Wall-Mounted Drum Washer Rear Panel Drive Layout
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wall-mounted drum-type washing machines face challenges in reducing size and part count due to separate cabinets surrounding driving units, making it difficult to install and interfere with other components or the wall surface.
Innovation Solution
A wall-mounted drum-type washing machine design featuring a rear panel mounted on the wall with a tub, a rotatable drum, and a driving unit connected via a coupling unit that includes a rotation hole and bearing for the driving shaft, allowing the motor to be directly connected to the drum and reducing interference with the wall and other components.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a separate cabinet surrounds the driving unit, then the driving unit is protected and structured, but the size of the washing machine increases and the number of parts increases
Solution Approach 1:
The patent merges the driving unit with the rear panel by directly mounting the motor on the rear panel and integrating the driving shaft coupling into the panel structure. This eliminates the need for a separate cabinet surrounding the driving unit, thereby reducing the overall washing machine size while maintaining structural protection and reliability.
Solution Approach 2:
The rear panel serves multiple functions: it acts as the mounting surface for the motor, provides structural support for the driving unit, and serves as the back wall of the washing machine cavity. This multi-functionality eliminates the need for separate protective cabinets, reducing part count and overall size.
2Reliability
If a separate cabinet surrounds the driving unit, then the driving unit is protected, but the number of parts increases
Solution Approach 1:
The patent combines multiple functions into the rear panel structure itself, eliminating the need for separate protective cabinets and reducing the total number of parts. The motor, driving shaft coupling, and structural support are all integrated into or mounted directly on the rear panel.
Solution Approach 2:
The rear panel is designed as a multi-functional component that provides structural support, motor mounting, driving shaft coupling, and cavity formation. This universality reduces the need for separate protective structures, thereby reducing the number of parts while maintaining reliability.
3Strength
If the driving unit is installed over the installation plate, then the driving unit is supported, but it may interfere with other components or the wall surface
Solution Approach 1:
The patent relocates the driving unit from a horizontal mounting position (over the installation plate) to a vertical mounting position (on the rear panel). This dimensional change allows the driving shaft to extend horizontally through the rear panel, preventing interference with the wall surface while maintaining adequate support through the rear panel's rigid structure.
