SIM SD Card Tray Priority Detection Power Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices with multiple SIM and SD cards face issues with unnecessary resets due to security duplication when multiple memory cards are inserted, leading to inefficiencies in power consumption and task processing.
Innovation Solution
An electronic device with a housing, tray, and sockets that detect the insertion and extraction of SIM and SD cards, determining their priority and selectively resetting the task block for the SIM card if it has a higher priority, thereby reducing unnecessary resets and optimizing power usage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device resets the task block for SIM card authentication when multiple memory cards are inserted, then security against duplication is improved, but unnecessary resets occur for SD cards leading to increased power consumption and reduced processing efficiency
Solution Approach 1:
The patent applies local quality by differentiating the reset operation between different card types. The processor identifies whether the inserted card is a SIM card or SD card and selectively resets only the task block for SIM card authentication, while leaving the SD card task block unchanged. This targeted approach maintains security for SIM cards while avoiding unnecessary resets for SD cards, thereby reducing power consumption and improving processing efficiency.
2Reliability
If the electronic device resets the task block for SIM card authentication when multiple memory cards are inserted, then security against duplication is improved, but processing efficiency deteriorates due to unnecessary resets
Solution Approach 1:
The patent applies local quality by differentiating the reset operation between different card types. The processor identifies whether the inserted card is a SIM card or SD card and selectively resets only the task block for SIM card authentication, while leaving the SD card task block unchanged. This targeted approach maintains security for SIM cards while avoiding unnecessary resets for SD cards, thereby reducing power consumption and improving processing efficiency.
3Area of stationary object
If the electronic device inserts multiple SIM cards and SD cards into one socket using a tray, then space utilization is improved, but card management complexity increases due to different reset requirements
Solution Approach 1:
The patent applies parameter changes by modifying the reset operation parameter based on the card type detected. When a SIM card is detected, the processor resets the task block; when an SD card is detected, the processor does not reset the task block. This dynamic parameter adjustment simplifies card management by providing clear, differentiated handling rules for different card types, reducing the complexity of managing multiple cards in a single socket.

AI summary
An electronic device is provided which includes a housing having a hole, a tray that receives a subscriber identification module (SIM) card and a secure digital (SD) card, a first socket, a communication circuit, a processor, and a battery that supplies power to the communication circuit, the processor, the SIM card, and the SD card, wherein the processor is configured to detect extraction of the tray from the first socket, interrupt power supply to the SIM card and the SD card through the first socket in response to extraction of the tray, detect insertion of the tray into the first socket, determine a priority of the SD card and the SIM card when both the SIM card and the SD card are detected in the inserted tray, and reset a task block that processes the SIM card, if the SIM card has a higher priority than the SD card.
