Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional ozone generation apparatuses face limitations in increasing ozone generation volume density without complicating the apparatus or increasing its size, as methods to enhance efficiency, such as shortening discharge gaps and increasing power density, lead to increased costs and complexity.
Innovation Solution
The apparatus incorporates a dielectric partition plate between two electrode parts to create two discharge spaces within a single discharge cell, increasing the number of discharge surfaces and allowing for a higher ozone generation volume density while maintaining a compact and cost-effective design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple discharge cells are laminated to increase ozone generation capacity, then ozone generation amount increases, but apparatus size and complexity increase
Solution Approach 1:
The patent divides a single discharge cell into multiple discharge spaces by introducing partition walls, creating multiple discharge surfaces within one cell. This segmentation allows the system to achieve high ozone generation capacity without laminating multiple cells, thereby reducing apparatus complexity while maintaining productivity.
Solution Approach 2:
The patent nests multiple discharge spaces within a single discharge cell structure, with partition walls creating internal divisions. This nested configuration enables multiple discharge surfaces to coexist in one cell, effectively increasing ozone generation capacity without proportionally increasing the overall apparatus size or complexity.
2Productivity
If discharge gap length is shortened to increase ozone concentration, then ozone generation volume density increases, but manufacturing precision requirements increase
Solution Approach 1:
Instead of uniformly shortening the discharge gap throughout, the patent segments the discharge cell into multiple spaces with partition walls. This allows different discharge gap lengths in different regions, maintaining manufacturing feasibility while achieving high overall ozone generation volume density through increased discharge surface area.
Solution Approach 2:
The patent applies different discharge gap lengths to different local regions within the discharge cell. By creating local variations in gap length through partition walls, the system optimizes ozone generation in each region while maintaining overall manufacturability, avoiding the need for uniformly high precision across the entire apparatus.
3Productivity
If discharge surface area is increased to enhance ozone generation, then ozone generation amount increases, but apparatus volume increases
Solution Approach 1:
The patent transitions from increasing discharge surface area through lateral expansion to achieving it through vertical segmentation using partition walls. By dividing the discharge cell into multiple stacked spaces, the system increases discharge surface area in the vertical dimension, maintaining a compact apparatus volume while enhancing ozone generation capacity.
Solution Approach 2:
Multiple discharge spaces are nested vertically within a single cell structure, with partition walls creating stacked discharge surfaces. This nested arrangement maximizes the discharge surface area within a limited volume, effectively increasing ozone generation amount without proportionally increasing the apparatus volume.
