Solution Overview

Problem

Current anti-asphyxiation devices require manual operation and assistance, making them difficult for individuals, especially children and infants, to use safely and effectively, and can lead to secondary injuries due to variable pressure application.

Innovation Solution

A portable, fully-automatic first-aid device that generates a constant negative pressure suction force using a piston module driven by a spring mechanism, allowing self-operation without manual assistance, with a mask and one-button trigger for easy use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If manual operation devices are used, then device complexity is reduced, but ease of operation deteriorates and reliability worsens due to requiring assistance and variable pressure application

Engineering Contradiction:
Improveease of operationVSAvoiddevice complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The device enables self-service operation through a simple button trigger mechanism that automatically activates the suction system. The user only needs to press one button, and the device autonomously completes the entire suction process without requiring manual assistance or complex manual operations, directly resolving the contradiction between ease of operation and device complexity

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces complex manual mechanical operations with an automated mechanical system. The button trigger initiates an automated sequence where the suction mechanism is activated through mechanical linkage, eliminating the need for manual suction operations and reducing operational complexity while maintaining mechanical reliability

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If manual suction operation is performed, then device complexity is reduced, but reliability deteriorates due to variable pressure and potential secondary injuries

Engineering Contradiction:
ImprovereliabilityVSAvoiddevice complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The device incorporates a feedback mechanism through the button trigger system that controls the suction activation. The trigger provides user feedback and simultaneously activates the suction mechanism, ensuring reliable operation while maintaining simple device structure. The feedback loop ensures the suction is activated only when intended, improving reliability without adding complex control systems

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The patent extracts the complex manual suction operation from the user and transfers it to an automated mechanical system. The suction mechanism is separated from manual control and activated automatically through the button trigger, eliminating variability in pressure application and preventing secondary injuries while keeping the overall device structure simple

Inventive Principle:
Principle #2Taking out (Extraction)

3Ease of operation

If assistance from another person is required, then ease of operation deteriorates, but device complexity is reduced

Engineering Contradiction:
Improveease of operationVSAvoidextent of automation
Core Design Contradiction:
Ease of operationVSExtent of automation

Solution Approach 1:

The device is designed for self-service operation where the user can independently activate and control the suction function through a simple button trigger. This eliminates the need for assistance from another person while maintaining appropriate automation levels, directly resolving the contradiction between ease of operation and extent of automation

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The device segments the operation into a simple trigger action (button press) and an automated execution phase (suction activation). This segmentation allows the user to perform only the simple triggering action without needing to assist with the complex suction operation, improving ease of operation while maintaining reasonable automation

Inventive Principle:
Principle #1Segmentation
