Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a secure element implements multiple operating systems to support various digital services, then the functionality and versatility of the device is improved, but the device complexity and difficulty of managing cohabitation between systems increases
Solution Approach 1:
The patent segments the communication interface by implementing separate physical interfaces for each operating system (first physical interface for first OS, second physical interface for second OS). This segmentation allows each OS to communicate independently without interference, reducing the complexity of managing multiple OS cohabitation while maintaining versatility.
Solution Approach 2:
The patent introduces a routing circuit as an intermediary component that manages data flow between multiple operating systems and external devices. This mediator handles the complexity of OS cohabitation by routing communications appropriately, allowing the secure element to support multiple digital services without increasing overall system complexity.
2Ease of operation
If separate physical interfaces are provided for each operating system, then the ease of operation and independence of each system is improved, but the number of components and device complexity increases
Solution Approach 1:
The patent applies local quality by providing specific communication interfaces tailored to each operating system's needs. The first operating system uses a first physical interface optimized for its requirements, while the second operating system uses a second physical interface suited to its demands. This localized optimization improves ease of operation for each system without requiring a complete redesign of the entire communication architecture.
