Solution Overview
Problem
Existing antibacterial cleaning machines with wet filters require expensive silver electrodes and power supplies, leading to increased production costs and decreased efficiency over time, necessitating frequent replacements.
Innovation Solution
Incorporation of a silver/silver alloy ring-shaped sanitizing element immersed in the water tank, which continuously releases antibacterial ions without the need for electrodes or power supplies, using typical plastic materials and ensuring consistent antibacterial action through periodic replacement.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If silver electrodes and power supply units are used to achieve antibacterial action, then effective antibacterial and sanitizing action is obtained, but device complexity and production cost increase
Solution Approach 1:
The patent extracts and removes the power supply unit and electrode components from the cleaning machine, retaining only the essential water filter tank. This eliminates the complex electrical subsystem while preserving the core antibacterial function through the water filter medium itself, thereby reducing device complexity without sacrificing antibacterial effectiveness
Solution Approach 2:
The patent employs a disposable water filter tank containing silver-based antibacterial material that can be replaced periodically. This eliminates the need for expensive, complex, and maintenance-intensive electrode assemblies with power supplies, achieving cost-effective antibacterial protection through simple, replaceable consumable components
2Reliability
If silver electrodes and power supply units are used to achieve antibacterial action, then effective antibacterial and sanitizing action is obtained, but production cost increases
Solution Approach 1:
The patent replaces expensive silver electrodes and power supply units with an affordable disposable water filter tank containing silver-based antibacterial material. This dramatically reduces production costs while maintaining effective antibacterial function, making the technology economically viable for mass-market cleaning machines
Solution Approach 2:
By removing the expensive electrical subsystem (power supply and electrodes) and retaining only the essential water filter tank with antibacterial properties, the patent significantly reduces bill of materials cost and assembly complexity, thereby lowering production costs while preserving core antibacterial functionality
3Reliability
If electrodes are used to achieve antibacterial action, then antibacterial effect is amplified, but watertight connections and maintenance requirements increase
Solution Approach 1:
The patent removes the electrode assembly and power supply unit from the system, eliminating all associated watertight connection requirements and electrical maintenance needs. The simplified water filter tank design requires no electrical connections, thereby eliminating a major source of maintenance problems and repair complexity
Solution Approach 2:
By采用 disposable water filter tanks instead of permanent electrode assemblies, the patent eliminates long-term maintenance requirements. Users simply replace the entire tank when needed, avoiding complex repair procedures involving electrical connections, seal replacements, and component reassembly
