Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the electrolytic cell is switched on continuously to ensure disinfection, then disinfection effectiveness is improved, but health hazards increase due to ozone release without water flow

Engineering Contradiction:

Improvedisinfection effectivenessVSAvoidozone release health hazards

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The control unit continuously monitors the water flow rate through the electrolytic cell and automatically adjusts the supply voltage based on the detected flow conditions. When water flow is detected, the cell is switched on for disinfection; when flow stops, the cell is switched off to prevent ozone release, creating a closed-loop feedback system that resolves the contradiction between continuous disinfection and ozone safety

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system uses the water flow itself as the triggering mechanism for ozone generation. The flowing water automatically activates the electrolytic cell through the flow sensor, and the cessation of flow automatically deactivates it, making the system self-regulating without external intervention or additional mechanical components

Inventive Principle:

Principle #25Self-service

2Device complexity

If manual switching is used for the electrolytic cell, then device complexity is reduced, but operational reliability deteriorates due to human error in switching on and off

Engineering Contradiction:

Improvecontrol system simplicityVSAvoidoperational reliability

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system automatically detects water flow conditions and switches the electrolytic cell on or off accordingly, eliminating the need for manual intervention. The flow sensor and control unit work together to make the system self-regulating, ensuring reliable operation without human error while maintaining relative simplicity

Inventive Principle:

Principle #25Self-service

3Reliability

If additional mechanical components like flow switches are added for automatic control, then operational reliability is improved, but device complexity and manufacturing costs increase

Engineering Contradiction:

Improveautomatic control reliabilityVSAvoidmechanical component quantity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent replaces traditional mechanical flow switches with an electronic flow detection system that uses the water flow rate itself to trigger the control unit. This electronic approach eliminates complex mechanical moving parts while achieving reliable automatic control, reducing device complexity and manufacturing costs

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The control unit serves multiple functions: it monitors water flow rate, detects flow conditions, determines when to switch the electrolytic cell on or off, and manages the supply voltage. This multi-functional integration eliminates the need for separate mechanical flow switching components, simplifying the overall device

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

The invention relates to a method for controlling an electrolytic cell (3) for the electrolytic production of ozone, which can be switched between a switched-off and a switched-on state and through which water can flow, with a change in the water flow rate in the electrolytic cell (3) triggering a signal which is a control unit is transmitted and the control unit switches a supply voltage of the electrolytic cell (3) on or off. It is provided that the signal is triggered by a change in a potential difference, which is measured between two measuring points within the volume of the electrolytic cell (3) through which flow occurs. In addition, a device for disinfecting water using this method is shown.
