Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Drug delivery devices, such as on-body and hand-held injectors, can appear complicated and intimidating to patients unfamiliar with them, making it difficult for users to determine when the device is ready for use and to understand the next steps in the injection process.
Innovation Solution
A drug delivery device equipped with a sensor that detects contact with the patient's body and triggers a user interface to change its state, indicating readiness for injection through external changes like motion, sound, or light, guiding the user through the next steps in the process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a drug delivery device includes multiple operational steps and components, then the device can perform complete injection functions, but the device appears complicated and intimidating to patients
Solution Approach 1:
The device incorporates sensors that detect patient body contact and provide feedback signals to a control system, which then guides the user through operational steps via a user interface. This feedback mechanism automates complexity management while maintaining complete injection functions.
Solution Approach 2:
The device performs self-diagnosis and self-guidance through integrated sensors and control systems that automatically detect preparation status and guide users through necessary steps, reducing the perceived complexity while maintaining functional completeness.
2Loss of information
If the device provides detailed operational guidance, then users can understand next steps, but the interface becomes more complex
Solution Approach 1:
The user interface provides dynamic feedback based on sensor inputs, showing users only the relevant next steps in the injection process. This contextual information delivery maintains clarity without requiring a permanently complex interface structure.
Solution Approach 2:
The user interface dynamically adapts its displayed information based on the current operational state detected by sensors, presenting simplified step-by-step guidance that evolves as the injection process progresses, rather than displaying all possible information simultaneously.
3Ease of operation
If the device automatically detects body contact, then readiness indication is improved, but the device requires additional sensors and control systems
Solution Approach 1:
The device uses integrated sensors to automatically detect body contact and self-determine readiness status without requiring manual user assessment. This self-service capability improves ease of operation while the sensors are incorporated as standard components in the overall device architecture.
Data Source
AI summary
A drug delivery device includes a container for storing a drug, the container having a stopper for expelling the drug; an injection drive comprising an energy source for directly or indirectly acting on the stopper to expel the drug; a sensor for detecting contact between the drug delivery device and a body of a patient; and a user interface (UI) for activating or causing the activation of the injection drive. The device is operative for drawing attention to the UI, if the sensor detects contact between the drug delivery device and the body of the patient, to thereby indicate that the injection drive is ready to be activated, which activation is the next step in the drug administration process.
