Weightlessness Duration Threshold for Fall Data Reporting
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices consume excessive power when reporting fall data, leading to unnecessary power consumption and inefficient data reporting, especially when falls do not result in damage.
Innovation Solution
Implementing a method in electronic devices that includes a processor, timer, fall detection sensor, and communication module to record continuous weightlessness duration and obtain falling data only when the duration exceeds a preset threshold, thereby reducing power consumption and reporting effective data only when damage is likely.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the electronic device reports all falling data regardless of duration, then complete fall information is captured, but power consumption increases excessively
Solution Approach 1:
The patent changes the parameter of weightlessness duration from an unthresholded continuous measurement to a threshold-based discrete trigger. By setting a preset duration threshold, the system transforms the detection parameter from always-active to conditionally-active, reducing power consumption while maintaining detection reliability for significant falls.
Solution Approach 2:
The patent segments the fall detection process into distinct phases: weightless state detection, duration timing, threshold comparison, and conditional data reporting. This segmentation allows the system to activate full reporting functions only when necessary (when duration exceeds threshold), rather than continuously, thereby reducing overall power consumption.
2Loss of information
If the electronic device continuously monitors and reports fall data, then all fall events are recorded, but unnecessary data transmission occurs when no damage happens
Solution Approach 1:
The patent performs preliminary assessment of the fall event by measuring the weightlessness duration before triggering full data reporting. This preliminary action (duration measurement) acts as a filter to determine whether subsequent detailed monitoring and reporting are necessary, preventing unnecessary data collection and transmission for minor falls.
Solution Approach 2:
The patent extracts only the essential criterion (weightlessness duration) from the full fall detection process to create a simple threshold-based filtering mechanism. By taking out this key parameter and using it as a gatekeeper, the system avoids the complexity and power consumption of continuous full-parameter monitoring while still capturing meaningful fall events.
3Measurement precision
If the electronic device activates all sensors and communication modules during any fall event, then comprehensive data is collected, but power consumption is inefficient
Solution Approach 1:
The patent makes the activation of sensors and communication modules dynamic rather than static. The system adjusts its operational state based on the measured weightlessness duration: for short durations, only essential monitoring remains active; for durations exceeding the threshold, full sensor arrays and communication modules are activated. This dynamic adaptation optimizes power consumption while maintaining detection sensitivity.

AI summary
A method for reporting data and related products are provided. The method is applicable to an electronic device. The electronic device includes a processor, and a timer coupled with the processor, a fall detection sensor coupled with the processor, and a communication module coupled with the processor. The method includes the following. When the electronic device is in a weightlessness state, a continuous weightlessness duration of the electronic device is recorded. When the continuous weightlessness duration is longer than a preset duration, falling data of the electronic device is obtained. The falling data is transmitted to the preset device. By adopting technical schemes of implementations of the disclosure, on the one hand, power consumption of the electronic device can be reduced, and on the other hand, reporting of effective falling data can be achieved, where the effective falling data is obtained and reported when the electronic device is considered to be damaged due to falling.
