Solution Overview
Problem
Electronic devices face battery consumption issues due to continuous power usage even when not actively being used, especially with advancements in wireless communication, leading to reduced battery capacity and duration.
Innovation Solution
An electronic apparatus with a software operation method that manages power supply by classifying software into different execution periods, periodically switching between sleep and wake-up states to minimize power consumption, using a transceiver, timer, and controller to execute specific software based on data transmission needs.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic apparatus continuously operates to maintain network connection and execute software, then the network connectivity and software execution are maintained, but the battery consumption increases significantly
Solution Approach 1:
The electronic apparatus periodically switches between wake-up states and sleep states based on predetermined intervals. During wake-up states, the apparatus executes software and maintains network connection. During sleep states, the apparatus enters low-power mode to conserve battery. This periodic cycling resolves the contradiction by maintaining network connectivity only when necessary while reducing energy consumption during idle periods.
Solution Approach 2:
The system dynamically adjusts its operational state based on timing conditions and software execution requirements. The controller transitions the apparatus between different power states (wake-up and sleep) depending on whether software execution is currently needed. This dynamic state adjustment allows the system to maintain reliability when required while optimizing energy efficiency during non-critical periods.
2Duration of action of moving object
If the electronic apparatus frequently switches between sleep and wake-up states to save power, then the battery life is extended, but the time to convert between states increases
Solution Approach 1:
The electronic apparatus performs preliminary actions during wake-up states by pre-executing software tasks and preparing data before transitioning to sleep state. This advance preparation reduces the amount of work needed when waking up, thereby minimizing state conversion time while still allowing for extended sleep periods to conserve battery life.
3Adaptability or versatility
If the electronic apparatus executes multiple software programs with different execution periods, then the functional requirements are met, but the power management complexity increases
Solution Approach 1:
The electronic apparatus segments software programs into different categories based on their execution periods (first execution period for frequent updates, second execution period for less frequent updates). The controller manages each segment independently with appropriate wake-up intervals, simplifying power management while still meeting diverse software requirements. This segmentation allows the system to handle multiple software types without proportionally increasing complexity.

AI summary
A software operation method for managing power supply and an electronic apparatus using the same are provided. The electronic apparatus includes a controller configured to convert a state into a sleep state, to convert the sleep state into a wake-up state for every first interval and to execute the first software. The controller is configured to convert the wake-up state into the sleep state, if an execution of the first software ends. The controller is configured to convert the sleep state into the wake-up state for every second interval and to execute the second software. The controller is configured to convert the wake-up state into the sleep state, if an execution of the second software ends. A classification into the first software and the second software is made based on an execution period.
