Injection Device Housing With Integrated Magnifier
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing drug delivery devices, such as pen-type injectors, face challenges in providing clear visual information about medicament contents, especially for patients with impaired vision, due to limited space on small medicament containers, making it difficult to read labels and determine filling levels.
Innovation Solution
An elongated housing component with a magnifier integrated into the sidewall, which enhances the visibility of labels and scales on medicament containers by providing optical magnification, allowing for easier reading of information from outside the device.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the medicament container is made small to reduce device size, then the device becomes more compact and portable, but the legibility of labels and visual information on the container deteriorates
Solution Approach 1:
A magnifier is introduced as an intermediary optical element between the user's eye and the label on the medicament container. The magnifier is integrated into the housing component and provides optical magnification of the label area, allowing small containers to maintain good legibility. This mediator resolves the contradiction by enabling clear viewing of small text without increasing the container size.
2Device complexity
If the medicament container is made small to fit in compact housing, then the device complexity is reduced, but the visual information display space is insufficient
Solution Approach 1:
The housing component is designed with a localized magnifying optical element at the specific position where label viewing is needed. This local quality enhancement allows the housing to maintain overall simplicity while providing enhanced visual capability at the critical label viewing area. The magnifier is integrated into the housing wall, creating a local optical enhancement without complicating the overall housing structure.
3Illumination intensity
If transparent housing material is used to enable visual inspection, then the visibility of medicament content is improved, but the legibility of labels on small containers remains insufficient
Solution Approach 1:
The magnifier serves as an intermediary optical device that specifically addresses label readability. While the transparent housing material enables general visibility of the medicament content, the magnifier provides the additional optical power needed to resolve fine label text. This combination allows both content visibility and label legibility to be achieved simultaneously.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Improves legibility and patient safety by enabling clearer visualization of medicament information, even for small containers, without significant modifications to existing injection devices.
Implementation Method 1
The magnifier is operable to increase a visual appearance of at least a portion of the medicament container when arranged inside the hollow interior space of the body
