Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional ozone sources are used, then disinfection function is provided, but permeability is low and attachment to electronic apparatus is difficult
Solution Approach 1:
The patent combines the ozone generation function with the display device by integrating transparent electrodes directly into the display structure. The electrode substrate that forms part of the display medium also serves as the ozone generation element, eliminating the need for separate disinfection devices and improving attachment ease while maintaining disinfection reliability.
Solution Approach 2:
The transparent electrode substrate serves dual purposes: it functions as both the display medium component and the ozone generation element. This multi-functionality allows the same structure to provide both display and disinfection capabilities, resolving the contradiction between maintaining reliable disinfection and improving ease of attachment.
2Reliability
If conventional ozone sources are used, then disinfection function is provided, but separate disinfection devices are required
Solution Approach 1:
The patent merges the ozone generation function with the display device structure by incorporating transparent electrodes into the display medium. This integration eliminates the need for separate disinfection devices, reducing device complexity while maintaining the reliability of the disinfection function.
Solution Approach 2:
The electrode substrate is designed to serve multiple functions: it acts as both the display medium and the ozone generation element. This multi-functionality reduces the overall device complexity by eliminating redundant components while ensuring the disinfection function remains reliable.
3Productivity
If metal electrodes are used in ozone sources, then ozone generation is effective, but permeability is reduced
Solution Approach 1:
The patent changes the material parameter of the electrodes from opaque metal to transparent conducting materials. This parameter change maintains the electrical conductivity needed for effective ozone generation while improving light permeability, allowing the electrodes to function effectively in transparent display applications.
Solution Approach 2:
The patent uses transparent conducting materials that combine the properties of metal electrodes (electrical conductivity for ozone generation) with optical transparency. This composite material approach maintains ozone generation efficiency while improving permeability for display applications.

Implementation Method 1
the discharge start voltage on that surface side of the insulating substrate which faces the electrode is lower than the discharge starting voltage on that surface side of the insulating film which faces the electrode... when an AC high voltage applied from an external power source is gradually increased, a discharge is started on the surface of the insulating substrate side, and plasma is generated. By this plasma, oxygen in the air is decomposed and bonded to generate ozone
Implementation Method 2
a discharge is started on the surface of the insulating substrate side, and plasma is generated. By this plasma, oxygen in the air is decomposed and bonded to generate ozone
