Washer Pump Mount Structure for Vibration Damping
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treating apparatuses, such as drum washing machines, face challenges with narrow component installation spaces, high costs due to multiple components, and increased vibrations from the mounting of pump units.
Innovation Solution
A laundry treating apparatus design that integrates a pump unit with a mount directly coupling it to the cabinet, reducing vibrations and optimizing space for automatic injection devices, while minimizing the number of components to lower costs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mounting plate and multiple screws are used to fasten the pump unit, then the pump unit is securely fixed, but the component installation space becomes narrow and the cost increases
Solution Approach 1:
The mounting plate and multiple screws are merged into a single integrated mount structure. The mount is formed as one piece with vibration-absorbing protrusions that directly engage with the pump unit housing, eliminating the need for separate fastening components while maintaining secure fixation.
Solution Approach 2:
The integrated mount serves multiple functions simultaneously: it provides structural support for the pump unit, absorbs vibrations through its elastic protrusions, and eliminates the need for separate mounting hardware. This multi-functionality reduces the total component count while improving reliability.
2Reliability
If a mounting plate with multiple screws is used, then the pump unit is firmly secured, but the installation cost increases
Solution Approach 1:
Multiple discrete components (mounting plate and screws) are combined into a single integrated mount structure that can be manufactured as one piece through injection molding or similar processes, reducing assembly steps and manufacturing costs.
Solution Approach 2:
The integrated mount uses inexpensive elastic material (such as rubber or polymer) to create vibration-absorbing protrusions that provide secure fixation without requiring expensive metal fasteners, reducing overall component cost.
3Reliability
If multiple components (mounting plate and screws) are used, then the pump unit is securely fastened, but vibrations are not effectively reduced
Solution Approach 1:
The mount incorporates elastic vibration-absorbing protrusions that are pre-designed to cushion and dampen vibrations before they can be transmitted to the pump unit housing. This beforehand cushioning prevents vibration-related problems rather than addressing them after they occur.
Solution Approach 2:
The integrated mount combines rigid structural elements with elastic vibration-absorbing material in a single component. The rigid portions provide secure mechanical attachment while the elastic portions absorb vibrations, creating a composite structure that addresses both fixation and vibration reduction needs.
