Drug Delivery Shell Labels for Volume-Specific Inspection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drug delivery devices require different shell designs or window sizes for medicament containers with varying deliverable volumes, leading to increased costs and complexity.
Innovation Solution
A label with a cutout or transparent area is used, sized to match the deliverable volume, allowing compatibility with different medicament containers within the same shell without altering the shell design.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If different shell designs or window sizes are used for medicament containers with varying deliverable volumes, then visual inspection capability is improved, but device complexity and manufacturing cost increase
Solution Approach 1:
The shell is divided into a transparent area and an opaque area. The transparent area allows visual inspection of the medicament container, while the opaque area can be covered by labels with cutouts or transparent areas that are customized for different deliverable volumes. This segmentation allows the shell structure to remain standardized while adapting the labeling to provide precise visual inspection for different volumes.
Solution Approach 2:
A label with a cutout or transparent area acts as an intermediary between the standardized shell and the need for volume-specific visual inspection. The label is applied to the opaque area of the shell, and its cutout or transparent area is sized to match the deliverable volume of the medicament container, enabling precise visual inspection without requiring different shell designs.
2Measurement precision
If different shell designs are used for varying medicament volumes, then visual inspection is improved, but manufacturing cost increases
Solution Approach 1:
A single standardized shell design with a transparent area and an opaque area serves multiple functions: it provides structural containment, allows visual inspection through the transparent area, and accepts labels with volume-specific cutouts or transparent areas. This universal shell design reduces manufacturing costs by eliminating the need for multiple shell variants while still enabling precise visual inspection for different medicament volumes through the interchangeable labels.
3Measurement precision
If the shell is made transparent for visual inspection, then deliverable volume visibility is improved, but obscuration of other internal components is reduced
Solution Approach 1:
The shell is designed with different optical properties in different areas: the first area is transparent to allow visual inspection of the medicament container and deliverable volume, while the second area is opaque to obscure other internal components. This local differentiation of optical quality allows simultaneous achievement of volume visibility and component obscuration without requiring the entire shell to be transparent or opaque.

AI summary
The present disclosure relates to a drug delivery device, comprising a shell adapted to contain one of a plurality of medicament containers prefilled with different deliverable volumes of a medicament. The shell is transparent at least in an area adapted to contain the medicament container, and a label adapted to be arranged on the shell. The label comprises a foil having a first surface and a second surface, which is adapted to be connected to the shell. At least one cutout or transparent area is arranged in the foil adapted to be placed on the shell such that a medicament container arrangeable or arranged within the shell is visible through the cutout or transparent area. The cutout or transparent area exhibits a size adapted to allow inspection of the deliverable volume of medicament within the medicament container when the label is applied to the shell.
