Washing Machine Cover Drive Layout for Worktable Space Saving
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machine designs face challenges in efficiently arranging the worktable space due to the placement of the driving motor, which occupies valuable space and hinders the arrangement of other components like the detergent dispenser.
Innovation Solution
The washing machine incorporates a driving motor positioned at the corner of the worktable with an upwardly extending ear, allowing the motor to be recessed and reducing its footprint, along with a one-way bearing mechanism for smooth and safe operation of the electric door, enabling improved automation and user experience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If the driving motor is mounted close to the center of the worktable, then the electric door opening function is achieved, but the arrangement efficiency of other electric devices in the worktable is affected
Solution Approach 1:
The driving motor is extracted from the central worktable area and relocated to the corner position. The motor portion is disposed at the corner of the worktable, with the reducer portion extending upwardly beyond the work surface, thereby removing the space occupation conflict in the central worktable area and enabling better arrangement of other electric devices.
Solution Approach 2:
The motor arrangement transitions from a two-dimensional planar layout to a three-dimensional configuration. The motor portion is positioned at the corner while the reducer portion extends vertically upward beyond the work surface, utilizing the vertical dimension to resolve the horizontal space conflict and improve worktable space arrangement efficiency.

Solution Approach 1:
The driving motor is extracted from the central worktable area and relocated to the corner position. The motor portion is disposed at the corner of the worktable, with the reducer portion extending upwardly beyond the work surface, thereby removing the space occupation conflict in the central worktable area and enabling better arrangement of other electric devices.
Solution Approach 2:
The driving motor is segmented into two distinct portions: the motor portion disposed at the corner of the worktable and the reducer portion extending upwardly beyond the work surface. This segmentation allows each portion to be optimally positioned, reducing overall space occupation and facilitating better component arrangement.
