Front-Loading Washer Door Frame Dispenser to Prevent Percolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Front-loading laundry washing machines face issues with water and washing agent percolation, limited visibility of the laundry, uncomfortable agent pouring, and space constraints due to integrated dispensers in the door porthole glass, leading to leakage and ergonomic challenges.
Innovation Solution
A front-loading washing machine design featuring an extractable washing agent dispenser housed in the door frame, allowing easy access and pouring with the door closed, and a hydraulic system for efficient agent delivery, reducing percolation and enhancing ergonomics.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If the washing agent dispenser is built in the porthole glass, then the door structure is compact, but water and washing agent percolation occurs onto the floor
Solution Approach 1:
The washing agent dispenser is extracted from the porthole glass and relocated to the door frame. This separation eliminates the percolation problem caused by integrated dispensers in the porthole glass, while the door frame housing provides adequate structural space for the dispenser.
2Area of stationary object
If the washing agent dispenser is built in the porthole glass, then the door structure is compact, but visibility of the internal portion of the rotary drum is obstructed
Solution Approach 1:
The dispenser is removed from the porthole glass area and positioned in the door frame. This extraction clears the porthole glass of obstructions, restoring full visibility of the drum interior while maintaining door structural integrity.
3Device complexity
If the washing agent dispenser is in a relatively low position, then the door structure is simplified, but pouring washing agents becomes uncomfortable
Solution Approach 1:
The dispenser is repositioned from a low vertical position to an elevated position in the door frame. This dimensional change in vertical placement improves ergonomics for pouring washing agents while the door frame structure maintains overall simplicity.
4Stability of the object's composition
If the washing agent dispenser is permanently associated with the washing machine, then the machine structure is integrated, but pouring washing agents requires the door to be open and occupies much room
Solution Approach 1:
The dispenser is segmented as a separate, extractable component from the main machine body. It can be removed from the door frame housing, allowing users to pour washing agents into it outside the machine, thereby reducing the space required for the loading operation.
