Injection Device Packaging Handling Recess and Positioning Rib
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current medical tray packaging for injection devices is complex to open, especially for users with reduced dexterity, as it requires removal of a lid and reaching into a narrow channel, making extraction difficult.
Innovation Solution
The packaging includes a channel with a handling recess and a positioning rib that allows for easier access and gripping of the injection device, with a positioning rib that protrudes from the base wall into the channel to facilitate insertion and extraction, and a label positioned to remain visible during removal.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the tray is made non-collapsible for device protection, then device protection is improved, but extraction complexity increases
Solution Approach 1:
The packaging is divided into a tray portion and a lid portion that can be separated. The lid is removable from the tray, allowing the device to be extracted from the tray channel without requiring the entire packaging to be collapsed or destroyed. This segmentation resolves the contradiction by maintaining tray rigidity for protection while enabling easy extraction through lid removal.
2Reliability
If the channel is made narrow for device containment, then device containment is improved, but user accessibility worsens
Solution Approach 1:
The lid is designed to be removable along a separation line that provides lateral access to the device in the channel. Instead of requiring vertical reaching into the narrow channel, users can remove the lid from the side, creating a new access dimension. This resolves the contradiction by maintaining narrow channel containment while improving user accessibility through lateral lid removal.
3Reliability
If a tear away lid is used for closing, then sealing is improved, but opening complexity increases
Solution Approach 1:
The lid is completely extracted/removed from the tray rather than requiring tearing or breaking through. The lid portion is designed to be fully separable from the tray portion along a defined separation line, allowing users to simply lift the lid away without complex tearing motions. This resolves the contradiction by maintaining sealing when closed while simplifying opening to a single removal action.

AI summary
A kit including a packaging and an injection device is described. The injection device defines a positioning recess. The packaging includes a channel extending longitudinally to accommodate the injection device. The channel includes a first longitudinal wall, a second longitudinal wall opposing the first longitudinal wall, and a base wall extending between the first longitudinal wall and the second longitudinal wall. The packaging also includes a first handling recess defined by the first longitudinal wall and a second handling recess defined by the second longitudinal wall. The packaging also includes a positioning rib protruding from the base wall into the channel for insertion into the positioning recess of the injection device.
