Auxiliary Washing Device With Recirculating Sprinkler
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing auxiliary washing devices for textile items suffer from poor efficiency in treatment quality and resource utilization, such as excessive water and energy consumption, and inefficient detergent use due to direct application and handling of detergents.
Innovation Solution
An auxiliary washing device with a sprinkler member that recirculates water and applies it in a rain-like fashion, combined with a detergent dispenser to mix and dissolve detergents efficiently, reducing water usage and foam formation while maintaining effective agitation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If detergent is poured directly on items inside the cylindrical agitator, then the device is simple to operate, but excessive foam forms and detergent exploitation is non-efficient
Solution Approach 1:
A detergent dispenser device is introduced as an intermediary component between the user and the washing tub. The dispenser includes a receptacle for holding detergent and a delivery mechanism that releases detergent into the washing bath at controlled rates, preventing direct pouring and excessive foam formation while improving detergent utilization efficiency
Solution Approach 2:
The detergent is pre-loaded into a receptacle of the dispenser device before the washing cycle begins. The dispenser then automatically delivers the detergent into the washing bath at the appropriate time and at a controlled rate, eliminating the need for users to pour detergent directly during operation
2Device complexity
If water is loaded directly into the tub with items, then the washing process is simple, but water consumption is excessive and treatment quality is poor
Solution Approach 1:
A sprinkler member is introduced as an intermediary device between the water supply and the items in the washing tub. The sprinkler member distributes water in a rain-like fashion over the items, improving water distribution efficiency and reducing overall water consumption while maintaining effective washing action
Solution Approach 2:
The direct water loading mechanism is supplemented with a sprinkler system that uses controlled water distribution to replace the inefficient method of simply filling the tub. This substitution improves water utilization efficiency without significantly increasing device complexity
3Volume of moving object
If the auxiliary device has small dimensions to fit under the main machine, then space utilization is improved, but treatment quality and resource efficiency deteriorate
Solution Approach 1:
The invention changes the operational parameters of the auxiliary device by implementing controlled water delivery rates and detergent delivery rates through the sprinkler member and dispenser. These parameter changes enable effective washing treatment within a compact volume, improving treatment quality without requiring larger device dimensions
