Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ion generators fail to effectively generate a controlled trace amount of ozone along with negative or positive ions, as they either produce excessive ozone that is harmful or are unable to generate both ozone and ions simultaneously.
Innovation Solution
An ion generator design featuring a ground electrode with a partially exposed tip on an insulation substrate, allowing a leakage current to flow between the ground and metal electrodes, which generates a controlled amount of ozone and ions, with the area and position of the exposed tip controlling the leakage current and thus the ozone generation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Object-affected harmful factors
If the whole surface of the ground electrode is covered with an insulating resin to minimize ozone generation, then ozone generation is minimized, but the ability to generate a controlled trace amount of ozone is lost
Solution Approach 1:
The insulating film is applied to the ground electrode surface except for a specific local area (the tip portion). This creates different functional zones: the insulated area prevents unwanted discharge and minimizes ozone generation, while the exposed tip area enables controlled leakage current to generate the required trace amount of ozone. This local differentiation resolves the contradiction between minimizing and controlling ozone generation.
2Quantity of substance
If an amplitude restricting means is used to maintain steady power source voltage to generate a steady amount of ozone, then a steady amount of ozone is generated, but only ozone is generated without negative or positive ions
Solution Approach 1:
By creating a localized exposed tip area on the ground electrode rather than uniform insulation, the system enables simultaneous occurrence of two different discharge modes: controlled ozone generation at the exposed tip through leakage current, and ion generation in the broader electrode region. This local differentiation allows both ozone and ions to be generated together, resolving the contradiction between steady ozone control and ion generation capability.

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 design allows for the generation of a controlled trace amount of ozone and ions, enhancing deodorization and sterilization capabilities while ensuring safety by reducing the required voltage and enabling easy adjustment of ozone levels.
Implementation Method 1
since the tip of the ground electrode is not covered with the insulating film, a leakage current can flow between the ground electrode and the metal electrode, and thereby a trace amount of ozone is generated together with generation of ions
Implementation Method 2
a high-voltage electrode that is provided on the insulation substrate and is to be connected with the wire electrode

AI summary
The present invention provides an ion generator that can generate a controlled trace amount of ozone together with negative or positive ions. The ion generator includes an insulation substrate (41), a ground electrode (42) and a high-voltage electrode (43) on the insulation substrate (41), an insulating film (44) formed on the ground electrode (42), and a wire electrode (45). The root of the wire electrode (45) is soldered to the high-voltage electrode (43). The tip of the wire electrode (45) is arranged so as to protrude in a recessed part (41a). The ground electrode (42) has a pair of legs (42a) and (42b) disposed on the insulation substrate (41) at the sides of the recessed part (41a). The legs (42a) and (42b) are parallel to the wire electrode (45) on opposite sides of the wire electrode (45). The insulating film (44) is provided on the surface of the ground electrode (42) to cover the ground electrode (42) except the high-voltage electrode (43) contacting a first terminal (5a), a contact portion (42c) contacting a second terminal (5b) and parts of the legs (42a) and (42b) of tips of the ground electrode (42) that face the tip of the wire electrode (45).
