Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for controlling electronic devices during a fall event, such as a slidable device transitioning from an extended to a closed state, suffer from significant latency due to lengthy signal transmission processes through software stacks, which are inadequate for emergency situations.
Innovation Solution
An electronic device design that includes direct port connections between sensors and driving modules, allowing for immediate control commands to be transmitted through processor ports, bypassing conventional software stacks, thereby reducing latency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional software stack transmission process is used for fall detection control, then the control signal can be transmitted through standard protocols, but the response time is significantly delayed and unsuitable for emergency situations
Solution Approach 1:
The patent segments the control signal transmission path into two distinct channels: a conventional software stack path for normal operations and a direct hardware path for emergency fall detection. This segmentation allows the emergency control signal to bypass the lengthy software processing layers while maintaining standard protocol compliance for non-critical operations.
Solution Approach 2:
The patent introduces a direct hardware connection as an intermediary channel between the sensor and driving module. This intermediary path enables emergency control signals to transmit directly without passing through the conventional software stack, significantly reducing response time while the software stack remains available for routine control tasks.
2Speed
If direct port connection is implemented for fall detection, then response time is significantly reduced, but the device complexity increases
Solution Approach 1:
The patent divides the connection architecture into conventional software-connected components and a specialized direct-hardware connection for fall detection. This segmentation isolates the complexity of the direct connection to only the necessary emergency detection path, while the rest of the system continues to use standard software-based connections.
Solution Approach 2:
The patent applies local quality by implementing direct port connections only for the specific fall detection control path where speed is critical, while other control paths continue to use the conventional software stack. This localized application of direct connections minimizes overall device complexity while achieving the required performance improvement for emergency responses.

AI summary
An electronic device for controlling a driving module on the basis of detection of a fall, and/or a control method therefor. The control method for the electronic device may include: identifying whether the electronic device is falling based on sensing data transmitted from at least one sensor included in a second housing of the electronic device; outputting an interrupt signal through a first port of a component of the electronic device based on identifying that the electronic device is falling; and outputting, to at least one driving module of the electronic device, a control command for controlling the at least one driving module in order to insert the second housing extracted from a first housing into the first housing of the electronic device, based on receiving the output interrupt signal through a second port of a processor directly connected to the first port.
