Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional hydration systems face issues such as inconvenient fluid access, safety concerns during activities, difficulty in quickly interchanging components, and challenges in cleaning and filling the hydration bags, as well as the need for users to suck fluids through a tube, which can be taxing especially during exertion or for elderly users.
Innovation Solution
A magnetic quick connect system for fluid delivery systems that includes a male and female coupling member with magnetic materials for easy attachment and detachment, allowing for hands-free hydration and easy component interchange, along with a splicer for integrating fluid channels and an actuation system for fluid delivery without suction.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional friction-fit or threaded connectors are used, then components can be securely connected, but users must use two hands and visual alignment to connect and disconnect components, reducing ease of operation
Solution Approach 1:
The patent replaces traditional mechanical connection mechanisms (friction-fit, threaded connectors requiring hand manipulation) with a magnetic connection system. Magnets embedded in the connector housing automatically attract and secure components when brought into proximity, eliminating the need for manual threading or friction-based assembly. This magnetic field-based approach allows for one-handed operation and automatic alignment, directly resolving the contradiction between ease of operation and device complexity.
2Speed
If mechanical quick-connect buttons are used, then components can be quickly disconnected, but the connectors can snag on surrounding objects and create safety hazards
Solution Approach 1:
The magnetic connector system separates the connection function into two independent magnetic housings that can be easily separated by pulling apart. This segmentation eliminates the need for protruding buttons or levers that could snag on surrounding objects. The distributed magnetic fields provide secure connection during use, while simple linear separation allows quick disconnection without creating snagging hazards, resolving the contradiction between disconnection speed and safety.
3Productivity
If users wait until thirsty to hydrate, then fluid consumption occurs, but by then the body is already dehydrated and performance is reduced
Solution Approach 1:
The magnetic connector system enables self-service hydration by allowing users to quickly disconnect and refill fluid containers without requiring assistance or complex manipulation. The automatic magnetic connection and simple pull-apart disconnection mechanism enable rapid refilling during activities, reducing the time loss associated with hydration and allowing users to maintain optimal performance by staying proactively hydrated rather than waiting until thirsty.
4Ease of operation
If conventional connectors are used, then components can be connected, but cleaning and filling hydration bags remains difficult and inconvenient
Solution Approach 1:
The magnetic connector system allows the fluid container (hydration bag) to be easily extracted from the connector housing by simply pulling apart the magnetic connection. This extraction capability enables users to remove the bag for cleaning or refilling without disassembling complex connector mechanisms. The open-ended magnetic connection facilitates easy access to the bag opening for cleaning and filling operations, resolving the contradiction between ease of maintenance and connector structure complexity.

AI summary
A magnetic quick connect for a fluid delivery system includes a male coupling member and a female coupling member. The male coupling member defines a first outer fluid communication path and includes a first magnetic material. A first inner member is disposed within the first outer fluid communication path and defines a first inner communication path. The female coupling member defines a second outer fluid communication path and includes a second magnetic material. A second inner member is disposed within the second outer fluid communication path and defines a second inner communication path. The male and female coupling members are detachably held together by an attractive force between the first and second magnetic materials such that the first and second outer communication paths are held in fluid communication, and the first and second inner communication paths are held in fluid communication.
