Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Devices connected to the Internet experience disconnection due to loss of connectivity information over time, leading to inefficient power consumption from continuous connectivity keeping processes.
Innovation Solution
An electronic apparatus with a first processor for active connectivity and a second processor for power-saving mode switching, transmitting connectivity keeping information at intervals to maintain network connectivity while reducing power consumption.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If devices continuously perform connectivity keeping process to maintain Internet connection, then network connectivity is maintained, but power consumption increases
Solution Approach 1:
The patent implements periodic connectivity keeping by having the processor wake up at predetermined intervals to transmit connectivity keeping information to the server, rather than maintaining continuous communication. This periodic action maintains network connectivity while allowing the device to remain in low-power sleep mode between intervals, directly resolving the contradiction between connectivity reliability and power consumption
Solution Approach 2:
The patent uses preliminary action by setting a timer in advance that automatically triggers connectivity keeping transmissions at predetermined intervals. The timer is configured beforehand to wake the processor from sleep mode at appropriate times, ensuring connectivity maintenance occurs proactively before disconnection happens, while minimizing the time the processor needs to be active
2Reliability
If devices remain turned on to maintain connectivity, then network connection is kept, but power efficiency decreases
Solution Approach 1:
The system transitions from continuous operation to periodic connectivity keeping, where the processor wakes up at predetermined intervals to transmit connectivity information and then returns to sleep mode. This periodic operation maintains connectivity reliability while dramatically improving power efficiency by minimizing the duration the processor remains active
Solution Approach 2:
The device performs self-service connectivity maintenance by using its own periodic wake-up mechanism to transmit connectivity keeping information without requiring continuous external power or intervention. The timer-based system automatically manages the connectivity keeping process, allowing the device to serve its own connectivity needs efficiently

AI summary
An example electronic apparatus includes a communication circuitry; a power supply; a first processor configured to have a first mode which receives first power from the power supply and connects with a server through the communication circuitry to transmit and receive information, and a second mode which receives no power or second power lower than the first power from the power supply; and a second processor configured to repetitively output a mode switching signal within a preset range of time interval based on the second mode of the first processor, wherein the first processor is switched over to the first mode based on the mode switching signal, is configured to transmit connectivity keeping information to the server through the communication circuitry and is switched over to the second mode.
