Emergency Rescue Accessory Trigger for Secure User State Signaling

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing emergency rescue systems on smartphones are limited in functionality and difficult to operate during emergencies due to small buttons prone to malfunction and lack of integration with other applications, and there is a need for a device that can generate a rescue signal safely and securely.

Innovation Solution

An accessory device separate from the user terminal generates a trigger signal, capturing image and audio data to create user state data, which is encrypted and transmitted to a management server through Bluetooth communication, ensuring secure and stable signal transmission.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a function button is provided on a smartphone to generate an emergency rescue signal, then the emergency signal can be transmitted to a management server, but the button is very small in size and prone to accidental pressing causing malfunction

Engineering Contradiction:

Improveemergency signal transmission reliabilityVSAvoidaccidental button pressing

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The emergency signal generation function is segmented from the smartphone into a separate accessory device. This physical separation eliminates the risk of accidental pressing on the smartphone's small button while maintaining the emergency signal transmission capability through wireless communication between the accessory device and smartphone.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The accessory device acts as an intermediary between the user and the smartphone's emergency signal system. It captures the user's intent through a large physical switch, processes the trigger signal, and communicates with the smartphone to generate and transmit the emergency rescue signal, thereby preventing direct interaction with the smartphone's vulnerable button.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If a separate accessory device is used to generate emergency rescue signals, then accidental activation is prevented and personal information security is ensured, but the device complexity increases

Engineering Contradiction:

Improveaccidental activation preventionVSAvoidsystem structure

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The accessory device is designed to perform multiple functions: it serves as an emergency signal trigger, a security authentication device, and a communication interface with the smartphone. By consolidating these functions into a single device, the system complexity is managed while achieving reliable accidental prevention and security.

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The accessory device autonomously handles trigger signal generation and authentication, reducing the need for complex user interactions or additional components. The device self-manages the emergency signal initiation process, simplifying the overall system while maintaining high reliability.

Inventive Principle:

Principle #25Self-service

3Reliability

If image data and audio data are captured and encrypted for emergency signal transmission, then personal information security is improved, but the data processing time and energy consumption increase

Engineering Contradiction:

Improvepersonal information securityVSAvoiddata processing time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

Data encryption is performed as a preliminary action immediately when image and audio data are captured during an emergency event. This ensures personal information security is maintained from the outset, while the encrypted data can be efficiently transmitted without requiring additional decryption steps at later stages.

Inventive Principle:

Principle #10Preliminary action
