Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic devices face high current consumption issues due to continuous connection maintenance and periodic notification requirements, particularly with application processors that perform various functions, leading to increased power usage.
Innovation Solution
An electronic device and method that utilize a communication processor to collect events associated with application operations while the application processor is in a sleep state, allowing the communication processor to transmit messages to external devices, thereby reducing current consumption by minimizing the need for high-power application processor involvement in periodic scheduling event processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the application processor maintains continuous connections and performs periodic notifications to ensure reliable operation, then connection reliability is improved, but current consumption increases
Solution Approach 1:
The patent divides the processing functions into two separate processors: the application processor handles user applications while the communication processor handles connection maintenance and periodic notifications. This segmentation allows the application processor to enter sleep state more frequently, reducing overall current consumption while maintaining connection reliability through the dedicated communication processor.
Solution Approach 2:
The communication processor acts as an intermediary between the application processor and the external server/base station. It collects events from the application processor and transmits notifications independently, enabling the application processor to remain in sleep state while still maintaining reliable connections and performing periodic notifications.
2Adaptability or versatility
If the application processor performs all functions including periodic scheduling events, then functional completeness is improved, but current consumption increases
Solution Approach 1:
The patent segments functional responsibilities by implementing a communication processor that specifically handles periodic scheduling events and connection maintenance. This allows the application processor to focus on user applications and enter sleep state more efficiently, reducing current consumption while maintaining functional completeness through the coordinated action of both processors.
Solution Approach 2:
The communication processor serves as an intermediary that handles periodic scheduling events independently. It collects events from the application processor and manages the notification transmission to external devices, enabling the application processor to minimize its active time and reduce power consumption while maintaining all necessary functions.
3Speed
If the application processor remains active for event processing, then processing speed is improved, but current consumption increases
Solution Approach 1:
The patent segments the processing workload by implementing a communication processor that handles event collection and notification transmission. This allows the application processor to remain in sleep state and only wake up when necessary, reducing current consumption while maintaining acceptable processing speed through the dedicated communication processor handling time-sensitive events.
Data Source
