Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional smart cards cannot dynamically adjust communication speed during data transmission, which can lead to reduced communication quality due to noise interference, especially in ultra-high-speed communication scenarios.
Innovation Solution
A smart card system that includes a communication section and a control section, allowing for the initial setup of a communication speed and subsequent dynamic adjustment to a higher speed upon request from an external device, with error checking mechanisms to maintain data integrity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If ultra-high speed communication is used to transmit large amount of data, then communication time is shortened, but communication quality is reduced due to noise interference
Solution Approach 1:
The patent implements dynamic communication speed adjustment by allowing the portable electronic device to switch between multiple communication speeds during data transmission. The control section monitors communication quality and adjusts the speed accordingly, enabling the system to operate at ultra-high speeds when conditions are favorable and reduce to lower speeds when noise interference is detected, thus resolving the contradiction between speed and reliability
Solution Approach 2:
The patent changes the communication speed parameter dynamically during operation. The system establishes an initial communication speed, then adjusts this parameter based on communication quality feedback, error rates, and noise conditions. This parameter adaptation allows the system to optimize both transmission speed and communication quality under varying conditions
2Stability of the object's composition
If communication speed is established in initial response process, then communication stability is maintained, but communication speed cannot be changed during communication procedure
Solution Approach 1:
The patent transforms the static communication speed establishment into a dynamic process. While maintaining protocol stability through structured speed change procedures, the system enables multiple speed transitions during communication procedures. The control section manages speed changes with proper protocol handling, achieving both stability and adaptability
Solution Approach 2:
The communication system is designed to handle multiple functions: initial speed establishment, ongoing speed adjustments, error monitoring, and quality assessment. This multi-functionality allows the same communication infrastructure to maintain stability while adapting speed to various communication conditions and requirements

AI summary
According to an embodiment, a smart card includes a communication section and a control section. The communication section communicates with the external device. The control section sets up a first speed as the communication speed used for communication with the external device by the communication section. Moreover, the control section changes the communication speed from the first speed set up to a second speed specified by a change request when the control section receives the change request of the communication speed from the external device by the communication section.
