Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If electromagnetic radiation is used to transmit data for device authentication, then security is improved, but device complexity increases
Solution Approach 1:
The patent uses electromagnetic radiation as an intermediary medium to transmit authentication data between devices. The light communication module generates electromagnetic radiation that carries encoded authentication information, serving as a secure intermediary channel that avoids traditional wireless communication vulnerabilities while maintaining system functionality
Solution Approach 2:
The apparatus integrates multiple functions into a single system: the light communication module both generates electromagnetic radiation for data transmission and captures biometric features for authentication. This multi-functionality reduces the need for separate dedicated components, thereby limiting the increase in device complexity while enhancing security
2Measurement precision
If biometric features are captured using electromagnetic radiation, then authentication accuracy is improved, but energy consumption increases
Solution Approach 1:
The light communication module employs periodic modulation of electromagnetic radiation to capture biometric features. By using time-based modulation patterns, the system can accumulate sufficient signal data over multiple cycles, improving measurement precision while distributing energy consumption over time rather than requiring high instantaneous power
Solution Approach 2:
The system changes parameters of the electromagnetic radiation, such as wavelength and intensity, to optimize biometric feature capture. By adjusting these parameters based on detection needs, the system achieves high authentication accuracy while minimizing energy consumption through efficient use of the electromagnetic spectrum
