Injection Device Movable Code Concealment Mechanism
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing injection devices do not provide a mechanism to securely conceal and then reveal information codes related to medicaments until after the injection process is complete, which is essential for confirming medicament delivery.
Innovation Solution
An injection device with movable means, such as a plunger or needle shroud, that moves to conceal and then reveal an information code, like a bar code or QR code, through a transparent area of the housing, ensuring the code is not visible until after the injection is finished, allowing confirmation of medicament delivery.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If the information code is made visible on the injection device, then the medicament information can be accessed, but the code may be viewed or scanned before injection is complete compromising delivery confirmation
Solution Approach 1:
The patent applies the dynamics principle by making the information code visibility dynamic rather than static. The code is concealed during the injection process and only becomes visible after injection is complete. This is achieved through a window mechanism that moves or changes opacity in response to injection status, ensuring the code can only be accessed when the medicament has been fully delivered, thus preventing premature scanning while allowing post-injection verification
Solution Approach 2:
The patent implements preliminary action by pre-configuring the window mechanism to control code visibility based on injection progress. The system is designed in advance to automatically conceal the code during injection and reveal it only after completion, eliminating the need for manual intervention to control visibility and ensuring the information is only accessible at the appropriate time
2Reliability
If the information code is concealed during injection, then premature scanning is prevented, but the code must be revealed after injection for verification
Solution Approach 1:
The patent applies the self-service principle by designing the window mechanism to automatically control code visibility based on injection status without requiring manual intervention. The system self-regulates when the code becomes visible by detecting injection completion through the plunger position or other injection parameters, eliminating the need for users to manually reveal or conceal the code while ensuring it is only accessible at the appropriate time
Solution Approach 2:
The patent implements feedback by using the injection device's internal sensors or plunger position detection to automatically control the window's visibility state. The system continuously monitors injection progress and provides feedback to the window mechanism, which adjusts code visibility accordingly - concealed during injection and revealed upon completion - ensuring the code is only accessible when the medicament has been fully delivered

AI summary
Aspects of the present invention relate to an injection device configured to receive a medicament container. The injection device comprises movable means, such that before injection an information code is not visible and such that during or after injection the movable means moves to allow the code to be visible.
