Washing Machine Door Prop with Moisture Absorption to Prevent Mold
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Washing machines, particularly front-loading washers, are prone to mold and mildew formation due to wet environments, leading to unpleasant odors and reduced appliance life, with existing solutions being inconvenient or ineffective.
Innovation Solution
A combination of a door prop and moisture-absorbing mechanism, including a central wand with a drying attachment and a moisture-absorbing module, to keep the door open and reduce ambient moisture, preventing mold and mildew growth.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the washer door is left ajar to prevent mold and mildew, then mold and mildew formation is reduced, but the door may slam shut or it is inconvenient for the user
Solution Approach 1:
The door engagement system automatically maintains the door in an open position without requiring user intervention. The system uses a spring-loaded arm with a roller that engages with the door edge, providing automatic self-servicing functionality to keep the door ajar and prevent mold formation without user effort.
Solution Approach 2:
A door engagement system acts as an intermediary mechanism between the door and the user. The system includes a spring-loaded arm with a roller that mediates the door's position, holding it open through mechanical engagement while allowing easy disengagement when needed.
2Reliability
If manual drying of the gasket and drum is performed, then moisture is removed reducing mold risk, but it requires additional user effort and time
Solution Approach 1:
The system performs preliminary drying action by positioning absorbent materials (towels or paper towels) inside the drum and against the gasket before the user leaves. This preliminary placement of drying materials automatically continues to absorb moisture without requiring the user to manually dry surfaces.
Solution Approach 2:
Absorbent materials placed within the drum and against the gasket perform self-service drying functionality. The materials automatically absorb moisture from the drum interior and gasket surfaces without requiring ongoing user intervention or manual wiping actions.
3Reliability
If absorbent materials are placed in the drum to absorb moisture, then ambient moisture is reduced preventing mold, but the materials need to be replaced or repositioned
Solution Approach 1:
The system uses inexpensive, disposable absorbent materials such as paper towels that are placed inside the drum. These materials are designed for single-use or limited-use periods, after which they are discarded and replaced. This approach prioritizes ease of replacement over durability, using cheap materials that effectively absorb moisture but do not require complex maintenance or cleaning.
