Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a special device is added to contain antibacterial and disinfectant substances, then antibacterial function is provided, but the substances cannot fully and uniformly contact washing water due to position limitation
Solution Approach 1:
The patent combines the antibacterial substance storage function with the impeller structure itself. The housing cavity is integrated into the impeller, allowing antibacterial substances to be stored within the washing machine structure rather than in a separate external device. This integration enables the substances to be naturally dispersed into the washing water through the impeller's rotation, achieving uniform contact without requiring additional positioning mechanisms.
Solution Approach 2:
The patent utilizes the dynamic rotation of the impeller to distribute antibacterial substances. As the impeller rotates during washing, the substances stored in the housing cavity are naturally dispersed into the washing water, ensuring uniform contact throughout the washing process. This dynamic distribution eliminates the position limitation problem of static containment devices.
2Productivity
If the impeller structure is reconfigured to form a new water passage, then three-dimensional water flow is achieved, but the structure becomes relatively complicated
Solution Approach 1:
The impeller is designed to serve multiple functions simultaneously: it provides the primary washing action through rotation, creates three-dimensional water flow patterns, and houses the antibacterial substance storage cavity. By making the impeller multi-functional, the patent avoids adding separate complex structures for each function, thereby achieving three-dimensional water flow without significantly increasing overall device complexity.
3Device complexity
If antibacterial substances are contained in a fixed position, then the containment function is simple, but the substances are difficult to fully and uniformly contact washing water
Solution Approach 1:
The patent transforms the static containment problem into a dynamic distribution solution. The housing cavity is positioned within the rotating impeller, so that during washing operation, the impeller's rotation naturally disperses the antibacterial substances into the washing water. This dynamic mechanism ensures uniform distribution without requiring complex delivery systems or multiple containment positions.
Solution Approach 2:
The impeller's own rotation during normal washing operation serves to distribute the antibacterial substances. The system uses its inherent washing motion to automatically disperse the substances into the water, eliminating the need for separate distribution mechanisms. The washing process itself performs the dual function of cleaning clothes and distributing antibacterial agents.
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
The solution provides improved washing effects, better water cleanliness, and enhanced antibacterial and disinfectant performance by ensuring thorough mixing of substances with washing water, reducing twining and improving overall washing quality.
Implementation Method 1
a freely rotatable impeller rotating wheel (300) is installed on the impeller rotating shaft (400); water inlets (620) are arranged in the impeller (600); washing water can enter an internal part of the impeller rotating wheel (300) through the water inlets (620)
Implementation Method 2
water outlet holes for generating fountain-shaped water flows are regularly arranged correspondingly on external surfaces of the impeller rotating wheel
Implementation Method 3
the impeller rotating wheel freely rotates under effects of the water flows, so as to reduce twining of clothes, protect clothes, and enhance washing effects of clothes

AI summary
The present disclosure discloses a freely rotating wave wheel having a housing cavity. The freely rotating wave wheel includes an impeller; an impeller rotating shaft is connected to the impeller; a freely rotatable impeller rotating wheel is installed on the impeller rotating shaft; and a housing cavity is arranged inside the impeller rotating wheel, and/or between the impeller rotating wheel and the impeller, and/or between the impeller rotating shaft and the impeller. Antibacterial and disinfectant substances or other substances beneficial to washing effects of clothes can be arranged in the housing cavity. When water enters into the washing machine to wash and rinse clothes, antibacterial and disinfectant substances or other substances beneficial to washing effects of clothes can effectively perform effects to purify water quality and prevent cross infection due to mixed washing of clothes, thereby generating a better washing effect.
