Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electrode is formed by vapor deposition on the dielectric tube, then the electrode is firmly attached to the dielectric tube, but the electrode cannot be separated for replacement and manufacturing complexity increases
Solution Approach 1:
The electrode is segmented into multiple independent wire elements that can be individually inserted through the dielectric tube. Each wire can be independently replaced without affecting the entire electrode structure or dielectric tube, resolving the contradiction between firm attachment and replaceability.
Solution Approach 2:
The electrode wires are extracted from the traditional vapor-deposited integrated structure and made as separate removable components. This allows the electrode to be taken out and replaced independently from the dielectric tube, maintaining reliability during operation while enabling easy replacement when needed.
2Stability of the object's composition
If the electrode is formed by vapor deposition, then the electrode structure is integrated, but manufacturing steps increase and productivity decreases
Solution Approach 1:
The electrode manufacturing process is segmented into independent steps: preparing individual wire elements, inserting them through the dielectric tube, and connecting them to terminals. This modular approach simplifies each manufacturing step and enables parallel production, significantly improving productivity compared to complex vapor deposition processes.
Solution Approach 2:
The wire elements naturally form the electrode structure through their own elastic deformation and self-arrangement within the dielectric tube, eliminating the need for complex external manufacturing processes like vapor deposition. This self-organizing property simplifies manufacturing and enhances productivity.
3Duration of action of stationary object
If the electrode is made of corrosion-resistant material, then the electrode durability increases, but the cost of materials increases
Solution Approach 1:
The corrosion resistance function is extracted from the electrode material itself and transferred to the dielectric tube that surrounds and protects the electrode wires. This allows the use of less expensive electrode materials while maintaining long service life through the protective dielectric barrier.
Solution Approach 2:
The dielectric tube acts as an intermediary protective layer between the electrode wires and the corrosive environment. This mediator protects the electrode from corrosion, enabling the use of lower-cost electrode materials while maintaining durability and extending service life.
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
Facilitates easy electrode replacement and enhances productivity by allowing for the use of less expensive, non-corrosion-resistant materials and reducing the need for frequent replacements, especially in large-scale units.
Implementation Method 1
When a high voltage is applied between the two electrodes, a silent discharge occurs in the discharge gap. Ozone is generated by causing a source gas containing oxygen to flow into the discharge gap, where the source gas is ozonized.
