Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If fingerprint recognition is used for biometric identification, then user identification can be performed, but geometrical deformation and low reproducibility reduce reliability
Solution Approach 1:
The patent combines multiple biometric identification methods (fingerprint recognition, iris recognition, face recognition, and voice recognition) into a unified security system. By merging these different biometric technologies, the system overcomes the individual limitations of each method and achieves higher overall reliability and precision in user identification.
2Reliability
If iris recognition is used for biometric identification, then recognition error rate is low, but precise focal distance requirement and difficulty with movement reduce ease of operation
Solution Approach 1:
The patent integrates iris recognition with other biometric methods (fingerprint, face, voice) in a combined security system. This merging allows the system to maintain the high accuracy of iris recognition while compensating for its operational difficulties through alternative biometric channels, thereby improving overall ease of operation.
3Reliability
If retina scanning is used for biometric identification, then individual pattern recognition is accurate, but light irradiation risk and eye contamination reduce safety
Solution Approach 1:
The patent combines retina scanning with other non-contact or less invasive biometric methods (fingerprint, face, voice recognition) in a unified security system. By merging these methods, the system maintains accurate individual pattern recognition while reducing reliance on retina scanning alone, thereby minimizing eye contamination risks.
4Ease of operation
If face recognition is used for biometric identification, then non-contact identification is achieved, but shape variation due to angle, expression, or age reduces measurement precision
Solution Approach 1:
The patent integrates face recognition with other biometric methods (fingerprint, iris, voice) in a combined security system. By merging these different biometric technologies, the system maintains the non-contact convenience of face recognition while compensating for its precision issues through complementary identification methods, achieving more reliable overall identification.
5Ease of operation
If voice identification is used for biometric identification, then user identification is simple, but voice fabrication and noise obstructions reduce reliability
Solution Approach 1:
The patent combines voice identification with other biometric methods (fingerprint, iris, face recognition) in a unified security system. By merging these methods, the system maintains the simplicity of voice identification while compensating for its security vulnerabilities through additional biometric verification layers, thereby achieving both ease of operation and high reliability.
