Drug Delivery Device with Integrated Extendable Display
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drug delivery devices, such as pen-type injectors, often require user support for proper handling due to the risk of inappropriate use when instruction manuals are lost or untraceable, especially in long-term use or when dealing with multiple devices, leading to potential incorrect dosing and safety issues.
Innovation Solution
A drug delivery device with a moveable display element that provides essential information on demand, integrated into the housing component, ensuring that product-related and therapy-related information remains accessible without compromising the device's design or durability, using mechanisms like rolling, folding, or sliding to reveal information on proper usage and medicinal product details.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If instruction manuals are provided separately, then manufacturing cost is reduced and device simplicity is maintained, but information accessibility deteriorates and risk of loss increases
Solution Approach 1:
The patent integrates the instruction manual directly into the device housing, merging the informational component with the physical device structure. This ensures the manual cannot be lost separately and remains permanently accessible to the user throughout the device's lifespan.
Solution Approach 2:
The instruction manual is nested within the housing structure, specifically integrated into the piston rod assembly. The manual is contained within the hollow piston rod, allowing it to be stored securely inside the device while remaining accessible when needed.
2Ease of operation
If information is always visible, then user guidance is improved, but device compactness and aesthetic design deteriorate
Solution Approach 1:
The patent implements a dynamic information display system where the instruction manual can be moved between a concealed position (stored within the piston rod) and a visible position (extended from the device). This allows the device to adapt its information visibility based on user needs while maintaining compact appearance during storage or transport.
Solution Approach 2:
The instruction manual is segmented into a separate, movable component that can be independently positioned. The manual is attached to the piston rod in a way that allows it to be extended outward for reading while the rest of the device remains intact and compact.
3Device complexity
If device structure is simplified, then manufacturing cost is reduced, but information integration capability deteriorates
Solution Approach 1:
The piston rod serves multiple functions: it acts as the mechanical component for dose dispensing and simultaneously serves as the housing for the instruction manual. This multi-functionality integrates information storage into an existing structural element without adding separate dedicated components, thereby maintaining structural simplicity while enhancing adaptability.

AI summary
The present invention relates to a drug delivery device for dispensing of a dose of a medicinal product, comprising: a housing having at least one housing component (100; 200; 300) a cartridge comprising the medicinal product, - a dose dispensing mechanism operably engaged with the cartridge for setting and/or dispensing of a predefined dose of the medicinal product, and a display element (102; 202; 302) being movably disposed relative to the at least one housing component (100; 200; 300), wherein the display element (102; 202; 302) and the housing component (100; 200; 300) are mutually moveable for selectively concealing and/or revealing information provided on the display element (102; 202; 302).
