The development of an improved autoinjector assembly that includes interchangeable drug capsules and a reusable drug delivery holder, allowing for easy interoperability and enabling self-administration or administration by minimally trained users.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If current autoinjector technology is used, then single dose delivery is achieved, but multiple medications cannot be delivered and adaptability to combat conditions is limited
Solution Approach 1:
The autoinjector is divided into separate functional modules: a reusable driver unit and interchangeable drug capsules. Each capsule contains a specific medication and is designed to snap into the driver unit, allowing different medications to be swapped without modifying the main device structure. This segmentation enables the system to deliver multiple medications while keeping the core device simple and manageable.
Solution Approach 2:
The driver unit is designed with universal compatibility to work with multiple types of drug capsules. The standardized interface and actuation mechanism allow a single driver unit to administer different medications (e.g., antibiotics, analgesics, anticonvulsants) by simply changing the capsule, providing multi-functionality without increasing overall device complexity.
2Ease of operation
If traditional IV administration is used, then accurate medication delivery is achieved, but personnel and time requirements increase
Solution Approach 1:
The autoinjector is designed to be self-actuating through a spring-loaded mechanism that automatically injects the medication when the user activates the device. The user simply attaches the device to the injection site and triggers the mechanism, eliminating the need for skilled personnel to manually control the injection process. This self-service capability significantly reduces the time and expertise required for administration.
3Ease of operation
If oral administration is used, then medication delivery is simplified, but compliance decreases when patients cannot swallow
Solution Approach 1:
The system replaces the mechanical act of swallowing with an automated injection mechanism. Instead of requiring the patient to swallow pills or liquid medication, the autoinjector delivers the medication directly into the muscle or subcutaneous tissue through a needle, bypassing the gastrointestinal tract entirely. This substitution ensures reliable administration regardless of the patient's ability to swallow.
4Adaptability or versatility
If single preloaded dose autoinjector is used, then device simplicity is maintained, but multiple medications cannot be delivered
Solution Approach 1:
The autoinjector system is segmented into a permanent driver unit and removable drug capsules. The driver unit contains the mechanical and electronic components for delivery, while each drug capsule is a separate, self-contained unit with a specific medication. This segmentation allows the system to carry multiple different medications by simply changing capsules, without requiring a completely different device for each medication type.
Solution Approach 2:
Different drug capsules are pre-loaded with specific medications during manufacturing and sealed to maintain sterility and stability. The capsules are designed to be pre-assembled with the correct dosage and formulation, so users do not need to prepare or configure anything before administration. This preliminary preparation enables the delivery of multiple medications while keeping the user interface simple.
