Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing self-injection devices for medicaments pose challenges such as fear and anxiety due to the risk of incomplete dosing, pain, needlestick injuries, and difficulty in operating the device, especially for users with little medical knowledge or experience.
Innovation Solution
A resettable injection training device that provides multi-sensory feedback, including visual, auditory, and tactile cues, to simulate the injection process safely and repeatedly, allowing users to practice and become familiar with the self-injection process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If self-injection devices are used for medicament delivery, then convenience and automation of drug delivery are improved, but user anxiety and fear of incomplete dosing or needlestick injuries increase
Solution Approach 1:
The patent creates a training device that is a simplified copy of the actual auto-injection device. This copy replicates the key operational features (penetration phase, injection phase, ejection phase) without containing actual medication or sharp needles, allowing users to practice the injection process safely and build confidence before using the real device.
Solution Approach 2:
The training device incorporates multi-sensory feedback mechanisms including visual feedback (colored indicators showing device state), tactile feedback (vibrations during different phases), and auditory feedback (clicks indicating phase transitions). This feedback helps users understand the injection process and reduces anxiety by providing clear information about device status.
2Reliability
If training devices are used to reduce user anxiety, then user confidence and accuracy improve, but device complexity increases due to multiple feedback mechanisms
Solution Approach 1:
The training device divides the injection process into distinct phases (penetration, injection, ejection) with clear visual indicators for each phase. This segmentation helps users understand the sequence of events and reduces cognitive load, making the complex process more manageable and less anxiety-inducing.
Solution Approach 2:
The device uses color changes in visual indicators to communicate device state and phase information. This provides intuitive visual feedback that is easy to understand at a glance, reducing the need for complex displays or interfaces while still providing comprehensive information to the user.
3Loss of information
If multi-sensory feedback is provided during training, then user understanding and confidence improve, but manufacturing cost and device complexity increase
Solution Approach 1:
The training device uses inexpensive, simple components for feedback mechanisms such as colored windows, vibration motors, and click mechanisms. These are designed to be disposable or easily replaceable, reducing manufacturing costs while still providing effective training functionality.
Solution Approach 2:
The patent uses simple intermediary elements like colored indicators and vibration motors that translate complex internal device states into easily understandable sensory signals. These intermediaries provide effective communication between the device and user without requiring complex electronics or expensive components.
