Multi-Nozzle Drum Water Injection for Wide-Coverage Washing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines are limited in their ability to inject washing water over a wide area due to the design of the injection unit, which restricts the effectiveness of the washing process.
Innovation Solution
The washing machine incorporates a modified injection unit with multiple nozzles spaced apart and a connector that diverges the water flow path, allowing for even distribution of washing water across the rotating drum, including a pump, integrated hose, and a fixing unit to secure the nozzles, ensuring comprehensive water coverage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Area of stationary object
If a single nozzle is used to inject washing water, then the injection unit structure is simple, but the washing water cannot be injected over a wide area
Solution Approach 1:
The injection unit is divided into multiple nozzles (first nozzle and second nozzle) spaced apart from each other, with each nozzle responsible for injecting water at different positions. This segmentation allows the system to cover a wider area while maintaining manageable structural complexity through modular design.
Solution Approach 2:
A connector with multiple passages is introduced as an intermediary component to distribute washing water to multiple nozzles. The connector receives water from the integrated hose and diverts it through separate passages to each nozzle, enabling wide-area coverage without requiring complex individual water supply lines to each nozzle.
2Area of stationary object
If multiple nozzles are used to inject washing water at different positions, then washing water can be injected over a wide area, but the connector structure becomes more complex
Solution Approach 1:
The connector is designed with multiple passages that serve universal functions - each passage can deliver water to different nozzles, and the same connector structure can accommodate multiple nozzles at different positions. This multi-functionality reduces the need for separate complex structures for each water delivery path.
Solution Approach 2:
Multiple water delivery functions are merged into a single connector component. Instead of having separate water supply mechanisms for each nozzle, the connector combines multiple passages within one structure, simplifying the overall system while maintaining the capability to inject water at multiple positions simultaneously.
3Area of stationary object
If nozzles are spaced away from each other to inject at different positions, then wide area coverage is achieved, but the injection unit requires more space and positioning complexity
Solution Approach 1:
The injection unit is segmented into modular components (nozzles, connector, integrated hose) that can be independently positioned and assembled. This segmentation allows for flexible spacing of nozzles to achieve wide coverage while simplifying installation through modular assembly rather than requiring precise positioning of a monolithic structure.
