Folding Finger Pad for Medication Delivery Device
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Medication delivery devices, such as syringes and pen-type devices, often pose handling difficulties for users with large hands or movement disorders due to small finger pads, and require inconvenient manual assembly of accessories for improved handling.
Innovation Solution
A medication delivery device with folding finger pads that can be moved from a hinged position for storage and transportation to a second position for use, providing improved grip and preventing sliding movement, integrated into the manufacturing process of conventional devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the flange is relatively small to maintain device compactness, then the device size is reduced, but the syringe becomes difficult to handle for users with large hands or movement disorders
Solution Approach 1:
The finger pad is designed as a movable component that can transition between a first position (flush with the outside wall) and a second position (extended outward). This dynamic configuration allows the device to adapt its handling characteristics - compact during storage and expanded during use - resolving the contradiction between small size and ease of handling.
Solution Approach 2:
The finger pad is separated from the main body as a distinct movable component connected via a hinge. This segmentation allows the finger pad to be positioned independently - retracted when not needed and extended when needed - enabling the device to maintain compact size while providing enhanced handling when required.
2Ease of operation
If a separate accessory is supplied to improve handling, then handling comfort is improved, but the device requires manual assembly which is inconvenient and difficult for users with large hands or movement disorders
Solution Approach 1:
The finger pad functionality that was previously provided by a separate accessory is now integrated directly into the device structure. The finger pad is connected to the outside wall via a hinge, combining the benefits of an extended finger pad with the simplicity of a single-device construction, eliminating the need for separate accessories and their complex assembly.
Solution Approach 2:
The device provides its own handling enhancement feature (the extendable finger pad) as an integral part of its structure. Users do not need to attach separate accessories - the finger pad is already attached via a hinge and can be easily positioned by the user themselves, making the device self-sufficient and eliminating complex assembly requirements.
3Ease of operation
If the finger pad is extended outward to improve grip, then handling comfort is improved, but the device occupies more space during storage and transportation
Solution Approach 1:
The finger pad transitions dynamically between retracted and extended positions. During storage and transportation, the finger pad is positioned flush with the outside wall, minimizing the device volume. During use, the finger pad can be extended outward to provide improved grip comfort, thus resolving the space-handling contradiction through dynamic reconfiguration.
Solution Approach 2:
By separating the finger pad as a movable component connected via hinge, the design allows the finger pad to be positioned independently. When retracted, the device maintains a compact form factor for storage. When extended, the finger pad provides enhanced grip without permanently increasing the device's storage volume, as the extended position is only occupied during actual use.
