Ozone Generator With Variable Dielectric Gap
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ozone generators with constant gap width, dielectric capacity, and layer thickness suffer from reduced efficiency at high ozone concentrations due to temperature-dependent power absorption and sputtering effects, leading to decreased robustness and prolonged running-in periods.
Innovation Solution
The ozone generator design features a decreasing dielectric capacity and increasing layer thickness from the inlet to the outlet, along with a narrowing ozonizing gap width, which allows for locally weighted power consumption, reducing temperature excesses and sputtering, and optimizing power absorption for improved efficiency and robustness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If constant dielectric capacity and layer thickness are used throughout the ozone generator, then the structure is simple and easy to manufacture, but efficiency deteriorates at high ozone concentrations due to temperature excesses
Solution Approach 1:
The patent applies local quality by varying the dielectric layer thickness and dielectric capacity along the flow direction. The dielectric layer has different thicknesses in different sections (thinner at inlet, thicker at outlet), creating locally optimized conditions for power absorption and temperature control at each position along the ozonizing gap.
Solution Approach 2:
The patent changes physical parameters (dielectric capacity, layer thickness, gap width) along the flow direction to optimize performance. The dielectric capacity decreases from inlet to outlet, and layer thickness increases, which modifies power absorption characteristics and reduces temperature excesses at high ozone concentrations.
2Productivity
If high power input is applied to generate high ozone concentrations, then productivity increases, but temperature excesses increase causing efficiency to deteriorate
Solution Approach 1:
The patent creates different local conditions along the flow path by varying dielectric properties. The inlet section with thinner dielectric layer accepts higher power input for ozone generation, while the outlet section with thicker layer dissipates heat more effectively, allowing high overall productivity without excessive temperature rise.
Solution Approach 2:
The patent addresses the temperature problem by adding a spatial dimension to the solution. Instead of uniform power distribution, the dielectric layer thickness varies along the flow direction, creating a gradient that distributes heat generation and dissipation across different spatial zones.
3Ease of manufacture
If constant gap width is maintained, then manufacturing is easier, but sputtering effects increase reducing robustness at high ozone concentrations
Solution Approach 1:
The patent applies local quality by making the gap width vary along the flow direction. The gap is narrower at the inlet where ozone generation is most intense and transitions to a wider gap at the outlet, reducing sputtering effects in regions where ozone concentration is highest.
4Productivity
If dielectric capacity is reduced from inlet to outlet, then efficiency improves by reducing power absorption at high concentrations, but manufacturing complexity increases
Solution Approach 1:
The patent implements local quality through a dielectric layer with spatially varying thickness and capacity. This gradient structure optimizes power absorption locally - higher capacity at inlet for efficient ozone generation, lower capacity at outlet to reduce heating and sputtering - while maintaining a manufacturable conical or stepped geometry.

AI summary
The invention relates to an ozone generator, comprising two electrodes and a dielectric layer arranged between the above such that between the dialectic layer and one of the electrodes an ozonizing gap is formed, through which an oxygen-containing gas can be run. In the direction of the flow of the gas, a dielectric capacity (CD) of the dielectric layer of the gas becomes smaller and/or layer thickness of the dielectric layer becomes greater, such that a gap width of the ozonizing gap is greater on the inlet side than the outlet side.
