Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual detection is used for non-electrically conductive attack materials, then the security of biometric recognition device can be detected, but high consumption of human resources and long test period occur
Solution Approach 1:
The patent changes the electrical conductivity parameter of the attack material by adding conductive components (conductive tape, conductive paint, or conductive fabric) to traditionally non-conductive materials like paper or transparent film. This parameter change enables the materials to be detected by automatic detection devices while maintaining their effectiveness as attack materials, thereby resolving the contradiction between reliable security detection and test efficiency.
2Reliability
If manual detection is used for biometric feature attack materials, then the security testing can be performed, but large operation error occurs
Solution Approach 1:
The patent replaces the manual mechanical detection process with an automatic detection system. The automatic detection device uses the conductive properties of the modified attack materials to automatically identify and test them, eliminating human operational errors and improving measurement precision while maintaining reliable security testing capability.
3Ease of manufacture
If non-electrically conductive materials are used for attack, then the attack material can be simple and effective, but automatic detection becomes difficult
Solution Approach 1:
The patent creates composite attack materials by combining traditionally simple non-conductive materials (paper, transparent film) with conductive components (conductive tape, conductive paint, or conductive fabric). This composite structure maintains the simplicity and effectiveness of the original attack materials while adding detectable conductive properties, enabling automatic detection without complicating the manufacturing process.
