Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems in electronic devices often struggle to efficiently communicate with and power memory cards that are deactivated, limiting the user's access to stored data and services.
Innovation Solution
A communication circuit chip and electronic device configuration that includes a power manager to transfer power to selected memory cards based on reception signals, and a controller to select and communicate with memory cards, even if they are initially deactivated, using a third communication circuit to enable data transfer.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If a communication circuit is deactivated to save power, then power consumption is reduced, but the ability to communicate with and access data from the memory card is lost
Solution Approach 1:
The system performs preliminary actions by storing metadata about memory card contents in the active communication circuit before deactivation. When a deactivated memory card is needed, the system retrieves this pre-stored metadata to identify and access the required data without needing to fully activate the communication circuit, thus maintaining data accessibility while saving power.
Solution Approach 2:
The patent introduces an intermediary mechanism where the active communication circuit maintains metadata about deactivated memory cards. This metadata acts as an intermediary that allows the system to locate and access data on deactivated memory cards without requiring the deactivated communication circuit to be fully operational, bridging the gap between power savings and data access needs.
2Adaptability or versatility
If multiple communication circuits are maintained active to access multiple memory cards, then data accessibility is improved, but power consumption increases
Solution Approach 1:
The system segments communication functionality by maintaining only the necessary metadata in active circuits while allowing individual memory cards to be activated on-demand. This segmentation allows the system to support multiple memory cards without keeping all communication circuits continuously active, reducing overall power consumption while maintaining accessibility.
Solution Approach 2:
The patent changes the operational parameters of communication circuits by transitioning them between active and deactivated states based on actual access needs. Rather than maintaining all circuits in a high-power active state, the system dynamically adjusts their operational state, using metadata to enable quick reactivation or targeted access when needed.
Data Source
AI summary
A communication circuit chip includes a controller, a power manager, and a memory. The controller selectively communicates, based on a reception signal that is received through an antenna, with one memory card among first and second memory cards. The power manager transfers power, in response to receiving the reception signal through the antenna, to the one memory card that is selected to communicate with the controller. The memory stores content data such that content of data stored in each of the first and second memory cards is recognized. The controller selects the one memory card that is to communicate with the controller from among the first and second memory cards, with reference to the stored content data.
