Detergent Drawer Layout Below the Washer Loading Door
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional laundry treatment apparatuses require users to inconveniently lift detergent over the laundry entrance hole to supply it, as the detergent storage is typically located above this point.
Innovation Solution
The apparatus includes a detergent supply unit positioned under the laundry entrance hole, with multiple storage portions and a water supply system that guides water to these storage portions, allowing for efficient detergent distribution directly to the tub, thus reducing the storage height and user inconvenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If the detergent storage unit is located above the laundry entrance hole, then the structure is simple, but the storage height is high causing user inconvenience
Solution Approach 1:
By inverting the detergent storage unit from above to below the laundry entrance hole, the patent reduces the storage height while maintaining structural simplicity. The water supply paths are accordingly inverted to supply water from above to the below-positioned storage unit, resolving the contradiction between structural simplicity and reduced storage height.
2Ease of operation
If the detergent storage unit is positioned below the laundry entrance hole, then the storage height is reduced and accessibility is improved, but the water supply path becomes more complex
Solution Approach 1:
The water supply path is segmented into multiple independent paths (first water supply path, second water supply path, third water supply path) that can operate independently or simultaneously. This segmentation allows the system to supply water to different storage portions flexibly, managing the complexity through modular path design while achieving improved accessibility.
Solution Approach 2:
The water supply paths are designed to be dynamically controllable through distribution valves, allowing the system to adapt water flow to different storage portions based on operational needs. This dynamic control manages path complexity by enabling selective activation of different paths rather than requiring all paths to be permanently active.
