Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a biometric identification system uses only fingerprint recognition, then the operation is simple and fast, but the security level is insufficient for accessing multiple accounts in public settings
Solution Approach 1:
The patent combines fingerprint recognition with finger stroke sequence recognition into a unified authentication system. The fingerprint scanner captures both the static fingerprint pattern and the dynamic finger stroke sequence, merging two authentication methods into a single device operation. This combination resolves the contradiction by providing enhanced security through multiple authentication factors while maintaining a relatively simple user interface where the user only needs to place their finger on the scanner.
Solution Approach 2:
The fingerprint scanner is designed to perform multiple functions: capturing static fingerprint patterns for identification and capturing dynamic finger stroke sequences for additional authentication. This multi-functionality allows the same hardware component to support both authentication methods, resolving the contradiction between security enhancement and device complexity by making the authentication system versatile without requiring separate dedicated devices for each method.
2Ease of operation
If the fingerprint roller is exposed for easy access, then the ease of operation is improved, but the device is vulnerable to observation by onlookers in public settings
Solution Approach 1:
The fingerprint roller is nested within the housing structure, with only a portion accessible through a slot in the scanning end. The housing cavity contains the fingerprint roller, and the palm rest extends into the cavity to form a concave indentation that guides finger placement. This nested arrangement allows the fingerprint roller to be protected within the housing while still being accessible through the slot, resolving the contradiction between ease of operation and protection from observation.
Solution Approach 2:
The slot in the scanning end acts as an intermediary element between the user's finger and the fingerprint roller. It allows the finger to contact the fingerprint roller for scanning while limiting the exposure of the roller to external observation. The slot serves as a controlled interface that enables functionality while providing privacy protection in public settings.
3Productivity
If the fingerprint roller is used repeatedly without cleaning, then the productivity is maintained, but the accumulation of fingerprints degrades measurement precision and security
Solution Approach 1:
The system incorporates an automatic cleaning mechanism that cleans the fingerprint roller without requiring manual intervention. The cleaning system is integrated into the device and operates autonomously to remove accumulated fingerprints from the roller surface, allowing the device to maintain high measurement precision throughout continuous operation without sacrificing productivity.
4Measurement precision
If a cleaning system is integrated into the device, then the measurement precision is maintained over time, but the device complexity increases
Solution Approach 1:
The cleaning system is merged with the existing housing structure and fingerprint roller assembly. The cleaning components are integrated into the cavity where the fingerprint roller is located, combining the cleaning function with the existing scanning mechanism. This integration resolves the contradiction by maintaining measurement precision through automated cleaning while minimizing the increase in overall device complexity through shared structural elements.
