Washing Machine Bottom Cover With Integrated Hydraulic Assembly
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines face challenges in assembly time, space utilization, and accessibility of hydraulic elements, leading to inefficiencies and complexities in the installation and maintenance of hydraulic systems.
Innovation Solution
Integration of hydraulic elements such as pumps and wash liquid ducts into the bottom cover of the washing machine, allowing for predetermined positioning and easier assembly, improved space utilization, and reduced noise and vibrations, along with a detachable bottom cover for enhanced accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If hydraulic elements are installed separately in conventional washing machines, then assembly and maintenance require more time and effort, but disassembling the entire appliance is necessary for access
Solution Approach 1:
The patent integrates the hydraulic system with the bottom cover by incorporating pump motors and wash liquid ducts directly into the bottom cover structure. This merging allows hydraulic elements to be accessed by simply removing the bottom cover, eliminating the need to disassemble the entire washing machine while reducing assembly complexity through predetermined positioning.
2Ease of manufacture
If hydraulic elements are positioned freely in the washing machine interior, then installation flexibility is provided, but assembly time and positioning accuracy decrease
Solution Approach 1:
The hydraulic elements (pump motors and wash liquid ducts) are pre-integrated into the bottom cover during manufacturing, with predetermined positioning and interconnection. This preliminary action ensures precise positioning is achieved during manufacturing rather than during final assembly, significantly improving assembly efficiency while maintaining positioning precision.
3Object-affected harmful factors
If pumps are arranged separately from the bottom cover, then maintenance access is difficult, but noise and vibrations are transmitted to the housing
Solution Approach 1:
The pump motors are integrated into the bottom cover structure, which serves as a noise and vibration isolation chamber. This merging provides dual benefits: the bottom cover absorbs and isolates noise and vibrations from the housing, while simultaneously enabling easy maintenance access by simply removing the bottom cover to reach the pumps.
