Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If vascular pattern recognition system is integrated on portable card, then security is enhanced, but device complexity increases
Solution Approach 1:
The patent combines multiple functional components (NIR light source, image sensor array, processing circuits, and communication interfaces) into a single integrated vascular pattern recognition system on a portable card. This merging approach enhances security by incorporating biometric authentication while managing device complexity through systematic integration of all necessary components on one platform.
Solution Approach 2:
The portable card system performs multiple functions: vascular pattern detection, image processing, authentication verification, and wireless communication via NFC. This multi-functionality allows the card to provide enhanced security through biometric recognition while also maintaining standard payment card capabilities, thereby addressing both security enhancement and device complexity considerations.
2Reliability
If vascular pattern recognition system is integrated on portable card, then authentication security is improved, but card thickness increases
Solution Approach 1:
The patent employs flexible hybrid electronics and thin-film technology to integrate the vascular pattern recognition system components on a portable card with thickness of approximately 2mm or less. This approach allows authentication security to be improved through biometric capabilities while maintaining the card's portability and thin profile suitable for credit card applications.
3Length of stationary object
If flexible hybrid electronics and photonics technology are used, then card thickness is reduced, but manufacturing complexity increases
Solution Approach 1:
The patent utilizes flexible hybrid electronics combining organic and inorganic materials, along with photonics technology, to create a thin-card structure. This composite material approach reduces card thickness to approximately 2mm or less while managing manufacturing complexity through the systematic integration of compatible materials and processes suitable for credit card fabrication.

Implementation Method 1
The light source 152 should emit in the NIR, within a wavelength range of approximately 800 nm to 1000 nm. At these wavelengths, the light is transmitted through human tissue, ie, the skin, but is absorbed and scattered by the blood in the blood vessels.
Implementation Method 2
At these wavelengths, the light is transmitted through human tissue, ie, the skin, but is absorbed and scattered by the blood in the blood vessels.
Implementation Method 3

Data Source
AI summary
In the examples provided herein, a vascular pattern recognition system integrated onto a portable card includes a vascular pattern detection system to obtain image data of blood vessels of a finger to be swiped across a detection area on the portable card, wherein the vascular pattern detection system includes a near infrared light source and an image sensor array. The vascular pattern recognition system also includes an image processor to process the image data to generate a scanned vascular pattern and compare the scanned vascular pattern to a pre-stored pattern stored on the portable card to authenticate the image data, and a security processor to generate a transaction code to authorize a transaction upon authentication of the image data.
