Laundry treating apparatus having a pump body support leg including a rigid head and a deformable stem
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treating apparatuses, such as drum washing machines, have a narrow component installation space due to the mounting plate and multiple screws, leading to increased costs and vibration issues.
Innovation Solution
The apparatus incorporates a pump unit with a circulation pump and drain pump integrated into a single body, coupled to a mounting system with a vibration-absorbing rubber mount, allowing for reduced vibration and increased space for component installation, while minimizing the number of components and screws.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a mounting plate with multiple screws is used to fasten the pump unit, then the pump unit is securely fastened, but the component installation space becomes narrow and costs increase
Solution Approach 1:
The mounting plate and multiple screws are merged into a single integrated pump body support leg that directly couples the pump unit to the base cover. This eliminates the separate mounting plate and reduces the number of fastening components, thereby increasing component installation space while maintaining secure fastening through the integrated leg structure
Solution Approach 2:
The pump body support leg serves multiple functions: it provides structural support for the pump unit, acts as a mounting fixture, and incorporates vibration absorption capabilities through the rubber material. This multi-functionality replaces the separate mounting plate and screws, reducing component count and installation space requirements
2Reliability
If a mounting plate with multiple screws is used to fasten the pump unit, then the pump unit is securely fastened, but costs increase
Solution Approach 1:
The mounting plate and multiple screws are merged into a single integrated pump body support leg, reducing the number of parts that need to be manufactured, stored, and assembled. This integration simplifies the manufacturing process and reduces overall costs while maintaining secure fastening functionality
Solution Approach 2:
The separate mounting plate and multiple screw fasteners are extracted from the design and replaced with a single integrated support leg structure. This reduction in component count directly lowers manufacturing complexity and cost while preserving the essential fastening function
3Object-affected harmful factors
If rubber mounts are used to absorb vibrations, then vibrations are reduced, but the structure becomes more complex
Solution Approach 1:
The vibration absorption function is merged into the pump body support leg itself by incorporating rubber material directly into the leg structure. This eliminates the need for separate rubber mounts and simplifies the overall mounting structure while maintaining vibration reduction capabilities
Solution Approach 2:
The pump body support leg is constructed from composite materials, specifically rubber, which provides both structural support and vibration absorption properties. This use of composite materials allows a single component to fulfill multiple functions, reducing structural complexity while effectively reducing vibrations
4Reliability
If multiple screws and mounting plates are used, then secure fastening is achieved, but the number of components increases
Solution Approach 1:
Multiple separate components (mounting plate, multiple screws, rubber mounts) are merged into a single integrated pump body support leg. This consolidation maintains secure fastening functionality while dramatically reducing the total number of components in the mounting system
Solution Approach 2:
The mounting system is re-segmented by integrating all fastening and support functions into a single monolithic support leg structure, eliminating the need for multiple discrete components. This re-segmentation simplifies the overall system architecture while preserving essential functions

Function Achieved in This Case
This configuration reduces vibrations, secures space for additional components like the automatic injection device, and lowers costs by simplifying the installation and reducing the complexity of the component layout.
Implementation Method 1
a mount formed of rubber is installed in a corner portion of the mounting plate in order to absorb vibrations of the pump unit
