Engineering Contradiction Analysis
1Volume of moving object
If the size of electronic device is decreased, then integration density is improved, but electrical signal interference increases due to strong interaction between electrons
Solution Approach 1:
The patent replaces electrical signal transmission with optical signal transmission using photoelectric signals. By using light instead of electrical signals, the harmful electron interactions are eliminated while maintaining information transmission capabilities, thus resolving the signal interference problem in miniaturized devices.
Solution Approach 2:
The patent changes the transmission medium from electrical domain to optical domain by introducing photoelectric signals. This parameter change allows the device to operate without electron interactions while maintaining compact size, as light signals do not suffer from the same interference issues as electrical signals in close proximity.
2Object-affected harmful factors
If light is used for information processing, then signal interference is reduced, but device structure must be changed to accommodate optical components
Solution Approach 1:
The patent makes the existing electronic device structure multi-functional by enabling it to respond to both electrical stimuli and light irradiation. The same device structure can perform electrical signal processing and optical signal processing, eliminating the need for separate optical components and maintaining structural simplicity.
Solution Approach 2:
The patent enables the electronic device to utilize its existing structure for optical signal processing without requiring additional external optical components. The device structure itself serves the dual purpose of electrical and optical signal handling, making the system self-sufficient and avoiding increased complexity.
3Device complexity
If conventional electronic information transmission is used, then device structure is maintained, but light incident angle selectivity and high-speed processing are not achieved
Solution Approach 1:
The patent introduces dynamic control of light transmission through incident angle selectivity. By controlling the angle at which light enters the device, the information processing capability can be dynamically adjusted, enabling high-speed processing while maintaining the existing device structure. This dynamic control mechanism allows the device to switch between different operational modes without physical reconfiguration.

AI summary
Disclosed herein is a method of changing characteristics of an electronic device, including the steps of: applying light to an electronic device through a plurality of media having different refractive indexes from each other, the electrical characteristics of the electronic device being changed depending on the amount of incident light; and changing an incident angle of light applied the electronic device to adjust the amount of incident light. There is provided a method of providing light incident angle dependency by a simple procedure of accumulating additional media in various electronic devices. In the method, the light incident angle selectivity of the electronic device can be maintained even when the inclination angle of the device is changed depending on the axis parallel to the incident direction of light even though the incident direction thereof is fixed. This means that the performance of the device can be controlled only by changing the inclination angle of the device without greatly changing the dynamic state of the device. Further, since the movement speed of photons is higher than that of electrons and the signal interference of photons is lower than that of electrons, an additional effect of increasing the operating speed of the device or decreasing the size of the device can be expected.
