Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing gas generating apparatuses face issues with corrosion of components due to electrolyzed water, leading to reduced operational safety and efficiency, as well as ineffective heat dissipation, which shortens the device's lifespan.
Innovation Solution
A gas generating apparatus with a separated water pump system, where a drive motor outside the electrolyzed water drives a stirring fan to promote water flow, utilizing a cooling tube with a copper powder sintered surface for enhanced heat dissipation and preventing motor corrosion, while maintaining mechanical independence from the stirring fan.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Temperature
If a stirring device is used to promote water flowing for heat dissipation, then cooling efficiency is improved, but the corrosion characteristic of electrolytes rapidly decreases the use period of the stirring device
Solution Approach 1:
The patent divides the water pump into two separate components: the stirring fan (immersed in electrolyzed water) and the drive motor (positioned outside the electrolyzed water). This segmentation allows the stirring function to remain effective for cooling while the motor is protected from corrosive electrolyte contact, resolving the contradiction between cooling efficiency and device durability
Solution Approach 2:
The patent introduces a non-mechanical connection (magnetic coupling or electromagnetic induction) as an intermediary between the drive motor and the stirring fan. This intermediary transmission method allows the motor to drive the fan without direct mechanical contact with the electrolyzed water, preventing corrosion while maintaining the stirring and cooling functions
2Device complexity
If the drive motor is placed inside the electrolyzed water to directly drive the stirring fan, then device complexity is reduced, but the drive motor is corroded by electrolyzed water
Solution Approach 1:
The patent segments the drive motor and stirring fan into separate locations - the motor outside the electrolyzed water and the fan inside. This spatial segmentation protects the motor from corrosion while maintaining functional integration, addressing both reliability and operational safety concerns
Solution Approach 2:
The patent replaces direct mechanical connection with non-mechanical transmission methods (magnetic coupling or electromagnetic induction). This substitution eliminates the need for mechanical seals or direct contact between the motor and electrolyzed water, preventing corrosion while maintaining efficient power transmission
