Strapless Bag Attachment Mechanism Using Magnets to Reduce Chafing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing bag systems that use straps for attachment cause rubbing and chafing, limiting storage capacity and comfort during movement, and are not integrated with existing apparel.
Innovation Solution
A strapless bag attachment mechanism using magnetic and loop systems that allows secure attachment to apparel without straps, providing increased storage and comfort.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If straps are used to secure the bag, then the bag can be attached to the user, but rubbing and chafing occur proportional to the load
Solution Approach 1:
The patent removes the strap component entirely and replaces it with a magnetic attachment system. The magnet is embedded in the bag body, allowing the bag to attach to magnetic surfaces (such as belts or apparel) without direct contact between fabric and skin, thereby eliminating rubbing and chafing while maintaining secure attachment.
Solution Approach 2:
The patent replaces the mechanical strap fastening system with a magnetic field-based attachment system. Instead of using physical straps that wrap around the body, the bag uses embedded magnets to attach to magnetic surfaces, eliminating the harmful friction and chafing caused by traditional mechanical straps.
2Reliability
If straps are used to secure the bag, then the bag can be attached to the user, but comfort is reduced during movement
Solution Approach 1:
The patent removes the uncomfortable strap component and replaces it with a magnetic attachment system that distributes the load without concentrating friction points. This extraction of the strap element directly improves comfort during movement while maintaining secure attachment through magnetic force.
Solution Approach 2:
The patent substitutes the mechanical strap system with a magnetic field-based attachment, which provides secure holding without the friction and discomfort associated with straps during physical movement. The magnetic field creates a non-contact attachment that maintains security while enhancing comfort.
3Reliability
If straps are used to secure the bag, then the bag can be attached to the user, but storage space is limited
Solution Approach 1:
The patent removes the strap component that consumed space and replaced it with a compact magnetic attachment system. This extraction of the strap element and replacement with a more space-efficient magnetic system increases the available storage volume within the bag while maintaining secure attachment capability.

AI summary
A bag with strapless attachment mechanism is provided. The bag includes a body having at least one interior surface and at least one exterior surface. The bag includes at least two openings each having a closing mechanism for securing the opening in a closed position. Strapless attachment mechanism has a body having at least one magnet disposed in a first end and at least one magnet disposed on a second end distal from the first end. The first end of the body is at least partially disposed on the at least one interior surface of the bag, proximate to one of the openings. A user can wrap the strapless attachment mechanism around an item and attach the at least one magnet of the first end to the at least one magnet of the second, securing the bag to the item of apparel.
