Injection Closure Cap Locking for Electronic Module Recycling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing injection devices face challenges in recycling and waste management due to the integration of electronic modules, which require separate treatment from mechanical components, and there is a need for features that facilitate the separation and recycling of these modules.
Innovation Solution
The injection device incorporates a closure cap with a mechanical interface that securely attaches to the device before use and can be easily released after use, featuring a locking plate and couplings to ensure the cap cannot be removed during operation, allowing for the separation of electronic components for recycling.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If electronic modules are integrated into the injection device, then functionality and user interaction are improved, but waste management and recycling become more difficult
Solution Approach 1:
The device is divided into separable modules: a reusable mechanical injection mechanism and a disposable closure cap containing electronic components. This segmentation allows electronic modules to be easily separated for specialized recycling while maintaining enhanced functionality during use.
2Reliability
If the closure cap is securely attached to protect electronic components, then reliability is improved, but ease of removal for recycling deteriorates
Solution Approach 1:
The mechanical interface transitions from a locked state during use to an unlocked state for removal. The interface includes features like disengageable locking elements and rotational release mechanisms that maintain secure attachment during operation but allow easy removal when needed for recycling.
3Adaptability or versatility
If additional electronic modules are added to the device, then adaptability is improved, but device complexity increases
Solution Approach 1:
Electronic modules are consolidated within the closure cap as an integrated electronic module housing, separating them from the mechanical injection mechanism. This modular approach manages complexity by grouping electronic components together while maintaining clear functional boundaries between mechanical and electronic systems.

AI summary
An injection device for delivery of a fluid medicament including a housing (2) defining a longitudinal axis and enclosing an injection mechanism. An end cap (12) is fixed to the housing (2) thereby delimiting the injection mechanism in a proximal direction. A closure cap (17) closes the injection device (20) and is connected to the end cap (12) by a mechanical interface (12e, 12f, 17a) configured to be released by rotating the closure cap (17) relative to the housing (2) around the longitudinal axis. A locking plate (16c) is positioned between the closure cap (17) and the end cap (12), and the closure cap (17) is coupled to the locking plate (16c) by a first coupling (17b, 16d) and the locking plate (16c) is coupled to the end cap (12) by a second coupling (16f, 12d) thereby preventing rotation of the closure cap (17) with respect to the housing (2).
