Video Communication Battery Level Overlay
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current video communication devices lack a mechanism to automatically alert the other party about the battery energy level of the user's device, leading to unexpected video communication interruptions due to battery depletion, as traditional power prompting functions only inform one party and not the other.
Innovation Solution
A video communication method and device that display the current battery energy level of one party's device on the video feed received by another party, using energy indicators superimposed on video frames, with specific indicators for different energy levels and a flickering red indicator when the battery level falls below a threshold, ensuring the other party is aware of the energy status.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If traditional power prompting function is used, then one party can know their own battery energy level, but the other party cannot know the battery energy level of the user's apparatus
Solution Approach 1:
The patent uses the video communication channel as an intermediary to transmit battery energy level information. The energy status indicator is embedded within the video feed, allowing the other party to receive battery information through the existing communication medium without requiring separate dedicated signaling channels or additional complex infrastructure.
Solution Approach 2:
The patent combines the battery energy level information with the video communication stream by superimposing the energy status indicator on the video frames. This merging approach allows both the video content and the battery status information to be transmitted together through the same channel, eliminating the need for separate information streams and reducing overall system complexity.
2Reliability
If video communication is used, then dynamic video information and audio information can be sent, but energy consumption is greatly increased
Solution Approach 1:
The patent implements a feedback mechanism where the battery energy level information is continuously monitored and displayed to the other party during video communication. This allows both parties to be aware of the energy status and can take preventive actions (such as ending the call or charging the device) before the battery is depleted, thereby ensuring communication continuity and avoiding unexpected interruptions.
Solution Approach 2:
The patent enables preliminary action by providing advance warning of low battery status through the energy status indicator. When the battery level drops below the threshold, the other party is notified in advance and can proactively end the video communication or take other measures to prevent sudden disconnection, thus maintaining reliable communication throughout its intended duration.
3Measurement precision
If energy indicator is superimposed on every frame, then real-time monitoring is achieved, but data transmission volume increases
Solution Approach 1:
The patent uses periodic action by setting a threshold value (5% of total battery energy) and only updating the energy status indicator when the battery level crosses this threshold or changes significantly. Instead of updating every frame regardless of change, the system selectively updates based on meaningful changes in battery status, reducing redundant data transmission while maintaining effective monitoring.
Solution Approach 2:
The patent applies partial action by updating the energy indicator selectively rather than continuously on every frame. The system determines which frames require updating based on whether the battery level has changed sufficiently to warrant notification, thereby transmitting only the necessary amount of information to maintain accurate monitoring without excessive data volume.
