Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing ozone generators with multiple discharge gaps face challenges in achieving uniform power input due to varying gap widths and temperature differences, leading to inefficiencies in ozone production and increased energy consumption.
Innovation Solution
A device with at least two high-voltage electrodes and one ground electrode, where dielectrics are arranged between each high-voltage and ground electrode, allowing for different voltages to be applied across each discharge gap to ensure uniform power input, using a transformer with taps or separate power supplies for each gap, and optionally using filler materials to adjust gap capacity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If multiple discharge gaps with identical gap width are used to achieve uniform power input, then power distribution is improved, but manufacturing precision becomes extremely difficult to realise
Solution Approach 1:
The patent applies local quality by allowing different gap widths in different discharge gaps rather than requiring uniform gap widths across all gaps. Each gap can be optimized independently for its specific position and function, making the device easier to manufacture while still achieving uniform power input through compensating voltage adjustments.
2Manufacturing precision
If different voltages are applied to each gap according to individual gap width, then power input uniformity is improved, but device complexity increases
Solution Approach 1:
The patent changes the electrical parameter (voltage) applied to each discharge gap according to its specific gap width. By adjusting the voltage parameter independently for each gap, the system compensates for manufacturing variations and achieves uniform power input across all gaps, resolving the contradiction between precision and complexity.
3Volume of moving object
If concentric tube structure is used for electrode assembly, then device compactness is improved, but gap width control precision deteriorates
Solution Approach 1:
The patent maintains the compact concentric tube structure but applies local quality by allowing different gap widths at different locations within the concentric arrangement. This enables each gap to be optimized independently while preserving the space-efficient concentric configuration.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
This approach reduces specific energy consumption and enhances ozone generation performance by ensuring consistent power input across all gaps, optimizing energy use and production efficiency.
Implementation Method 1
between each high-voltage electrode and ground electrode a dielectric is arranged
Implementation Method 2
ozone can be generated by silent electrical discharge in an oxygen-containing gas. Silent electrical discharge is, in contrast to spark discharge, to be understood as a stable plasma discharge or corona discharge. Molecular oxygen is dissociated into atomic oxygen.
Implementation Method 3
The reactive oxygen atoms subsequently attach themselves to molecular oxygen in an exothermic reaction and form tri-atomic molecules, i.e. ozone. The ozone yield depends inter alia on the electric field strength and operating temperature.

AI summary
A device for generating ozone from oxygen-containing gas by silent electric discharge. At least two high-voltage electrodes and at least one ground electrode are nested. A discharge gap is defined between each high-voltage electrode and adjacent ground electrode. A dielectric is arranged in each discharge gap. In one embodiment, at least two discharge gaps are traversed by the gas, and a different voltage is applied to each gap according to the individual gap width. In another embodiment, filler material is arranged in an interstice between the high-voltage electrode and the corresponding dielectric, and the same amount of power is applied to each discharge gap.
