Advertising Content Update Timing in Power-Saving Electronics
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing electronic devices struggle to efficiently update advertising content before its expiration time, particularly in power-saving modes, leading to potential display issues and inefficiencies.
Innovation Solution
The electronic apparatus includes a communication device, memory, and processor configured to acquire and store advertising content, switch operating modes based on expiration times, and update content during power-saving modes to ensure timely display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Use of energy by moving object
If the electronic apparatus operates in power-saving mode to reduce energy consumption, then energy efficiency is improved, but the ability to update advertising content before expiration deteriorates
Solution Approach 1:
The system performs preliminary actions by setting a predetermined time for mode switching before the advertising content actually expires. This allows the apparatus to wake from power-saving mode in advance to update the advertising content, ensuring the content is refreshed before expiration while still maintaining power-saving operation for most of the time.
Solution Approach 2:
The system dynamically switches between power-saving mode and active mode based on the expiration time of advertising content. The operating mode is not static but changes according to the temporal characteristics of the advertising content, optimizing the balance between energy consumption and content update reliability.
2Loss of information
If the electronic apparatus frequently switches operating modes to update advertising content, then advertising content freshness is improved, but system stability and power efficiency deteriorate
Solution Approach 1:
The system calculates and sets a predetermined time for mode switching that is earlier than the actual expiration time of advertising content. This preliminary timing allows the system to update content efficiently without unnecessary frequent mode switches, reducing energy waste while maintaining content freshness.
3Use of energy by moving object
If the electronic apparatus waits until advertising content expiration to update, then power consumption is minimized, but display reliability and user experience deteriorate
Solution Approach 1:
The system performs the mode switching and content update action in advance before the advertising content actually expires. By setting a predetermined time for switching to active mode, the system ensures content is updated proactively, maintaining display reliability while minimizing the duration of high-power operation.
Solution Approach 2:
The system provides a time cushion by setting the mode switching time earlier than the content expiration time. This cushion period ensures that even if there are delays in the update process, the advertising content will still be updated before expiration, preventing display failures.

AI summary
An electronic apparatus comprising a communication device to communicate with an external device; a memory; and at least one processor to acquire information about advertising content through the communication device and store, in the memory, the advertising content corresponding to the information. The at least one processor sets a preset time at which an operating state of the electronic apparatus is switched to update advertising content based on an expiration time of the advertising content and the operating mode of the electronic apparatus being switched to a power saving mode.
