Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If data is transmitted on a wireless channel, then communication speed and convenience are improved, but security is worsened due to vulnerability to fraudulent receipt and brute force attacks
Solution Approach 1:
The patent replaces traditional electronic data transmission with optical radiation transmission. The encoding element modulates optical properties (transmission, reflection, absorption) to encode data, substituting electromagnetic field-based electronic communication with photon-based optical communication, thereby enhancing security against conventional electronic eavesdropping and attacks
Solution Approach 2:
The patent changes the fundamental parameter of data encoding from electronic signals to optical radiation properties. The encoding element varies optical parameters (transmission coefficient, reflection coefficient, absorption coefficient) to represent data, making the communication medium inherently more secure as optical signals are harder to intercept and decode without proper authorization
2Quantity of substance
If ciphered data is stored in conventional storage devices, then data storage capability is improved, but reliability is worsened due to susceptibility to environmental damage and corruption
Solution Approach 1:
The patent utilizes phase transition of optical properties in the encoding element. By locally altering the optical phase characteristics (transmission, reflection, absorption states) of different areas in the encoding element, data is stored in a physically stable manner that resists environmental degradation, unlike conventional electronic storage media
Solution Approach 2:
The encoding element functions as a composite optical structure with areas having different optical properties. This composite nature, with regions of varying transmission, reflection, and absorption characteristics, creates a robust storage medium that maintains data integrity under adverse environmental conditions such as temperature variations, humidity, and electromagnetic interference
3Reliability
If conventional ciphering algorithms are used, then encryption capability is improved, but vulnerability is worsened when partial memory corruption occurs, jeopardizing the entire ciphered message
Solution Approach 1:
The patent segments the encoded data across multiple spatially distributed areas of the encoding element. Each area stores a portion of the ciphered message or key information independently. This segmentation means that partial corruption or damage to one area does not compromise the entire data set, as the remaining intact areas preserve other portions of the information
