Communication Processor Frequency Switching for Timed Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Communication apparatuses face challenges in completing authentication processing within a predetermined time when shifting from a normal power mode to a power saving mode, leading to potential failure, while always maintaining normal power mode results in increased power consumption.
Innovation Solution
The communication apparatus dynamically switches its power state based on the connection to an external apparatus requiring authentication, allowing it to adjust its power mode and operating frequency to ensure successful authentication without excessive power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the communication apparatus shifts from normal power mode to power saving mode, then power consumption is reduced, but authentication processing cannot be completed within the predetermined time
Solution Approach 1:
The communication apparatus dynamically adjusts its power mode based on the authentication state. When authentication is required, the system transitions from power saving mode to normal power mode to ensure authentication completes within the predetermined time. This dynamic switching resolves the contradiction by adapting the power consumption level to the specific operational requirements at each moment.
Solution Approach 2:
The system changes the operating parameters (power mode) based on the authentication state. By detecting when authentication is required and switching to normal power mode, the system ensures that processing speed and power consumption are optimized for the current task, preventing authentication timeout while managing overall power usage efficiently.
2Reliability
If the communication apparatus always maintains normal power mode, then authentication processing can be completed successfully, but power consumption increases
Solution Approach 1:
The communication apparatus periodically checks the authentication state and transitions between power modes accordingly. Instead of maintaining normal power mode continuously, the system switches to power saving mode when authentication is not required, and only activates normal power mode when authentication is detected as necessary, thus reducing overall power consumption while ensuring authentication success when needed.
Solution Approach 2:
The system automatically detects authentication requirements and manages its own power state transitions without external intervention. By monitoring the authentication state and self-adjusting the power mode, the communication apparatus ensures authentication reliability when needed while minimizing power consumption during normal operation.
