Dual-Cavity Detergent Dispenser for Individual Liquid Dosing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing washing machine delivery devices lack sufficient storage capacity for liquid washing products and fail to simultaneously handle different types of products efficiently, impacting user convenience.
Innovation Solution
A delivery device with a detergent container, dispenser, and pump system that includes placing cavities, inflow and outflow openings, and a unidirectional valve, allowing for increased storage and simultaneous suction and delivery of various liquid washing products, forming an automatic delivery structure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a single placing cavity is used in the dispenser, then the device structure remains simple, but the storage capacity for liquid washing products is insufficient and only one type of product can be handled at a time
Solution Approach 1:
The dispenser is divided into multiple placing cavities (first placing cavity and second placing cavity) that are spatially separated. Each cavity can independently store different types of liquid washing products, allowing simultaneous storage of multiple products while maintaining a relatively simple overall structure. The pump system is also segmented with separate inflow openings for each cavity.
2Adaptability or versatility
If only one inlet is provided in the detergent container, then the pump structure remains simple, but different types of washing products cannot be delivered individually
Solution Approach 1:
The pump is equipped with multiple inflow openings (first inflow opening and second inflow opening) that correspond to different placing cavities. This segmentation allows the pump to selectively draw different types of washing products from different cavities based on washing needs, enabling individual delivery of multiple product types while maintaining a relatively simple pump structure.
3Ease of operation
If the dispenser is fixed in the withdrawal space, then the structure remains simple, but the user cannot easily access and refill the washing products
Solution Approach 1:
The dispenser is designed to be movable within the withdrawal space rather than fixed. It can be pulled out for user access and refilling operations, and then pushed back to its original position for reliable sealing and delivery operations. This dynamic design balances user convenience with system reliability.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enhances storage capacity and user comfort by enabling simultaneous suction and individual delivery of different washing products, improving the reliability and efficiency of the delivery process.
Implementation Method 1
a pump including two inflow openings connected with two liquid discharge channels correspondingly, and two outflow openings connected with the first inlet and the second inlet respectively
Implementation Method 2
the closure member normally closes the liquid discharge channel, and the closure member is opened when each of the inflow openings and the corresponding liquid discharge channel cooperate to suck the liquid
Implementation Method 3
the first spring has two ends abutting against an inner wall of the dispenser and the first valve body respectively, to normally push the first valve body to cooperate with the sealing member, so as to seal an internal space of the sealing member
Implementation Method 4
the second spring has a first end abutting against the dispenser or the hook seat, and a second end abutting against the retaining hook to normally push the protrusion to extend out of the protrusion hole
Implementation Method 5
the unidirectional valve is arranged adjacent to the water inlet and configured to allow water to unidirectionally flow into the flow space through the water inlet
