Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If fingerprint identification is used for device unlocking, then ease of operation is improved, but security is worsened due to vulnerability to decryption schemes

Engineering Contradiction:
Improveease of operationVSAvoidsecurity
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The patent combines fingerprint recognition with pulse wave recognition into a unified biometric authentication system. The fingerprint receiving module captures fingerprint patterns while the pulse receiving module detects pulse wave information through optical sensors. Both biometric factors must be verified simultaneously to unlock the device, creating a merged authentication mechanism that maintains ease of operation while significantly enhancing security against decryption attacks.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The authentication system uses composite biometric verification by integrating two different biometric modalities (fingerprint and pulse wave) into a single authentication framework. This composite approach ensures that even if one biometric factor is compromised through decryption schemes, the other factor remains protected, thereby maintaining overall system security while preserving user convenience.

Inventive Principle:
Principle #40Composite materials

2Reliability

If dual biometric authentication is implemented, then security is improved, but device complexity is worsened

Engineering Contradiction:
ImprovesecurityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The biometric authentication device integrates multiple functions into a single system: the fingerprint receiving module handles fingerprint pattern capture, while the pulse receiving module with infrared light emitting diodes and optical identification modules handles pulse wave detection. Both modules operate within the same authentication framework, allowing the device to perform multiple biometric verification functions without requiring separate independent systems, thereby limiting the increase in device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent merges the fingerprint authentication system and pulse wave authentication system into a single integrated biometric verification apparatus. By combining these two authentication mechanisms in one device with unified processing logic, the system achieves enhanced security without proportionally increasing overall device complexity, as both functions share common processing resources and integration architecture.

Inventive Principle:
Principle #5Merging (Combining)
