Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If security hardware is added to endpoint devices for multi-factor authentication, then authentication security is improved, but device cost and complexity increase
Solution Approach 1:
The patent makes existing wireless communication interfaces (Wi-Fi, Bluetooth) perform dual functions: both their original communication purposes and biometric authentication. The wireless interface transmits both data packets and sensing signals, eliminating the need for separate dedicated security hardware while maintaining authentication security.
Solution Approach 2:
The patent enables existing wireless sensors to serve authentication purposes without requiring additional specialized hardware. The wireless communication components already present in endpoint devices are repurposed to perform biometric sensing, allowing the device to authenticate users using its own existing infrastructure.
2Measurement precision
If dedicated security hardware is used for biometric authentication, then authentication accuracy is improved, but ease of operation deteriorates due to orientation requirements
Solution Approach 1:
The patent utilizes existing wireless communication interfaces to perform both communication and biometric sensing functions. This eliminates the need for dedicated biometric sensors with specific orientation requirements, as the wireless interface can detect users from various positions while maintaining authentication accuracy.
3Reliability
If additional security hardware is added to endpoint devices, then authentication capability is improved, but manufacturing cost increases
Solution Approach 1:
The patent enables existing wireless communication components to perform dual purposes: standard communication and biometric authentication. This eliminates the need to manufacture devices with separate dedicated security hardware, reducing component count and manufacturing costs while maintaining authentication capability.
Solution Approach 2:
The patent merges the authentication function with existing wireless communication functions. By combining these functions into a single integrated approach using existing hardware, the patent reduces the total number of components needed, simplifying manufacturing and reducing costs.
