Pet Water Dispenser Electrolysis Sterilization for Shaded Areas
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing pet water dispensers using ultraviolet rays for sterilization have limited effectiveness due to restricted irradiation range and vulnerability to environmental factors, failing to adequately sterilize shaded or complex-shaped areas and leading to unsatisfactory disinfection results.
Innovation Solution
A pet drinking device equipped with an electrolysis module that generates active substances like ozone during water circulation for comprehensive sterilization and disinfection, combined with a filter element assembly to enhance water quality, including antibacterial and deodorizing filters.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If ultraviolet rays are used for sterilization, then the water in directly irradiated zones can be sterilized, but the sterilization effect in shaded portions, occluded areas, or interiors of complex-shaped objects is insufficient
Solution Approach 1:
The patent changes the sterilization method from ultraviolet irradiation to electrolysis, fundamentally altering the physical-chemical parameters of the water treatment process. The electrolysis module generates active substances through electrochemical reactions, enabling penetration into areas where ultraviolet light cannot reach, thus resolving the contradiction between sterilization reliability and coverage of complex areas
Solution Approach 2:
The patent replaces the optical field-based ultraviolet sterilization system with an electrochemical field-based electrolysis system. This substitution allows the generation of active substances that can diffuse and penetrate into occluded areas and complex geometries, overcoming the limitation of ultraviolet rays being blocked by physical obstructions
2Device complexity
If ultraviolet rays are used for sterilization, then the process is simple, but the sterilization efficacy declines due to environmental factors like dust and humidity
Solution Approach 1:
The patent transitions from optical field sterilization to electrochemical field sterilization through electrolysis. This parameter change makes the sterilization process independent of environmental optical conditions, as the electrolysis process generates active substances through electrical current and chemical reactions that are not affected by dust or humidity in the same way ultraviolet light is
Solution Approach 2:
The patent introduces active substances (such as ozone, hydrogen peroxide, and other oxidizing agents) as intermediaries in the sterilization process. These substances are generated through electrolysis and serve as the actual sterilizing agents, replacing direct ultraviolet irradiation. This intermediary approach allows sterilization to occur through chemical action that can penetrate and affect microorganisms in ways that direct light cannot
