Medicament Container Carrier Adapter for Multi-Size Dose Cartridges
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional medicament delivery devices are limited by the size and shape of their carriers, which cannot accommodate medicament containers of varying sizes, necessitating separate devices for different dosage amounts.
Innovation Solution
A medicament container carrier with an adapter that can accommodate medicament containers of different sizes, ensuring secure fixation and visual access, allowing a single delivery device to administer varying doses.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Quantity of substance
If the carrier is sized to accommodate a larger medicament container for increased dose, then the dose capacity is improved, but the device size and complexity increase
Solution Approach 1:
The carrier is designed with a universal accommodation capability through the adapter mechanism, allowing a single carrier to hold multiple medicament container sizes (first container with first predetermined size, second container with second predetermined size). This eliminates the need for multiple different carriers for different dose capacities.
Solution Approach 2:
The adapter is nested within the carrier body, and the second medicament container is nested within the adapter. This nested structure allows the smaller container and adapter assembly to fit within the overall carrier structure designed for the larger container, enabling size versatility without increasing overall device footprint.
2Adaptability or versatility
If a single carrier is used for different container sizes, then device versatility is improved, but the fixation security may worsen
Solution Approach 1:
The adapter provides customized local fitting features tailored to the second medicament container's specific dimensions and characteristics. The adapter's internal geometry is specifically designed to match the second container's flange and body, ensuring secure fixation despite the adapter being an intermediate component.
Solution Approach 2:
The adapter acts as an intermediary component between the carrier and the second medicament container. It mediates the connection by providing carrier-compatible external features while offering customized internal features for secure container engagement, thus ensuring reliable fixation across different container sizes.
3Reliability
If the adapter includes multiple engagement features, then the fixation reliability is improved, but the device complexity increases
Solution Approach 1:
Multiple fixation functions are merged into the resilient arm component. The resilient arm integrates the engagement element with abutment surfaces and ramp features, combining several fixation mechanisms into a single integrated element that reduces overall structural complexity while maintaining reliable fixation.
Solution Approach 2:
The resilient arm provides dynamic adaptation through its elasticity, allowing it to deflect during engagement and then maintain constant contact pressure. This dynamic feature ensures reliable fixation across different container tolerances without requiring overly complex rigid adjustment mechanisms.

AI summary
Described is a medicament container carrier adapted to hold a first medicament container having a first predetermined size and capable of containing more than a first volume of a medicament. The container carrier comprises a body, and an adapter coupled to the body. The adapter is adapted to hold a second medicament container having a second predetermined size different from the first predetermined size and capable of containing no more than the first volume of the medicament.
