Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods are used in wearable devices, then device complexity is reduced, but security level deteriorates
Solution Approach 1:
The patent combines display elements and light-receiving elements into a single pixel portion, merging authentication functionality with the display structure. This integration allows fingerprint authentication without adding separate authentication hardware, thereby improving security while maintaining simplicity.
Solution Approach 2:
The pixel portion serves multiple functions: it acts as both a display element and a light-receiving element for authentication. This multi-functionality reduces the need for separate components, achieving high security levels without significantly increasing device complexity.
2Adaptability or versatility
If multiple authentication functions are added to wearable devices, then versatility is improved, but device complexity increases
Solution Approach 1:
The pixel portion is designed to perform multiple functions including display, light reception for authentication, and attachment detection. This universal design enables the device to provide various authentication methods (fingerprint, palm print) and wearable detection without proportionally increasing complexity.
Solution Approach 2:
Multiple authentication-related components (display elements, light-receiving elements, sensors) are merged into integrated pixel portions and sensor portions, allowing the device to achieve multifunctionality while keeping the overall structure compact and manageable.
3Reliability
If fingerprint authentication is implemented, then security level is improved, but ease of operation deteriorates
Solution Approach 1:
The authentication function is merged with the display surface, allowing users to authenticate by simply touching the display area. This integration eliminates the need for separate authentication buttons or sensors, maintaining ease of operation while providing high security.
