Drug Injection Device Controller with Gamified Display Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional pharmaceutical injection devices require patients, especially children, to manually insert needles, leading to reluctance in adhering to scheduled injections, which can diminish therapeutic effectiveness.
Innovation Solution
A pharmaceutical injection device with a controller that updates and combines display content based on usage, providing a engaging interface to encourage regular injections by displaying a 'finished product' after a set number of successful injections, such as a series of robots assembled over time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If the device allows manual needle insertion by the patient, then the patient can easily administer injections themselves, but children in particular dislike this process leading to poor adherence to scheduled injections
Solution Approach 1:
The device incorporates a display section that provides visual feedback through images and animations to motivate children. The controller updates display content based on injection progress, showing accumulated images that represent completed injections, creating a positive reinforcement system that encourages adherence to the injection schedule.
Solution Approach 2:
The display section dynamically changes its output based on the number of injections administered. The controller updates the display content to show different images or animation states corresponding to different injection milestones, transforming the static display into a dynamic motivational tool that adapts to usage patterns.
2Ease of operation
If the display shows simple injection status, then the device remains simple to operate, but it fails to engage children and motivate regular use
Solution Approach 1:
The display section serves multiple functions: it shows basic injection status information while simultaneously displaying motivational images and animations. The same display hardware provides both functional information and emotional engagement, making the device versatile in addressing both operational simplicity and child engagement needs.
Solution Approach 2:
The controller acts as an intermediary that processes injection data and translates it into engaging visual representations. It mediates between the simple mechanical injection action and the complex motivational display output, converting basic usage data into compelling visual narratives that engage children without complicating the actual injection process.

AI summary
This pharmaceutical injection device comprises a main body case (2) that has an injection needle insertion and retraction opening (1); a pharmaceutical syringe mounting portion (3) that is provided within the main body case (2); a piston (5) that is provided movably with respect to a pharmaceutical syringe (4) that is mounted to the pharmaceutical syringe mounting portion (3); a drive mechanism (6) that drives the piston (5); a controller (7) that is electrically connected to the drive mechanism (6); and a display section (35) that is electrically connected to the controller (7). The controller (7) updates the display content that is displayed on the display section (35) according to the number of times the drive mechanism (6) has been driven, and saves this updated display content in a memory (51), so that when the drive mechanism (6) has been driven a specific number of times, the display contents during the various instances of drive that were saved in the memory (51) are combined.
