Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current auto-injector devices lack control over the delivery of liquid medicaments, particularly in terms of temperature and injection rate, which can affect the efficacy and safety of drug administration, and there is a need for improved monitoring and auditing of the delivery process.
Innovation Solution
The development of electronic injector assemblies with disposable dose modules that allow for controlled delivery of liquid medicaments, including temperature detection and rate control, using a drive mechanism with motors and sensors to ensure precise injection, and a control system for monitoring and auditing the delivery process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If automatic injector devices are used for parenteral delivery of liquid medicament, then convenient self-administration is achieved, but control over delivery temperature and injection rate is lost
Solution Approach 1:
The system incorporates temperature sensors that continuously monitor the temperature of the medicament and injection site, providing feedback to the control system. The control system adjusts the injection parameters based on this feedback to maintain optimal delivery temperature while preserving the automatic operation and convenience of self-administration.
Solution Approach 2:
The injection rate is made dynamically adjustable through the control system that can modulate the plunger movement based on real-time conditions. The system transitions from static, fixed-rate injection to dynamic, controlled-rate injection while maintaining automatic operation, allowing precise control over delivery parameters without compromising ease of use.
2Device complexity
If conventional auto-injectors are used, then simple device structure is maintained, but monitoring and auditing of delivery process is insufficient
Solution Approach 1:
Electronic components and sensors are introduced as intermediary elements between the mechanical injection system and the control/monitoring system. These intermediaries collect and transmit data about the delivery process, enabling comprehensive monitoring and auditing while keeping the core mechanical injection structure relatively simple.
Solution Approach 2:
Manual monitoring methods are replaced with electronic sensing and data collection systems. Instead of relying on mechanical simplicity, the system uses electronic intermediaries to capture, process, and store delivery information, enabling thorough auditing while maintaining a relatively straightforward mechanical injection mechanism.
3Reliability
If controlled delivery of liquid medicament is implemented, then injection safety and efficacy are improved, but device complexity increases
Solution Approach 1:
The control system is designed to perform multiple functions including temperature monitoring, injection rate control, delivery auditing, and data storage within a single integrated platform. This multi-functionality approach improves reliability and safety while minimizing the increase in device complexity by consolidating control functions rather than adding separate systems for each function.
