Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If contact smart cards are used with rigid physical connections, then data exchange reliability is ensured, but flexibility and adaptability between different services and terminal units deteriorate
Solution Approach 1:
The patent replaces the mechanical contact-based communication system with a wireless communication system. The smart card communicates with the terminal unit through wireless signals instead of physical contact, eliminating the need for rigid physical connections while maintaining data exchange reliability. This substitution enables the smart card to be used across multiple services and terminal units without physical reconfiguration.
Solution Approach 2:
The patent implements a universal smart card design that can be applied across multiple services and terminal units. By removing service-specific physical constraints and protocol bindings, the smart card becomes a multi-functional device that can adapt to different applications through software configuration rather than hardware reconfiguration.
2Reliability
If smart cards are bound to specific application protocols, then service functionality is ensured, but ease of operation and user convenience deteriorate
Solution Approach 1:
The patent introduces dynamic protocol selection capability where the smart card can automatically adapt to different application protocols based on the service context. Instead of being statically bound to a single protocol, the card dynamically configures its communication parameters to match the required service, making the system more adaptable and easier to operate across diverse applications.
Solution Approach 2:
The patent introduces an intermediary layer (wireless communication module and control software) that translates between different application protocols and the smart card's core functions. This intermediary enables seamless protocol switching without requiring user intervention or manual reconfiguration, thereby improving ease of operation while maintaining service functionality.
3Adaptability or versatility
If multiple smart cards are used for different services, then service coverage is ensured, but device complexity and loss of substance increase
Solution Approach 1:
The patent creates a universal smart card that can perform multiple service functions through software configuration rather than requiring separate physical cards for each service. The single card contains the capability to adapt to different terminal units and services, eliminating the need for users to carry multiple service-specific cards and reducing overall system complexity.
Solution Approach 2:
The patent merges multiple service functionalities into a single smart card device. By integrating wireless communication capabilities and multiple protocol support into one card, the system consolidates what would have been separate cards into a unified device, reducing the number of components users need to manage and decreasing the risk of loss.
4Manufacturing precision
If physical contact connections are required, then manufacturing precision and contact reliability are ensured, but ease of operation and adaptability deteriorate
Solution Approach 1:
The patent replaces the mechanical contact connection system with a wireless communication system. This substitution eliminates the need for precise physical alignment and contact reliability concerns, as wireless communication does not require physical contact between components. The smart card can be used with any terminal unit within wireless range, significantly improving adaptability and flexibility.
