member utilizes a corrugation part with a flexible structure that can deform to absorb vibration. The corrugated design provides flexibility while maintaining sufficient strength, allowing the connection to accommodate vibration without transmitting it directly to the drain hose
2Object-generated harmful factors
If an anti-vibration member with corrugation part is added, then vibration absorption is improved, but device complexity increases
Solution Approach 1:
The patent merges multiple functions into a single anti-vibration member: vibration absorption through the corrugation part, connection to the drain pump via the pump connection part, and connection to the drain hose via the hose connection part. This integration reduces the need for separate vibration damping components and simplifies the overall structure
Solution Approach 2:
The anti-vibration member serves multiple purposes simultaneously: it acts as a vibration absorber, a connector between different components, and a structural support element. The single component performs what would traditionally require multiple separate parts, thereby reducing device complexity

AI summary
A drain hose has a simple structure which absorbs vibration of a drain pump, and a washer has the same. The washer includes a main body, a drain pump disposed at the lower portion of the main body, a drain hose to guide wash water pumped by the drain pump to the outside of the main body, and an anti-vibration member formed of a material differing from the drain hose, and including a corrugation part connected between the drain pump and the drain hose and absorbing vibration of the drain pump during drainage of the wash water.
