Self-Righting Support for Vertical Medicament Delivery Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medicament delivery devices with multi-chamber containers face challenges in maintaining stability and proper orientation during use, leading to potential damage and inefficiencies in mixing and dosing due to their shape and the need for manual priming, which can result in uneven medicament distribution and reduced accuracy in delivery.
Innovation Solution
A self-righting supporting device with a curved or flat top surface and a spherical or elliptical base that automatically orients the medicament delivery device in a vertical position, preventing it from rolling or falling, and includes a mechanical adaptor to accommodate various shapes and sizes of devices, facilitating gas escape and improving mixing homogeneity.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the medicament delivery device is left in a horizontal or random position, then the device structure is simple and easy to store, but the device may fall or roll away causing damage and the medicament mixing and delivery accuracy deteriorates
Solution Approach 1:
The support device incorporates a spherical base that enables the device to automatically right itself and maintain a stable vertical position. The spherical geometry allows the device to roll to and remain in an upright orientation, preventing it from falling or rolling away, while keeping the support structure relatively simple.
2Manufacturing precision
If the medicament delivery device is not properly oriented vertically, then the device can be stored in any position, but the gas escape and mixing efficiency deteriorates leading to inaccurate dosing
Solution Approach 1:
The support device automatically orients the medicament delivery device in a vertical position without requiring manual intervention. The spherical base design enables the device to self-right and maintain proper orientation, facilitating gas escape and mixing efficiency while ensuring accurate dosing without complex user operations.
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 self-righting device ensures the medicament delivery device remains upright, enhancing user experience, improving mixing efficiency, and maintaining the accuracy of medicament delivery by preventing damage and ensuring proper orientation, which aids in gas escape and priming, thus ensuring a consistent and accurate dose.
Implementation Method 1
The support body has a mass, a center of gravity and a shape such that the self-righting device, when positioned on a substantially horizontal surface, moves from an unbalanced position to an upright position

AI summary
A self-righting device is disclosed having a support body for supporting a medicament delivery device, where the support body has a mass, a center of gravity (G) and a shape such that the self-righting device, when positioned on a substantially horizontal surface, moves from an unbalanced position to an upright position. The self-righting device can also have a mechanical adaptor configured for attachment to the support body and for holding an elongated medicament delivery device at an angle less than 30 degrees from a vertical axis when the self-righting device is in the upright position. An assembly of a self-righting device and an elongated medicament delivery device is also provided.
