Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional washing machines are inefficient for removing partial contamination from clothes, as they require large amounts of water and energy, and can damage delicate fabrics, while existing contamination suction devices struggle with operability and effectiveness, especially in removing absorbed stains.
Innovation Solution
A portable clothes care device with a collection box, suction pipe, and spray nozzle that allows for one-handed operation, using a small amount of water to spray and suction contaminants, with interchangeable washing covers to manage different types of contamination, and can be integrated with a clothes care apparatus for enhanced functionality.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If a washing machine is used to remove partial contamination, then the contaminated area can be treated, but large amounts of water and energy are required and the process takes a long time
Solution Approach 1:
The invention segments the decontamination process into localized treatment zones using multiple spray nozzles and suction ports arranged in specific patterns. This allows targeted treatment of contaminated areas rather than treating the entire garment, significantly reducing water and energy consumption while maintaining high decontamination efficiency.
Solution Approach 2:
The device applies partial action by concentrating spray and suction forces only on contaminated regions through selectively positioned nozzles and ports. The spray nozzle array and suction port configuration enable treatment of only the necessary areas, avoiding waste of water and energy on clean portions of the clothes.
2Loss of time
If a washing machine is used to remove partial contamination, then the contaminated area can be treated, but the process is wasteful and time-consuming
Solution Approach 1:
The device maintains continuous useful action through coordinated operation of spray nozzles and suction ports. The spray nozzle sprays washing water while suction ports simultaneously remove contaminated water, creating a continuous decontamination process that reduces total treatment time and energy consumption compared to traditional batch washing.
Solution Approach 2:
By applying treatment forces only where contamination exists through strategically positioned nozzles and ports, the device achieves rapid decontamination of targeted areas without the energy and time waste associated with treating entire garments in a washing machine.
3Quantity of substance
If a contamination suction device is used to remove stains, then water consumption is reduced, but it is difficult to remove absorbed stains
Solution Approach 1:
The device segments the spray and suction functions into multiple distributed nozzles and ports, allowing washing water to penetrate absorbed stains from multiple angles while suction simultaneously removes the released contamination. This segmented approach enhances stain removal effectiveness for absorbed contaminants while maintaining low water consumption.
Solution Approach 2:
The spray nozzle array delivers washing water to pre-treat and loosen absorbed stains before suction removes them. This preliminary spraying action prepares the contamination for effective removal, enabling the device to handle both surface and absorbed stains with minimal water usage.
4Ease of operation
If a conventional spray nozzle is used, then water can be sprayed on contamination, but the spray pattern is not optimized for effective contamination removal
Solution Approach 1:
The spray function is segmented into multiple nozzles arranged in specific patterns, creating an optimized spray distribution that effectively covers contaminated areas. This segmented nozzle array improves contamination removal effectiveness while maintaining ease of operation through automated or simple manual control.
Solution Approach 2:
The spray nozzle configuration provides local quality optimization by positioning nozzles to deliver water precisely where contamination exists. The varied nozzle positions and angles create tailored spray patterns for different contamination types and locations, enhancing removal effectiveness while keeping the device easy to operate.

AI summary
A clothes care device is provided. The clothes care device includes a collection box, a suction pipe, a washing cover, and a spray nozzle disposed inside the suction pipe and provided in such a way that an end of the spray nozzle faces a washing port, and the washing cover mounted to the washing port and provided to be pressed against clothes. By operating a washing water supply in a state in which the washing cover is pressed against the clothes by an operation of a suction device, the spray nozzle sprays washing water and the suction device suctions and collects the washing water.
