Smartphone Case with Fingerprint Sensor for Automatic Emergency Response
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional emergency relief systems for mobile devices require users to perform noticeable actions or multi-stage operations to call for rescue, which can be difficult in emergency situations, and often result in inadvertent rescue calls and unnecessary mobilization of rescue personnel.
Innovation Solution
A smart phone case that is electrically coupled with the phone's hardware, using a screen-lock application and reporting application driven by fingerprint recognition or electric signals to automatically initiate a rescue call and self-protection functions without noticeable user behavior, and includes features like a Taser or gas spraying for self-defense, with data collection and analysis to verify the authenticity of emergency situations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the user presses the emergency relief button to call for rescue, then the emergency relief function can be activated, but it is difficult for the user to press the button in emergency situations and may cause inadvertent activation
Solution Approach 1:
The system automatically detects emergency situations through sensors (acceleration sensor for falls, microphone for screams) and triggers the emergency relief function without requiring user input. The smart phone case with self-protection module autonomously determines when rescue is needed and activates the appropriate response, eliminating the need for manual button pressing while preventing false alarms through multi-parameter verification.
Solution Approach 2:
The mechanical button-pressing action is replaced by sensor-based detection systems. The acceleration sensor detects fall patterns, the microphone captures scream frequencies, and the fingerprint sensor provides authentication. These sensor systems automatically trigger emergency relief without requiring mechanical user interaction, solving the contradiction between reliability and ease of operation.
2Reliability
If multi-stage data entry or touching operations are required for emergency applications, then data accuracy can be verified, but the response time is delayed and the spot cannot be accessed timely
Solution Approach 1:
The system performs preliminary setup during normal operation by registering fingerprint templates and configuring emergency preferences. When an emergency is detected through sensors, the pre-configured system immediately activates emergency relief functions without requiring any user input or multi-stage operations during the critical response period, thus minimizing time loss while maintaining reliability through pre-verified data.
Solution Approach 2:
The system automatically collects and processes emergency data through sensor arrays (acceleration, microphone, GPS, camera) without requiring user data entry. The fingerprint sensor provides automatic authentication, and the system self-determines the nature of the emergency based on sensor patterns, eliminating time-consuming manual operations while ensuring data accuracy through multiple verification parameters.
3Ease of operation
If text message alone is used for emergency relief calls, then the system is simple to operate, but it is difficult to determine whether the call is genuine
Solution Approach 1:
The emergency relief system integrates multiple detection functions into a single unified system. The acceleration sensor detects falls, the microphone captures screams, the fingerprint sensor provides authentication, and the camera/GPS record location and situation. This multi-functional approach maintains ease of operation (single automatic trigger) while dramatically improving reliability through cross-verification of multiple independent parameters to confirm genuine emergencies.

AI summary
A user protection method using a smart phone case includes: installing a screen-lock application driven with electric signals of at least one of a fingerprint recognition sensor and the case of the smart phone and a reporting application running in conjunction with the screen-lock application, and setting a predetermined option; unlocking the smart phone and simultaneously running the reporting application, if a registered fingerprint is recognized in the fingerprint recognition sensor or if the smart phone receives an electric signal; sending a designated server report data created by capturing and recording a field situation through a camera and microphone of the smart phone that work in conjunction with the reporting application; and linking report data to a predetermined website, converting an address of the website and position information of the smart phone into text message formats, and sending the conversion results to a guardian's smart phone.
