Irrigation Connector with Magnetic Release for Limited Dexterity
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users with poor hand dexterity face challenges in connecting and disconnecting connectors in anal or stomal irrigation systems, particularly due to reduced pinch grip ability.
Innovation Solution
A connector system with a toggle arm mechanism and magnetic holds that allows users to connect by pushing the connector into the container, and release by moving a magnet over the container, eliminating the need for pinch grip.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a traditional connector requires pinch grip for connection and disconnection, then the connector can be securely attached, but users with poor hand dexterity cannot operate it
Solution Approach 1:
The patent replaces the traditional mechanical pinch-grip operation with a magnetic field-based release mechanism. A magnet is positioned near the connector to interact with a magnetic element in the locking mechanism, enabling the user to release the connector by simply moving the magnet rather than applying manual pinch force. This substitution allows users with poor hand dexterity to operate the connector securely without requiring strong pinch grip ability.
Solution Approach 2:
The patent introduces a magnetic field as an intermediary between the user and the connector locking mechanism. Instead of direct mechanical manipulation, the user interacts with the system through magnetic attraction/repulsion forces that act on the magnetic element within the connector. This intermediary mechanism translates simple magnet movement into the complex locking and unlocking actions, making the system accessible to users with limited hand dexterity while maintaining secure connection.
2Ease of operation
If a magnetic release mechanism is added to the connector, then ease of operation is improved, but device complexity increases
Solution Approach 1:
The magnetic element serves multiple functions within the connector mechanism: it acts as part of the locking structure, provides tactile feedback to the user, and enables magnetic release operation. By making this single component multi-functional, the patent avoids adding separate dedicated magnetic release components that would increase complexity. The same structural element that provides mechanical locking also interacts with the magnetic field for release, achieving ease of operation without proportionally increasing device complexity.

Function Achieved in This Case
Enables users with limited dexterity to securely connect and disconnect the connector without relying on pinch grip, providing a user-friendly and reliable irrigation system operation.
Implementation Method 1
the toggle arm further comprising a first hold which is configured to be in a magnetic hold with a second hold, and thereby hold the connector in a locked position
