Articulating Stand Assembly for Top-Load Washer Accessibility
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Top load washing machines with larger capacities face accessibility issues due to increased height, making it difficult for users, especially those of shorter stature, to reach the bottom of the wash basket without assistance.
Innovation Solution
An articulating stand assembly that tilts the washing machine at an angle, allowing the top panel to rotate and lower, creating easier access to the wash basket while maintaining stability and increasing capacity without compromising accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the height of the washing machine is increased to provide larger wash capacity, then the wash capacity is improved, but the accessibility to the bottom of the wash basket deteriorates
Solution Approach 1:
The stand assembly is designed as a dynamic structure with movable linkage arms and follower pins that allow the cabinet to articulate between a first position (normal operation) and a second position (loading/unloading). This dynamic positioning system enables the same washing machine to serve different user needs by changing its orientation, resolving the contradiction between fixed height and variable accessibility.
Solution Approach 2:
The invention changes the operational parameters of the washing machine by introducing articulation capability. The cabinet can be positioned at different angles relative to the vertical direction, effectively changing the accessible height of the wash basket without altering the physical dimensions of the machine. This parameter change allows users of different statures to access the wash basket comfortably.
2Quantity of substance
If the width of the wash basket is increased to provide larger wash capacity, then the wash capacity is improved, but the space required in household deteriorates
Solution Approach 1:
Instead of increasing wash capacity purely in the horizontal plane (width), the invention utilizes the vertical dimension by allowing the cabinet to articulate. The linkage mechanism with guide tracks and follower pins enables the cabinet to tilt forward, effectively using vertical space to improve accessibility while maintaining a compact horizontal footprint, thus resolving the contradiction between capacity and space.
3Quantity of substance
If the height of the washing machine is increased to provide larger wash capacity, then the wash capacity is improved, but the stability of the washing machine deteriorates
Solution Approach 1:
The stand assembly incorporates a dynamic stabilization mechanism where the linkage arms and follower pins work together to maintain stability during articulation. The guide tracks constrain the movement paths, ensuring the cabinet remains stable in both the first and second positions while enabling controlled movement between positions, thus resolving the contradiction between height and stability.
Solution Approach 2:
The linkage mechanism is designed to counterbalance the weight of the cabinet during articulation. The arrangement of linkage arms and follower pins creates mechanical advantage that reduces the effort required to move the cabinet while maintaining stability, preventing the machine from becoming unstable due to its height.

AI summary
A washing machine appliance has a vertical direction, a transverse direction, and a lateral direction and includes a cabinet and a stand assembly. The cabinet defines an opening. The stand assembly supports the cabinet and facilitates movement of the cabinet between a loading position and a washing position. The stand assembly includes a stand defining a guide track, a plurality of linkage arms located within the stand, and a plurality of follower pins. The follower pins may be mechanically coupled to the cabinet and slidably received into the guide track to facilitate movement of the cabinet between the loading position and the washing position.
