Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional identification devices use specialized electronic components or biometric scanning, then authentication reliability is improved, but device complexity and cost increase
Solution Approach 1:
The patent replaces complex electronic authentication systems with a simplified electromagnetic sensing system. Instead of using specialized electronic components or biometric scanners, the system uses an antenna to sense electrical characteristics (such as capacitance or inductance) of items coupled with a person's body. The controller then compares these sensed characteristics against stored profiles to authenticate the person, thereby reducing device complexity while maintaining authentication reliability.
2Reliability
If conventional identification devices include specialized hardware components, then authentication capability is improved, but device size increases
Solution Approach 1:
The patent makes the sensing system universal by enabling it to authenticate individuals using any item they are coupled with (such as jewelry, clothing, or accessories) rather than requiring specialized wearable authentication devices. The antenna senses electrical characteristics that are inherent to the combination of the person's body and their personal items, eliminating the need for dedicated authentication hardware and reducing device size.
3Measurement precision
If conventional identification devices use complex biometric scanning procedures, then authentication accuracy is improved, but ease of operation deteriorates
Solution Approach 1:
The patent implements self-service authentication by having the system automatically sense and compare electrical characteristics without requiring the user to perform complex biometric scanning procedures. The user simply needs to be in proximity to or coupled with the sensing device with their personal item, and the controller automatically completes the authentication process by comparing sensed characteristics against stored profiles, thereby maintaining accuracy while greatly improving ease of operation.
