Backpack Magnetic Slide Track Fastener for Protective Layer Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current sanitization techniques and products, such as hand sanitizers and disinfectant sprays, have limitations including skin irritation, short duration of effectiveness, and user unfriendliness, which do not adequately prevent the spread of contagious diseases through surface and skin contact.
Innovation Solution
A backpack with a sleeve, shoulder straps, a protector, and a magnetic slide track fastener that includes a self-disinfecting fabric protector which can be protracted and retracted to provide a protective layer between the user's clothing and seating surfaces, offering prolonged and effective protection against contagious microbes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If hand sanitizers are used continuously or overused, then the spread of contagious diseases is reduced, but skin irritation, cracking, and bleeding occur
Solution Approach 1:
The patent introduces a protective barrier (glove or protective layer) as an intermediary between the user's skin and the external environment. This barrier allows the user to maintain hygiene and protection without direct contact with sanitizers or contaminated surfaces, thereby preventing skin damage while maintaining disease prevention efficacy.
Solution Approach 2:
The patent employs disposable protective gloves or single-use protective layers that can be discarded after use. This eliminates the need for continuous reapplication of sanitizers and prevents cumulative skin damage from repeated exposure to alcohol-based sanitizers, while maintaining reliable protection throughout the duration of use.
2Reliability
If hand sanitizers are applied, then protection against viruses and bacteria is provided, but the effectiveness lasts only for two minutes
Solution Approach 1:
The patent employs disposable protective gloves or single-use protective layers that can be discarded after use. This eliminates the need for continuous reapplication of sanitizers and prevents cumulative skin damage from repeated exposure to alcohol-based sanitizers, while maintaining reliable protection throughout the duration of use.
Solution Approach 2:
Instead of relying on the limited two-minute effectiveness of hand sanitizers, the patent applies a protective layer that provides extended coverage beyond the short duration of sanitizer effectiveness. This excessive action ensures continuous protection throughout the day without requiring frequent reapplication.
3Reliability
If disinfectant sprays are used, then surfaces can be disinfected, but improper spraying leaves areas untreated and causes breathing discomfort
Solution Approach 1:
The patent extracts the disinfection function from the user's hands and transfers it to a protective barrier. The protective layer itself acts as the disinfection mechanism, eliminating the need for users to manually spray and apply disinfectants, thereby ensuring complete coverage without breathing discomfort or missed areas.
Solution Approach 2:
The protective barrier provides self-service disinfection by being made from materials that inherently prevent microbial transmission. The material itself performs the disinfection function without requiring user action to apply sprays or wipes, making the process automatic and foolproof.
4Duration of action of moving object
If a backpack is designed with a protective layer, then prolonged protection against surface contact is provided, but the device complexity increases
Solution Approach 1:
The protective layer is integrated into the backpack in such a way that it serves multiple functions: it protects against surface contact, maintains hygiene, and can be adjusted or removed as needed. This multi-functionality justifies the added complexity by providing comprehensive protection without requiring separate dedicated components.
Solution Approach 2:
The patent uses flexible protective films or thin barrier layers that can be easily integrated into the backpack structure. These thin films provide effective protection while adding minimal bulk or complexity to the backpack design, allowing for prolonged protection without significantly increasing device complexity.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The backpack provides a user-friendly, prolonged, and effective means to prevent the spread of contagious diseases by offering a protective layer that can be easily deployed and retracted, reducing the risk of infection through surface and skin contact.
Implementation Method 1
The magnetic slide track fastener includes a magnetic ring fixed at a bottom end of each of the pair of shoulder straps... The magnetic slide track fastener also includes the magnetic pin fixed at a bottom end of each of the pair of pulling straps... The magnetic pin is removably attached with the magnetic ring via the upward sliding motion of the magnetic pin through the curved space to hold the middle padded section in a retracted position inside the sleeve.
Data Source
AI summary
A backpack for preventing infections from surface and skin contact is disclosed. The backpack includes a sleeve, a pair of shoulder straps, and a protector including a top handle section connected with a pair of pulling straps, a middle padded section coupled to the top handle section, and a bottom section. Furthermore, the backpack includes a magnetic slide track fastener including a magnetic ring fixed at a bottom end of each of the pair of shoulder straps, and a magnetic pin fixed at a bottom end of each of the pair of pulling straps. When the magnetic pin is released from the magnetic ring via the downward sliding motion, the middle padded section protracts out of the sleeve. The magnetic pin is removably attached with the magnetic ring via the upward sliding motion of the magnetic pin to hold the middle padded section in a retracted position.
