Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If traditional magnetic stripe or EMV processors are used in transaction cards, then basic transaction functionality is achieved, but display capabilities and sensor integration remain limited due to the small card size
Solution Approach 1:
The patent combines multiple functions into a single component by using LED display components that can both display information and detect light as photosensors. This dual-functionality approach allows the system to achieve enhanced display capabilities and sensor integration without increasing the physical card size, as the same physical space serves multiple purposes.
Solution Approach 2:
The LED display components are designed to perform multiple functions: they can display visual information to the user and simultaneously act as photosensors to detect light conditions for activation. This multi-functionality principle allows the transaction card to incorporate advanced features while maintaining its standard size constraints.
2Difficulty of detecting and measuring
If LED display components are used as photosensors to detect light and activate the card, then activation detection capability is improved, but device complexity increases
Solution Approach 1:
The LED display components serve dual purposes: displaying information and detecting light for activation. By making these components universal rather than specialized, the patent reduces the need for separate dedicated photosensor components, thereby managing device complexity while improving detection capability.
Solution Approach 2:
The LED display components are self-sufficient in that they can perform both their display function and sensing function without requiring additional dedicated components. This self-service approach simplifies the overall system architecture by eliminating the need for separate activation detection hardware.
3Reliability
If dynamic transaction cards with advanced features are implemented, then user interaction and security are improved, but manufacturing complexity and cost increase
Solution Approach 1:
The patent merges the display and sensing functions into a single component, which simplifies the manufacturing process compared to integrating multiple separate components. This consolidation approach reduces assembly steps and potential failure points, thereby improving ease of manufacture while maintaining enhanced security and user interaction features.
Solution Approach 2:
By designing LED components that perform multiple functions, the patent reduces the total component count and simplifies the bill of materials, which directly impacts manufacturing complexity and cost. The multi-functional design allows advanced features to be implemented without proportionally increasing manufacturing difficulty.
